This paper discusses the literature on the enforcement of incomplete contracts. It compares legal enforcement to enforcement via relationships and reputations. A number of mechanisms, such as the repeat purchase mechanism (Klein and Leffler (1981)) and efficiency wages (Shapiro and Stiglitz...

We relate the design of contract law to the process of development. In this paper, contract law defines which private agreements are enforceable (i.e. are binding and enforced by courts) and which are not. Specically, we consider an economy where agents face a hold-up problem (moral hazard in...

We formulate and solve the problem of optimal mechanism-design by a principal facing adverse selection and moral hazard from different sources. The parties' decision problem is comprised of a publicly observable collective choice and a partially private social choice. As in agency with pure...

Motivated by markets for ''expertise,'' we study a bandit model where a principal chooses between a safe and risky arm. A strategic agent controls the risky arm and privately knows whether its type is high or low. Irrespective of type, the agent wants to maximize duration of experimentation with...

We study relational contracting and renegotiation in environments with external enforcement of long-term contractual arrangements. An external, long-term contract governs the stage games the contracting parties will play in the future (depending on verifiable stage-game outcomes) until they...

"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...

I build a model of state verification by judges and study its consequences for contracting and welfare. I assume that judges have imperfect information about a state of nature and can use it selectively to implement their idiosyncratic/biased preferences. The interplay between judges' imperfect...
