CWIP - Kenichi NagasawaS2.79 via MS TeamsThe title of talk is "Treatment effect estimation with noisy conditioning variables" and the abstract can be found below. In this paper, I develop a new identification strategy for treatment effects when proxy variables for unobserved confounding factors are available. I use proxy variables to construct a random variable conditional on which treatment variables become exogenous. The key idea is that, under appropriate conditions, there exists a one-to-one mapping between the distribution of unobserved confounding factors and the distribution of proxies. To ensure sufficient variation in the constructed control variable, I use an additional variable, termed excluded variable, which satisfies certain exclusion restrictions and relevance conditions. I establish asymptotic distributional results for flexible parametric and nonparametric estimators of the average structural function. I illustrate empirical relevance and usefulness of my results by extending the identification strategy of Dale and Krueger (2002, QJE). |

Applied Economics, Econometrics & Public Policy (CAGE) Seminar - Guilherme Lichand (Zurich)S2.79Title: The Intertemporal Effects of Seeing Prices: Evidence from Garbled Offers in Malawi (with Maite Deambrosi and Jiajing Feng) ABSTRACT: Preventive health care products are often sold at heavily discounted prices in developing countries. Does that hurt future demand for these products, by inducing subjects to anchor on low prices? Previous research on discounts for anti-malaria bed nets (Dupas, Ecma 2014) documents that experience and learning effects brought about by discounts dominate anchoring effects (if any). Bed nets are, however, an experience good sold at low frequency. Many essential preventive health care products – such as chlorine – are credence goods and have to be purchased at much higher frequency. Moreover, if discounts were perceived as a bargain by study participants, higher future demand might not generalize outside of the experiment. In a field experiment in Malawi, we investigate whether discounts generate anchoring and transaction utility effects across different types of preventive health care products. We do so by cross-randomizing actual discounts and implicit deals. Concretely, we decompose transaction prices into a sticker price and a randomly assigned delivery fee – revealed regardless of the purchasing decision. We find that demand decreases with discounts but increases with the size of the implicit deal. Such intertemporal effects of seeing prices are consistent with anchoring and transaction utility effects. Anchoring decays with time, but lasts up to 2 months after seeing prices. Using impulse-response functions, we simulate counterfactual demand under different pricing policies, showing that universal discounts are dominated by targeted (garbled) offers to those most responsive to each instrument. |

CRETA Theory Seminar - Nima HaghpanahS2.79Title: A Cooperative Theory of Market Segmentation by Consumers Abstract: We consider a market that may be segmented and is served by a single seller. The surplus of each consumer in a segment depends on the price that the seller optimally charges, and this optimal price depends on the set of consumers in that segment. This gives rise to a novel cooperative game between consumers that determines market segmentation. We study several solution concepts. The most demanding solution concept, the core, requires that there is no objection to the segmentation by a coalition of consumers who benefit by forming a new segment. We show that the core is empty except for trivial cases. We then introduce a new solution concept, stability. A segmentation is stable if for each possible objection by a coalition, there is a counter-objection by a coalition in the original segmentation. We characterize stable segmentations as ones that are efficient and ``saturated,'' which means that the segments are maximal in some sense. We use this characterization to constructively show that stable segmentations exist. Even though stable segmentations are efficient, they need not maximize average consumer surplus, and segmentations that maximize average consumer surplus need not be stable. Our weakest solution concept, fragmentation-proofness, rules out objections by coalitions that include consumers from more than one segment. We show that a segmentation is fragmentation-proof if and only if it is efficient. This is joint work with Ron Siegel. |

Applied Economics, Econometrics & Public Policy (CAGE) Seminar - Anne Brockmeyer (Institute for Fiscal Studies)S2.79Title: Tax Audits Under Weak Fiscal Capacity: Experimental Evidence from Senegal, joint work with Pierre Bachas, Alipio Ferreira, and Bassirou Sarr. Abstract: Developing economies are characterized by limited compliance with government regulations, such as taxation. Resources for enforcement are scarce and audit cases are often selected in a discretionary manner. We study whether the increasing availability of digitized data helps improve audit targeting. In a field experiment at scale in Senegal, we compare tax audits selected by inspectors to audits selected by a risk-scoring algorithm. We find that inspector-selected audits are more likely to be conducted and uncover similar amounts of evasion as algorithm-selected audits. However, algorithm-selected audits require less manpower, are faster and may generate less corruption. In ongoing work, we attempt to unpack the algorithm’s (dis)functioning and its interaction with human capital. Seminar organisers: Manuel Bagues & Ludovica Gazze |

CRETA Theory Seminar - Jacopo PeregoS2.79Title: The Value of Data Records (with Simone Galperti & Aleksandr Levkun) Abstract: Many online platforms intermediate trade between sellers and buyers using data records of the buyers' personal characteristics. How much value do such intermediaries derive from each record? Is this value higher for specific buyers? What are its properties? We find that an important component of the value of a data record is a novel externality that arises when a platform pools records to withhold information from the sellers. Ignoring this externality can significantly bias our understanding of the value of data records. We then characterize a platform's willingness to pay for more data, thereby establishing a series of basic properties of the demand side of data markets. Our analysis combines modern information design with classic duality methods and applies to a large class of principal-agent problems. |

CWIP (CAGE Work in Progress) - Amrita KulkaS1.50 via MS TeamsLong-Run Agglomeration: Evidence from County Seat Wars
Urban areas are shaped by their size, perhaps particularly so over the long run. We study how historical shocks to the size of towns in the American West affected long-run economic outcomes, using elections which determined county seats (capitals) in the 1800s and a regression discontinuity (RD) design. High rates of mobility in the frontier period meant that these elections quintupled population density in winning locations, ultimately determining where 15% of a county resides today. Although the county seat provides relatively few government jobs, we show that the increased town size reshaped their modern local economies in several important ways. First, reported IRS income increases with an elasticity of 0.15 with respect to density. Second, these gains are distributed primarily to the upper end of the income distribution, leading to a 2.9pp increase in the top 5% income share. Finally, spillover effects onto nearby communities are minimal, cutting against notions of positive amenity provision and negative agglomeration shadows. |
