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...

"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...

This paper studies the effect bargaining power has on self-enforcing contracts. Optimal contracts are characterized under three enforcement regimes. When enforcement is absent, I show that as the agent's bargaining power increases, her incentive payments decrease even though her total...

The term “liberty of contract” is usually associated with the doctrine that the due process clause of the United States Constitution prohibits or should prohibit the State from regulating contracts between private individuals. Many libertarians and free-market advocates embrace the liberty...

Principal-agent models usually invoke the strong assumption that the parties know ex ante for sure whether a variable is verifiable or not. In this paper we assume that only the probability of verification is known, and that this probability is endogenously determined. We analyze a...

In three experiments, we examine how an employer reputation system disciplines an online labor market (Amazon Mechanical Turk) in which employers may decline to pay workers while keeping their work product. These three experiments test the value of the employer reputation system for workers,...
