The swiftness and devastating impact of recent financial crises have taken many market participants by surprise, and pose challenges for economists seeking a theory of the onset of a crisis. We propose such a theory based on two features. The actions of diverse economic actors which undermine...

Many interactive environments can be represented as games, but they are so large and complex that individual players are in the dark about others' actions and the payoff structure.  This paper analyzes learning behavior in such 'black box' environments, where players' only source of information...

Individual behaviors such as smoking, fashion, and the adoption of new products is influenced by taking account of others' actions in one's decisions.  We study social influence in a heterogeneous population and analyze the long-run behavior of the dynamics.  We distinguish between cases in...

It is commonly asserted that such problems as inner-city traffic congestion and pollution can be understood as examples of the Prisoner`s Dilemma Game (PD), but there is a dearth of empirical research that tests this assertion. 587 car owners in Oxford City were presented with three pairs of...

During the Bretton Woods era, OECD countries grew at historically unprecedented rates. This Golden Age has many possible explanations, ranging from the return to liberal policies in international trade to a backlog of profitable growth opportunities after the neglect of the 1930s and war-time...

This paper studies games in which the players are not locked into their relationship for a fixed number of periods. We consider two-player games where player 1 can decide to let the opponent continue in the game or replace it with a new player. We also allow the possibility of player 2 quitting...

This paper models the indirect evolution of the preferences of a population of fully rational agents repeatedly matched to play a symmetric 2 x 2 game in biological fitnesses. Each agent is biased in favor of one of the strategies, and receives a noisy signal of his and his opponent`s bias. With...

Empirical evidence suggests that a Prime Minister can benefit from firing ministers who are involved in political scandals. We explore a model in which a minister`s exposure to scandals is positvely related to his policy activism, so that a Prime Minister may wish to protect him from resignation...

Evolutionary game theory has largely focused on finite games. Dynamic stability is harder to attain in infinite strategy spaces; Bomze (Monatshefte fur Mathematik 110, 1990, 189-206) and Oechssler and Riedel (Economic Theory 17, 2001, 141-162) provide conditions for the stability of rest points...

In this paper we examine how the quantity of information generated about firm prospects can be improved by splitting a firm’s cash flow into a ‘safe’ claim (debt) and a ‘risky’ claim (equity). The former, being relatively...
