Classical location theory is extended from its least cost approach to a maximum profit framework in this outstanding collection of Melvin L. Greenhut's key essays. This extension of classical location theory changes the analysis used in location economics from that of pure competition to oligopolistic competition. Using the analysis which is developed in this volume, locational interdependencies and, in turn, industrial location are shown to be affected by, diverse factors, including among others, marginal cost curves, demand curves and the number of firms in the market. Employing empirical findings to relate theory to practice, the author establishes a general theory via which he investigates and resolves specific issues and problems.These essays make a major contribution by enabling the reader to appreciate the important developments that have taken place over recent years in location economics. Location Economics and its companion volume, Spatial Microeconomics, will be welcomed by students, teachers and practitioners of economics for improving access to Professor Greenhut's many important essays and papers.
