Combining longitudinal postcode-level data on charitable donations made through a UK giving portal with publicly available data on local crime and neighborhood characteristics, we study the relationship between local crime and local residents’ charitable giving and we investigate the possible mechanisms underlying this relationship. An increase in local crime corresponds to a sizeable increase in the overall size of unscheduled charitable donations. This effect is mainly driven by the responses of female and gender unclassified donors. Donation responses also reflect postcode variation in socio-economic characteristics, levels of mental health, and political leanings, but mainly so for female and gender-unidentified donors.

Politicians often use red herrings to distract voters from scandals. When do such red herrings succeed? I develop a model in which an incumbent runs for re-election and potentially faces a scandal. Some incumbents enjoy telling “tales” (attention-grabbing stories) while others use tales to distract voters from the scandal. Multiple equilibria can arise: one with a norm of tale-telling in which red herrings succeed and another with a norm against tale-telling in which they fail. Increased media attention to tales has a nonmonotonic effect, facilitating red herrings at low attention levels, but serving a disciplinary function at high levels.

We study the relationship between exposure to historical conflict involving heavy weaponry and male-favoring gender norms. We argue that the physical nature of such conflict produced cultural norms favoring males and male offspring. We focus on spatial variation in gender norms across India, a dynamic developing economy in which gender inequality persists. We show robust evidence that areas with high exposure to pre-colonial conflict are significantly more likely to exhibit male favoring gender norms as measured by male-biased sex ratios and crimes against women. We document how conflict-related gender norms have been transmitted over time via male-favoring folkloric traditions, the gender identity of temple gods, and male-biased marriage practices, and have been transmitted across space by migrants originally from areas with high conflict exposure.

A substantial body of literature has shown that women shy away from competition against men, which has been put forward as an explanation for the significant gender differences observed in career promotions and salary negotiations. It is therefore of crucial importance to understand the conditions under which the gender gap in competitiveness can be reduced. In this study, we explore the role of priming. Our findings replicate previous work showing that, in the absence of primes, women compete less than men. By contrast, introducing a priming task can eliminate gender disparities in competitiveness, ceteris paribus; however, the effects are stronger when neutral primes are used. We perform sentiment analysis and attribute this to the more negative emotions triggered in the neutral priming condition, making women more competitive. Overall, our results indicate that costless and simple tools such as priming can be adopted by organisations aiming at reducing gender inequalities in the workplace.

We develop a model of strategic voting in a spatial setting with multiple candidates when voters have both expressive and instrumental concerns. The model endogenizes the strategic coordination of voters, yet is flexible enough to allow the analysis of political platform competition by policy-motivated candidates. We characterize all strategic voting equilibria in a three-candidate setting. Highlighting the utility of our approach, we analyze a setting with two mainstream and a spoiler candidate, showing that the spoiler can gain from entering, even though she has no chance of winning the election and reduces the winning probability of her preferred mainstream candidate

In this paper, we estimate the causal effect of transitory individual-level health shocks on schooling outcomes in Brazil. We focus on dengue fever, which, despite putting half of the world’s population at risk, has received relatively little attention, possibly due to its low mortality. We link individual register data on dengue infections with detailed individual records from the Brazilian school census and use a fixed effects estimation strategy to estimate the effect of dengue infections on grade retention and dropout. We find that dengue infections during the school year have a substantial negative effect on measures of student success, with an increase in grade retention of 3.5 percent and an increase in dropout of 4.6 percent. Using information on monthly attendance from the monitoring system of conditionalities of the Brazilian cash transfer Bolsa Famılia, we provide evidence that infections reduce school attendance.

Formal conceptions of state capacity have mostly focused on indirect measures of state capacity – by, for instance, using the state’s fiscal or extractive capacity as a proxy for its overall capacity. Yet, this input or extractive view of state capacity falls short, especially since cross-country empirical evidence suggests that similar levels of fiscal capacity, measured by tax revenues as a percentage of GDP, can produce starkly different outputs – both in classic economic terms and in broader terms that citizens would recognize as desirable outcomes, including quality of life, health, security, equality of opportunity, and intergenerational mobility. This paper argues that a central step towards addressing these shortcomings of the conventional view is to account for a crucial and largely ignored boundary of the state or dimension of state capacity: its capacity to gather, process, and deploy information in its conduct of fiscal policy. Specifically, we study how the presence or lack of such informational capacity constrains governments in responding to crises, such as the recent energy price shock. Our framework provides the analytical toolkit to examine how the informational boundary of the state shapes the incentives for policymakers to resort to untargeted and/or distortionary policy instruments, as opposed to targeted and non-distortionary ones, in responding to crises. The policy response to the energy crisis following the invasion of Ukraine provides the empirical context upon which we bring this theoretical framework to bear on data, though the latter can be straightforwardly extended to other recent crises.

Impact assessments (IAs) of government regulatory policy proposals set out their expected costs, benefits and risks and who is likely to face those impacts. In the UK, primary legislation can confer powers on Government ministers and other bodies to enact Statutory Instruments (SIs) and other secondary legislation. Because SIs have the same effect as Acts of Parliament, but face significantly less scrutiny, there has been a trend to increase the use of this mechanism and to use them for areas of policy or principle, rather than purely administrative procedures. However, the different timing and treatment of primary and secondary legislation has important implications for the assessment of the impacts of the proposed measures in IAs. This paper outlines the rationale for a compound (primary and secondary) approach to introducing legislation, identifies different types of subordination and considers the implications for estimating their expected impacts in an IA - particularly when the assessment of the secondary measure happens after some of the uncertainty related to the possible outcomes of the primary measure has been resolved and this can be taken into account in the secondary decision(s). It points out the limitations of the conventional NPV-based approach to assessing the impacts of compound measures and proposes the use of a real options approach to IAs to address this concern. In particular it suggests that the real options approach should be used in cases where there are; uncertain outcomes, different possible timings, irreversible policy decisions and distortions due to the use of standard discount rates. Primary legislation creates the opportunity but not the obligation to pursue secondary measures and should be assessed taking these future options into account.

I investigate the motives behind economic growth under a dictatorship, exploring the tradeoff between pursuing higher future gains, which come with growing threats from the demand for democracy from the emerging middle class, and accepting lower gains for a relatively more stable regime. I propose a model where a dictator invests and acquires a rent, citizens educate their children for skilled jobs, and these children adopt democratic values through education. I find that a dictator invests in an underdeveloped economy for future gains. As the economy matures, investment decreases because more citizens get democratic values from higher education. Democracy follows an opposite investment trend: little investment is made when the economy is underdeveloped, but more investment is made as it develops. The analysis is generalised to cases where the dictator is legitimised by higher economic growth than in democracies, and where the dictator oppresses the middle class through high taxation.

Using firm-level data from France, we document that the shift of economic activity from manufacturing to services over the last few decades has been urban-biased : structural change has been more pronounced in areas with higher population density. This bias can be accounted for by the location choices of large services firms that sort into big cities and large manufacturing firms that increasingly locate in suburban and rural areas. Motivated by these findings, we estimate a structural model of city formation with heterogeneous firms and international trade. We find that agglomeration economies have strengthened for services but weakened for manufacturing. This divergence is a key driver of the urban bias but it dampens aggregate structural change. Rising manufacturing productivity and falling international trade costs further contribute to the growth of large services firms in the densest urban areas, boosting services productivity and services exports, but also land prices.

This paper estimates the size of the media multiplier, an easily generalizable model-based measure of how far media coverage magnifies the economic response to shocks. We combine monthly aggregated and anonymized credit card activity data from 114 card issuing countries in 5 destination countries with a large corpus of news coverage in issuing countries reporting on violent events in the destinations. To define and quantify the media multiplier we estimate a model in which latent beliefs, shaped by either events or news coverage, drive card activity. According to the model, media coverage can more than triple the economic impact of an event. We document, through our model, that this effect is highly heterogenous and depends on the broader media representation of countries in each others news. We speculate about the role of the media in driving international travel patterns an.

How domestic constituents respond to signals of weakness in foreign wars remains an important question in international relations. In this paper, we study the impact of battlefield casualties and media coverage on public demand for war termination. To identify the effect of troop fatalities, we leverage the otherwise exogenous timing of survey collection across 26,776 respondents from nine members of the International Security Assistance Force (ISAF) in Afghanistan. Quasi-experimental evidence demonstrates that battlefield casualties increase coverage of the Afghan conflict and public demand for withdrawal, with heterogeneous effects consistent with an original theoretical argument. Evidence from a survey experiment replicates the main results. To shed light on the media mechanism, we leverage a news pressure design and find that major sporting matches occurring around the time of battlefield casualties drive down subsequent coverage, and significantly weaken the effect of casualties on support for war termination. These results highlight the crucial role that media play in shaping public support for foreign military interventions.

