Education bias of trade liberalization and wage inequality in developing countries

The aim of this article is to examine the impact of increased trade on wage inequality in developing countries, and whether a higher human capital stock moderates this effect. We look at the skilled–unskilled wage differential. When better educated societies open up their economies, increased trade is likely to induce less inequality on impact because the supply of skills better matches demand. But greater international exposure also brings about technological diffusion, further raising skilled labour demand. This may raise wage inequality, in contrast to the initial egalitarian level effect of human capital. We attempt to measure these two opposing forces. We also employ a broad set of indicators to measure trade liberalization policies as well as general openness, which is an outcome, and not a policy variable. We further examine what type of education most reduces inequality. Our findings suggest that countries with a higher level of initial human capital do well on the inequality front, but human capital which accrues through the trade liberalization channel has inegalitarian effects. Our results also have implications for the speed at which trade policies are liberalized, the implication being that better educated nations should liberalize faster.     

International competition, downsizing and wage inequality

A country with Cournot competition and free entry experiences an increase of its market size either due to economic growth or international integration of its goods markets. This implied increase in competition leads to shrinking mark-ups and forces firms to reduce overhead costs relative to output. This implies a reallocation at the aggregate level from administrative to productive activities. Relative factor rewards change and wage inequality increases. The factor which loses in relative terms can even lose in real terms. From a quantitative perspective, international competition is demonstrated to be the more plausible cause of rising wage inequality.     

Economic liberalisation,gender wage inequality and welfare

The article develops a 3-sector general equilibrium model appropriate for economies with female labour oriented export sector to examine the effects of economic liberalisation policies on gender based wage inequality. It is assumed that there exist disparities in efficiencies between male and female labour due to skewed access to education and health, and differences in their spending patterns leading to differential effects of respective wages on their nutrition. The results indicate that tariff cut may reduce gender wage inequality, but may have detrimental effects on welfare; while foreign capital inflow may accentuate the inequality, despite improving the welfare of the economy. However, government policies to increase the provision of education and health have favourable effects on gender wage inequality but may be welfare deteriorating. Thus, the article provides a theoretical explanation to empirical evidences of diverse effects of liberalisation on gender wage inequality and explains the possibility of a trade-off between gender inequality and social welfare.     

Public pollution abatement and wage inequality

This paper constructs three-sector general equilibrium models to investigate how public pollution abatement affects the skilled–unskilled wage inequality. In the basic model with full employment, we find that a higher degree of public pollution abatement will decrease the wage inequality if the intensity of skilled labor in the urban skilled sector is sufficiently large and expand or narrow down the wage gap if this intensity is sufficiently small. In the extended models, we consider other four cases, and obtain the results similar or dissimilar to that of the basic model.     

Urban development,excessive entry of firms and wage inequality in developing countries

This paper examines the short and long-term effects of urbanisation, via favourable urban development policies, on income distribution and social welfare for a developing country, in which the urban manufacturing sector is characterised by imperfect competition and free entry. Urbanisation shifts rural workers to the highly productive urban sector, while causing production in urban firms to expand because of scale economies. However, urbanisation may worsen wage inequality between skilled and unskilled labour in the short term. In the long term, urbanisation can attract new firms to the urban sector and favourable urban development policies may result in excessive entry of firms, which can amplify wage inequality in the economy. This entry-amplifying effect is confirmed empirically, especially for low and lower-middle-income countries. If the entry effect is not considered, the impact of urbanisation on wage inequality could be understated by 13% for low and lower-middle-income countries.     

Trade liberalization, wage inequality, and endogenously determined nontraded goods

We examine the boundary between traded and nontraded goods as a channel for trade to impact factor prices. In a two-country, two-factor, continuum-good model, tariffs generate a range of nontraded goods. A tariff reduction has a direct effect to expand a country’s import set and an indirect effect through terms of trade to expand its export set. We show that the export expansion can dominate the import expansion, raising the relative demand for the factor intensively used in production. The result is useful in explaining observed rising wage inequality in developing countries following trade liberalization.     

Trade, technology, and the rise of the service sector: The effects on US wage inequality

This paper uses a multi-sector version of the Ricardo-Viner model of international trade to quantify empirically the effects of technological changes, international trade, changes in the sectoral composition of the economy, and other factors on the US wage premium. The main finding of the paper is that changes in the sectoral composition of the economy were the most important force behind the widening of the wage gap, accounting for about 60% of the relative increase in wages of skilled workers between 1970 and 1996. In essence, capital was reallocated to sectors where it is relatively complementary to skilled workers.     

