We consider a dynamic auction environment with a long-lived seller and short-lived buyers mediated by a third party. A mediator has incomplete information about traders' values and selects an auction mechanism to maximize her expected revenue. We characterize mediator-optimal mechanisms and show...

We consider mechanisms for allocating a common-value prize between two players in an incomplete information setting. In this setting, each player receives an independent private signal about the prize value. The signals are from a discrete distribution and the value is increasing in both...

We develop a model of contests on networks. Each player is “connected” to a set of contests and exerts a single effort to increase the probability of winning each contest to which she is connected. We characterize equilibria under the Tullock contest success function and explore how behavior...