This paper analyses the consumer impacts of arbitrage focusing on the significant role of internet platforms as monopolistic arbitrageurs between essentially competitive sub-markets that have not been previously linked. As arbitrageurs, there is the potential for them to create consumer benefit, but for a series of reasons, we show that consumer welfare may not be enhanced and that particular sections of the community may be disadvantaged by their actions.

The Register of Overseas Entities (ROE) was introduced by the government in Spring 2022 with the commitment that it would require anonymous foreign owners of UK property to reveal their real identities. We use data released by Companies House and HM Land Registry to assess to what extent the ROE is currently delivering on this aim. We identify and quantify several major gaps in the scope and operation of the register and make recommendations for how the register could be improved.

Consider a continuum of independent and identically distributed random variables corresponding to the points of the unit interval [0; 1]. Known technical diffculties are complemented by showing directly that the random sample path is almost surely not a Lebesgue measurable function. This refutes the common claim that, because of some version of the "law of large numbers", the integral of each sample path equals the common mean of each random variable. To obtain a valid and useful result, we apply to the continuum of random variables the Monte Carlo method of numerical integration based on limits as the sample size tends to infinity of empirical finite sample averages of the realized random values. The resulting "Monte Carlo integral" is almost surely a degenerate random variable concentrated on the mean. A suitably modified version works when the different indexed random variables are merely independent with cumulative distribution functions that are measurable w.r.t. the index. Further generalizations to Monte Carlo integrals of conditionally independent random variables result, under conditions discussed in Hammond and Sun (2008, 2021), in non-degenerate random integrals that are measurable w.r.t. the conditioning -algebra.

Can weakened religiosity lead to the rise of totalitarianism? The Nazi Party set itself up as a political religion, emphasizing redemption, sacrifice, rituals, and communal spirit. This had a major impact on its success: Where the Christian Church only had shallow roots, the Nazis received higher electoral support and saw more party entry. shallow Christianity reflects the geography of medieval Christianization and the strength of pagan practices, which we use as sources of exogenous variation. We also find predictive power at the individual level : Within each municipality, the likelihood of joining the Nazi Party was higher for those with less Christian first names.

We show that the spread of the railway network slowed the decline of fertilityin Europe during the late nineteenth and early twentieth centuries. We construct novel data on market access across sub-national regions in Europe and use both a panel fixed effects approach and an instrumental variables strategy that leverages variation in market access stemming from access to distant markets. We find that greater market access predicts higher fertility, with a standardized magnitude of 0.14. Consistent with an interpretation that market access increased fertility by raising incomes relative to the returns to child quality and the opportunity cost of childbearing, we show that our results are driven by locations that achieved higher levels of income per capita despite lagging in human capital and female labor force participation.

Recent empirical evidence contends that meritocratic ideals are mainly a Western phenomenon. Intriguingly, the Chinese people appear to not differentiate between merit- and luck-based inequalities, despite their rich historical legacy of meritocratic institutions. We propose that this phenomenon might be due to the Chinese public’s greater adherence towards the status quo. In order to test this hypothesis, we run an incentivized redistribution experiment with elite university students in China and France, by varying the initial split of payoffs between two real-life workers to redistribute from. We show that Chinese respondents consistently and significantly choose more non-redistribution (playing the status quo) across both highly unequal and relatively equal status quo scenarios than our French respondents. Additionally, we also show that the Chinese sample does differentiate between merit- and luck-based inequalities, and does not redistribute less than the French absent status quo conformity. Ultimately, we contend that such a phenomenon is indicative of low political agency rather than apathy, inattention, or libertarian beliefs among the Chinese. Notably, our findings show that Chinese individuals’ conformity to the status quo is particularly pronounced among those from families of working-class and farming backgrounds, while it is conspicuously absent among individuals whose families have closer ties to the private sector.

When is receiving positive news regarding future technological advancements most impactful on the economy: during recessions or economic booms? A recession might represent an opportune time for investing in relatively cheaper, productivity enhancing activities. However, tighter financial constraints during recessions might hinder the ability to secure funds for these activities. We explore this dichotomy by exploiting patent-based innovation shocks, which are constructed using changes in stock market valuations of firms that obtain patent grants. We find that aggregate patent-based innovation shocks have a greater impact on the economy during recessions, leading to a more significant increase in private investment. Additionally, our exploration of firm-level data uncovers supporting evidence that firms tend to boost their capital investment and R&D expenditures in response to these innovation shocks, particularly during recessions. The financial constraints of firms play a crucial role, with capital investments by firms with low default risk driving the larger impact observed during recessions

We use the elements of a macroeconomic production function—physical capital, human capital, labor, and technology—together with standard growth models to frame the role of religion in economic growth. Unifying a growing literature, we argue that religion can enhance or impinge upon economic growth through all four elements because it shapes individual preferences, societal norms, and institutions. Religion affects physical capital accumulation by influencing thrift and financial development. It affects human capital through both religious and secular education. It affects population and labor by influencing work effort, fertility, and the demographic transition. And it affects total factor productivity by constraining or unleashing technological change and through rituals, legal institutions, political economy, and conflict. Synthesizing a disjoint literature in this way opens many interesting directions for future research.

Several modern textbooks report that, thanks to the availability of heteroskedasticity robust standard errors, one observes the near-death of Weighted Least Squares (WLS) in cross-sectional applied work. We argue in this paper that it is actually possible to estimate regression parameters at least as precisely as Ordinary Least Squares (OLS) and WLS, even when using a misspecified parametric model for conditional heteroskedasticity. Our analysis is valid for a general regression framework (including Instrumental Variables and Nonlinear Regression) as long as the regression is de ned by a conditional expectation condition. The key is to acknowledge, as first pointed out by Cragg (1992) that, when the user-specific heteroskedasticity model is misspecified, WLS has to be modified depending on a choice of some univariate target for estimation. Moreover, targeted WLS can be improved by properly combining moment equations for OLS and WLS respectively. Efficient GMM must be regularized to take into account the possible multicollinearity of estimating equations when errors terms are actually nearly homoscedastic.

Social media has changed the structure of mass communication. In this paper we explore its role in influencing political donations. Using a daily dataset of campaign contributions and Twitter activity for US Members of Congress 2019-2020, we find that attention on Twitter (as measured by likes) is positively correlated with the amount of daily small donations received. However, this is not true for everybody: the impact on campaign donations is highly skewed, indicating very concentrated returns to attention that are in line with a ‘winner-takes-all’ market. Our results are confirmed in a geography-based causal design linking member’s donations across states.

Economic warfare was a product of the total wars of the twentieth century. Four lessons are discussed: (1) Modern economies are resilient under attack. (2) The action of economic warfare is slow. (3) Economic warfare is powerful—eventually. (4) The threat of economic warfare is also powerful—although not always as hoped. To conclude, economic warfare belongs to wars of attrition. In such wars, economic and military measures are complements, not substitutes.

For path-breaking insights on how prices can guide the efficient allocation of resources and on how innovation and investment can spur economic growth, Adam Smith is justly renowned. He was, however, well aware of problems posed by market dominance – specifically in banking and, more generally, wherever getting to the scale that delivers increasing returns leads to monopolistic behaviour. For the historical record, we draw on the recent wide-ranging survey by Acemoglu and Johnson on how the benefits of innovation have been spread across society since the Industrial Revolution. We also consider these issues in the context of geo-political competition.

We investigate the impacts of a perinatal psychosocial intervention on trajectories of maternal mental health and child skills, from birth to age 3. We find improved maternal mental health and functioning (0.17 – 0.29 SD), modest but imprecisely estimated improvements in parental investments (0.07 to 0.11 SD), and transitory improvements in child socioemotional development (0.06 to 0.39 SD). We also find negligible influence of the intervention on physical health and cognitive development. Estimates of a skill production function reveal that the intervention is associated with reduced productivity of maternal mental health and narrowed depression gaps in mother and child outcomes.

This paper documents that surprise election outcomes – measured as deviations between realised vote shares and expected vote shares based on a newly constructed dataset of opinion polls and party and candidate vote shares close to election day – are causing non-negligible short-term contractions in economic activity. We find that, on average, a percentage point higher surprise is associated with a 0.37 percentage point lower year-on- year growth rate one year after the election. These effects are only present in countries with strong democracies and seem to operate mainly through increased economic policy uncertainty and lower investment growth over a window of up to eight quarters after an election. In addition, surprise performances of left-wing political parties and in elections with transitions to left-wing governments (pre-defined from the Parlgov Database) are associated with the largest effects on the economy.

