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...

This paper examines the role of asymmetry in all-pay auctions. In particular, this paper decomposes a change in players' valuations into the absolute change and the relative change, and analyzes how these changes a¢çect total expenditures. An increase in the sum of players' valuations...

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 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 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...
