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 economically remote over time.Economic Geography, Human Capital, International Inequality, International Trade

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.

S190 interpretation techniques development and application to New York State water resources

The author has identified the following significant results. The program has demonstrated that Skylab imagery can be utilized to regularly monitor eutrophication indices of lakes, such as chlorophyll concentration and photic zone depth. The relationship between the blue to green reflectance ratio and chlorophyll concentration was shown, along with changes in lake properties caused by chlorophyll, lignin, and humic acid using reflectance ratios and changes. A data processing technique was developed for detecting atmospheric fluctuations occurring over a large lake

L\'evy Processes on Uq(g)U_q(g) as Infinitely Divisible Representations

L\'evy processes on bialgebras are families of infinitely divisible representations. We classify the generators of L\'evy processes on the compact forms of the quantum algebras $U_q(g)$, where $g$ is a simple Lie algebra. Then we show how the processes themselves can be reconstructed from their generators and study several classical stochastic processes that can be associated to these processes.Comment: 13 pages, LATEX file, ASI-TPA/13/99 (TU Clausthal); 6/99 (Preprint-Reihe Mathmatik, Univ.

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/.
