We use a simple graphical approach to represent Social Welfare Functions that satisfy Independence of Irrelevant Alternatives and Anonymity. This approach allows us to provide simple and illustrative proofs of May's Theorem, of variants of classic impossibility results, and of a recent result on...

The thesis of this paper is that more transparent, rule-bound and subtle mechanisms for policy coordination will be needed to ensure the success of an enlarged European Union. A common policy is a public good with distributional implications. Economists have developed a large number of plausible...

A group of agents wants to reform the status quo if and only if this is Pareto improving. Agents have private information and may have common or private objectives, which creates a tension between information aggregation and minority protection. We analyze a simple voting system - majority rule...

This paper shows how unilateral liberalization in one country can increase the voting support for reciprocal reduction in trade barriers in a partner country. When trade policies are determined simultaneously in the two countries, we show the possibility of multiple political equilibria -...

Theory offers differing perspectives and predictions about the impact of product market competition on corporate social responsibility (CSR). Using firm-level data on CSR from 2002 through 2015 and panel data on competition laws in 48 countries, we discover that intensifying competition induces...

We propose a new model of legislative bargaining in which coalitions have different values, reflecting the fact that the policies they can pursue are constrained by the identity of the coalition members. In the model, a formateur picks a coalition and negotiates for the allocation of the surplus...

The paper provides a comprehensive empirical analysis of majority rule and Tiebout sorting within a system of local jurisdictions. The idea behind the estimation procedure is to investigate whether observed levels of public expenditures satisfy necessary conditions implied by majority rule in a...

For voters with "social" preferences, the expected utility of voting is approximately independent of the size of the electorate, suggesting that rational voter turnouts can be substantial even in large elections. Less important elections are predicted to have lower turnout, but a feedback...

This paper presents a theoretical and empirical investigation of tax competition when voters use the tax policy of neighboring jurisdictions as information to evaluate the performance of their incumbent politicians. We show that this has implications both for voter tolerance of high taxes and...

We study the properties of the group-based model of voting in elections with more than two candidates. We consider two of the most widely used electoral rules around the world: plurality and majority runoff. We fully characterize the set of equilibria under both rules and identify the features...
