Education,globalization and catch-up: Scandinavia in the Swedish mirror

This paper estimates and analyses wage inequality trends in Portugal, from 1944 to 1984, a period that comprises the Estado Novo dictatorship and the first decade after the transition to democracy. Wage inequality is measured by the gap between skilled and unskilled labour, and reveals a downward trend in most of the period in analysis. We provide an explanation for the observed trends by looking at the influence of domestic and international forces on changes in the relative supply and demand of skilled labour. According to our findings, the skill premium declined due to the combined influence of two major forces: an increase in the relative supply of skilled labour due to the mass emigration of unskilled labour, and the decrease in the relative demand for skills, related to trade-induced changes stemming from the country's increasing openness, which followed the country's unskilled labour comparative advantages. Our findings point to the conclusion that the impact of openness on wage inequality is related to the country's relative level of development among its major trading partners.     

Trade,technology, and the labour market: impacts on wage inequality within countries

This paper focuses on the widening wage inequality between skilled and unskilled workers within countries and discusses whether trade and technology have contributed to this trend. The paper develops an analytical framework for wage inequality that traces the determinants and their relative roles in wage inequality in different stages of the development of trade theory, especially those considering new evidence after 2011. We find that technology plays a key role in the rise of wage inequality in most countries, while trade plays an increasingly crucial and more complex role in recent years. Skill supply institutions, such as education systems supplying skilled labour or unions participating in wage‐setting processes, suppress the rise of wage inequality in some countries. The paper further outlines the mechanisms through which trade affects wage inequality, including offshoring, firm heterogeneity, labour market frictions and global value chains. We find that trade has indirect effects on technology, which further enlarges the wage inequality among skills. The paper also discusses the policy implications of the impacts of trade and technology on wage inequality.     

Openness, Technological Change and Labour Demand in Pre-Crisis Indonesia

This paper examines the impact of export orientation, import competition, foreign ownership and the rate of capital accumulation on the relative demand for skilled and unskilled labour in pre-crisis Indonesia. Estimates from an interrelated factor demand analysis indicate that openness and foreign ownership, by themselves, acted to raise the relative demand for unskilled workers in the pre-crisis period, while the newness of capital was associated with increased relative demand for skilled workers. Overall, the relative demand for unskilled workers increased yet their relative wage position weakened. These contrasting relative employment and wage changes are consistent with the examined demand shocks and the greater elasticity of supply of Indonesian unskilled relative to skilled labour.     

Institutions, wages, and inequality: The case of Europe and its periphery (1500–1899)

This paper explores the long-run relationship between institutions and wage outcomes in Europe and its periphery. I find that cities that exercised stronger institutional protection of private property experienced: (i) higher levels of both skilled and unskilled real wages, as well as (ii) lower levels of inequality as measured by the skilled–unskilled wage ratio. While the first result corroborates existing work on the positive growth effects of better institutions, the second finding is more novel to the literature. Some explanations are proposed for how stronger institutions can cause an increase in the relative supply of skilled workers, thus lowering wage inequality.     

The Supply Side of the Race Between Demand and Supply: Policies to Foster Skill in the Modern Economy

In his celebrated book on income inequality, Jan Tinbergen (1975) wrote about the race between demand and supply in determining the evolution of wages and inequality. The demand side of the recent labor market is well understood. Skill-biased technical change favors skilled workers in many different economic environments. The supply side is less well understood. In the Netherlands, until recently, the supply side was winning and the returns to education were declining or stagnant. The exact reasons for this phenomenon are not well understood. Recently, however, there is evidence that suggests that the returns to schooling are increasing and that demand is outstripping supply, as it has done in most developed countries around the world. This has produced rising wage inequality. Unless more active supply side measures are undertaken, this trend is likely to continue. This problem, joined with the persistent problem of immigrant assimilation and the growing role of immigrants in the Dutch economy, renews interest in the supply side of the labor market. This lecture examines the determinants of the supply of skills in the short run and the long run. It examines the roles of short- term credit constraints and long-term family factors in fostering or retarding skill accumulation. It summarizes the evidence on a number of policy proposals to foster skills including early childhood programs, programs to alleviate short-term financial pressure, job training and second chance programs, and tax policies. This lecture stresses the cumulative dynamic nature of skill production and the importance of recognizing that skill begets skill in designing suitable policies to reduce inequality and foster economic growth. While the evidence is based on American data, the lessons are relevant for economies around the world. Specific lessons for the Netherlands are emphasized.     

