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.
Our activities
PEPE Research Group Seminar
Thursday: 11.15am-12.30pm
A weekly seminar is organised that brings top economists and political scientist speakers every week for a double-feature seminar in coordination with the LSE.

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: Learning in investment markets. https://arxiv.org/pdf/2502.08597
Abstract: We analyze the performance of heterogeneous learning agents in asset markets with stochastic payoffs. Our main focus is on comparing Bayesian learners and no-regret learners who compete in markets and identifying the conditions under which each approach is more effective. Surprisingly, we find that low regret is not sufficient for survival: an agent can have regret as low as O(log T) but still vanish when competing against a Bayesian with a finite prior and any positive prior probability on the correct model. On the other hand, we show that Bayesian learning is fragile, while no-regret learning requires less knowledge of the environment and is therefore more robust. Motivated by the strengths and weaknesses of both approaches, we propose a balanced strategy for utilizing Bayesian updates that improves robustness and adaptability to distribution shifts, providing a step toward a best-of-both-worlds learning approach. The method is general, efficient, and easy to implement. Finally, we formally establish the relationship between the notions of survival and market dominance studied in economics and the framework of regret minimization, thus bridging these theories. More broadly, our work contributes to the understanding of dynamics with heterogeneous types of learning agents and their impact on markets.
