چکیده
We develop a model of games with awareness that allows for di erential levels of awareness. We show that, for the standard modal logical interpretations of belief and awareness, a player cannot believe there exist propositions of which he is unaware. Nevertheless, we argue that a boundedly rational individual may regard the possibility that there exist propositions of which she is unaware as being supported by inductive reasoning, based on past experience and consideration of the limited awareness of others. In this paper, we provide a formal representation of inductive reasoning in the context of a dynamic game with awareness. We show that, given di erential awareness over time and between players, individuals can derive inductive support for propositions expressing their own unawareness. JEL Classi cation: D80, D82

Inductive reasoning about unawareness
We develop a model of games with awareness that allows for differential levels of awareness. We show that, for the standard modal-logical interpretations of belief and awareness, a player cannot believe there exist propositions of which he is unaware. Nevertheless, we argue that a boundedly rational individual may regard the possibility that there exist propositions of which she is unaware as b...

متن کاملSubjective Reasoning – Games with Unawareness
The subjective framework for reasoning is extended to incorporate the representation of unawareness in games. Both unawareness of actions and decision makers are modeled as well as reasoning about others’ unawareness. It is shown that a small grain of uncertainty about unawareness with rational decision makers can lead to cooperation in the finitely repeated prisoner’s dilemma. JEL Classificati...

متن کاملA Note on Unawareness
Modica and Rustichini 1994] provided a logic for reasoning about knowledge where agents may be unaware of certain propositions. However, their original approach had the unpleasant property that nontrivial unawareness was incompatible with partitional information structures. More recently, Modica and Rustichini 1999] have provided an approach that allows for nontrivial unawareness in parti-tiona...