FDI and the labour market: a review of the evidence and policy implications

This paper presents a series of results concerning the labour-marketimpact of inward foreign direct investment (FDI) in the UK.The paper demonstrates that one of the crucial impacts of FDIis to increase wage inequality and the use of relatively moreskilled labour in the domestic firms. This result is found tobe a combination of two effects. First, the entry by a multinationalenterprise (MNE) increases the demand for skilled workers inan industry or region, thus increasing wage inequality. Second,technology spillovers occur from foreign to domestic firms.As a result of these spillovers, relative demand for skilledworkers increases in the domestic firms, further contributingto aggregate wage inequality and skill upgrading. The paperalso considers how FDI impacts upon skill shares by productivitydifferentials between foreign and domestic firms. Finally, thepolicy implications of this are discussed, from the perspectiveof regional development, and the likely effectiveness of attractingFDI to reduce structural unemployment.     

Global Outsourcing and Wage Inequality in Middle-Income Countries: Evidence from South Korea

A substantial number of studies have suggested that global outsourcing can induce wage inequality. As Feenstra and Hanson [(1996a) Foreign investment, outsourcing, and relative wage, in: R. C. Feestra, G. M. Hanson, and D. A. Irwin (Eds.) Political Economy of Trade Policy: Essays in Honor of Jagdish Bhagwati (Cambridge: The MIT Press), pp. 89–127] argued, global outsourcing is comparable to skill-biased technological change in that global outsourcing is more likely to increase the wage of skilled workers rather than their unskilled counterparts. We examine the effects of outsourcing on wage of skilled and unskilled workers in Korea's manufacturing sector with a focus on the dissimilar effects of outsourcing to developed countries (DCs) and less developed countries (LDCs) on relative wage. The results of system and difference GMM estimation based on manufacturing data from 1992 to 2006 indicate that outsourcing to DCs and LDCs have opposite (and significant) effects on relative wage, that is, outsourcing to DCs (LDCs) decreases the wage of skilled (unskilled) workers.     

Wage Differentials in Taiwanese Manufacturing, 1982–1997

The present paper examines the impacts of technological change and trade flows on wage inequality across manufacturing industries. Using micro–level data from the Taiwan Manpower Utilization Survey (TMUS), 1982–1997, a slight decline in the log–wage differential between college and high–school workers is detected during this period. These results indicate that the accelerated growth in the relative supply of college graduates, combined with steady demand growth in favor of more highly educated workers, can largely explain the narrowing wage differentials within Taiwanese manufacturing over the period 1982–1997. In terms of demand–side factors, this study concludes that technology and trade are the two major forces driving the differences in wage inequality across industries.     

A Picture of Wage Inequality and the Allocation of Labor Through a Period of Trade Liberalization: The Case of Brazil

This paper constructs a picture of the labor market impact of trade liberalization in Brazil. We examine the level and dispersion of wages, the skilled wage premium, and employment composition before and after trade liberalization. After trade reform, there was a rise in the returns to college education which, since the share of college workers also rose, is attributable to rising demand. This change did not increase overall wage dispersion because of the small share of college-educated workers and because of decreasing returns to intermediate levels of education.     

What is Behind Increasing Wage Inequality in Mexico?

