When a strategic situation arises repeatedly, the possibility arises that equilibrium predictions can be justified by a dynamic adjustment process. We examine myopic adjustment dynamics, a class that includes replicator dynamics from evolutionary game theory, simple models of imitation, models...

In general, the result of the elimination of weakly dominated strategies depends on order. We find a condition, satisfied by the normal form of any generic extensive form, and by some important games which do not admit generic extensive forms, under which any two games resulting from the...

It has been argues that the natural notion of independence for conditional probability systems is weaker than sequential equilibrium's consistency condition. Kohlberg and Reny(1992) provide an attractive extra condition on a conditioal probability system thatimplies equivalence to consistency....

We consider an auction in which k identical objects of unknown value are auctioned off to n bidders. The k highest bidders get an object and pay the k+1st bid. Bidders receive a signal that provides information about the value of the object. We characterize the unique symmetric equilibirum of...

We consider discriminatory auctions for multiple identical units of a good. Players have private values, possibly for multiple units. None of the usual assumptions about symmetry of players' distributions over values or of their equilibrium play are made. Because of this, equilibria will...

This paper uses results of lattice theory, convex analysis, and nonsmooth analysis to establish conditions for the existence of pure-strategy Nash equilibria when payoff functions are continuous but not quasi-concave. A class of economic games for which this theory is important is given.

We consider the dynamic private provision of funds to a project that generates a flow of public benefits. Examples include fund drives for public television or university buildings. The games we study have complete information about payoffs, allow each player to contribute each period, and let...
