We modify the dynamic pivot mechanism of Bergemann and VAalimAaki (Econometrica, 2010) in such a way that lump-sum fees are collected from the players. We show that the modi?ed mechanism satis?es ex-ante budget balance as well as ex-post e¡¾ciency, periodic ex-post incentive compatibility, and...

We characterize the structure of optimal assignment rules when both allocative inefficiency and expenditure inefficiency (e.g., rent-seeking) are present. We find that the optimal structure critically depends on how the hazard rate of the value distribution behaves, and that it is often optimal...

We characterize the optimal structure of prizes in contests, when the contest designer is interested in the maximization of either the expected total e¢çort or the expected highest e¢çort. The all-pay auction framework in the present paper makes it possible to derive all the results in Benny...

We present a framework to evaluate the impact of digital music distribution. We set up a representative model that enables the comparative static analysis. We then interpret two empirical observations about the music industry, the sales decline and the price constancy, and fit the model to these...

We study the effect of limited observability on the possibility of cooperation in a simple overlapping generations model. If new entrants can observe only the recent history of the game, then cooperation cannot be sustained for certain classes of games. (Copyright: Elsevier)

We characterize the structure of optimal assignment rules when both allocative ineffciency and expenditure ineffciency are present. We find that the optimal structure critically depends on how the hazard rate of the value distribution behaves, and that it is often optimal to use probabilistic...

This paper shows that the quality scores in sponsored search auctions can be optimally chosen to extract all the advertisers' surplus. The reason for the full extraction result is that the quality scores may effectively set all the bidders' valuations equal to the highest valuation, which...

We study the effect of asynchronous choice structure on the possibility of cooperation in repeated strategic situations. We model the strategic situations as asynchronously repeated games, and define two notions of effective minimax value. We show that the order of players’ moves generally...
