Basel II changes risk management in banks strongly. Internal rating procedures would lead one to expect that banks are changing over to active risk control. But, if risk management is no longer a simple "game against nature", if all agents involved are active players then a shift from a...

This essay describes one economist's view of how Nash's work influenced the development of game theory as a tool for analyzing strategic behavior.

We characterize the open-loop and the Markov perfect Stackelberg equilibria for a differential game in which a cartel and a fringe extract a nonrenewable resource. Both agents have stock dependent costs. The comparison of initial market shares, across different equilibria, depends on which firm...

A linear-quadratic dynamic oligopoly model is developed and applied to the world coffee export market. The model nests various market structures using either open-loop or feedback strategies. The theoretical properties of this model are described. For given observed behavior, the assumption of...

The effect of risk aversion on Nash equilibrium trade restrictions is studied using numerical methods. An increase in a nation's level of risk aversion can lead to either an increase or decrease in its equilibrium restriction and either an increase or decrease in its rival's restriction. The...

We study games played between groups of players, where a given group decides which strategy it will play through a vote by its members. When groups consist of two voting players, our games can also be interpreted as network-formation games. In experiments on Stag Hunt games, we find a stark...

The canonical bargaining game in economics is the ultimatum game, played by tens of thousands of students around the world over the past three decades. In the ultimatum game, first studied by Werner Guth, Rolf Schmittberger, and Bernd Schwarze (1982), the “proposer” proposes how to split a...

A broad nontechnical coverage of many of the developments in game theory since the 1950s is given, together with some comments on important open problems and where some of the developments may take place. The reference section given serves only as a minimal guide to the many thousands of books...
