If we express our knowledge in sentences, we will find that these sentences to some extent are linked by logical rules. We ask whether the structure logic imposes on our knowledge restricts what we forget and what we remember. The model is a two period S5-style modal logic. In this logic we...

This paper proposes a procedurally rational solution concept for two-person extensive-form games with complete information. The solution concept is based on the observation that the ex-post justifiability of choices is often a primary concern for decision-makers, especially in organizations. The...

In a self-confirming equilibrium, each player correctly forecasts the actions that opponents will take along the equilibrium path, but may be mistaken about the way that opponents would respond to deviations. This models a steady state of a learning process in which players observe actions...

We explore sequential voting in symmetric two-option environments. We show that the (informative) symmetric equilibria of the simultaneous voting game are also equilibria in any sequential voting structure. In unanimity games, (essentially) the whole set of equilibria is the same in all...

We extend Kohlberg and Mertens' (1986) structure theorem concerning the Nash equilibrium correspondence to show that its graph is not only homomorphic to the underlying space of games but that it is also unknotted. This is then shown to have some basic consequences for dynamics whose rest points...

The paper studies Bayesian Games which are extended by adding pre-play communication. Let T be a Bayesian game with three or more players. The main result is that if players can send private messages to each other and make public announcements then every communication equilibrium outcome, q,...
