This paper studies Pareto e.cient income taxation in an economy with infinitely-lived individuals whose income generating abilities evolve according to a two-state Markov process. The study yields two main results. First, when individuals are risk neutral, the fraction of individuals who face a...

This paper considers the problem of pet overpopulation. It develops a tractable dynamic model whose positive predictions square well with key features of the current U.S. market for pets. The model is used to understand, from a welfare economic perspective, the sense in which there is...

This paper provides a welfare economic analysis of the problem of districting. In the context of a simple micro-founded model intended to capture the salient features of U.S. politics, it studies how a social planner should allocate citizens of different ideologies across districts to maximize...

This paper contrasts direct election with political appointment of regulators. When regulators are appointed, regulatory policy becomes bundled with other policy issues for which the appointing politicians are responsible. Since regulatory issues are not salient for most voters, regulatory...

This paper analyzes the economic role and performance of a type of financial insti- tution which is observed world-wide - rotating savings and credit associations (Roscas). Using a model in which individuals save for an indivisible durable consumption good, we study Roscas which distribute funds...

A key question concerning affirmative action is whether the labor-market gains it brings to minorities can continue without it becoming a permanent fixture in the labor market. The authors argue that this depends on how the policy affects employers' beliefs about the productivity of minority...
