Treats key elements of price theory for second-year students of microeconomics, and presents a distinctive perspective on this material, embedding these elements in a sustained analytical argument linking price theory to the study of industry. This perspective is useful for second- and third-year economics and business students. Stresses the interdependence between output and employment decisions, focuses on E. H. Chamberlin's analysis of monopolistic competition, and emphasizes the implications of time and uncertainty. An appendix offers commentary on the way mathematics is employed at various steps in the main text. Distributed by St. Martin's Press. Annotation c. by Book News, Inc., Portland, Or.
