Elhanan Helpman

Elhanan Helpman (born March 30, 1946) is an Israeli economist who is currently the Galen L. Stone Professor of International Trade at Harvard University. He is also a Professor Emeritus at the Eitan Berglas School of Economics at Tel Aviv University. Helpman is among the thirty most cited economists in the world according to IDEAS/RePEc. Helpman's contributions include studies of the balance of payments, exchange-rate regimes, stabilization programs and foreign debt. Most important, however, are his studies of international trade, economic growth and political economy. He is a cofounder of the "new trade theory'' and the "new growth theory,'' which emphasize the roles of economies of scale and imperfect competition. Much of his work in trade, growth, and political economy is summarized in seven books: Market Structure and Foreign Trade (with Paul Krugman), Trade Policy and Market Structure (with Paul Krugman), Innovation and Growth in the Global Economy (with Gene Grossman), Special Interest Politics (with Gene Grossman), Interest Groups and Trade Policy (with Gene Grossman), The Mystery of Economic Growth, and Understanding Global Trade.