Which households are most affected by energy price shocks? What can we learn about the distributional implications of carbon taxes? How do interventions in energy markets affect these patterns? This paper introduces a measurement framework that leverages granular property-level data representing more than 50% of the English and Welsh housing stock. We use this ex-ante measurement framework to investigate these questions and set out an empirical evaluation framework to study the causal effects of the energy crisis more broadly. We find that the energy price shock has a more pronounced effect on relatively more affluent areas highlighting the likely progressive impact of carbon taxation. We document that commonly used untargeted interventions in energy markets significantly weaken market price signals for able-to-pay households. Alternative, more targeted policies are cheaper, easily implementable, and could better align energy saving incentives.

Counterfactual predictions are challenging when the policy variable goes beyond its pre-policy support. However, in many cases, information about the policy of interest is available from different (“source”) regions where a similar policy has already been implemented. In this paper, we propose a novel method of using such data from source regions to predict a new policy in a target region. Instead of relying on extrapolation of a structural relationship using a parametric specification, we formulate a transferability condition and construct a synthetic outcome-policy relationship such that it is as close as possible to meeting the condition. The synthetic relationship weighs both the similarity in distributions of observables and in structural relationships. We develop a general procedure to construct asymptotic confidence intervals for counterfactual predictions and prove its asymptotic validity. We then apply our proposal to predict average teenage employment in Texas following a counterfactual increase in the minimum wage.

This paper aims to examine quantitatively and qualitatively the impact of five key general purpose technologies in order to gain insights into what factors may arise in relation to 5G as a potential example. We first attempt a definition of what constitutes a general-purpose technology, providing a potential framework for analysis of impact mechanisms then take this to the five case studies. It is difficult to capture the impacts of such technologies because their scope is broad and commonly a suitable base case from which to measure impact is missing. In addition, there are in each case antecedents and complementary developments which influence their impact. However, our analysis points to a range of factors that must be considered in relation to potential new candidate technologies, including a range of potential governmental interventions.

Surprises in the price of oil futures computed on the day of OPEC announcements have been used as an exogenous measure of shifts in market beliefs about future oil supply to identify shocks to oil supply expectations. I show that these surprises capture not only revisions in market expectations about oil supply, but also revisions in expectations about oil demand. This conflation of supply and demand components invalidates the use of the surprises as an exogenous measure of shocks to oil supply expectations. I show that imposing an additional restriction on the sign of the co-movement between surprises in oil futures and changes in stock prices within the day of the OPEC announcement disentangles the two underlying shocks. Accordingly, I derive two robust instruments for the identification of shocks to oil supply and demand expectations that combine the surprises with this additional sign restriction, and I test them on a set of empirical specifications modelling the oil market and the global economy. A negative shock to oil supply expectations has deep and long-lasting stagflationary effects on global economic conditions that are stronger and more immediate than previously reported. These effects represent a challenge for monetary authorities that seek to stabilise both prices and output. I show that information effects are a prominent feature of the oil market and need to be accounted for when estimating the effects of shocks to oil supply expectations.

We investigate the impact of the political representation of minority groups on the incidence of ethnic conflict in India. We code data on Hindu-Muslim violence and Muslim political representation in India and leverage quasi-random variation in legislator religion generated by the results of close elections. We find that the presence of Muslim legislators results in a large and significant decline in Hindu-Muslim conflict. The average result is driven by richer states and those with greater police strength. Our results suggest that the political empowerment of minority communities can contribute to curbing civil conflict.

Who is targeted by preventive repression and why? In the Soviet Union, the KGB applied a form of low-intensity preventive policing, called profilaktika. Citizens found to be engaging in politically and socially disruptive misdemeanors were invited to discuss their behavior and to receive a warning. Using novel data from Lithuania, a former Soviet republic, in the late 1950s and the 1970s, we study the profile and behaviors of the citizens who became subjects of interest to the KGB. We use topic modeling to investigate the operational focuses of profilaktika. We find that profilaktika began as a way of managing specific threats or “known risks” that arose from the experience of postwar Sovietization. The proportion of “unknown risks” – people without risk factors in their background or personal records – increased by the 1970s. These people were targeted because of their anti-Soviet behaviour, which the KGB attributed to “contagious” foreign influences and the spread of harmful values.

The invasion of Ukraine has led to an unprecedented increase in energy prices in much of Western Europe with policy makers actively intervening in energy markets to cushion the shock. The UK’s policy response stands out: the energy price guarantee (EPG) was entirely untargeted and is, in real terms, much less generous to those living in properties with low energy efficiency. Using granular data and following a documented research approach this paper documents that areas more exposed to the energy price shock saw a notable increase in burglaries and anti-social behaviour: the energy price shock is responsible for a 6 to 10 percent increase in burglaries and a 9 to 24 percent increase in police reported anti-social behaviour between October 2022 to March 2023 inclusive. A quantification of policy alternatives suggests that a more targeted energy support package and/or a more energy efficient housing stock could have resulted in a drastically less pronounced uptick in crime.

This paper examines long-run unconditional convergence of labour productivity in manufacturing across 48 contiguous U.S. states. For that purpose, we construct a detailed panel data set of state industry pairs with over 120 industries covering the period 1880-2007. We find that unconditional 𝛽- convergence in manufacturing productivity was pervasive and rapid – 7.6% per year in 1880-2007 – and that manufacturing accounts for most of the unconditional convergence contribution to overall productivity growth over the long run: 61% in 1880-1940 and 91% in 1958-2007. We also examined broad U.S. regions and found that in the South the contribution of unconditional 𝛽-convergence in manufacturing to aggregate productivity growth before World War II was weak not because of a slower convergence rate but a much smaller manufacturing sector.

Hospitals are under increasing pressure as they bear a growing burden of chronic disease while also dealing with emergency cases that do not all require hospital care. Many countries have responded by introducing alternative facilities that provide 24/7 care for basic and medium-complexity cases. Using administrative data, we investigate impacts of the opening of these intermediate facilities (UPA) in the state of Rio de Janeiro in Brazil. We find that an UPA opening in the catchment area of a hospital reduces hospital outpatient procedures and admissions and that this is associated with improved hospital performance. There is a decline in inpatient mortality, particularly mortality from the more complex conditions that hospitals are best equipped to deal with. There is no discernible change in the risk profile of cases going to hospital, and no concurrent policy changes that can account for these findings. In order to capture displacement effects, we investigate city-level population outcomes. We find that two-thirds of the decline in hospital mortality is offset by deaths in UPAs. Looking at individual death causes, we see a net decline in deaths from congestive heart failure.

We examine the link between a mother’s autonomy - the freedom and ability to think, express, make decisions, and act, independently - and the nutritional status of her children. We design a novel statistical framework that accounts for the cultural and traditional environment to create a measure of maternal autonomy treating this as a latent characteristic that is fixed in the short term. Using data from India, we deal with two econometric challenges: (i) creation and measurement of the ‘autonomy’ index, and (ii) endogeneity caused by selection due to son preference. We find : (i) one standard deviation (SD) higher autonomy score is associated with a 0.16 SD higher Height-for-Age Z-scores (HAZ); and an (ii)10% lower prevalence of stunting (HAZ <-2 SD). The latter is equivalent to the prevention of approximately 300,000 children from stunting, indicating the important role of maternal autonomy.

Information about the share of total income held by the richest 1%, or other top income groups, is increasingly used to discuss inequality levels and trends within and between nations. A top income share is the ratio of the total income held by the top income group divided by total personal income (the ‘income control total’). We compare two approaches to estimating income control totals: the ‘external’ approach used by the World Inequality Database, and an augmented ‘internal’ approach. We argue in favour of the latter, with reference to five desirable properties that a top share series would ideally possess. The choice matters: our augmented ‘internal’ approach yields estimates of the UK top 1% share that are around 2 percentage points higher than the ‘external’ approach.

Market-based environmental regulations are seldom used in developing countries, where pollution is the highest but state capacity is often low. We experimentally evaluate a new particulate matter emissions the first in the world, covering industrial plants in a large Indian city. There are three main findings. First, the market functioned well: permit trade was active and plants obtained permits to meet their compliance obligations almost perfectly. Second, treatment plants, randomly assigned to the emissions market, reduced pollution emissions by 20% to 30%, relative to control plants. Third, the market, holding emissions constant, reduces abatement costs by 11% to 14%. These cost estimates are based on a model that estimates heterogeneous plant marginal abatement costs from plant bids for emissions permits. More broadly, we find that emissions can be reduced at small increases in abatement costs. The pollution market therefore has health benefits that exceed costs by at least twenty-five times.

This review aims to examine (i) the aetiology of obesity ; (ii) how and why a perception of personal responsibility for obesity so dominantly frames this condition and how this mindset leads to stigma ; (iii) the consequences of obesity stigma for people living with obesity, and for the public support for interventions to prevent and manage this condition ; and (iv) potential strategies to diminish our focus on personal responsibility for the development of obesity, to enable a reduction of obesity stigma, and to move towards effective interventions to prevent and manage obesity within the population. Recent Findings We summarise literature which shows that obesity stems from a complex interplay of genetic and environment factors most of which are outside an individual’s control. Despite this, evidence of obesity stigmatisation remains abundant throughout areas of media, entertainment, social media and the internet, advertising, news outlets, and the political and public health landscape. This has damaging consequences including psychological, physical, and socioeconomic harm. Summary Obesity stigma does not prevent obesity. A combined, concerted, and sustained effort from multiple stakeholders and key decision-makers within society is required to dispel myths around personal responsibility for body weight, and to foster more empathy for people living in larger bodies. This also sets the scene for more effective policies and interventions, targeting the social and environmental drivers of health, to ultimately improve population health.