Access to imported intermediates and intra‐firm wage inequality

We use Chinese firm‐level data from the World Bank Investment Climate Survey to examine the link between importing intermediates and intra‐firm wage inequality. Our results show that intermediate input importers not only have a significant wage premium but also have a greater intra‐firm wage dispersion than non‐importing firms. This pattern is robust when we control for productivity and use trade costs as the instruments. We further investigate the mechanism of how importing intermediates might contribute to both inter‐firm and intra‐firm wage inequality. Our evidence is consistent with three important channels. First, imported intermediate inputs complement skilled labour. Second, intermediates importers are more likely to use performance pay. Third, imported inputs complement innovation and employee training.     

Foreign direct investment and wage differentials in Taiwan

Abstract

The ease of restrictions on foreign direct investment in China since 1990 has attracted a continuous and dramatic flow of outward investment from Taiwan to the mainland. At the same time, the relative wages for skilled workers in Taiwan have risen mildly despite a rapid increase in the share of educated workers in its labor market. The aim of this paper is to explore the linkage between capital outflows to China and the wage share of skilled workers in Taiwan over the period 1991 – 2001. We find that the pattern of changes in relative wages is consistent with shifts in the relative demand for skilled labor. For the most part, the increases in the relative demand for skilled workers could be attributable to within-industry factors. Findings also indicate that outward direct investment to China has a significantly positive impact on the skilled labor wage share.     

Preference heterogeneity, wage inequality, and trade

We consider individuals who value product variety, and who can be skilled or unskilled as workers. Skilled people prefer to consume skill-intensive goods. We show that under plausible conditions an increase in the relative size of the skilled population increases the relative wage of skilled workers, thereby increasing wage inequality. In our two-country model of trade, an increase in the relative supply of skilled labor in either country increases the relative wage of skilled workers, and hence increases inequality in both countries.     

贸易自由化对工资差距的影响及作用机制--基于中国制造业企业的实证研究

本文利用世界银行的中国企业调查数据分析贸易自由化对工资差距的影响,结果表明贸易自由化显著提升企业内工资差距。企业进口投入品的行为使其内部普通员工的最高与最低工资之比提高约50％,总经理与中层经理的工资比提高约30％,中层经理与普通员工的工资比提高约12％－20％。进一步分析表明,自由贸易使企业对高技能劳动力的需求更大,更倾向于采用绩效工资、进行研发投资、提供员工培训和使用计算机,这些因素均导致工资差距的上升。     

Trade liberalization and rising wage inequality in Latin America: Reconciliation with HOS theory

The paper puts forward the hypothesis that the transitory effects of trade liberalization on wage inequality can differ from the long-run outcome. In cases where the HOS theory predicts a decline in wage inequality in the long run, a temporary rise can, nevertheless, occur due to (i) the asymmetries in the speed of contraction in the import sector and expansion in other sectors, and (ii) the capital-skill complementarity in production. The asymmetric contraction and expansion causes a transitory capital accumulation that boosts the relative and the real wage of skilled labor due to capital-skill complementarity. Although the long-run HOS fundamentals are, therefore, dominated in the short run by the transient effects arising due to capital-skill complementarity, the observed rise in wage inequality is nonetheless consistent with the HOS theory appropriately extended to a dynamic setting.     

Trade,foreign direct investments (FDI) and income inequality: Empirical evidence from transition countries

The aim of the article is to verify whether trade and inward foreign direct investments (FDI) may affect income distribution in a sample of 17 Transition Countries (TCs) over the period 1990–2006. In line with most of the previous literature, FDI do not have significant effects on income inequalities, whereas trade, especially when occurs with developed countries, seems to be more relevant. Different results are found when we take into consideration the educational system which represents an important channel through which FDI and trade may affect inequality.     

Income Inequalities and International Trade in Goods and Services: Short- and Long-Run Evidence

In this article, we study the short- and long-run effects of trade openness in services on wage inequalities. The sample covers ten Organization for Economic Cooperation and Development (OECD) countries from 1980 to 2005. We find a differentiated impact of trade in goods compared to trade in services: while trade in goods has a short- and a long-run impact on inequalities, trade in services has only long-run effects. Moreover, we also find that international trade in services has a stronger impact on inequalities than international trade in goods, and this effect does not concern only inequalities between top incomes and low incomes but also between top incomes and median incomes.     

