Previous research has established that the predictions made by game theory about strategic behavior in incomplete information games are quite sensitive to the assumptions made about the players’ infinite hierarchies of beliefs. We evaluate the severity of this robustness problem by...

This paper provides a unified approach to equilibrium analysis in models for competing mechanisms (e.g., Szentes (2009), Yamashita (2010)), which may differ in terms of delegation of action choice, announcement of mechanisms, observability of messages, and equilibrium notions

We provide a complete answer regarding what social choice functions can be rationalizably implemented.

The theory of full implementation has been criticized for using integer/modulo games which admit no equilibrium (Jackson (1992)). To address the critique, we revisit the classical Nash implementation problem due to Maskin (1977, 1999) but allow for the use of lotteries and monetary transfers as...
