Two players bargain over the allocation of a sum of money. They are only incompletely informed about the opponent's alternative in case of conflict. The paper investigates two different experimental approaches: the spontaneous behavior of subjects in a game playing experiment and the strategies...

We define a generalized state-space model with interactive unawareness and probabilistic beliefs. Such models are desirable for many potential applications of asymmetric unawareness. We develop Bayesian games with unawareness, define equilibrium, and prove existence. We show how equilibria are...

Numerous laboratory experiments show that workers reciprocate to high wages with high effort, when there is perfect information on the surplus created. Recent field experiments, however, suggest that trust and reciprocity may be lower or absent when the information is incomplete. We report a...
