Two players simultaneously decide whether or not to acquire new weapons in an arms race game. Each player's type determines his propensity to arm. Types are private information, and are independently drawn from a continuous distribution. With probability close to one, the best outcome for each...

We consider a model where agents work in sequence on a project, share information not available to the principal, and can collude. Due to limited liability the Coase theormem does not apply. The distribution of surplus among the agents is there an important control variable for the principal,...

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 implementation...

We study the implementation problem for exchange economies when agents can renegotiate the outcome assigned by the planner and can collude. We focus on the use of sequential mechanisms and present a simple sufficient condition for implementation with renegotiation in strong perfect equilibrium....

It is well-known that, when agents in an organization possess private information that is unverifiable by an outside party, games where agents simply announce their information can have multiple equilibria that may impede the successful implementation of the organization's objectives. We show...

Psychological and experimental evidence, as well as a wealth of anecdotal examples, suggests that firms may confound fixed, sunk, and variable costs, leading to distorted pricing decisions. This article investigates the extent to which market forces and learning eventually eliminate these...

A principal must decide whether or not to implement a project which originated with one of her employees. The employees have private information about the quality of the project. A successfully implemented project raises the inventor's chance of promotion, at his peer's expense, but a failed...
