An adversarial model of criminal trial is considered with three verdict choices--innocent, guilty of moderate crime, and guilty of serious crime. Depending on the parties' access to evidence and initial beliefs in the courtroom about the possible crimes, the judge may agree to the defendant's...

We introduce ex-ante collusion whereby the supervisor stops monitoring for a transfer payment from the agent, in addition to ex-post collusion following the monitoring outcome. Extending a well-known model of hierarchy, we study the determinants of ex-ante collusion and show that, depending on...

Evaders of any dues such as local council tax, motor vehicle tax, tv license fees, etc., if detected, can pay promptly the dues plus any fine or postpone, which usually means a larger fine, and potentially imprisonment if payments are not made in full. Dominant among the likely reasons for this...

I develop a model with endogenous gun ownership and study the interaction between the demands for guns by heterogeneous potential offenders and victims. I show that the interaction depends on pervasiveness of guns, injury probabilities and, in particular, the impact of the gun on the probability...

This article investigates signaling and screening roles of wage offers in a single-play matching model with two-sided unobservable characteristics. It generates the following predictions as matching equilibrium outcomes: (i) "good" jobs offer premia if "high-quality" worker population is large;...

We study private provision of a continuous public good in an incomplete information repeated game. The analysis generates the following predictions in the form of Perfect Bayesian equilibria. When the discount factor is low, the game played by increasingly optimistic players may collapse into a...

I study the first-round separating equilibrium of a buyer-seller bargaining game, extended to allow for asymmetric information, strategically delayed offers and offers restricted to a portion of the good. When bargaining is over a consumption good, in equilibrium the "strong" buyer uses a...

We consider a multi-stage game of fund-raising to study the announcement strategy of a fund-raiser, who is privately informed about the number of potential contributors, with the objective of collecting maximal contributions for a public project. We show that whether the public project is convex...