Preserving heritage is an important part of maintaining collective identity for future generations. Yet, in the context of the climate crisis, it is imperative to understand to what extent there is a tangible trade-off between conserving character vis-a-vis averting the worst of climate change – a much more existential threat to those future generations. Studying data for more than half of the English housing stock, I show that conservation area status – a special area based designation to preserve the unique character of a neighborhood – not to be confused with preservation of historic buildings – in England may be responsible for up to 3.2 million tons of avoidable CO2 emissions annually. Using a suite of micro-econometric methods I show that properties in conservation areas have a notable worse energy efficiency; experience lower investment in retrofitting and consume notably higher levels of energy owing to poor energy efficiency. Effect sizes are very consistent comparing engineering based energy consumption estimates with actual consumption data. Effects can be directly attributed to planning requirements for otherwise permitted development that only apply to properties by virtue of them being located inside a conservation area.

Purely affective interaction allows the welfare of an individual to depend on her own actions and on the profile of welfare levels of others. Under an assumption on the structure of mutual affection that we interpret as nonexplosive mutual affection, we show that equilibria of simultaneous-move affective interaction are Pareto optimal independently of whether or not an induced standard game exists. Moreover, if purely affective interaction induces a standard game, then an equilibrium profile of actions is a Nash equilibrium of the game, and this Nash equilibrium and Pareto optimal profile of strategies is locally dominan.

Special interest influence via lobbying is increasingly controversial and legislative efforts to deal with this issue have centred on the principle of transparency. In this paper we evaluate the effectiveness of the current regulatory framework provided by the US Lobbying Disclosure Act (LDA). Specifically, we study the role of ex-Congressional officials who join US lobbying firms in positions that could be related to lobbying activity but without officially registering as lobbyists themselves. We find that firm lobbying revenues increase significantly when these potential ‘shadow lobbyists’ join, with effects in the range of 10-20%. This shadow lobbyist revenue effect is comparable to the effect of a registered lobbyist at the median of the industry skill distribution. As such, it is challenging to reconcile the measured shadow lobbyist effect with the 20% working time threshold for registering as a lobbyist. Based on our estimates, the unaccounted for contributions of unregistered lobbyists can be valued at $149 million USD in revenue terms and this effect is concentrated within the industry’s largest and most active firms.

We study the provision of information by local governments that supports individual compliance with nationwide regulation, and how this provision relates to the electoral process. We use information about individual mobility (compliance with the lockdown) and Facebook posts by Italian local governments during the Covid 19 pandemic. We show that in municipalities where mayors were up for reelection, local governments provided significantly more covid-related information. This information caused a significant decrease in mobility and excess mortality. However, these effects seem to arise only in the northern regions of the country, where the impact of the pandemic was more severe.

We use the new dataset of trade flows across 269 European regions in 24 countries constructed in Santamaría et al. (2020) to systematically explore for the first time trade patterns within and across country borders. We focus on the differences between home trade, country trade and foreign trade. We document the following facts: (i) European regional trade has a strong home and country bias, (ii) geographic distance and national borders are important determinants of regional trade, but cannot explain the strong regional home bias and (iii) the home bias is heterogeneous across regions and seems to be driven by political regional borders.

Lockdowns’ to control the spread of COVID-19 in the UK affected many aspects of life and may have adversely affected diets. We aimed to examine (1) the effect of lockdowns on fruit and vegetable consumption, as a proxy for healthy diets more generally, and on weight and well-being, (2) whether any subgroup was particularly affected and (3) the barriers and facilitators to a healthy diet in lockdown. We find no evidence for decreased fruit and vegetable consumption during lockdown compared with afterwards. If anything, consumption increased by half a portion daily among women, particularly among those who normally have a long commute. This finding, combined with a significant increase in physical activity, suggests that behaviours were healthier during lockdown, consistent with higher self-reported health. However, well-being deteriorated markedly, and participants reported being heavier during the lockdown as well. Our qualitative data suggest that an abundance of resources (more time) supported higher fruit and vegetable consumption during lockdown, despite increased access issues. Our results may assuage concerns that lockdowns adversely affected diets. They may point to the impact of commuting on diet, particularly for women. We add longitudinal evidence to a growing body of literature on the adverse effect of lockdown on mental health.

Falling off-grid solar prices and an expanding grid are revolutionizing choices for nearly a billion people without electricity. Using experimental price variation, we estimate demand for all electricity sources in Bihar, India, during a four-year period when electrification leapt from 27% to 64%. We find that: (i) household surplus from electrification increased five-fold; (ii) both solar and the grid boost electrification but households gain more surplus from the grid; (iii) grid investments and subsidies strongly reduce demand for off-grid solar. When we extend the model to eight African countries where grid infrastructure is weaker and subsidies lower we find that off-grid solar often provides higher surplus than the grid.

We propose a novel external-instrument SVAR procedure to identify and estimate the impulse response functions, regardless of the shock being invertible or recoverable. When the shock is recoverable, we also show how to estimate the unit variance shock and the ‘absolute’ response functions. When the shock is invertible, the method collapses to the standard proxy-SVAR procedure. We show how to test for recoverability and invertibility. We apply our techniques to a monetary policy VAR. It turns out that, using standard specifications, the monetary policy shock is not invertible, but is recoverable. When using our procedure, results are plausible even in a parsimonious specification, not including financial variables. Monetary policy has significant and sizeable effects on prices.

Does imagining what life could have been in the absence of a shock change current satisfaction? To answer this we collect field data through a survey that covers the period before, during and after the COVID-19 lockdown, exploiting the features of a natural experiment combined with induced variation stemming from a randomized control trial (RCT). Our data covers first year students studying before the COVID-19 pandemic, during the full COVID-19 lockdown period, and during the partial COVID-19 lockdown period. The RCT directs a subset of students to imagine how satisfied they could have been in the absence of COVID-19. The control group are instead asked about their current satisfaction. We find that imagining life in the absence of a shock (COVID-19) can impact current satisfaction : the higher individuals think their satisfaction would have been in the absence of the shock, the lower their current satisfaction. However, the natural experiment component of our study suggests that counterfactual reasoning may mislead. By comparing the satisfaction of COVID-19 students asked to imagine university life without COVID-19, with the reported satisfaction of equivalent students just before the arrival of COVID-19, we show students typically over-exaggerate how satisfied they would have been if a negative shock had not happened.

Do community networks shape firm-to-firm trade in emerging economies? We study the role of communities in facilitating firm-to-firm trade and firm outcomes using data on firm-to-firm transactions and firm owners’ community (castes) affiliations for the universe of medium- and large- sized firms in West Bengal, India. We find that firms are substantially more likely to trade, and trade more, with firms from their own caste. Studying the mechanisms underlying this effect, we find evidence consistent both with castes alleviating trade frictions and taste-based discrimination by firms against those outside their community. Guided by these stylized facts, we develop a model of firm- to- firm trade in which communities affect pair productivity and matching costs and estimate the model using our reduced-form estimates. A counterfactual extending the positive effects of castes on trade to all potential supplier-client pairs would increase the number of network links by 60% and increase average firm-to-firm sales by 20%.

Francis Fukuyama’s bold prediction that Western liberal democracy is ‘the final form of human government’ was promptly challenged by Samuel Huntington, who foresaw the future as a continuing clash of civilisations. This latter view has found support in the recent Beijing declaration by China and Russia of a ‘New World Order’ with distinct spheres of influence for different cultures. After discussing the contrast between such historical perspectives (of ‘immaculate convergence’ versus cultural diversity), we outline two accounts of how forms of governance emerge from competitive struggle ( either domestically or between nation states). However, to set the scene for applying these perspectives to current events, the paper begins with a summary of three eras of political economy post World War II - including the current ‘age of the strongman’, to use the terminology of Gideon Rachman. Subsequently, these various perspectives are employed to see what light they may throw on the disastrous turn of events following the Beijing declaration, with a focus on Russia, where the history of a powerful central state has played a crucial role. How enduring the Russian example may prove in the Darwinian struggle of cultural competition is, of course, a key issue for our time.

