【Titile】: Mixed strategy implementation under ambiguity

【Abstract】: This paper introduces mixed strategies into the implementation theory under ambiguity. An ambiguity averse player may strictly prefer a mixed strategy to any pure strategy. The introduction of mixed strategies allows us to strengthen and generalize previous results in de Castro and Yannelis (2018) and de Castro et al. (2017). We recast Prescott and Townsend (1984) with ambiguity averse players, and show that ambiguity aversion makes any efficient allocation incentive compatible. Furthermore, we show that every interim maxmin efficient allocation is mixed maxmin incentive compatible and also implementable in mixed strategies under the Wald type maxmin preferences. It follows from our new implementation results that ex-ante maxmin efficient allocations and interim private (information) maxmin value allocations are all mixed maxmin incentive compatible and implementable in mixed strategies under the Wald type maxmin preferences.
