How does imperfect contractibility of preferences influence the governance of a contractual relationship? We analyze a two-party decision-making problem where the optimal decision is unknown at the time of contracting. In consequence, instead of contracting on the decision directly, the parties...

Incentives often fail in inducing economic agents to engage in a desirable activity; implementability is restricted. What restricts implementability? When does re-organization help to overcome this restriction? This paper shows that any restriction of implementability is caused by an identifi...

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 paper presents a moral hazard model analyzing the agent's incentive to commit corporate crime. The principal can only observe profits which the agent can increase by committing crime or exerting effort. It is shown how different incentive contracts, i.e., thresholdlinear, capped bonus and...

Oliver Hart and Bengt Holmström were awarded the 2016 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for their fundamental contributions to contract theory. This article offers a short summary and discussion of their path breaking work.

The unilateral introduction of an emissions price can induce firms to relocate to other countries with less stringent environmental regulation. However, firms may be able to reduce the emissions costs in their home country by investing into low-carbon technologies or equipment (abatement...

This paper provides new analytical tools for studying principal-agent problems with adverse selection and limited commitment. By allowing the principal to use general communication devices we overcome the literature's common, but overly restrictive focus on one-shot, direct communication. In...

We develop a model of strategic contractual incompleteness that identifies conditions under which principals might omit even costlessly verifiable terms. We then use experiments to test comparative statics predictions of the model. While it is well known that verifiability imperfections can...

This paper analyzes a multitask Principal-Agent model in which the performance measures of some tasks are subjective and relational contract is needed for incentive provision. We find that rewarding the Agent based on a subjective measure that aggregates performance on multiple tasks can help...

Given a standard moral hazard problem, the agent's optimal compensation can be cast as a function of either (i) the gross outcome, or (ii) the net outcome, which is the gross outcome net of the agent's compensation. Contracts based on the net outcome are important in practice because (i)...
