A review of the Heckscher–Ohlin framework prompts a noted economist to consider the methodology of economics.In this spirited and provocative book, Edward Leamer turns an examination of the Heckscher–Ohlin framework for global competition into an opportunity to consider the craft of economics: what economists do, what they should do, and what they shouldn't do. Claiming “a lifetime relationship with Heckscher–Ohlin,” Leamer argues that Bertil Ohlin's original idea offered something useful though vague and not necessarily valid; the economists who later translated his ideas into mathematical theorems offered something precise and valid but not necessarily useful. He argues further that the best economists keep formal and informal thinking in balance. An Ohlinesque mostly prose style can let in faulty thinking and fuzzy communication; a mostly math style allows misplaced emphasis and opaque communication. Leamer writes that today's model- and math-driven economics needs more prose and less math.Leamer shows that the Heckscher–Ohlin framework is still useful, and that there is still much work to be done with it. But he issues a caveat about economists: “What we do is not science, it's fiction and journalism.” Economic theory, he writes, is fiction (stories, loosely connected to the facts); data analysis is journalism (facts, loosely connected to the stories). Rather than titling the two sections of his book Theory and Evidence, he calls them Economic Fiction and Econometric Journalism, explaining, “If you find that startling, that's good. I am trying to keep you awake.”

Traditional trade theory explains trade only by differences between countries, notably differences in their relative endowments of factors of production. It suggests an inverse relationship between the similarity of countries and the volume of trade between them. The Heckscher-Ohlin (HO) factor propor­ tions theory derives the determinants of comparative advantage in a world of'two-ness'(two goods, two factors, two countries). It predicts that each country will export that good which uses the country's abundant factor rel­ atively most intensively. The literature on trade offers an impressive number of studies based on the HO theory. The main methodological problems en­ countered in the literature are: first, the appropriate formulation of the HO theorem in a multi-factor, multi-good and multi-country framework; second, proper tests of the HO theory and proper links of the theory to empirical analysis. The relevance of the HO theory began to be questioned when important facts of modern international trade proved to be inconsistent with its theoretical framework. Leontief (1953) tested the factor proportions theory, using the US data for 1947, and found that the US had more labor-intensive exports than imports, which is opposed to both perceptions and estimations of factor endowments. The Leontief Pamdoxcreated doubt as to whether or not actual trade patterns and factor endowments are related as predicted by theory, and caused many controversial discussions with regard to the proper empirical implementation of the factor proportions theory.

During the last 25 year, the neoclassical Heckscher-Ohlin trade theory has been extended to the ‘new'trade theory by including imperfect competition and fixed costs into the analysis of trade relations. Furthermore, these micro-oriented trade models are increasingly used to analyze macro-oriented questions. Chapter 2 of this study investigates the dynamic welfare effects of exposure to trade in a new trade model, which is extended by firm heterogeneity. It is analyzed under which conditions exposure to trade with firm heterogeneity increases or decreases steady state welfare of a country. Chapter 3 uses a new trade model to explore which country-specific conditions give rise to horizontal or vertical multinational activity. Finally, chapter 4 combines the Heckscher-Ohlin model and a new trade model with horizontal multinational firms with the macro-oriented real business cycle model and analyzes the role of goods trade and horizontal multinational firms in international business cycle transmission.

Leading international economists assess Eli Heckscher's contributions to economics and economic history, especially his efforts to bridge the gap between the two.Eli Heckscher (1879-1952) is celebrated for his contributions to international trade theory, particularly the factor proportions theory of comparative advantage in international trade known as the Heckscher-Ohlin theory. His work in both economic theory and economic history is notable for combining theoretical insights with a profound knowledge of economic history and the history of economic thought. In this volume, leading international economists assess the importance of Heckscher's work and its relevance to the contemporary practice of economic history.The contributors first discuss Heckscher's efforts to forge the discipline of economic history by combining both the historian's careful evaluation of sources and the economist's rigorous models. The Heckscher-Ohlin theory of factor proportions is described and tested empirically. Contributors then apply the theory to historical material, including Mediterranean trade in Biblical times, the economic effects of two periods of plague eight centuries apart, and tariff policy in 35 countries from 1870 to 1938. Heckscher's masterly work on mercantilism, the Continental Blockade, and Swedish economic history is also described and appraised in light of recent historical research.ContributorsBenny Carlson, François Crouzet, Lance E.

A collection of essays on the life and work of economist Bertil Ohlin.Bertil Ohlin, international trade theorist, winner of the 1977 Nobel Prize in Economics, and leader of the Swedish Liberal Party for more than twenty years, is considered to be the major single influence on the development of international economics in the twentieth century. This volume, celebrating the centennial of Ohlin's birth, examines his life and his influence on modern economic thought. It also contains the first English translation of his licentiate thesis, in which he first set out his theory of international trade.

Ronald Jones suggests how the basic core of real trade theory can be modified to take into account the increased international mobility of inputs and productive factors.As trade liberalization and the fragmentation of production processes promote greater international exchange of inputs, economists must adjust their thinking on trade issues. Transport costs have plummeted, and the difficulties of communicating between locales half a world apart have practically vanished. In this book Ronald Jones suggests how the basic core of real trade theory can be modified to take into account the increased international mobility of inputs and productive factors. He emphasizes the role of country'hinterlands'and how it is related to agglomeration effects in determining the location of economic activity. After discussing the positive aspects of enhanced mobility for output patterns and market prices, Jones evaluates the significance of globalization for governmental trade policies and public attitudes about regional alliances.
