The objective of this symposium is to put together some contributions in economic theory with a distinct focus on development questions.Much of early development economics, as typified in the work of Paul Rosenstein Rodan, Arthur Lewis, Ragnar Nurkse, Tibor Scitovsky, Allyn Young, Gunnar Myrdal, Harvey Leibenstein, Albert Hirschman, Amartya Sen and others, was theoretical, though not necessarily in the sense of formal model-building. These authors all felt the need to bring new concepts into economic theory: ideas that would capture the essential features of underdevelopment, and provide explanations of the development process. Existing economic theory, with its focus on competitive markets, depersonalized exchange, steady technical progress, and balanced growth simply did not seem right when matched with the ground realities of underdevelopment: fragmented, imperfect, or just plain missing markets, highly personalized transactions in credit, insurance, or agrarian tenancy, ambiguous or nonexistent property rights, and widespread evidence of poverty traps and historical lock-ins.A fair bit of modern economic theory was born in some of these early development writings. Young's article [40] on increasing returns was perhaps the first systematic study of nonconvexities in economic growth. Rosenstein-Rodan's celebrated paper [32] on post-war intervention in Europe provided a conceptual foundation for modern thinking on coordination failures
