Implicit contracts can mitigate moral hazard in labor, credit and product markets. The enforcement mechanism underlying an implicit contract is the threat of exclusion: the agent fears that he will lose future income if the principal breaks off the relationship. This threat may be very weak in...

We derive the optimal contract between a principal and a liquidity-constrained agent in a stochastically repeated environment. The contract comprises a court-enforceable explicit bonus rule and an implicit fixed salary promise that must be self-enforcing. Since the agent's rent increases with...

This paper considers the optimal level of firm-specific training by taking into account the positive effect of training on the expected duration of workers current employment. In the framework of an efficiency wage model, a short expected job tenure represents a disamenity that reduces the...

This paper documents the role of unemployment and earnings risk in reconciling evidence in payoff differentials between self-employment and paid-employment. Using Spanish administrative data, we characterize the distribution and dynamics of earnings and document lower and less dispersed earnings...

Effective organizations are able not only to coordinate their members on efficient strategies but also to adapt members' strategies to unforeseen change in an efficient manner. We explore whether part of organizational culture - namely, relational contracts that facilitate both coordination and...

Using hand-collected data spanning more than a decade on European banks' sovereign debt portfolios, we show that the trust of residents of a bank's countries of operation in the residents of a potential target country of investment has a positive, statistically significant, and economically...

Corporate success stories often resemble a snowball. We show how initial luck in hiring talented people, the resulting technological advantage, superior corporate culture, and statusseeking by workers and by consumers can make small initial differences generate large differences over time.

This paper explores how the introduction of an experience rated system of unemployment insurance affects employment and welfare in a model where implicit contracts between firms and workers give rise to wage rigidities and unemployment. In the literature, it has been argued that experience rated...

We study the optimal duration of contracts in a principal-agent framework with both moral hazard and adverse selection. Agents decide on a contract-specific and non-verifiable investment. Incentive compatibility requires that initial contracts, which serve to screen the ability of newly hired...
