Tirole (1982) is commonly interpreted as proving that bubbles are impossible with finitely many rational traders with common priors. We study a simple variation of his model in which bubbles can occur, even though traders have common priors and even though it is common knowledge that the asset...

This paper studies the ability of interested parities to communicate private information credibly to a decision maker in settings where their payoffs depend on the decision maker's action, but not on their own information per se. Examples of such situations arise in advertising, corporate...

The purpose of this paper is to provided a simple model in which limited rationality endogenously generates incomplete contracts. I model limited rationality as in Lipman [1991,1992], focusing on the idea that boundedly rational agents do not necessarily know every implication of their...

This paper surveys some recent attempts to formulate a plausible and tractable model of bounded rationality. I focus in particular on models which view bounded rationality as stemming from limited information processing. I discuss computability, partitional models (such as automata, perceptrons,...

It has long been recognized that solving the logical omniscience problem requires using some kind of nonstandard possible worlds. While many such logics have been proposed, none has an obvious claim as the "right" logic to use to describe the reasoning of agents who are not logically omniscient....
