We develop a theory of moral behavior, individual and collective, based on a general model of identity in which people care about "who they are" and infer their own values from past choices. The model sheds light on many empirical puzzles inconsistent with earlier approaches. Identity...

We analyze the value placed by rational agents on self-confidence, and the strategies employed in its pursuit. Confidence in one's abilities generally enhances motivation, making it a valuable asset for individuals with imperfect willpower. This demand for self-serving beliefs (which can also...

International surveys reveal wide differences between the views held in different countries concerning the causes of wealth or poverty and the extent to which people are responsible for their own fate. At the same time, social ethnographies and experiments by psychologists demonstrate...

This paper examines the often stated idea that the poor do not support high levels of redistribution because of the hope that they, or their offspring, may make it up the income ladder. This "prospect of upward mobility" (POUM) hypothesis is shown to be fully compatible with rational...

This paper shows how the optimal financial structure of a firm complements incentive schemes to discipline managers, and how the securities' return streams determine the claimholders' incentives to intervene in management. The theory rationalizes (1) the multiplicity of securities, (2) the...

This paper analyzes the organization of the R&D activity in an incomplete contract framework. It provides theoretical foundations to understand how the allocation of property rights on innovations may affect both the frequency and the magnitude of these innovations; to rationalize commonly...

This paper argues that parties regulate competition among like-minded factions so as to enhance reputation building by, and voter trust in, the politicians standing for a given cause. While intra- and interparty competition contributes to keeping politicians on their toes, unbridled competition...

The paper develops an agency-theoretic approach to interest-group politics and shows the following: (1) the organizational response to the possibility of regulatory agency politics is to reduce the stakes interest groups have in regulation; (2) the threat of producer protection leads to...

What is the best way to reward innovation? While prizes avoid deadweight loss, intellectual property (IP) selects high social surplus projects. Optimal innovation policy thus trades off the ex ante screening benefit and the ex post distortion. It solves a multidimensional screening problem in...
