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,...

This paper analyzes the properties of runoff electoral systems when voters are strategic. A model of three-candidate runoff elections is presented, and two new features are included: the risk of upset victory in the second round is endogenous, and many types of runoff systems are considered....

A principal chooses between in-house production and outsourcing. An agent will be hired when production is in-house. An agent will be contracted upon when production is outsourced. In each case, the agent earns experience benefits: future monetary returns from managing production, reputation,...

This paper introduces endogenous credit constraints in a search model of unemployment. These constraints generate multiple equilibria supported by self-fulfilling beliefs. A stock market bubble exists through a positive feedback loop mechanism. The collapse of the bubble tightens the credit...

A health care provider chooses medical service quality and cost-reduction effort. Both choices are noncontractible. An insurer observes both quality and cost effort, and may credibly disclose them to consumers. In prospective payment, the insurer fully discloses care quality, and sets a...

This paper offers an ambiguity-based interpretation of variance premium - the differ- ence between risk-neutral and objective expectations of market return variance - as a com- pounding effect of both belief distortion and variance differential regarding the uncertain economic regimes. Our...