New technologies allow perfect detection of environmental violations at near-zero marginal cost, but take-up is low. We conducted a field experiment to evaluate enforcement of water conservation rules with smart meters in Fresno, CA. Households were randomly assigned combinations of enforcement method (automated or in-person inspections) and fines. Automated enforcement increased households’ punishment rates from 0.1 to 14%, decreased water use by 3%, and reduced violations by 17%, while higher fine levels had little effect. However, automated enforcement also increased customer complaints by 1,102%, ultimately causing its cancellation and highlighting that political considerations limit technological solutions to enforcement challenges.

We study the impact of commercial property taxation on vacancy rates and rents in the UK, using a new data-set, and exploiting exogenous variations in property tax rates from reliefs in the UK system: small business rate relief (SBRR), retail relief and empty property relief. We estimate that the retail relief reduces vacancies by 85%, and SBRR relief by up to 49%, while empty property exemption increases them by up to 89%. The effect of retail relief on clusters of urban properties (the "High St") is no different to its overall effect. SBRR increases (decreases) the likelihood that a property is occupied by a small (large) business. We also use data on asking prices for rental properties to study the effect of reliefs on rental rates. Rental rates move in the opposite direction to vacancy rates, except in the case of empty property relief. All these findings are consistent with a novel model of directed search in the commercial property market, also presented in the paper.

We exploit a data disclosure project by the Italian government (OpenCivitas) which allowed mayors to view each other’s detailed expenditure data through a dedicated website. We interpret views on the website as generating a directed network. Mayors in the network are on average younger, more educated, they are more likely to come from larger cities which more often are in the northern regions and are more likely to be affliated to traditional parties, although populist parties usually rely more on the web for communication and political activities. Using directed dyadic models we find that mayors tend to form links with mayors of similar age who manage similar-sized cities and most often in their same region. However, links are more likely to be formed when mayors don’t share the same gender, education and party affliation. Mayors in this network do not engage in yardstick competition with neighbouring municipalities while all the other mayors do, and rather compete with each other, despite the physical distance. We show that this network existed before the website opened, but we find that after data disclosure yardstick competition within the network becomes strongly driven by mayors who are up for re-election. This was not the case before data disclosure. For the other municipalities, yardstick competition between neighbours remains uncorrelated with mayors’ term limits.

Which households will be most affected by the energy price shock? How large are the energy, financial, and environmental benefits of improved energy efficiency of the British residential building stock? How do policies or interventions in price setting in energy markets affect these incentives? We develop a measurement and ex-ante modelling approach using granular property-level micro data representing around 50% of the English and Welsh building stock. This allows us to quantify the likely impact of recent energy price shocks on energy bills and how these bills would look like if energy savings measures were implemented. We find, on average, that the energy price shock acts as a form of progressive taxation hitting better-off regions more than poorer ones, in absolute terms. We estimate that on aggregate, 30% of energy consumption could be saved if buildings were upgraded to their highest energy efficiency standard. At market prices, these savings range between GBP 10 to 20 billion pounds per year with the highest energy savings largely concentrated in the wealthiest parts of the UK However, current policies weaken incentives for households to invest in energy efficiency upgrades. Current policies, such as the energy price cap, appears to be very regressive. Alternative, more targeted policies, are cheaper, easily implementable and could align incentives better.

This paper examines whether and to what extent publications of the Federal Open Market Committee (FOMC) minutes contain significant information for the expectation of future monetary policy in the US. We construct measure of new surprise series with intradaily data for the Fed futures contracts and the responses of stock markets, fixed income markets and exchange rates to these surprises during 2004–2017. We find that the release of FOMC minutes affects the market volatility and financial asset prices respond significantly to FOMC minutes announcements. Finally, volatility and the volume of reactions increase during the zero lower bound. Specifically, this research finds that the release of FOMC minutes induces “higher than normal” volatility and shows that financial markets respond quickly and significantly to the release of FOMC minutes.

This paper begins by listing three uncomfortable implications of the standard expected utility model of individual decision-making concerning participation in fiscal crimes : that tax evasion and benefit fraud can be treated identically; fiscal crimes should be endemic; and that all individuals, depending on parameter values, should be either honest or dishonest. Levitt and List’s (2007) utility function relating to decisions with a moral dimension is adapted to offer insight into these implications involving an individuals optimal honesty and moral hinterland. Predictions are developed that include moral costs as a determinant of dishonest intentions and are tested with reference to some 2,942 questionnaire responses to a 2016 national (UK) survey. This paper offers insight into the way moral costs inform perceptions of the intrinsic value of doing the right thing thereby providing a richer analysis of fiscal crimes. The account has particular relevance for policy prescriptions that involve aspects of shame.

We exploit the introduction of an open data online platform - part of a transparency program initiated by the Italian Government in late 2014 - as a natural experiment to analyse the effect of data disclosure on mayors’ expenditure and public good provision. First, we analyse the effect of the program by comparing municipalities on the border between ordinary and special regions, exploiting the fact that the latter regions did not participate in the program. We find that mayors in ordinary regions immediately change their behaviour after data disclosure by improving the disclosed indicators, and that the reaction depends also on their initial relative performance, a yardstick competition effect. Second, we investigate the effect of mayors’ attention to data disclosure within treated regions by tracking their daily accesses to the platform, which we instrument with the daily publication of newspaper articles mentioning the program. We find that mayors react to data disclosure by decreasing spending via a reduction of service provision, resulting in an aggregate decrease in efficiency. Overall, mayors seem to target variables that are disclosed on the website at the expense of variables that are less salient.

The loss of a keystone species can theoretically lead to large social costs because their complex ecosystem interactions may be important for environmental quality. We quantify these effects for the case of vultures in India where they play an important public health role by removing livestock carrion from the environment. The expiration of a patent for a common chemical painkiller led to its increased use in cattle, unexpectedly rendering carcasses fatal to vultures, leading to a catastrophic and near-total population collapse. Using habitat range maps for the affected species, we compare high to low vulture suitability districts before and after the patent for the painkiller expired. We find that, on average, all-cause death rates increased by more than 4% in vulture-suitable districts after the vultures nearly went extinct. We find suggestive evidence that feral dog populations and rabies increased, and that water quality deteriorated in the affected regions. These mechanisms are consistent with the loss of the scavenging function of the vultures. Quantifying the costs of biodiversity losses has critical implications for optimal investments into species conservation and rehabilitation.

We study the monetary- fiscal mix in the European Monetary Union. The medium and long-run effects of conventional and unconventional monetary policy are analysed by combining monetary policy shocks identified in a Structural VAR, and the general government budget constraint featuring a single central bank and multiple fiscal authorities. In response to a conventional easing of the policy rate, the cumulated response of the fiscal deficit is positive. Conversely, in response to an unconventional easing affecting the long end of the yield curve, the primary fiscal position barely moves. This is consistent with the long-run effect of unconventional monetary easing on the price index, which is about half that of conventional easing. The aggregate long-run cumulated surplus is mainly driven by Germany's fiscal policy during the period in which unconventional monetary policy was adopted.

Political donations in the UK have been subject to comprehensive disclosure since 2001. We study the data produced as part of this disclosure policy to evaluate the role of private and public political finance over time. Total political donations have grown by 250% since 2001, reaching over £100 million in real terms for the first time in 2019. This increase has been driven by donations from private individuals, who now account for approximately 60% of donations in election years compared to 40-50% up to the late 2010s. Furthermore, ‘superdonors’ (those contributing more than £100,000) have been a prominent driver of the rise, increasing their own share from approximately 36% in 2017 to 46% in 2019. We also show that private donations to Labour fell sharply in the final stages of Jeremy Corbyn’s leadership. Overall, these trends have benefited the Conservative Party, leading to an historic resource gap between the two main parties emerging circa 2019. We calculate that the ‘resource gap’ between parties now stands at approximately £27 million compared to an historic average of £8-10 million (even when taking account of publicly-funded ‘Short’ money provided to the Opposition).

This paper documents a longitudinal crisis of midlife among the inhabitants of rich nations. Yet middle-aged citizens in our data sets are close to their peak earnings, have typically experienced little or no illness, reside in some of the safest countries in the world, and live in the most prosperous era in human history. This is paradoxical and troubling. The finding is consistent, however, with the prediction -- one little-known to economists -- of Elliott Jaques (1965). Our analysis does not rest on elementary cross-sectional analysis. Instead the paper uses panel and through-time data on, in total, approximately 500,000 individuals. It checks that the key results are not due to cohort effects. Nor do we rely on simple life-satisfaction measures. The paper shows that there are approximately quadratic hill-shaped patterns in data on midlife suicide, sleeping problems, alcohol dependence, concentration difficulties, memory problems, intense job strain, disabling headaches, suicidal feelings, and extreme depression. We believe the seriousness of this societal problem has not been grasped by the affluent world’s policy-makers.

