Heterogeneity in factor endowments and the degree of specializations induced by comparative advantages are among the crucial factors that affect the overall productivity of the economy. Few studies, however, investigate what strengthens such endowment-related specialization patterns in the agricultural sector in low-income countries, although such evolutions have profound effects on the role of factor endowments in households’ behaviors. This is in contrast to well-established international trade theory, such as the Heckscher–Ohlin theorem which describes how heterogeneity in endowment across countries gives rise to comparative advantages for specialization and trade. We partly fill this critical knowledge gap by providing a set of evidence from Nepal, which is a country that has historically been dominated by smallholder farmers and yet has recently been experiencing rapid structural transformation within the agricultural sector. Specifically, we show the following: the agricultural sector in Nepal has experienced a significant increase in returns-to-scale (RTS) in production in recent years during the process of growing adoptions of agricultural mechanization through the custom-hiring market. Such increase in RTS has primarily strengthened the linkages between factor endowment heterogeneity (across farm households) and their specialization behaviors in labor, land, and the agricultural capital market. Both cross-section and panel-data of households in Nepal extracted from Nepal Living Standards Surveys are used to generate this evidence. We find that rising RTS associated primarily with tractor use growth has been inducing greater exploitations of comparative advantages; agricultural households have been increasingly specializing in exchanges of production factors, services, and outputs, in ways consistent with predictions based on their relative factor endowments. Specifically, the rise in RTS has induced households with more labor, land, and capital endowments to rent out their labor, land, and credit, respectively, within the agricultural sector, while increasingly renting-in the other factors with which they are less endowed. The results suggest that understanding factor endowments heterogeneity among agricultural households is becoming increasingly important for effective agricultural policy designs in countries like Nepal, where employment shares in the agricultural sector remain high despite the growth in mechanization.

Changing Patterns of Global Trade outlines the factors underlying important shifts in global trade that have occurred in recent decades. The emergence of global supply chains and their increasing role in trade patterns allowed emerging market economies to boost their inputs in high-technology exports and is associated with increased trade interconnectedness.The analysis points to one important trend taking place over the last decade: the emergence of China as a major systemically important trading hub, reflecting not only the size of trade but also the increase in number of its significant trading partners.

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.

Seminar paper from the year 2009 in the subject Economics - International Economic Relations, grade: 1.3, University of Applied Sciences Mainz (School of Business), course: International Business Environment, language: English, abstract: This paper gives an overview of international trade theories. It demonstrates that the fundamentals of classical and neoclassical theories are still relevant today, albeit they have been adjusted and developed. Modern theorists explain international trade with more realistic approaches, such as Krugman et al.'s New Trade Theory or Porter's theory of National Competitive Advantage. The New Trade Theory includes the existence of increasing return of scale to describe and analyze world trade more accurately. Porter's theory of National Competitive Advantage explains international trade as a consequence of productivity differences between nations due to diverse environments and cultures within economies. Dunning and Porter take a globalized world economy into account in order to describe today's trade. The classical theories of Ricardo and Heckscher-Ohlin are limited in describing today's inter-national trade. However, they are still important factors which contribute to the explanation of real-world trade relations. Ricardo's theory describes inter-industry trade which in fact exists between Northern and Southern economies. The relevance of the approach as an explanation of global trade has to be limited due to the fact that inter-industry trade has only a small impact on international trade. De facto, only a small percentage of world trade can be described by North-South trade. The H-O-T describes intra-industry trade between differently endowed countries, which has been exemplified by the trade between Japan and Taiwan. This is true for the case that countries are in different developmental stages combined with different factor endowments. However, when countries' economies stabilize, their factor endowments approximate. Therefore,
