This state-of-the-art collection of papers on the theory of Cournotian competition focuses on two main subjects: oligopolistic Cournot competition and contests. The contributors present various applications of the Cournotian Equilibrium Theory, addressing topics such as equilibrium existence and uniqueness, equilibrium structure, dynamic processes, coalitional behavior and welfare. Special emphasis is placed on the aggregative nature of the games that are relevant to such theory. This contributed volume was written to celebrate the 80th birthday of Prof. Koji Okuguchi, a pioneer in oligopoly theory.

James Friedman provides a thorough survey of oligopoly theory using numerical examples and careful verbal explanations to make the ideas clear and accessible. While the earlier ideas of Cournot, Hotelling, and Chamberlin are presented, the larger part of the book is devoted to the modern work on oligopoly that has resulted from the application of dynamic techniques and game theory to this area of economics. The book begins with static oligopoly theory. Cournot's model and its more recent elaborations are covered in the first substantive chapter. Then the Chamberlinian analysis of product differentiation, spatial competition, and characteristics space is set out. The subsequent chapters on modern work deal with reaction functions, advertising, oligopoly with capital, entry, and oligopoly using noncooperative game theory. A large bibliography is provided.

This up-to-date synthesis of the basic tools and survey results in international trade theory is unique in giving factor mobility equal billing with goods trade, highlighting factor flows in the context of a mainstream approach to trade theory. The importance of the international flow of factors has grown in recent decades, primarily because of increasing returns, imperfect competition, multinational corporations, and labor migration; theories of factor mobility and trade in goods can no longer be lumped together. Using sophisticated techniques, as well as simple economic intuitions and easy-to-follow diagrams, Kar-yiu Wong systematically presents within unified frameworks all the basic analytical techniques involved in the theories of international trade and factor mobility. Wong also provides extensive coverage of such issues as interactions between international trade in goods and capital movement, external economies of scale, monopolistic competition and differentiated products, oligopoly, welfare economics of international trade, and policy analysis for various models, and he devotes two separate chapters to multinational corporations and international labor migration. New techniques and approaches to these issues are suggested, and new results obtained for many of them. For instance, the discussion of intra-industry trade in the presence of positive transport cost and arbitrage is new, as is the systematic examination of the relationship between international trade in goods and factor mobility with external economies of scale, monopolistic competition, and oligopoly. Of particular importance to trade theorists, these issues serve as the link between neoclassical and imperfect-competition models.

The Organization of Industry collects essays written over two decades—pieces prepared especially for this volume, previously unpublished material, and reprinted articles drawn from numerous sources, many which include additional commentary by the author. The essays are unified by George J. Stigler's careful analysis and by his clear and witty style. In part one, Stigler examines the nature of competition and monopoly. In part two he discusses the forces that determine the size structure of industry, including barriers to entry, economics of scale, and mergers. Part three contains articles on a wide range of topics, such as profitability, delivered price systems, block booking, the economics of information, and the kinky oligopoly demand curve and rigid price. Part four offers a discussion of antitrust policy and includes Stigler's recommendations for future policy as well as an examination of the effects of past policies. "Stigler's writings might well be subtitled 'The Joys of Doing Economics.' He, more than any other contemporary American economist, dispels the gloom surrounding economic theory. It is impossible to confront the subject treated with such humor and verve and come away still believing that economics is the dismal science."—Shirley B. Johnson, American Scholar

The existence of firms with different levels of efficiency within a country plays an important role in this in-depth analysis of industrial and trade policies in a multi-country trade-theoretic framework. Sajal Lahiri and Yoshiyasu Ono examine various industrial policies, R&D subsidies and trade policies under conditions of imperfect competition in a product market created by the presence of Cournot oligopolistic interdependence in production. Trade is defined broadly to include trade in commodity as well as trade in capital, specifically foreign direct investment. While the first part of the book focuses on commodity trade and assumes full employment, the latter considers foreign direct investment and assumes the presence of unemployment. Given the importance of industrial policies and the prevalence of imperfect competition, together with ongoing attention to theoretical issues concerning industrial economics, this research will excite interest amongst researchers, advanced students and policy makers in this field.