This paper examines the nexus between gender equality, climate change, and innovation at the firm level. Based on three hypotheses derived from a novel theoretical framework linking climate change and gender equality to within-firm innovation activities, we use a cross-section dataset of 87, 996 firms across 36 industries in 103 countries, surveyed across different waves during the 2010-2020 periods to implement an instrumental variable strategy and show that environmental policies unambiguously induce firm-level process and product innovation, through its influence on the endogenous bargaining power of women in society and firms. We document that female productivity has both a direct effect on innovation (0.1-1.3% increase in the likelihood of innovation) and an indirect effect (serving as the intermediation for the environment-innovation nexus). Contrarily, greenhouse gas emissions by themselves have an ambiguous effect on innovation. The type of greenhouse gas emissions and the measure of innovation both contribute to this ambiguity. Overall, our results show that it is not the physics of climate change that induces innovation but rather the countervailing human responses to policies that mitigate climate change that stimulate innovation.

Using administrative data on the globally connected super-rich in the UK, we study the effect of a large tax reform on migration behaviour. Prior to 2017, off shore investment returns for `non-doms' - individuals tax resident in the UK but with connections to other countries - were untaxed. Average off shore investment returns for these individuals exceeded £420,000; even without considering other types of income, this puts them in the top 0.2% of the population. A reform in 2017 brought long-stayers and UK-born non-doms into the standard tax system, reducing their effective net of average tax rate by between 8.8% and 13.0%. We nd that migration responses were limited : our central estimate of the migration elasticity is 0.02, and across a range of specifications we can rule out elasticities larger than 0.5. Using reforms for the UK-born super-rich who were living abroad, we find that migration elasticities are limited even for recent arrivals, for whom our central estimate is 0.18. Assuming similar elasticities for all non-doms, abolition of the preferential regime would increase tax revenue collected from non-doms by £3.2bn (84%).

A central challenge for social scientists consists in explaining why people vote and what are the consequences of their behaviour. Exploiting variation in national opinion polls across UK general elections, and in the degree of safeness of British constituencies over time, I provide evidence of a significant impact of pre-election polls on electoral outcomes and shed light on a novel mechanism. I find that opinion polls affect voters’ behaviour via their interaction with the recent electoral history of a constituency : first, turnout decreases when the polls predict non-competitive elections, and this effect is stronger in safe seats. Second, the composition of local vote shares and parties’ performance is also impacted by anticipated election closeness and the effects vary heterogeneously depending on whether polls predictions are aligned with the past electoral outcomes of a constituency. Finally, the causal impact on voters’ participation is confirmed with consistent individual-level evidence.

This paper examines the impact of foetal exposure to air pollution from agricultural fires on Brazilian students cognitive performance later in life. We rely on comparisons across children who were upwind and downwind of the fires while in utero to address concerns around sorting and temporary income shocks. Our findings show that agricultural fires increase P M2.5, resulting in significant negative effects on pupils’ scores in Portuguese and Maths in the 5th grade through prenatal exposure. Back-of-the-envelope calculations suggest that a 1% reduction in P M2.5 from agricultural burning has the potential to increase later life wages by 2.6%.

African Americans face shorter employment durations than similar whites. We hypothesize that employers discriminate in acquiring or acting on ability-relevant information. In our model, monitoring black but not white workers is self-sustaining. New black hires were more likely red by previous employers after monitoring. This reduces firms' beliefs about ability, incentivizing discriminatory monitoring. We confirm our predictions that layoffs are initially higher for black than non-black workers but that they converge with seniority and decline more with AFQT for black workers. Two additional predictions, lower lifetime incomes and longer unemployment durations for black workers, have known empirical support.

We investigate the importance of subjective expectations of returns to and effort costs of the two principal investments that mothers make in newborns : breastfeeding and stimulation. We find heterogeneity across mothers in expected effort costs and expected returns for outcomes in the cognitive, socio- emotional and health domains, and that this contributes to explaining heterogeneity in investments. We find no significant differences across women in preferences for child developmental outcomes. We simulate the impact of alternative policies on investments. Our findings highlight the relevance of interventions designed to address maternal depression and reduce perinatal fatigue alongside interventions that increase perceived returns to investments.

We study a nonlinear two-way fixed effects panel model that allows for unobserved individual heterogeneity in slopes (interacting with covariates) and (unknown) flexibly specified link function. The former is particularly relevant when the researcher is interested in the distributional causal effects of covariates, and the latter mitigates potential misspecification errors due to imposing a known link function. We show that the fixed effects parameters and the (nonparametrically specified) link function can be identified when both individual and time dimensions are large. We propose a novel iterative Gauss-Seidel estimation procedure that overcomes the practical challenge of dimensionality in the number of fixed effects when the dataset is large. We revisit two empirical studies in trade (Helpman et al., 2008) and innovation (Aghion et al., 2013), and find non-negligible unobserved dispersion in trade elasticity (across countries) and the effect of institutional ownership on innovation (across firms). These exercises emphasize the usefulness of our method in capturing flexible (and unobserved) heterogeneity in the causal relationship of interest that may have important implications for the subsequent policy analysis.

Persecution, pogroms, and genocide have plagued humanity for centuries, costing millions of lives and haunting survivors. Economists and economic historians have recently made new contributions to the understanding of these phenomena. We provide a novel conceptual framework which highlights the inter-relationship between the intensity of persecution and migration patterns across dozens of historical episodes. Using this framework as a lens, we survey the growing literature on the causes and consequences of persecution, pogroms, and genocide. Finally, we discuss gaps in the literature and take several tentative steps towards explaining the differences in survival rates of European Jews in the 20th century

This paper presents evidence on the short and long-term impact of the COVID-19 crisis on India’s rural youth. We interviewed about 2,000 vocational trainees from Bihar and Jharkhand three times after the first national lockdown in 2020, between June 2020 and December 2021. We find that a third of respondents who were in salaried jobs pre-lockdown lost their jobs, and half of those who worked out of state returned home shortly after the lockdown. We report a stark difference between men and women: while many male workers took up informal employment, most female workers dropped out of the labor force. In the second part of the paper, we use a randomised experiment to document the effects of a government-supported digital platform designed to provide jobs to low-skilled workers. The platform turned out to be difficult to use and publicised only a few job ads. We find no effect on job search intensity or employment. Our findings suggest that bridging the gap between rural young workers and urban formal labor markets requires more active and targeted policy interventions, especially for female workers

This paper studies the effect of the VAT threshold on firm growth in the UK, using exogenous variation over time in the threshold, combined with turnover bin fixed effects, for identification. We find robust evidence that annual growth in turnover slows by about 1 percentage point when firm turnover gets close to the threshold, and weaker evidence of higher growth when the threshold is passed. Growth in firm costs shows a similar pattern, indicating that the response to the threshold is likely to be a real response rather than an evasion response. Firms that habitually register even when their turnover is below the VAT threshold (voluntary registered firms) have growth that is unaffected by the threshold, whereas firms that select into the Flat-Rate Scheme have a less pronounced slowdown response than other firms. Similar patterns of turnover and cost growth around the threshold are also observed for non-incorporated businesses. Finally, simulation results clarify the relative contribution of "non-crossers" ( firms who eventually register for VAT) and "non-crossers" (those who permanently stay below the threshold) in explaining our empirical findings

he difficulty in resurrecting inter-ethnic cooperation in the aftermath of violence and genocide is one of the biggest challenges facing post-conflict societies. Using experimental data from post-genocide Rwanda and Burundi, this paper shows that an unwarranted tendency to blame others for negative outcomes is a behavioural barrier that makes reconciliation difficult. We show that individuals systematically (and mistakenly) blame accidental negative shocks (noise) to the deliberate intent of individuals (bias). This victimhood bias wherein individuals ascribe noise to bias is much larger for (a) individuals for whom ethnic identity is salient; (b) for those who have had greater exposure to inter-ethnic violence. Further, we observe that both inter-ethnic contact and economic development are associated with a decline in this victimhood bias. Finally, those with a lower victimhood bias are more likely to behave cooperatively in inter-ethnic relationships. Our results suggest that insurance agreements that limit negative shocks and reduce noise, can encourage reconciliation by mitigating feelings of victimhood.

We study the impact of a large-scale scientist recruitment program – China’s Junior Thousand Talents Plan (青年千人计划) – on the productivity of recruited scholars and their local peers in Chinese host universities. Using a comprehensive dataset of published scientific articles, we estimate effects on quantity and quality in a matched difference-in-differences framework. We observe neutral direct productivity effects for participants over a 6-year post-period: an initial drop is followed by a fully offsetting recovery. However, the program participants collaborate at higher rates with more junior China-based co-authors at their host institutions. Looking to peers in the hosting department, we observe positive and rising productivity impacts for peer scholars, equivalent to approximately 0.6 of a publication per peer scholar in the long-run. Heterogeneity analysis and the absence of correlated resource effects point to the peer effect being rooted in a knowledge spillover mechanism.

