A well—known result from the theory of finitely repeated games statesthat if the stage game has a unique equilibrium, then there is a uniquesubgame perfect equilibrium in the finitely repeated game in which theequilibrium of the stage game is being played in every period. Here Ishow that this...

It is well known that the rock-paper-scissors game has no pure saddle point. Weshow that this holds more generally: A symmetric two-player zero-sum game hasa pure saddle point if and only if it is not a generalized rock-paper-scissors game.Moreover, we show that every finite symmetric...

We show that for many classes of symmetric two-player games, the simple decision rule \imitate-the-best" can hardly be beaten by any other decision rule. Weprovide necessary and sufficient conditions for imitation to be unbeatable and showthat it can only be beaten by much in games that are of...

This paper considers the use of neural networks to model bounded rational behaviour. The underlying theory and use of neural networks is now a component of various forms of scientific enquiry, be it modelling artificial intelligence, developing better pattern recognition or solving complex...

This paper explores a model of bounded rationality in evolutionary game play in which agent choice is based on a social psychological process of categorization and social inference. The computer simulation of the model demonstrates that agents' increasing ability to categorize opponents in the...

Goeree & Holt (2001) observe that, for some parameter values, Nash equilibrium providesgood predictions for actual behaviour in experiments. For other payoff parameters, however,actual behaviour deviates consistently from that predicted by Nash equilibria. They attributethe robust deviations...

This paper considers the ‘negotiation game’ (Busch and Wen [4]) which combines the features of two-person alternating offers and repeated games. Despite the forces of bargaining, the negotiation game in general admits a large number of equilibria, some of which involve delay in agreement and...

We explore the consequences of the assumptions used in modern cryptographywhen applied to repeated games with public communication. Technically speaking, we model agents by polynomial Turing machinesand assume the existence of a trapdoor function. Under these conditions, we prove a Folk Theorem...

This paper uses the complexity of non-competitive behaviour to provide a new justification for competitive equilibrium in the context of extensive-form market games with a finite number of agents. This paper demonstrates that if rational agents have (at least at the margin) an aversion for...
