Goeree, Jacob K; Kushnir, Alexey (2011). On the Equivalence of Bayesian and Dominant Strategy Implementation in a General Class of Social Choice Problems. Working paper series / Department of Economics No. 21, University of Zurich.



We consider a standard social choice environment with linear utilities and independent, one-dimensional, private values. We provide a short and constructive proof that for any Bayesian incentive compatible mechanism there exists an equivalent dominant strategy incentive compatible mechanism that delivers the same interim expected utilities for all agents. We demonstrate the usefulness and applicability of our approach with several examples. Finally, we show that the equivalence between Bayesian and dominant strategy implementation breaks down when utilities are non-linear or when values are interdependent, multi-dimensional, or correlated.