We evaluate the impact of the educational expansion and changes in labor market institutions on wage inequality among Mexican workers using a simulation technique proposed by Knight and Sabot [The American Economic Review 73(5) (1983) 1132–1136]. We conclude that while increases in the relative rate of return of higher education would have induced an increase in wage inequality, changes in the composition of the educational distribution would have led to a stronger decline in wage inequality. Instead, increased wage inequality is largely explained by changes in Mexican labor market institutions; namely, unionization rate and minimum wages.     

Patterns and Sources of Changing Wage Inequality in Chile and Costa Rica During Structural Adjustment

During their respective periods of structural adjustment, inequality increased more rapidly in Chile than in Costa Rica. Using a new technique which measures the effects of changes in the quantities and prices of individual dimension of human capital on overall wage inequality, we identify changes in wage premiums associated with more education as an important cause of the different inequality outcomes. We present evidence that the different education price effects were due to different rates of growth in the demand for more-educated workers. Furthermore, inequality increased in Chile despite a large equalizing education quantity effect.     

Effects of state-sponsored human capital investment on the selection of training type

Since the 1990s, firms in Japan have reduced their human capital investment in the workplace to minimize costs. Moreover, in response to the increase in the number of non-regular employees and turnover rates, workers need to have greater incentive to make the self-motivated investment in themselves for their self-protection. In this study, we first estimate the effects of workers’ self-motivated investment in themselves on wage rates. Next, we explore who is likely to participate in which training type and accordingly estimate the effects of the self-motivated investment on wage rates by training type. Our estimates controlling for individual-level fixed-effects indicate that the return is significantly positive and particularly high for practical training related to workers’ current jobs, and regular workers tend to self-select these higher-returns programs, while non-regular workers are more likely to enroll in lower-returns programs, such as schooling. This trend in investment in oneself could potentially increase the wage inequality between regular and non-regular workers through the self-selection of training types. Our estimates reveal that receiving the training and education benefit raises the likelihood for workers to participate in a high-return training program regardless of whether they are non-regular or regular workers. This suggests that government benefits on self-investment change workers’ self-selection of training type and serve to promote practical trainings that lead to high returns.     

Deskilling and decline in skill premium during the age of sail: Swedish and Finnish seamen, 1751–1913

The study examines the evolution of skill premium and share at industry level in shipping during the age of sail. We argue that the period from the 1750s to the 1910s represented deskilling for the seamen working in sailing ships. The growth of international trade and shipping during the first era of globalization increased the overall demand for sailors but decreased the relative demand for skilled labor in favor of less skilled ones. This deskilling was associated with a decline in wage inequality, as the premium for high skilled seamen fell relative to mean wages in the shipping industry. The decline in skill premium may have facilitated the growth of trade and shipping, as the relative costs of transport declined. This in turn might have hastened the first era of globalization.     

Hukou system reforms and skilled-unskilled wage inequality in China

In China, rural migrant workers usually cannot get fair treatment due to the hukou system. This paper investigates how hukou system reforms affect the skilled-unskilled wage inequality through the general equilibrium approach. In the basic model, we find that an increase in the strength of hukou system reforms will narrow down the wage inequality if the urban skilled sector is more capital intensive than the urban unskilled sector. In addition, we separately extend the basic model by introducing the endogenous minimum wage and an informal sector, and find that in these two extended cases the main results of the basic model will conditionally or unconditionally hold. When we consider some empirical evidences in China, our models predict that an increase in the strength of hukou system reforms will reduce the wage inequality.     

Wage Consequences of Rapid Tertiary Education Expansion in a Developing Economy: The Case of Thailand

In recent years, Thailand has experienced the emergence of “overeducated” workers as the supply of university graduates in Thailand has outpaced growth in high‐skilled employment opportunities. Using the 2007 to 2009 Thai Labor Force Survey, this paper quantifies the incidence of overeducation and estimates overeducation wage penalties among male university graduates. The results show that the incidence of overeducation is greatest among younger cohorts. Quantile wage regression results suggest that overeducation wage penalties for older workers capture the impact of unobserved low ability on wages. In contrast, persistent wage penalties of 11–26% across the wage/ability distributions for younger workers are consistent with structural imbalances in the Thai labor market. These imbalances make it difficult for university graduates to find jobs commensurate with their level of formal education and to achieve their full earning power. The wage penalties are especially large for new entrants into the labor market.     

