This paper considers a global game with ambiguity-averse players, where the variance of noise terms in private signals may be unknown, and it presents a laboratory experiment to test comparative statics results with respect to information quality. Suppose that one of the actions is a safe action...

This paper generalizes the concept of Sequential Equilibrium to allow for ambiguous incomplete information about types or states. We characterize conditions that ensure existence of Sequential Equilibria under ambiguous incomplete information. Under these conditions players form subjective prior...
