摘要

Theorem 1 in Bhargava, Majumdar, and Sen (2015) provides a necessary condition for a social choice function to be locally robust ordinal Bayesian incentive compatible with respect to a belief system satisfying top-set correlation. In this paper, we provide a counterexample to that theorem and consequently provide a new necessary condition for the same in terms of sequential ordinal nondomination.
