We explore sequential voting in symmetric two-option environments. We show that the (informative) symmetric equilibria of the simultaneous voting game are also equilibria in any sequential voting structure. In unanimity games, (essentially) the whole set of equilibria is the same in all...

We consider discrete versions of independent, private-value, first-price auctions. We show for any fixed finite set of possible bids, if the number of participants is large enough, then the set of rationalizable bids involves all players bidding the highest bid that is lower than their private...

In a self-confirming equilibrium, each player correctly forecasts the actions that opponents will take along the equilibrium path, but may be mistaken about the way that opponents would respond to deviations. This models a steady state of a learning process in which players observe actions...

The new decade has been called "the age of information." We show that, although information has become more accessible, the increase in the variety of products has made consumers' choices complex and uncertain. Faced with uncertainty about products' attributes offered by "umbrella brands,"...

n this paper we investigate the implementation problem arising when some of the players are ``faulty" in the sense that they fail to act optimally. The exact number and identity of the faulty players is unknown to the planner and to the nonfaulty players, but it is common knowledge that there...

This paper is the Schwartz Memorial Lecture, delivered at Kellogg, Northwestern University in May 1998. The lecture introduces some ideas about the possible use of tools taken from the economics literature to explain language phenomena. Two specific issues are discussed: From the domain of...

This paper presents an empirical study of spatial competition and a methodological approach to estimating product characteristics and consumer preferences in industries with products whose characteristics are unobservable or difficult to measure.We demonstrate the effective use of panel data on...
