Market Structure and Foreign Trade: Increasing Returns, Imperfect Competition, and the International Economy (The MIT Press) - Softcover

This book is a very substantial research monograph which, as one would expect from the authors, addresses fundamentally important and interesting questions with analytical elegance and clear exposition. It will be required reading for trade theorists and those seeking to become such. -Journal of Economic Literature

Market Structure and Foreign Trade presents a coherent theory of trade in the presence of market structures other than perfect competition. The theory it develops explains trade patterns, especially of industrial countries, and provides an integration between trade and the role of multinational enterprises. Relating current theoretical work to the main body of trade theory, Helpman and Krugman review and restate known results and also offer entirely new material on contestable markets, oligopolies, welfare, and multinational corporations, and new insights on external economies, intermediate inputs, and trade composition.
