Abstract:
We investigate the impact of ambiguous information structure on the quality of collective decision-making, given different voting rules and non-standard Bayesian updating methods. We also study the effects of embedding ambiguous information to static, finite games of incomplete information with unmediated communication. We intend to characterize the solution concept of sequential equilibria of cheap talk extensions under ambiguity. In addition, we want to test the set of equilibrium outcomes of such a game in experiments.