We conduct a field experiment to study whether concerns to preserve an anti-liberal self-image affect low cost, private school owners' willingness to explore a collaboration with a liberal Pakistani NGO. While explicitly revealing the NGO's liberal motivation to school owners has a significant impact on beliefs about the NGO's objectives, on average, we find only limited evidence that treated school owners are less willing to explore a collaboration with our partner NGO. However, heterogeneous treatment effects suggest that differences in political identity cause negative reactions among the minority of school owners expressing conservative beliefs during a seemingly unrelated follow-up survey.

Gerard Roland examines data going back to 3,000 BC for historical roots that might explain the current division of nations as between cultures of collectivism and individualism. In response to the appeal for theories bearing on the empirical evidence presented - and of recent moves by Russia and China to create a New World Order based on similar cultural division - three contributions are discussed. First is the competing powers perspective of Acemoglu and Robinson, who propose that individualism flourishes where power is evenly balanced between the state and the people : otherwise, either Despotism or Disorder will ultimately prevail. Then there is Ken Binmores study of cooperative social contracts : this offers support for stable societies of each cultural type, based on the folk theorem of repeated games. Finally the notion that dictatorship may be sustained by deception rather than repression - by leaders whom Guriev and Treisman call spin dictators. In the light of these perspectives, what to make of the current drive for a new global order that recognizes different spheres of influence for each of Roland’s cultural types? We look specifically at the case of Russia.

How does import protection affect export performance? In trade models with scale economies, import liberalization can reduce industry-level exports by cutting domestic production. We show that this export destruction mechanism reduced US export growth following the permanent normalization of trade relations with China (PNTR). But there was also an offsetting boost to exports from lower input costs. We use our empirical results to calibrate the strength of scale economies in a quantitative trade model. Counterfactual analysis implies that while PNTR increased aggregate US exports relative to GDP, exports declined in the most exposed industries because of the export destruction effect. On aggregate, the US and China both gain from PNTR, but the gains are larger for China.

Despite the wide adoption of revenue management in many industries such as airline, railway, and hospitality, there is still scarce empirical evidence on the gains or losses of such strategies compared to uniform pricing or fully flexible strategies. We quantify such gains and losses and identify their underlying sources in the context of French railway transportation. The identification of demand is complicated by censoring and the absence of exogenous price variations. We develop an original identification strategy combining temporal variations in relative prices, consumers’ rationality and weak optimality conditions on the firm’s pricing strategy. Our results suggest similar or better performance of the actual revenue management compared to optimal uniform pricing, but also substantial losses of up to 16.2% compared to the optimal pricing strategy. We also highlight the key role of revenue management in acquiring information when demand is uncertain.

This paper examines how natural disasters affect low public nances and their interplay with intergovernmental transfers and external resources. We document the causal effect of a natural disaster on the allocation of local public resources the local government fiscal dynamics by exploiting the random nature of the 2013 Typhoon Haiyan, one of the most devastating natural disasters in recent history. Combining data on local government nance with reports on the level of damages caused by the typhoon, we employ several estimation strategies: we first rely on difference-in-differences and event study designs, and we further address a potential endogeneity concern by instrumenting the intensity exposure to the typhoon with distance to the storm path. We show that local revenue and public expenditures remain largely unaffected, except debt service, which are on average 15% lower in affected cities or municipalities. However, we document important heterogeneity in local revenue responses. We find no support for the moral hazard problem : our results indicate that external aid leads to higher local expenditures, particularly general public services, socioeconomic expenditures, including education and social services, and debt payments. These results highlight the crucial role of central government transfers in supporting local governments and mitigating the geographical economic disparities in the aftermath of exogenous shocks such as natural disasters.

Previous research has established that undergraduate students in the UK who had attended private schools perform less well at university, on average, than equivalent students who had been educated at a state school prior to university (Smith and Naylor, 2001 and 2005; Crawford, 2014a). This well-known result has provided an evidence base for the use of contextualised offers in admissions across the sector (Schwartz Report, 2004; Hubble and Bolton, 2020) as an instrument for enhancing social mobility. In the current paper, we use a rich dataset for a particular university to examine whether the negative association between private schooling and class of degree awarded holds across all students, independent of ethnicity: we find that it does not. For White students, we obtain the standard result that private schooling is associated negatively with class of degree. However, in stark contrast, among students whose ethnicity is self-reported as either Black, Asian or Mixed Ethnicity, attendance at a private school prior to university is, on average, associated positively with the class of degree awarded. On further exploration, we find this is driven by a strong positive association among Black students and students of Mixed Ethnicity; the overarching category of Black, Asian and Minority Ethnicity conceals substantive differences within the category. Among Asian students, the absence of any association between private schooling and degree class, on average, masks a very strong negative association for those from lower socioeconomic status backgrounds. We discuss and interpret our results in the context of hypotheses within the literatures on schooling effects and on the ethnicity awarding gap in higher education.

Over many centuries, church and state have grown together, and apart. Sometimes linked like Siamese twins, sometimes in conflict with each other. This chapter discusses the major themes in the literature on church and state, some of the findings in the political economy of religion, and evaluates emerging directions in research on church-state relations.

The pandemic was accompanied by a wave of adoption of remote work practices. This paper uses online job vacancy data to study how UK firms have adopted remote work. Overall, remote work increased by 300%. Our analysis finds little evidence that occupations have fundamentally changed to better accommodate remote work tasks, nor evidence of changes in the occupational composition of jobs. We find that the overall increase in remote working is driven by the increasing use of remote work at the firm level, especially among firms that were less likely to use remote work before the pandemic. This is consistent with changes in organisational practices or updated information about the viability of large-scale remote working.

This study quantifies the effects of macroeconomic variables on various market-based systemic-risk measures in 24 European banks over the 2008-2019 period. In a first step, I measure daily systemic risk for banks based on ∆CoVaR, MES, and SRISK frameworks, and examine the contributions of individual banks to aggregate systemic risk during specific stress events. Systemic risk in European banks has risen in the wake of the global financial crisis and the Brexit referendum result. In a second step, I investigate how macroeconomic conditions affect systemic risk in the short and long-run. I find that three systemic risk measures have a long-run stable relationship with EU industrial production, EU inflation, Euribor, and US equity market volatility, but some variables have opposite effects in the short and long-run.

This paper uses an instrumental variable approach based on close elections to evaluate the effect of political parties on local fiscal policy in England and Wales over the period 1998-2016. Our main finding is that political control of the council (by Labour, Conservative or Liberal Democrat parties) has no effect on total expenditure, the composition of expenditure, the property tax rate (council tax per band D property) or total council tax revenue. Thus, our results confirm the widely expressed belief that centrally imposed constraints on local government fiscal policy (rate-capping, and more recently, compulsory referenda) hold local government fiscal policy in a tight grip.

We investigate the lead-lag relationship between weekly sovereign bond yield changes and stock market returns for eight European countries, and how it changed during the period 2008-2018. We use a Markov-Switching Granger Causality method that determines reversals of causality endogenously. In all countries, there were often changes in the direction of the Granger causality between the two markets that coincided with global and idiosyncratic economic events. Stock returns led changes of sovereign bond yields in all countries, particularly during the financial and the Euro Area crisis. Changes of sovereign bond yields occasionally led stock returns in France, Spain and Portugal.

We develop an equilibrium model of the labor market to investigate the joint evolution of gender gaps in labor force participation and wages. We do this overall and by task-based occupation and skill, which allows us to study distributional effects. We structurally estimate the model using data from Mexico over a period during which women's participation increased by fty percent. We provide new evidence that male and female labor are closer substitutes in high-paying analytical task-intensive occupations than in lower-paying manual and routine task-intensive occupations. We find that demand trends favored women, especially college-educated women. Consistent with these results, we see a widening of the gender wage gap at the lower end of the distribution, alongside a narrowing at the top. On the supply side, we find that increased appliance availability was the key driver of increases in the participation of unskilled women, and fertility decline a key driver for skilled women. The growth of appliances acted to widen the gender wage gap and the decline of fertility to narrow it. We also trace equilibrium impacts of growth in college attainment, which was more rapid among women, and of emigration, which was dominated by unskilled men. Our counterfactual estimates demonstrate that ignoring the countervailing effects of equilibrium wage adjustments on labor supplies, as is commonly done in the literature, can be misleading.

Few topics attract such intense political debate as top tax rates : in the UK, this has led to two top income tax rate reforms since the financial crisis. Recently, the measurement of top incomes and wealth has also proved controversial, in both the UK and the US. The chapter by Delestre et al. (2022) examines both of these issues. It first studies the distribution of income in the UK, focusing on the income sources and demographics of those at the top, as well as non-taxable sources of income. It then describes the current taxation of top incomes, and suggests some directions for reform. Mirroring this structure, in this commentary we discuss first the measurement of financial inequalities, focusing on top income and wealth shares, and then the scope for policy reforms to tackle some of the issues raised, also focusing on the UK.

