Abstract

Chakraborty and Harbaugh (2010) prove the existence of influential cheap talk equilibria in one sender one receiver games when the state is multidimensional and the preferences of the sender are state-independent. We show that only the babbling equilibrium survives the introduction of any small degree of uncertainty about the sender’s preferences in the spirit of Harsanyi (1973). None of the influential equilibria are robust to this kind of uncertainty.
