We investigate the effect of absence of common knowledge on the outcomes of coordination games in a laboratory experiment. Using cognitive types, we can explain coordination failure in pure coordination games while differentiating between coordination failure due to first- and higher-order...

A common feature of the literature on the evolution of preferencesis that evolution favors nonmaterialistic preferences only if preferencetypes are observable at least to some degree. We argue that this resultis due to the assumption that in each state of the evolutionary dynam-ics some Bayesian...

The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia....

A product set of pure strategies is a prep set ("prep" is short for "preparation") if it contains at least one best reply to any consistent belief that a player may have about the strategic behavior of his opponents. Minimal prep sets are shown to exists in a class of strategic games satisfying...

We analyze games of incomplete information and offer equilibrium predictions which are valid for, and in this sense robust to, all possible private information structures that the agents may have. We completely characterize the set of Bayes correlated equilibria in a class of games with...

We define a notion of correlated equilibrium for games with incomplete information in a general setting with finite players, finite actions, and finite states, which we call Bayes correlated equilibrium. The set of Bayes correlated equilibria of a fixed incomplete information game equals the set...

We analyze games of incomplete information and offer equilibrium predictions which are valid for all possible private information structures that the agents may have. Our characterization of these robust predictions relies on an epistemic result which establishes a relationship between the set...

We examine subjects’ behavior in sender-receiver games where there are gains from trade and alignment of interests in one of the two states. We elicit subjects’ beliefs, risk and other-regarding preferences. Our design also allows us to examine the behavior of subjects in both roles, to...

We compare communication about private information to communication about actions in a one-shot 2-person public good game with private information.The informed player, who knows the exact return from contributing and whose contribution is unobserved, can send a message about the return or her...
