  • Studies on the Distribution of Human Capital and Globalization: An Introductory Overview

    MA Yan

    In this paper, I survey the recent literature that theoretically investigates how globalization is affected by the distribution of skills and the effects of globalization on income distribution. I focus on two types of matching: matching between (the same type and different types of) workers and matching between workers and tasks (industries).

    We analyse the competitive equilibrium and socially optimal allocation of production fragments in a two-country model where there is learning by doing with spillovers between fragments in the home country. We distinguish between forward and backward knowledge linkages, where learning results from producing products that are less (more) complex than the current knowledge frontier with forward (backward) linkages. We compare the pattern of comparative advantage in the competitive and socially optimal cases, and compare the intensive and extensive margins of fragments produced at home in the two cases. We establish a sufficient condition for the range of fragments produced at home to be non-decreasing with forward linkages. We also show that with backward linkages, the home country will produce some fragments in the neighbourhood of the steady state that are more complex than those produced in the steady state. © 2013 Wiley Publishing Asia Pty Ltd.

    This paper constructs what we call a quality-differentiation model of Chinese trade. This model captures some salient features of Chinese trade and allows us to analyze the impact of trade liberalization on wage inequality. At present, Chinese trade displays the following features: high-quality cars are imported and low-quality cars are produced and consumed domestically, for which some parts are imported. These features lead us to consider trade liberalization as two types of tariff reduction: namely, a tariff reduction on final quality-differentiated goods and a tariff reduction on intermediate goods. This study shows that the two types of tariff reduction have completely different effects on wage inequality. Moreover, the results show that welfare inequality and wage inequality change in opposite directions when the tariff on final quality-differentiated goods is reduced.

    This paper investigates the Rybczynski theorem, the Stolper-Samuelson theorem, and the Heckscher-Ohlin theorem in a two-factor vertical production chain model of trade. For this purpose, capital is introduced into the model of Yano and Dei [Yano, M., & Dei, F. (2003). Trade, vertical production chain, and competition policy. Review of International Economics, 11(2), 237-252.]. A primary analytic device is the economy-wide production curve. This Curve is derived under autarky and free trade, respectively.

    In this study, we developed a model of global supply chain to investigate how globalization affects global supply chains and make use of the data from international input-output table to empirically test our theoretical results. In addition, we theoretically and empirically analyzed the spillover effect of foreign direct investments and firms' decisions on whether to perform foreign direct investments. Moreover, we theoretically examined the effects of distributions of human capital on task trade, wages and welfare, and provided a prediction for future empirical study. Finally, we theoretically investigated the effects of the fragmentation of production processes internationally on the earth environment and also examined the effects of environment protection polices on environment and welfare.

    This research project explores the engines of economic growth in both developed and developing countries. More specifically, I have investigated the following topics: (1) The impacts of the distribution of human capital on economic growth and income distribution in developed countries; (2) The timing of an innovating firm to relocate the production of a new product from the developed country to the developing country, and the interaction between the production location and the rate of quality improvement; (3) The impacts of two types of knowledge linkages on the internationally fragmented production process and global welfare, respectively; (4) The impacts of task characteristics on the internationally fragmented production process. In dealing with each topic, I developed a specific trade model with some new features that have not been considered in the existing literature. Owing to these new features, I successfully obtained some findings that would contribute to the literature.
