Locally robust implementation and its limits

Journal article: We study a notion of locally robust implementation that captures the idea that the planner may know agentsʼ beliefs well, but not perfectly. Locally robust implementation is a weaker concept than ex-post implementation, but we show that no regular allocation function is locally robust implementable in generic settings with quasi-linear utility, interdependent and bilinear values, and multi-dimensional payoff types.