We construct novel data on female population shares by age, district, and religion in South Asia from 1881 to 1931. Sex ratios skew male in Northern India and are more balanced in Southern and Eastern India, including Burma. Male-biased sex ratios emerge most visibly after age 10, and this is not specific to any one region, religion, or time period. Sikhs have the most male-biased sex ratios, followed by Hindus, Muslims, and Jains. The female share correlates across religious groups within districts. Evidence that sex ratios correlate with suitability for wheat and rice is weaker than suggested by the existing literature.

Following previous work on consequentialist decision theory, we consider an unrestricted domain of finite decision trees, including continuation subtrees, with : (i) decision nodes where the decision maker must make a move ; (ii) chance nodes at which a “roulette lottery” with exogenously specified strictly positive probabilities is resolved ; (iii) event nodes at which a “horse lottery” is resolved. A complete family of binary conditional base preference relations over Anscombe–Aumann lottery consequences is defined to be “prerational” just in case there exists a behaviour rule that is defined throughout the tree domain which is explicable as avoiding, under all predictable circumstances, consequences that are regrettable given what is feasible. Prerationality is shown to hold if and only if all conditional base preference relations are complete and transitive, while also satisfying both the independence axiom of expected utility theory and a strict form of Anscombe and Aumann’s extension of Savage’s sure thing principle. Assuming that the base relations satisfy non-triviality and a generalized form of state independence that holds even when consequence domains are state dependent, prerationality combined with continuity on Marschak triangles is equivalent to representation by a refined subjective expected utility function that excludes zero probabilities.

How successful are sanctions at targeting the economic interests of political elites in affected countries? We study the case of Iran, using information on the stock exchange listed assets of two specific political entities with significant influence over the direction of Iran's nuclear program. Our identification strategy focuses on the process of negotiations for sanctions removal, examining which interests bene t most from news about diplomatic progress. The results indicate the `bluntness' of sanctions on Iran, but also provide evidence of their effectiveness in generating substantial economic incentives for
elite policymakers to negotiate a deal for sanctions relief.

This paper explores the implications of voter loss-aversion and imperfect recall for the dynamics of electoral competition in a simple Downsian model of repeated elections. We first establish a benchmark result: when the voters’ reference point is forward-looking, there are a continuum of rational expectations equilibria (REE). When voters are backward-looking i.e. the reference point is last period’s recalled policy, interesting dynamics only emerge when voters have imperfect recall about that policy. Then, the interplay between the median voter’s reference point and political parties’ choice of platforms generates a dynamic process of polarization (or de-polarization). Under the assumption that parties are risk-neutral, platforms monotonically converge over time to a long-run equilibrium, which is always a REE. When parties are risk-averse, dynamic incentives also come into play, and generally lead to more policy moderation, resulting in equilibria that are more moderate than the most moderate REE.

Lead exposure remains a significant threat to children’s health despite decades of policies aimed at getting the lead out of homes and neighborhoods. Generally, lead hazards are identified through inspections triggered by high blood lead levels (BLLs) in children. Yet, it is unclear how best to screen children for lead exposure to balance the costs of screening and the potential benefits of early detection, treatment, and lead hazard removal. While some states require universal screening, others employ a targeted approach, but no regime achieves 100% compliance. We estimate the extent and geographic distribution of undetected lead poisoning in Illinois. We then compare the estimated detection rate of a universal screening program to the current targeted screening policy under different compliance levels. To do so, we link 2010-2016 Illinois lead test records to 2010-2014 birth records, demographics, and housing data. We train a random forest classifier that predicts the likelihood a child has a BLL above 5µg/dL. We estimate that 10,613 untested children had a BLL≥5µg/dL in addition to the 18,115 detected cases. Due to the unequal spatial distribution of lead hazards, 60% of these undetected cases should have been screened under the current policy, suggesting limited benefits from universal screening.

Forced displacement as a consequence of wars, civil conflicts, or natural disasters does not only have contemporaneous consequences but also long- run repercussions. This eclectic overview summarizes some recent research on forced displacement in economic history. While many of the episodes covered refer to Europe, this survey points to literature across all continents. It highlights new developments, and points to gaps in the literature.

We estimate the short-run and longer-term effects of gifted children programs (GCP) in high schools in Israel. The program tracks the most talented students into gifted children classes, starting 10th grade. They receive more resources in smaller classes, a unique curriculum, access to high-quality teachers, and courses in universities. We use test scores in exams that measure cognitive achievements or intelligence and ability, measured in different ages, to select a comparison group of equally gifted students from other cities where GCP was not offered at the time. Based on administrative data, we follow 22 cohorts of GCP participants who graduated high school in 1992-2013. We measure treatment effects on outcomes, ranging from high school to the labor market in their 30s and 40s. Remarkably, the results we obtain do not vary when using alternative measures of ability or in the age, they are assessed. The evidence on the impact of GCP on academic achievements in high school is mixed, some compulsory subjects are affected negatively, and fewer are affected positively. However, these estimates are very small, implying a tiny effect size. These results stand in contrast to the abundance of educational resources enjoyed by GCP participants, in addition to better peers in terms of SES background and outcomes. We discuss in this context the objective of the program to widen the scope and area of interest of its participants beyond the regular curriculum. We also highlight the potential adverse effect of the Big-Fish-Little Pond Effect. In the longer run, we find meaningful positive effects of GCP on higher education attainment. All gifted children achieve a BA degree, but a much higher share of GCP participants graduate with a double major. The effect of getting a Ph.D. is also positive, driven by more Ph.D. degrees in Elite Universities. GCP participants study more math, computer, and physical sciences but engage less in engineering programs. The net effect on STEM degrees is, therefore, zero. However, a much higher share of GCP participants graduated with two STEM majors. This evidence, along with the significant effect on a double major, suggests that GCP enhances the impact of “multipotentiality,” which characterizes many gifted adolescents. We find no effect of GCP on employment and earnings. Nor do we find that they work more than other equally talented children in the various sectors of the knowledge economy: hi-tech manufacturing, hi-tech services, and academic institutions. Finally, we examine marriage and family formation patterns as mediating effects and find no discerned GCP effects. In the short-term, medium-run, and into adulthood, these comprehensive sets of results are not qualitatively different for females and males gifted children who participated in GCP. Treatment heterogeneity by giftedness level allows us to compare our results to earlier studies that used regression discontinuity designs to identify GCP effects on only marginally eligible students for such programs. We find meaningful differences in treatment effect between marginal and inframarginal gifted children, suggesting that it is essential to examine GCP’s impact over the whole spectrum of Giftedness. Importantly, we find that GCP similarly affects low and high-SES students. Half of the students among the six youngest cohorts in our sample started the program in middle school, while the others did that in high school. We find no differences in GCP effect on high school and university outcomes by the length of the program

This paper documents that the COVID-19 pandemic induced pressures on thehealth care system have significant adverse knock-on effects on the accessibility and quality of non-COVID-19 care. We observe persistently worsened performance and longer waiting times in A&E; drastically limited access to specialist care; notably delayed or inaccessible diagnostic services; acutely undermined access to and quality of cancer care. We find that providers under COVID-19 pressures experience notably more excess deaths among non-COVID related hospital episodes such as, for example, for treatment of heart attacks. We estimate there to be at least one such non-COVID-19 related excess death among patients being admitted to hospital for non-COVID-19 reasons for every 30 COVID-19 deaths that is caused by the disruption to the quality of care due to COVID-19. In total, this amounts to 4,003 non COVID-19 excess deaths from March 2020 to February 2021. Further, there are at least 32,189 missing cancer patients that should counterfactually have started receiving treatment which suggests continued increased numbers of excess deaths in the future due to delayed access to care in the past.

The decision of wholesalers to internalize retail order flow primarily reflects institutional liquidity demand. We first use the Tick Size Pilot to highlight this decision’s influence on the retail trade imbalances denoted Mroib by Boehmer et al. (2021). We then show that wholesalers internalize more retail order flow when institutional demand is higher, leading Mroib to be inversely related to institutional order flow. Intraday returns move in the same direction as institutional price pressure but the opposite direction of Mroib. Moreover, |Mroib| is highest when institutional trading costs are highest. Distant future returns display strong ∪-shaped patterns conditional on Mroib, consistent with a permanent liquidity premium driving the positive relation between these returns and the magnitude of |Mroib|.

This paper investigates the effect of electronic payments technology on firms' tax compliance in a large developing economy. We consider India's demonetization policy which, by limiting the availability of cash, led to a large increase in the use of electronic forms of payments. Using administrative data on firms' tax returns and variation in the strength of the demonetization shock across local areas, we find that greater use of electronic payments leads to firms reporting more sales to the tax authorities. This effect is strong enough to explain roughly half of the large (11%) increase in reported sales observed during demonetization.
