We discuss the goals and means of positive decision theory and the implications for how to do decision theory. We argue that the goal of positive economic theory generally is to provide predictions and understanding and that representation theorems and other results of decision theory should be...

A principal allocates an object to one of I agents. Each agent values receiving the object and has private information regarding the value to the principal of giving it to him. There are no monetary transfers, but the principal can check an agent's information at a cost. A favored-agent...

We define and analyze a "strategic topology'' on types in the Harsanyi-Mertens-Zamir universal type space, where two types are close if their strategic behavior is similar in all strategic situations. For a fixed game and action define the distance between a pair of types as the difference...

This paper proposes the solution concept of interim correlated rationalizability, and shows that all types that have the same hierarchies of beliefs have the same set of interim-correlated-rationalizable outcomes. This solution concept characterizes common certainty of rationality in the...

"My own behaviour baffles me. For I find myself not doing what I really want to do but doing what I really loathe." Saint PaulWhat behaviour can be explained using the hypothesis that the agent faces temptation but is otherwise a "standard rational agent"?

We study the random Strotz model, a version of the Strotz (1955) model with uncer- tainty about the nature of the temptation that will strike. We show that the random Strotz representation is unique and characterize a comparative notion of \more temp- tation averse." Also, we demonstrate an...
