Applying unawareness belief structures introduced in Heifetz, Meier, and Schipper (2013a), we develop Bayesian games … with unawareness, define equilibrium, and prove existence. We show how equilibria are extended naturally from lower to … higher awareness levels and restricted from higher to lower awareness levels. We apply Bayesian games with unawareness to …

Equilibrium notions for games with unawareness in the literature cannot be interpreted as steady-states of a learning … process because players may discover novel actions during play. In this sense, many games with unawareness are "self … state there is an extensive-form game with unawareness that together with the players' play determines the transition to …

Intuitively, we expect that players who are allowed to engage in costless communication before playing a game would be … foolish to agree on an inefficient equilibrium. At the same time, however, such preplay communication has been suggested as a … communication among players leads to a Nash equilibrium (NE) of the action game. Within the set of NE, efficiency then turns out to …

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 … restricted from higher to lower awareness levels. We use our unawareness belief structure to show that the common prior …

The standard state-spaces of asymmetric information preclude non-trivial forms of unawareness (Modica and Rustichini …-trivial unawareness among several individuals, and which satisfies strong properties of knowledge as well as all the desiderata on … unawareness proposed this far in the literature. …

We generalize the ``No-speculative-trade" theorem for finite unawareness belief structures in Heifetz, Meier, and …

We prove a \no-speculative-trade" theorem under unawareness for the infinite case. This generalizes the result for the …

Heifetz, Meier and Schipper (2005) introduced a generalized state-space model that allows for non-trivial unawareness …

Case studies of cartels and recent theory suggest that repeated communication is key for stable cooperation in … environments where signals about others' actions are noisy. However, empirically the exact role of communication is not well … understood. We study cooperation under different monitoring and communication structures in the laboratory. Under all monitoring …
