This paper examines the difference between strategic ambiguity as in game theory and
ambiguity arising in individual decisions. We identify a new, non-strategic component …

We study incomplete information games with ambiguity averse players. Our focus is on
equilibrium concepts satisfying sequential optimality—each player's strategy is optimal at …

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 …

We adopt the epistemic framework of Battigalli and Siniscalchi (1999) to model the
distinction between a player's behavior at each node, which is part of the external state, and …

We consider an ambiguity averse, sophisticated decision maker facing a recurrent decision
problem where information is generated endogenously. In this context, we study self …

We study the properties of Dutch auctions in an independent private value setting, where
bidders face uncertainty over the type distribution of their opponents and evaluate their …

The standard extensive-form partitional representation of information in sequential games
fails to distinguish the description of the rules of interaction from the description of players' …

This paper proposes a model of how biased individuals update beliefs in the presence of
informational ambiguity. Individuals are ambiguous about the actual signal-generating …

This paper explores multi-stage incomplete information games with common ambiguous
information about states or types and ambiguity averse players. We characterize a belief …

We analyze the infinite repetition with imperfect feedback of a simultaneous or sequential
game, assuming that players are strategically sophisticated—but impatient—expected-utility …
