Because of its devastating effects in auctions and other mechanisms, collusion is prohibited andlegally prosecuted. Yet, colluders have always existed, and may continue to exist. We thus raise the followingquestion for mechanism design:What desiderata are achievable, and by what type of...

In unrestricted combinatorial auctions, we put forward a mechanism that guarantees a meaningful revenue benchmark based on the possibilistic beliefs that the players have about each other's valuations. In essence, the mechanism guarantees, within a factor of two, the maximum revenue that the...

Shimoji and Watson (1998) prove that a strategy of an extensive game is rationalizable in the sense of Pearce if and only if it survives the maximal elimination of conditionally dominated strategies. Briefly, this process iteratively eliminates conditionally dominated strategies according to a...

Three related trends in world politics – shifting in power relations, increased diversity of actors and entities, and the growing mobilization and politicization of global constituencies are contributing to a global “tussle” which threatens to erupt in a full-fledged international...
