Firms’ location decision across asymmetric countries and employment inequality

This paper analyzes the effect of globalization (lower trade costs) on production and trade patterns if, firms are vertically linked, stages of production differ in labor-factors intensity and countries differ in labor-factors prices. In order to reflect the “Continental Europe” experience, relative wages are assumed fixed and spatial changes in production are translated into changes in relative (skilled to unskilled) employment levels. The asymmetry in factors prices across countries results in a unique agglomeration equilibrium for a broad range of trade costs. At low trade costs, firms’ location depends on production costs—vertical specialization occurs. This paper also provides a consistent explanation of the observed increase in employment inequality between skilled and unskilled workers in relatively high-unskilled wage countries.     

Technology Adoption,Export Status,and Skill Upgrading: Theory and Evidence

This paper develops a model of trade that features heterogeneous firms, technology choice and different types of skilled labor in a general equilibrium framework to explain within‐industry increase in the relative demand for skilled workers. Its main contribution is to investigate the impact of firms' export and technology choice decisions on skill upgrading. Only firms in the upper range of the productivity distribution produce for the foreign market using high‐technology. Since this technology is skilled‐biased, exporters that resort to modern technologies are more skill intensive. Empirical evidence is also provided to support the model's main predictions using plant‐level panel data from Chile's manufacturing sector (1990–1999).     

Trade between symmetric countries,heterogeneous firms,and the skill premium

Abstract This paper examines the effects of trade liberalization between symmetric countries on the skill premium. I introduce skilled and unskilled labour in a model of trade with heterogeneous firms à la Melitz (2003) and assume a production technology such that more productive firms are more skill intensive. I show that the effects of trade liberalization on wage inequality crucially depend on the type of trade costs considered and on their initial size. While fixed costs of trade have a potentially non‐monotonic effect on the skill premium, a drop in variable trade costs unambiguously and substantially raises wage inequality.     

Wage inequality and skill supplies in a globalised world

We investigate empirically, and explain theoretically, how the relative wages of skilled and unskilled workers vary with their relative supplies in open economies. Our results combine the insights of simple labour market and trade models. In countries that trade, relative wages respond inversely to variation in skill supplies, but the response decreases with the degree of openness to trade and is small in very open countries. To reconcile our results with standard estimates of the elasticity of substitution between skilled and unskilled workers, we allow also for the influence of directed technical change and income elasticity of demand for skill-intensive goods.     

Technology and outsourcing: An explanation to the rising wage gap

The recent phenomenon of widening skilled–unskilled wage gap in both North and South has been either explained by a technological change or by increasing trade or globalization. The paper provides a new explanation and emphasizes that it is neither technology nor trade alone but both that have contributed to the widening wage inequality. It argues, using a two-country occupational choice model, that any technological improvement in North results in a rise in the skilled–unskilled wage gap in North via an increase in the productivity of skilled labor followed by a rise in the same in South via trade or the outsourcing activities of the northern firms. The extent of outsourcing or the number of northern firms that outsource jobs to South is endogenously determined in the model. The paper also analyzes some major economic impacts of such a technological upgradation in North on the southern economy.     

Factor price overshooting with trade liberalization: theory and evidence

This paper develops an intra‐industry trade model with skilled and unskilled labor as factors of production, endogenous accumulation of skilled labor and firm heterogeneity in factor intensities to examine the effect of trade reforms on factor prices. Since exporters are more skill intensive than non–exporters, a decrease in trade barriers initially increases wage inequality between skilled and unskilled workers, as a result of an increase in the relative demand for skilled labor. Over time, however, as agents respond to the change in relative wages by investing in skilled labor, the relative wage of skilled labor decreases. Evidence from Chilean plant–level data supports the idea of factor price overshooting with trade liberalization.     

An analysis of the demand for skill in a growing economy

We construct a trade theoretic model of skill formation with skill as a produced intermediate input. Capital is required for production as well as for education which transforms unskilled labor into skilled. We use this model to reflect analytically on India's rising requirement of skilled manpower. We show that even if growth of capital and supply of skilled manpower match, relative stagnation of unskilled manufacturing sector will magnify the gap between growth in demand and supply of skill. This may happen, for example, if there is a vast pool of workforce who may not have even the basic education to qualify as “unskilled” and excessive capital flows into the skilled sector. Thus a country with lack of education at a very basic level will be forced to import skilled manpower from the rest of the world.     

