This 1983 book is a wide-ranging study of the macroeconomic side of monetary theory. Traditional macroeconomics uses simple, aggregative models to analyse monetary and fiscal policy. Gale argues that we cannot do without it but also that it rarely attains the standards of rigour required of modern theory. This book can be seen as an attempt to do it properly. The early chapters are critical and reconstructive. They take a fresh look at standard topics such as wealth effects, money and (...) growth and the long-run effects of monetary and fiscal policy. Later chapters develop different themes. The questions raised are drawn from traditional macroeconomics but there are plenty of surprises. The conventional view is frequently turned on its head or shown to be unsatisfactory or not robust. This and other exciting ideas enliven a book which will continue to be of interest to students and theorists alike. (shrink)

The theory of competition has held a central place in economic analysis since Adam Smith. This book, written by one of the most distinguished of contemporary economic theorists, reports on a major research program to provide strategic foundations for the theory of perfect competition. Beginning with a concise survey of how the theory of competition has evolved, Gale makes extensive and rigorous use of dynamic matching and bargaining models to provide a more complete description of how a competitive equlibrium is (...) achieved. Whereas economists have made use of a macroscopic description of markets in which certain behavioral characteristics, such as price-taking behavior, are taken for granted, Gale uses game theory to re-evaluate this assumption, beginning with individual agents and modelling their strategic interaction. A strategic foundation for competitive equilibrium shows how such interaction leads to competitive, price-taking behavior. Essential reading for graduate courses in game theory and general equilibrium. (shrink)
