Predation occurs when a firm offers consumers favorable deals, usually in the short run, that get rid of competition and thereby harm consumers in the long run. Modern economic theory has shown how commitment or collective-action problems among consumers can lead to such paradoxical effects.But...

We consider a problem in which a buyer has private information about the efficient scale or nature of a relationship-specific investment by a producer. We show that reducing the producer's ex post bargaining power may enhance efficiency by providing incentives for the buyer to reveal his private...

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...

A long-standing conjecture is that winner-take-all games such as patent races lead to the survival of risk-takers and the extinction of risk-averters. In many species a winner-take-all game determines the males' right to reproduce, and the same argument suggests that males will evolve to be...