Skill upgrading and exports

This paper analyzes the effects of international trade on the relative demand for skilled workers in Italian local labor markets. We find that exports cause a sizable skill upgrading in the labor force by increasing the average level of education of the workforce and the share of white-collars workers.     

Trade,technology, and China's rising skill demand1

China has experienced rising wage inequality due to rising relative demand for skilled labour. In this paper, we use a sample of 1,500 firms to investigate the impact of trade and technology on China's rising skill demand. We find that export expansion had a negative direct effect (Heckscher–Ohlin type) and a positive indirect effect (export‐induced skill‐biased technical change) on skill demand; the net effect was found positive and accounted for 5 percent of rising skill demand of the sample firms. We find that technical change in Chinese firms was on average skill‐neutral, but majority foreign‐owned firms experienced skill‐biased technical progress that accounted for 22 percent of the rising skill demand of the sample firms.     

Trade Liberalization and Technology Diffusion

The paper considers the role of technology diffusion and trade liberalization for the catching‐up of structurally backward countries. A New Economic Geography model is presented that accounts for firm entry/exit and international mobility of skilled labor employed in public R&D sectors. This raises the traditional agglomeration effects in a core–periphery setting as firms and mobile factors usually cluster within spatial agglomerations. With international technology diffusion, however, there is a counteracting effect on the traditional agglomeration effects as firms in the periphery also benefit from increasing R&D expenditures in the core lowering entry costs for firms. It is found that the catching‐up of structurally backward countries is spurred not only as a result of trade integration but also because of technology diffusion.     

Skills,Tasks and the Scarcity of Talent in a Global Economy

The scarcity of talent is a tremendous challenge for firms in the globalized world. This paper investigates the role of labor market imperfection in open economies for the usage of talent in the production process of firms. For this purpose, I set up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low‐skilled and high‐skilled workers to perform these tasks. How firms assign workers to tasks depends on factor prices for the two skill types and the productivity advantage of high‐skilled workers in the performance of complex tasks. I study the firms’ assignment problem under two labor market regimes, which capture the polar cases of fully flexible wages and a binding minimum wage for low‐skilled workers. Since the minimum wage lowers the skill premium, it increases the range of tasks performed by high‐skilled workers, which enhances the stock of knowledge within firms to solve complex tasks and reduces the mass of active firms. In a setting with fully flexible wages trade does not affect the firm‐internal assignment of workers to tasks. On the contrary, if low‐skilled wages are fixed by a minimum wage, trade renders high‐skilled workers a scarce resource and reduces the range of tasks performed by this skill type with negative consequences for the human capital stock within firms. In this case, trade leads to higher per‐capita income for both skill types and thus to higher welfare in the open than in the closed economy, whereas – somewhat counter‐intuitive – inequality between the two skill types decreases, as more low‐skilled workers find employment in the production process.     

Trade,Wages, and Specific Factors*

In this paper, we use a multisector specific‐factors model with sector‐specific capital and two mobile factors, skilled and unskilled labor, to examine the effects of trade, technology, and factor endowments on the skill premium in US manufacturing industries. Based on this model and data for the US manufacturing sector from 1958–96, we calculate changes in the skill premium and then carry out a decomposition to identify the changes caused by product price changes (trade), technological progress, labor, and capital endowment changes. The decomposition reveals that trade effects, working through product price changes, caused the skill premium to increase moderately. Changes in capital endowments (new investments) had a positive effect on the skill premium, with the strongest impact during the 1980s, while the effect of technological change on the skill premium varied over time. Finally, changes in relative labor endowments had a negative effect on the skill premium.     

Quantifying the Impact of Trade on Wages: the Role of Nontraded Goods

This paper uses an applied general‐equilbrium model to decompose the effects of changes in trade‐ and technology‐related variables between 1982 and 1996 in the United States on the wages of skilled and unskilled labor. The results indicate that trade‐related variables (tariff cuts, improvement in the terms of trade, and the increase in the trade deficit) had little impact on the widening wage gap. The major factor behind the rise in the skilled wage relative to the unskilled wage was differential rates of growth in skill‐biased technical change across sectors. The paper also highlights the role that nontraded goods play in explaining the wage gap. Finally, the paper presents estimates of how wages would change if the economy moved to autarky. The results show that expanding trade could actually reduce wage inequality, rather than increase it.     

