The Relative Sophistication of Chinese Exports

This paper examines the relative "sophistication" of China's exports to the United States along two dimensions. First, I compare China's export bundle to those of the relatively skill- and capital-abundant members of the OECD as well as to similarly endowed U.S. trading partners. Second, I examine prices within product categories to determine if China's varieties command a premium relative to its level of development.

Distance, Skill Deepening and Development: Will Peripheral Countries Ever Get Rich?

This paper models the relationship between countries' distance from global economic activity, endogenous investments in education, and economic development. Firms in remote locations pay greater trade costs on both exports and intermediate imports, reducing the amount of value added left to remunerate domestic factors of production. If skill-intensive sectors have higher trade costs, more pervasive input-output linkages, or stronger increasing returns to scale, we show theoretically that remoteness depresses the skill premium and therefore incentives for human capital accumulation. Empirically, we exploit structural relationships from the model to demonstrate that countries with lower market access have lower levels of educational attainment. We also show that the world's most peripheral countries are becoming increasingly remote over time.

Distance, skill deepening and development : will peripheral countries ever get rich?.

This paper models the relationship between countries' distance from global economic activity, endogenous investments in education and economic development. Firms in remote locations pay greater trade costs on both exports and intermediate imports, reducing the amount of value added left to remunerate domestic factors of production. If skill-intensive sectors have higher trade costs, more pervasive input–output linkages or stronger increasing returns to scale, we show theoretically that remoteness depresses the skill premium and therefore incentives for human capital accumulation. Empirically, we exploit structural relationships from the model to demonstrate that countries with lower market access have lower levels of educational attainment. We also show that the world's most peripheral countries are becoming increasingly economically remote over time.

Comparative Advantage and Heterogeneous Firms

This paper presents a model of international trade that features heterogeneous firms, relativeendowment differences across countries, and consumer taste for variety. The paper demonstrates thatfirm reactions to trade liberalization generate endogenous Ricardian productivity responses at theindustry level that magnify countries' comparative advantage. Focusing on the wide range of firmlevelreactions to falling trade costs, the model also shows that, as trade costs fall, firms incomparative advantage industries are more likely to export, that relative firm size and the relativenumber of firms increases more in comparative advantage industries and that job turnover is higher incomparative advantage industries than in comparative disadvantage industries.Heckscher-Ohlin, international trade, inter-industry trade, intra-industry trade, trade costs,entry and exit

U.S. Imports, Exports, and Tariff Data, 1989-2001

This paper describes the updating of the NBER trade dataset, which now provides U.S. import and export values to the year 2001, disaggregated by Harmonized System (HS), Standard International Trade Classification (SITC), and the U.S. Standard Industrial Classification (SIC) categories. In addition, U.S. tariff data at the HS level have been added for the years 1989-2001. Earlier CD-ROMs distributed by the NBER described data on U.S. imports and exports from 1972-1994, and these values have been slightly modified for 1989-1994 and then updated to 2001. Together with the earlier data, there are now 30 years of disaggregate U.S. trade data available to researchers. These data, along with the tariff information for 1989-2001, are all available over the internet at www.nber.org/data/.

Product Choice and Product Switching

This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than 40% of firm output and almost half of existing products. The theoretical model incorporates heterogeneous firms, heterogeneous products, and ongoing entry and exit. In equilibrium, firm productivity is correlated with product fixed costs, with the most productive firms choosing to make the products with the highest fixed costs. Changes in market structure result in systematic patterns of firm entry/exit and product switching.

A Note on the Empirical Implementation of the Lens Condition

Deardorff [Journal of International Economics 36 (1994) 167-175] offers an intuitively appealing test for factor price equality (FPE). He demonstrates that FPE is impossible if the set (i.e., lens) of points defined by regional factor abundance vectors does not lie within the set of points defined by goods' input intensities. This note demonstrates that empirical implementation of the lens condition is problematic if the "true" number of either goods or regions is unknown. We show that satisfaction of the lens condition is more likely when goods are relatively disaggregate compared to regions.
