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...

We study a dynamic model of environmental protection in which the level of pollution is a state variable that strategically links policy making periods. Policymakers are forward looking but politically motivated: they have heterogeneous preferences and do not fully internalize the cost of...

This paper reviews the literature on governments' motivations for negotiating and joining international trade agreements. I discuss both normative explanations for trade agreements and explanations based on political-economy concerns. Most of the paper focuses on the purpose of multilateral...

This paper develops the empirical and theoretical case that differences in economic institutions are the fundamental cause of differences in economic development. We first document the empirical importance of institutions by focusing on two 'quasi-natural experiments' in history, the division of...

Do societies choose inefficient policies and institutions, in contrast to what would be suggested by a reasoning extending the Coase Theorem to politics? Do societies choose inefficient policies and institutions because of differences in the beliefs and ideologies of their peoples or leaders? Or...

We consider dynamic processes of coalition formation in which a principal bargains sequentially with a group of agents. This problem is at the core of a variety of applications in economics and politics, including a lobbyist seeking to pass a bill, an entrepreneur setting up a start-up, or a...

Allocation of resources in the local public sector involves economic and political forces. Spending for elementary and secondary education is a major area of public expenditure. In many states, the bulk of this spending is subject to referendum. In addition, grants-in-aid from state governments...

This paper discusses the two leading views of history and political institutions. For some scholars, institutions are mainly products of historical logic, while for others, accidents, leaders, and decisions have a significant impact. We argue that while there is clear evidence that history...

This paper studies the effects of progressive income taxes and education finance in a dynamic heterogeneous agent economy. Such redistributive policies entail distortions to labor supply and savings, but also serve as partial substitutes for missing credit and insurance markets. The resulting...
