چکیده

We introduce and study a unified reasoning process which allows to represent the beliefs of both a fully rational agent and an unaware one. This reasoning process endows introspection and unawareness with natural properties. The corresponding model for the rational or boundedly rational agents is easy both to describe and to work with, and the agent’s full system of beliefs has natural descriptions using a reduced number of parameters.

Subjective 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...

A 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...

Introspection and Projection in Reasoning about Other Agents Introspection and Projection in Reasoning about Other Agents

This paper develops the formal aspects of a new apporach to reasoning about the knowledge of other agents. It is based on the principles of introspection, by which an agent is aware of the inferences he makes, and projection, by which an agent assumes that other agents have the same inference abilities as himself. The paper develops a logic that incorporates these principles and proves the soun...

Inductive Reasoning about Unawareness Inductive Reasoning about Unawareness

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 be...
