We argue that when externalities such as pollution are nonexcludable, agents must be compelled to participate in a “mechanism” to ensure a Pareto-efficient outcome. We survey some of the main findings of the mechanism-design (implementation-theory) literature – such as the Nash...

Court decisions in the past twenty years such as Southern Burlington County NAACP v. Mount Laurel Associated, as well as recent legislation, have made exclusionary zoning laws based on race illegal and have limited, at least in many states, the legality of exclusionary zoning based on income....

In the paper the trade-offs among endogenous transaction costs caused by two-sided moral hazard, exogenous monitoring cost, and economies of specialization are specified in a Grossman, Hart, and Moore (GHM) model to absorb Maskin and Tirole's recent critique and Holmstrom and Milgrom's criticism...

I analyze a model in which a principal offers a contract to an agent and can influence the agent's marginal return of effort by the choice of the project mission. The principal's and the agents' mission preferences are misaligned, and the agents have unobservable intrinsic motivation levels. I...

Optimal contracts between a buyer and a seller who trade multiple goods under asymmetric information are considered. The seller makes sequences of unobservable investments, and then realizes the value of the goods. The investment level and value of goods are private information for the seller...

We study the economic consequences of opportunities for dishonesty in an environment where efficiency relevant behaviour is not contractible, but rather incentivized by informal agreements in an ongoing relationship. We document the repeated interaction between a principal and an agent who,...

Delegated contracting describes a widely observable agency mode where a top principal, who has no direct access to a productive downstream agent, hires an intermediary to forward a sub-contract with specified output targets and payments. The principal makes the payment to the intermediary...

I analyze a model in which a principal offers a contract to an agent and can influence the agent’s marginal return of effort by the choice of the project mission. The principal's and the agents' mission preferences are misaligned, and the agents have unobservable intrinsic motivation levels. I...

Firms in decentralized markets often trade using quantity contracts, agreements that specify quantity in advance of trade. We show that firms use quantity contracts to reduce the costs of trading frictions. Specifically, quantity contracts are valuable for two reasons. First, they increase trade...

Empirical evidence shows that workers care about the mission of their job in addition to their wage. This suggests that employers can use the job mission to incentivize and screen their workers. I analyze a model in which a principal selects one agent to develop a project and influences the...