The Impact of Trade Openness on Regional Inequality: The Cases of India and Brazil

Regional inequalities are large in India and Brazil and represent a development challenge. This article aims to determine whether regional inequalities are linked to a country's trade openness. An annual indicator of regional inequalities is constructed for India for the period 1980–2004 and for Brazil from 1985–2004. Results from time series regressions show that Brazil's trade openness contributes to a reduction in regional inequalities. The opposite result is found for India. India's trade openness is an important factor aggravating income inequality among Indian states. In both countries, inflows of foreign direct investment are found to increase regional inequalities.     

劳动禀赋结构和技术效应结构——贸易与工资差距研究范式新探

在回顾文献基础上,本文梳理出贸易影响工资差距的机制,认为在劳动供给结构不变的前提下,工资差距决定于劳动需求结构变动,而劳动禀赋结构和技术效应结构是研究两者关系的重要范式。劳动禀赋结构模型是在两国生产两种产品且技术水平相同的框架下,贸易品由于劳动禀赋结构不同,导致单位成本产出水平变动,进而影响劳动需求结构和工资差距;而技术效应结构模型则是在两国生产一种产品且技术水平不同的框架下,贸易品由于技术效应结构不同,导致相对工资和劳动需求关系曲线变动,进而影响劳动需求结构和工资差距,而且直接效应和间接效应的传导机制有很大差别。     

Skill bias, trade, and wage dispersion

Wage ratios between different percentiles of the wage distribution have moved in parallel and then diverged in the U.S. in the last 50 years. In this paper, I study the theoretical response of wage ratios to skill-biased technical change and trade integration. I build a simple model of heterogeneous technology and heterogeneous workers that features complementarities between the quality of ideas and abilities. I show that changes to the skill bias of technology and to trade costs can both reproduce the observed pattern since (i) they have similar asymmetric effects on productive vs. unproductive firms, and (ii) positive assortative matching in the labor market transmits this asymmetry across high and low skill workers. Focusing on the different channels through which skill-biased technical change and trade integration operate suggests ways to disentangle the magnitude of each.     

Trade openness,tax reform and tax revenue in developing countries

This article investigates empirically whether the effect of tax reform (involving the progressive replacement of trade tax revenue with domestic tax revenue) in developing countries' tax revenue performance (measured by tax revenue‐to‐GDP ratio) depends on the degree of trade openness of these countries. The analysis has used an unbalanced panel data set of 95 developing countries over the period 1981–2015 and the two‐system GMM approach. Results suggest that tax reform is positively and significantly associated with tax revenue performance in developing countries, with the magnitude of this positive effect increasing as countries experience a higher development level. Additionally, and more importantly, countries that further open up their economies to international trade enjoy a higher positive effect of tax reform on tax revenue than countries that experience a lower degree of trade openness. Therefore, these findings should help dissipate the concerns of policymakers in developing countries that greater openness to international trade would further erode their tax revenue, including by lowering their international trade tax revenue. In fact, the implementation of an appropriate tax reform in the context of greater trade openness would generate higher tax revenue, while concurrently allowing countries to reap the well‐known benefits of international trade.     

贸易开放、人力资本与中国能源消耗

文章从贸易开放对中国能源消耗产生的影响这一基本问题出发,将人力资本纳入分析视角,研究了贸易开放、人力资本对中国能源消耗的直接效应和交互效应。利用中国2001-2012年30个省份的统计数据,运用固定效应回归模型和面板门槛回归模型进行了实证研究,结果表明：贸易开放对能源消耗的直接效应呈倒“U”型曲线关系,即在贸易开放水平较低时,提高贸易开放水平将增加能源消耗量并提高能源消耗强度;当贸易开放水平较高时,提高贸易开放水平反而能促使能源消耗量和能源消耗强度降低。人力资本对能源消耗的直接效应显著为负,提高人力资本要素积累将促进地区经济增长从物质资本驱动型向人力资本驱动型转变。贸易开放与人力资本对能源消耗的交互效应在人力资本处于较高的门槛区间时显著为负,说明贸易开放在人力资本较高的地区将促进该地区专业化生产节能降耗的人力资本密集型产品,从而降低地区能源消耗量并提高能源利用效率。     

Foreign Direct Investment,Trade Openness and Economic Growth in Ghana: An Empirical Investigation

Abstract

This paper investigates the long-run impact of foreign direct investment and trade openness on economic growth in Ghana (1970–2011) within the framework of the endogenous growth literature. Adopting the autoregressive distributed lag bounds testing approach to cointegration the results suggest that the interaction of foreign direct investment and exports has been crucial in fostering growth, thus validating the famous Bhagwati hypothesis. From a policy oriented point of view, the study recommends the channeling of foreign direct investment to export-oriented sectors and the promotion of export-led growth strategies in long-term development plans.
