We compare the long-run effects of replacing unconditional transfers to the poor by transfers conditional on the education of children. Unlike Mirrlees' income taxation model, the distribution of skill evolves endogenously. Human capital accumulation follows the Freeman-Ljungqvist-Mookherjee-Ray...

A principal and an agent enter into a sequence of agreements. The principal faces an interim participation constraint at each date, but can commit to the current agreement; in contrast, the agent has the opportunity to renege on the current agreement. We study the time structure of agreement...

A model of "satisficing" behavior in the repeated Prisoners Dilemma is studied. Each player has an aspiration at each date, and takes an action. [S]he switches from the action played in the previous period only if the achieved payoff fell below the aspiration level (with a probability that...

This paper studies human capital investment in a spatial setting with interpersonal complementarities. A mixture of local and global social interactions affects the cost of acquiring education, and the return to human capital is determined endogenously in the market. We study how spatially...

This paper examines the impact of ethnic divisions on conflict. The analysis relies on a theoretical model of conflict (Esteban and Ray, 2010) in which equilibrium conflict is shown to be accurately described by a linear function of just three distributional indices of ethnic diversity: the Gini...

The textbook paradigm of economywide development rests on the premise of "balanced growth": that is, on the presumption that all sectors will grow in unison over time as a country gets richer. Of course, we would all agree that balanced growth is an abstraction. In many developing countries,...
