The authors model entry incentives in auctions with risk-neutral bidders and characterize a symmetric equilibrium in which the number of entrants is stochastic. The presence of too many potential bidders raises coordination costs that detract from welfare. The authors show that the seller and...

We experimentally test an endogenous-timing investment model in which subjects privately observe their cost of investing and a signal correlated with the common investment return. Subjects overinvest, relative to Nash. We separately consider whether subjects draw inferences, in hindsight, and...

An experiment analyzing behavior in English common value auctions is reported. English auctions raise more revenue than first-price auctions only when bidders do not suffer from a strong winner's curse. Agents employ other bidders' dropout prices along with their private information as Nash...

This paper synthesizes findings from an ongoing research program on learning in signaling games. The present paper focuses on crossgame learning (the ability of subjects to take what has been learned in one game and generalize it to related games), an issue that has been ignored in most of the...
