This paper studies the aggregate economic effects of diversity policies such as affirmative action in college admission. If agents are constrained in the side payments they can make, the free market allocation displays excessive segregation relative to the first-best. Affirmative action policies...

Mobility depends essentially on investment, which often occurs in environments in which individuals match (school) or will match after investing (the labor market). Where partners can transfer surplus to each other only imperfectly (NTU), the pattern of matching will typically be inefficient,...

Institutions affect prospects for economic growth and development. In this paper a condition on the primitives determines whether an economy supports markets. Agents differ in land holdings, skill, and power. A competitive market assigns land efficiently to the skilled, not necessarily to the...

This paper argues that foreign direct investment in economies with credit market imperfections may increase their vulnerability to capital flow shocks. Due to better access to financial markets foreign firms can use different wage contracts than domestic ones. This alters the domestic wage...

We study an assignment-with-investment model to highlight a tradeoff between investment in human capital before (ex ante system) and after (ex post system) matching on the labor market. The ex post system is better at coordinating investment within firms whereas the ex ante system is better at...

Economic institutions determine prospects for growth and development. This paper examines necessary conditions for an economy to support institutions that implement markets. Agents differ in land holdings, skill, and power. A competitive market assigns land to the skilled, not necessarily to the...
