We characterize full implementation of social choice sets in mixedstrategy Bayesian equilibrium. Our results concern … both exact and virtual mixed implementation. For exact implementation, we identify a strengthening of Bayesian monotonicity …, mixed Bayesian implementation is equivalent to mixed Bayesian monotonicity, incentive compatibility and closure. For …

This paper proposes the solution concept of interim correlated rationalizability, and shows that all types that have …

for some arbitrarily close type. Hence, refinements of rationalizability are not robust. This negative result is obtained … rationalizability when arbitrary common knowledge assumptions are relaxed (i.e., without assuming richness). For arbitrary spaces of …

We consider robust virtual implementation, where robustness is the requirement that implementation succeed in all type … robust virtual implementation in iteratively undominated strategies by means of incentive compatibility and measurability …
