Political Economy and Public Economics
Political Economy and Public Economics
The Department of Economics at the University of Warwick has an active Political Economy and Public Economics (PEPE) Research Group. These two disciplines have natural complementarities. Political Economy focuses more on the political feasibility of certain policies by looking at which policies are more likely to enjoy public support and thus succeed in an electoral contest. Public economics looks more at determining which policies are optimal in every environment, but is less concerned about their political approval or feasibility.
Recent world events such as the public backlash against globalization and inequality have raised awareness for the need for more integration between these two approaches as political resistance to the adoption of potentially beneficial policies has become ever more salient. Hence by their very nature these two disciplines transcend traditional field divisions such as micro and macroeconomics: they use theoretical, empirical and experimental methods to obtain conclusions, thus generating synergies with various other groups in our department from development to experimental to history to macroeconomics to economic theory.

PEPE Research Group Annual Conference
In collaboration with colleagues from Princeton and Yale, and with the support of CEPR, the PEPE Research Group organises an annual conference which has become a central meeting of political economists in Europe. Having taken place in previous years in Venice and Rome, it attracts over 70 delegates attending from leading institutions in the US, EU and the UK. Every year, several of our PhD students get to participate in a fully funded conference with an opportunity to engage with leading scholars.
Find out more about this year's conference which will take place 26-27 April 2024 in Rome.
Organisers: Helios Herrera, Mateusz Stalinski

Title: Obfuscation in Competitive Markets (with Keyu Wu)
Abstract: In many markets, firms increase product complexity through add-on features, which can make the evaluation and comparison of products difficult and thus increase buyers' search cost. Does this product obfuscation limit buyers' search behavior and induce them to buy overpriced products? And if so, why does competition not eliminate obfuscated products? We show - based on competitive experimental markets - that if add-ons merely complicate the products without generating additional surplus, obfuscation via product complexity indeed becomes fragile because buyers display an aversion against complex products. However, in the presence of surplus-enhancing add-ons, obfuscation via product complexity becomes a stable market feature that severely constrains the depth and breadth of buyers' search. Sellers anticipate and take advantage of this by hiding unattractive product features and selling add-ons persistently above marginal cost. Even the most favourably priced product in the market is offered above marginal cost, and buyers persistently fail to find the best product such that inferior products have a good chance of being bought, leading to enduring price dispersion. Surplus-enhancing obfuscation opportunities are the causal driver of persistent profits and price dispersion because if we remove these opportunities, overall prices quickly converge to marginal cost.