Multinational companies and wage inequality in the host country: The case of Ireland

Multinational Companies and Wage Inequality in the Host Country: The Case of Ireland. — In this paper, the authors analyze the impact of multinational companies on wage inequality in a host country. Based on a model, in which the introduction of new technologies leads to increases in the demand for skilled labour and, therefore, to rising wage inequality, they econometrically study the Irish manufacturing sector between 1979 and 1995. They examine inequality between wages for skilled and unskilled labour within the same manufacturing sector. Their results indicate that there is an inverted-U relationship between wage inequality and multinationals, i.e., with the increasing presence of multinationals, wage inequality first increases, reaches a maximum, and decreases eventually.     

全球生产网络、贸易结构与工资差距：来自中国的证据

论文通过建立全球生产网络的中间投入品模型,实证分析中间品贸易对一国技术劳动力和非技术劳动力工资差异的影响。研究发现：加工贸易是中国融入全球生产网络的典型形态;其出口会扩大对技术和非技术劳动力的需求。但技术劳动力的工资上涨幅度要高于非技术劳动力的工资涨幅,从而使相对工资差距扩大。短期内,中间品的进口减少了技术劳动力的需求和就业,但长期来看中间品进口会扩大对技术劳动力的需求,相对工资差距拉大。人力资本投资的供给增长由于未能满足劳动力市场的需求,从而在一定程度上表现为工资差距拉大;但长期来看,人力资本积累机制的完善使得相对工资差距会逐渐缓和。     

Efficiency Wages,Interfirm Comparison,and Unemployment

The paper presents an efficiency wage model where worker effort depends on own wages relative both to wages of other workers in the firm and to similar workers in other firms. First, we show how the Solow conditions are modified if internal comparison effects are at work. Second, we discuss the effect of internal wage comparison on wage inequality within firms. Third, we study unemployment and relative wage determination within a general equilibrium model, and analyze the effect of technological change and various tax policies on equilibrium unemployment and relative wages. Finally, the short-run effects of aggregate demand shocks are analyzed.     

Wage increases, wage convergence, and the Lewis turning point in China

We examine the wage trends of ordinary workers and the wage convergence between unskilled and skilled workers in China. First, we find that wages in all non-agricultural sectors, wages of migrant workers, and wages of hired workers in the agricultural sector have increased dramatically since 2003. Second, through comparing wage differentials between migrant and urban resident workers and between heterogeneous education groups within migrant workers, and by investigating the changes in the contribution of the returns to education to wage differentials, we find that the wages of unskilled and skilled workers have converged. Both the increasing wage trends and wage convergence are interpreted as evidence supporting the hypothesis that China has passed what can be called the Lewis turning point in the industrial sector. We conclude that the sustainability of economic growth in China requires an upgrading of labor market institutions to accommodate the merging of the rural and urban labor forces.     

Pen and tinbergen on income distribution: A review article

Summary The book under review combines a brief survey of the state of the art in income distribution theory, based primarily on the earlier contributions of the authors, with a wealth of information on the reduction (by about 50 percent) of income inequality in the Netherlands over the last 40 years. Furthermore, progress is charted towards a further reduction of inequality between now and 1990. This review argues that labour income is not just determined by (the demand for) technology and (the supply of) education, but also by the bias towards the demand for skilled labour that seems to result from the expansion of public expenditure. It is recommended that this expenditure incidence on the primary distribution of income be further explored in future research programmes, as it is likely to slow down further progress towards equality.
