A functional relationship between the degree of a country?s comparative advantage in any good and the volume of its net exports of that good to its trading partner is established using a model with per-unit-distance transportation costs between countries' coasts and their interiors. The greater a country's comparative advantage, the greater the transportation cost it can overcome and hence the deeper its exports can penetrate geographically into its trading partner. The internal spatial structure of a country is modeled using cities as the basic spatial units. It is shown that the city closest to the coast will be the largest and have the highest wage rate and residential rental rates, and that population sizes, wage rates, and residential rental rates of cities all fall as one moves inland.

Alan Deardorff was 65 years old on June 6, 2009. To celebrate this occasion, a Festschrift in his honor was held on October 2OCo3, 2009, in the Rackham Amphitheater at the University of Michigan in Ann Arbor. The Festschrift was entitled OC Comparative Advantage, Economic Growth, and the Gains from Trade and Globalization: A Festschrift in Honor of Alan V Deardorff.OCO It was co-organized by two of Professor Deardorff''s former students, Drusilla Brown of Tufts University and Robert Staiger of Stanford University, together with Robert Stern representing the University of Michigan. The first day of the Festschrift involved a series of panels in which invited participants reflected on Professor Deardorff''s contributions, including his writings on: comparative advantage; trade and growth; the gains from trade and globalization; and computational modeling and trade policy analysis. The panel participants prepared written comments, setting out their evaluation of Professor Deardorff''s contributions combined with their own thoughts on the current state of knowledge and analysis of the particular topic. At the end of the first day, Paul Krugman of Princeton University and The New York Times delivered a Citigroup Foundation Special Lecture entitled OC Reflections on Globalization: Yesteryear and Today.OCO All of these papers and Krugman''s lecture are contained in the volume."

'Historians of international trade and trade theory, intellectual historians, and students of trade theory will all benefit from Andrea Maneschi's masterful work, which takes the reader through a considerable amount of the primary literature and presents technical models of international trade with great clarity.' - Sandra Peart, The International History Review

World-renowned economist Ronald W. Jones gets to the essence of international trade theory in this collection of articles that span over half a century of his published work. As the global economy has grown, so too has the need for a deeper rooted understanding of trade -- and its assorted benefits. With clear, simplifying prose, Jones elucidates the Ricardian, Heckscher-Ohlin, and Specific-Factors models of general equilibrium theory. Jones' pioneering work anticipates, among other changes in our time, the creation of far-flung supply chains brought about by the falling costs of service links. The theoretical, technical, and historical insights in the text are peppered with personal notes that capture modern intellectual development in the field, providing a bedrock foundation in international trade for students and practitioners alike.

Rising densities of human settlements, migration and transport to reduce distances to market, and specialization and trade facilitated by fewer international divisions are central to economic development. The transformations along these three dimensions density, distance, and division are most noticeable in North America, Western Europe, and Japan, but countries in Asia and Eastern Europe are changing in ways similar in scope and speed. 'World Development Report 2009: Reshaping Economic Geography' concludes that these spatial transformations are essential, and should be encouraged. The conclusion is not without controversy. Slum-dwellers now number a billion, but the rush to cities continues. Globalization is believed to benefit many, but not the billion people living in lagging areas of developing nations. High poverty and mortality persist among the world's 'bottom billion', while others grow wealthier and live longer lives. Concern for these three billion often comes with the prescription that growth must be made spatially balanced. The WDR has a different message: economic growth is seldom balanced, and efforts to spread it out prematurely will jeopardize progress. The Report: documents how production becomes more concentrated spatially as economies grow. proposes economic integration as the principle for promoting successful spatial transformations. revisits the debates on urbanization, territorial development, and regional integration and shows how today's developers can reshape economic geography.

"I have spent my whole professional life as an international economist thinking and writing about economic geography, without being aware of it," begins Paul Krugman in the readable and anecdotal style that has become a hallmark of his writings. Krugman observes that his own shortcomings in ignoring economic geography have been shared by many professional economists, primarily because of the lack of explanatory models. In Geography and Trade he provides a stimulating synthesis of ideas in the literature and describes new models for implementing a study of economic geography that could change the nature of the field. Economic theory usually assumes away distance. Krugman argues that it is time to put it back - that the location of production in space is a key issue both within and between nations.

China's trade pattern is influenced not just by its overall comparative advantage in labor intensive goods but also by geography. We use two variants of the Eaton-Kortum (2002) model to study China's local comparative advantage. The theory predicts that China's share of export markets should grow most rapidly where China's share is initially large. A corollary is that exporters that have a big market share where China's share is initially large should see the largest fall in their market shares. These market share change predictions are strongly supported in the data from 1996 to 2006. We also show theoretically that since trade costs are proportional to weight rather than value, relative distance affects local comparative advantage as well as the overall volume of trade. The model predicts that China has a comparative advantage in heavy goods in nearby markets, and lighter goods in more distant markets. This theory motivates a simple empirical prediction: within a product, China's export unit values should be increasing in distance. We find strong support for this effect in our empirical analysis on product-level Chinese exports in 2006.

This thesis deals with two theories of international trade: the theory of comparative advantage, which is connected to the name David Ricardo and is dominating current trade theory, and Adam Smith’s theory of absolute advantage. Both theories are compared and their assumptions are scrutinised. The former theory is rejected on theoretical and empirical grounds in favour of the latter. On the basis of the theory of absolute advantage, developments of free international trade are examined, whereby the focus is on trade between industrial and underdeveloped countries. The main conclusions are that trade patterns are determined by absolute production cost advantages and that the gap between developed and poor countries is not reduced but rather increased by free trade.
