We consider an endogenous growth model in which appropriate organization fosters innovation, but because of contractibility problems, this benefit cannot be internalized. The organizational design element we focus on is the division of labor, which as Adam Smith argued, facilitates invention by...

We propose a model that combines statistical discrimination and educational sorting that explains why blacks get more education than do whites of similar cognitive ability. Our model explains the di¤erence between blacks and whites in the relations between education and AFQT and between wages...

How does the spatial distribution of employment opportunities influence residential location? We revisit this classic question in urban economics by exploiting a natural experiment generated by the history of state capitals. Many state employees in capital cities work in centrally located...

For generations of scholars and observers, the "transportation revolution," especially the railroad, has loomed large as a dominant factor in the settlement and development of the United States in the nineteenth century. There has, however, been considerable debate as to whether transportation...

We study the interaction between a public sector and a private sector in the provision of a private good. Under a limited budget, the public supplier uses a rationing policy. A private ?rm may supply the good to those consumers who are rationed by the public system. Consumers have di¤erent...

We extend implementation theory by allowing the social choice function to depend on more than just the prole of preferences of the agents and by allowing agents to support their statements with hard evidence. We show that a simple condition on the evidence structure which is necessary for the...

This paper gives identification and estimation results for marginal effects in nonlinear panel models. We find that linear fixed effects estimators are not consistent, due in part to marginal effects not being identified. We derive bounds for marginal effects and show that they can tighten...

We show that small switching costs can have surprisingly dramatic effects in infinitely repeated games if these costs are large relative to payoffs in a single period. This shows that the results in Lipman and Wang [2000] do have analogs in the case of infinitely repeated games. We also discuss...

“My own behavior baffles me. For I find myself not doing what I really want to do but doing what I really loathe.” Saint Paul What behavior can be explained using the hypothesis that the agent faces temptation but is otherwise a “standard rational agent”? In earlier work,...
