"Implicit Contracts, incentive compatibility, and involuntary unemployment" (MacLeod and Malcomson, 1989) remains our most highly cited work. We briefly review the development of this paper and of our subsequent related work, and conclude with reflections on the future of relational contract...

We consider a labor market where the competitive search equilibrium is inefficient due to asymmetrical information. At the time when firms commit to specific hiring costs, workers hold private information on their intention of entering into retirement before the termination of the contract. When...

We provide a new rationale for the use of discretionary bonuses. In a setting with unknown match qualities between a worker and a firm and subjective evaluations by the principal, bonuses are useful in order to make the feedback from the firm to the workers credible. This way workers in good...

When groups face difficult problems, the voice of experts may be lost in the noise of others' contributions. We present results from a 'naturally noisy' setting, a large first-year undergraduate class, in which the 'expert's voice is lost' to such a degree that it is in fact optimal for all...

We investigate a competitive labor market with team production. Workers differ in their motivation to exert team effort and types are private information. We show that there can exist a separating equilibrium in which workers self-select into different firms and firms employing cooperative...

We investigate labor exchange teams in rural communities, which are prevalent in many developing countries. We show theoretically that these teams are beneficial to employers, who can outsource the monitoring of workers. Team members are incentivized to exert high effort because any deviation...

We characterize optimal incentive contracts in a moral hazard framework extended in two directions. First, after effort provision, the agent is free to leave and pursue some ex-post outside option. Second, the value of this outside option is increasing in effort, and hence endogenous. Optimal...

This study models producer protection legislation that would grant growers the right to claim damages (PPLD) if their contracts are prematurely terminated. In the absence of contracting frictions that prevent contractors from redesigning contracts to accommodate exogenous policy changes, PPLD...
