Dominant Strategy Implementation in Economic Environments

Dominant strategy implementation in economic environments

We study dominant strategy implementation especially in economic environments. Wefirst show that in general environments, strategy-proofness and quasi-strong-non-bossiness together are necessary and sufficient for dominant strategy implementation via the associated direct revelationmechanism. Wenext prove that in weak separable environments, strategy-proofness is sufficient for dominant strateg...

Almost-dominant Strategy Implementation

Though some economic environments provide allocation rules that are implementable in dominant strategies (strategy-proof), a significant number of environments yield impossibility results. On the other hand, while there are quite general possibility results regarding implementation in Nash or Bayesian equilibrium, these equilibrium concepts make strong assumptions about the knowledge that playe...

On Sufficiency of Dominant Strategy Implementation in Environments with Correlated Types

We show that for any mechanism there exists an equivalent dominant strategy incentive compatible mechanism for social choice environments with correlated types when agent’s matrix of conditional probabilities satisfies the full rank condition. JEL classifications: D82