Unemployment of Skilled and Unskilled Labor in an Open Economy: International Trade,Migration, and Outsourcing

We show how international trade, migration, and outsourcing affect unemployment of skilled and unskilled labor, in a framework that integrates the Heckscher–Ohlin model of trade with the Shapiro–Stiglitz model of unemployment. Our approach allows us to analyze changes in not only aggregate unemployment, but also the distribution of unemployment between skilled and unskilled labor. As the analysis demonstrates, the unemployment rates of these two types of labor often move in opposite directions, thereby dampening the change in aggregate unemployment. Results depend on the source of comparative advantage, based on international differences in (for example) unemployment insurance or production technology.     

Globalization,product differentiation,and wage inequality

Abstract This paper develops a two‐country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by firms’ strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than production. Stronger import competition increases innovation incentives, and thereby the relative demand for skill. An intra‐industry trade expansion following trade liberalization can therefore increase wage inequality between skilled and unskilled workers. As long as some industries remain shielded from international competition, the welfare implications of globalization are found to be generally ambiguous.     

Relative Demand for Skills in Swedish Manufacturing: Technology or Trade?

The rate of change in the share of skilled labor has increased steadily over the past 35 years in Swedish manufacturing. A closer inspection of the period after 1970 indicates that, while relative supply changes of skilled labor seem to have been the main driving force behind the growing skill shares in manufacturing industries over the period 1970–85, an acceleration in the relative demand for skills appears to have propelled higher skill shares during the late 1980s and at the beginning of the 1990s. Consistent with such a development is the finding of an increasing degree of complementarity between knowledge capital and skilled labor, and that Swedish manufacturing firms, in recent years, have invested heavily in R&D. There is also some support for the belief that intensified competition from the South has increased the relative demand for skilled labor. However, the impact appears to be small and essentially driven by the textile industry.     

Cross-Country Externalities of Trade and FDI Liberalization

We develop a three-country heterogeneous-firm model and show that FDI liberalization in one foreign country (F1) results in the following: (i) some firms from the home country switch from export to FDI in F1; (ii) skilled labor’s wage rate drops in the home country; (iii) wage inequality between the skilled and unskilled labor decreases; and (iv) some firms from the home country switch from FDI to export to another foreign country (F2). The effects from trade liberalization are just the opposite, but the effects from education improvement are qualitatively the same as FDI liberalization. The cross-country externalities work through the domestic labor market.     

ENDING RESTRICTIONS TO MIGRATION FROM THE NEW EU MEMBER COUNTRIES: SECTORAL TRADE AND REAL WAGE EFFECTS

Most EU-15 countries have kept restrictions to migration from the new member countries but committed to removing them within seven years from the 2004 enlargement. This article predicts the sectoral trade and real wage impact on high-income, mid-income, and low-income members of removing those restrictions, given two extreme scenarios: either all migrants are skilled or all are unskilled. The main effect of skilled migration is the relocation of high-scale economy, skill-intensive industries from mid-income into high-income countries. The main effect of unskilled migration is the relocation of low-scale economy, low skill-intensive industries from low-income into mid-income countries. Both high-income and low-income members would be better off with skilled migration, but those with mid-income would benefit from unskilled migration. ( JEL F1, F15, F22, J31, L6)     

产业内贸易对中国技能 工资差距的影响

本文试图考察产业内贸易对技能工资差距的影响,理论分析表明：它随劳动力条件的变化而变化,在劳动力无限供给条件下它取决于技术劳动力的绝对需求,由于产业内贸易必能刺激技术劳动力的绝对需求,因此必然会扩大工资差距。但在劳动力条件转向有限供给后,它又取决于技术劳动力的相对需求,而产业内贸易未必使之扩大,特别是对两类劳动力替代弹性较大的部门来说,可能会使技术劳动力的相对需求下降,并使技能工资差距收缩。本文基于中国33个产业的5年面板数据验证了上述假说。     

Tax Competition and Economic Integration

This article examines the role of tax competition and economic integration in a core–periphery setting, where agglomeration forces are present. I present a New Economic Geography model, which accounts for firm entry/exit and international mobility of skilled labor employed in the public R&D sectors. In contrast to other literature on tax competition, I focus on its impact on labor migration and net earnings of skilled and unskilled labor. Economic integration is modeled as trade liberalization, an easing of factor mobility restrictions and technology diffusion. I find that tax competition favors skilled labor when trade costs are reduced. In contrast, unskilled labor benefits when factor mobility restrictions are eased and technology diffusion is enhanced.
