During the 1980s, economic theory has been revolutionised by game theory. The game theory approach is now very widely used throughout the profession and has become a major tool for the construction of new economic models. It is the basic tool in the construction of a modern theory of industrial organisation and it has led to important developments in finance, labour economics and international trade. This major new collection - prepared by a leading international authority - is oriented towards researchers, professors and graduate students who are interested in the interface between game theory and economic theory. They include the seminal and most important recent papers on the development and application of game theory in economics.
