This paper shows that models where preferences of individuals depend not only on their allocations, but also on the well-being of other persons, can produce both large and testable effects. We study the allocation of workers with heterogeneous productivities to firms. We show that even small...

We develop a test for adverse selection and use it to examine private health insurance markets. In contrast to earlier papers that consider a purely private system or a system in which private insurance supplements a public system, we focus our attention on a system where privately funded health...

This paper studies a model of announcements by a privately informed government about the future state of the economic activity in an economy subject to recurrent shocks and with distortions due to income taxation. Although transparent communication would ex ante be desirable, we find that even a...

This paper formalizes in a fully-rational model the popular idea that politicians perceive an electoral cost in adopting costly reforms with future benefits and reconciles it with the evidence that reformist governments are not punished by voters. To do so, it proposes a model of elections where...

We study the optimal mechanism for downsizing the public sector which takes into account different informational constraints (complete versus asymmetric information on each workers efficiency) and political constraints (mandatory versus voluntary downsizing). Under complete information, the...

Obtaining information about changes in market conditions is vital for the survival of the firms operating in a changing environment. In this paper, we offer a theory of information flows in a setting in which the principal faces a project choice and needs to induce the agent, who is responsible...

This paper is the first to present empirical evidence consistent with models of signaling through unemployment and to uncover a new stylized fact using the 1988-2006 DWS, namely that, among white-collar workers, post-displacement earnings fall less rapidly with unemployment spells for layoffs...

I study the optimal project choice when the principal relies on the agent in charge of production for project evaluation. The principal has to choose between a safe project generating a fixed revenue and a risky project generating an uncertain revenue. The agent has private information about the...

We study a situation in which an auctioneer wishes to sell an object to one of N risk-neutral bidders with heterogeneous preferences. The auctioneer does not know bidders' preferences but has private information about the characteristics of the object, and must decide how much information to...

This paper formalizes in a fully-rational model the popular idea that politicians perceive an electoral cost in adopting costly reforms with future benets and reconciles it with the evidence that reformist governments are not punished by voters. To do so, it proposes a model of elections where...
