Wage Gaps Large and Small

The law of one wage does not strictly hold, nor should it be expected to hold, in contemporary labor markets. The law of one wage, however, provides a surprisingly good first approximation of the structure of U.S. wages. This generalization is drawn from research on a diverse set of topics: the Mincerian wage equation and earnings imputation, union wage differentials, product market regulation and the labor market, wages in male and female jobs, the wage effects of military service, and interarea wages and cost of living.     

The labor market in Tokugawa Japan: Wage differentials and the real wage level, 1727–1830

Tokugawa economic history provides quite an interesting example of the workings of the labor market: In the Tokugawa period a contraction in occupational wage differentials occurred concurrently with a rise in real wages. This paper deals with these aspects of wage change and a general set of problems which has arisen about them. The first section sets out these problems; the second deals with the evidence on wage differentials and real wages in Kinai from 1727 to 1830. The third provides a theoretical framework to explain the findings; finally the last section examines the implications of the findings.     

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。     

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.     

Occupational Segregation and Gender Wage Differentials: Evidence from Malaysia

In Malaysia, the participation of women in the labor market has increased over time. However, occupational segregation and wage differentials continue to be prevalent between men and women in the labor market. The present paper investigates gender‐related occupational segregation and wage differentials based on data collected from 7135 working households in Peninsular Malaysia in 2011. The wage decomposition model introduced by Brown et al. (1980) is used to examine the determinants of gender‐related wage differentials. The results suggest that differences within occupations account for the largest portion of the wage gap between men and women. The results also indicate that wage discrimination within occupations plays an important role in the gender wage gap, while sample selection bias plays an important role in the examination of gender wage gaps.     

MIGRATION,LABOR MARKET FLEXIBILITY,AND WAGE DETERMINATION IN CHINA: A REVIEW

This paper reviews economic studies on rural‐urban migration issues in China. The paper focuses on four issues: the household registration system in China, the profile of the migrants, explanations for rural‐to‐urban migration, and the interaction between migration and labor market evolution, with special reference to labor market segregation, labor market flexibility, and wage differentials. The paper concludes with suggestions for further research topics.     

Product market competition, unemployment and income disparities

Product Market Competition, Unemployment and Income Disparities. — We discuss how promoting competition in product markets affects unemployment and wage differentials. We examine a general equilibrium model with real wage rigidities in labor markets and market power in product markets. We illustrate how more intense competition reduces unemployment. A decrease of markups would induce an increase of real wages if real wages were flexible. This enables the employment of more low-skilled people above a real reservation wage. More intensive competition, however, widens wage and income differences between low-skilled and high-skilled workers. Differences of income distributions across countries could also be caused by differences in the intensity of product market competition.     

贸易开放与工资差距——基于中国制造业行业面板数据的实证研究

本文在中国贸易非均衡发展现状基础上,构建计量模型,从商品价格机制、技术进步机制和生产率进步机制角度探讨中国贸易开放影响中国制造业行业间工资差距的具体传导机制。研究发现:(1)就制造业总体而言,贸易主要通过技术进步机制和劳动生产率机制来影响行业工资,造成行业间工资差距的扩大。(2)具体而言,劳动力密集型行业中,进出口贸易、资本密集度和劳动生产率共同作用于行业工资差距;在资本密集型行业中,进口贸易、资本密集度和劳动生产率是扩大工资差距的动因;在技术密集型行业中,出口贸易是工资差距扩大的主导因素。     

Working hours in the European periphery: The length of the working day in Spain, 1885-1920

This paper studies the decline of the working day in Spain from 1885 to 1920. The decline was more continuous than previously thought. Differences in hours reinforce wage differentials, showing labor markets were not well integrated. Cross-sectional and time-series analysis suggests that hour reductions reflect a labor supply rather than a labor demand effect. Given the comparatively slow growth of real wages in Spain from 1870 to 1920, the Spanish case shows that international convergence in hours of work must have been stronger than convergence in wages.     

Labor market segmentation by industry sectors and wage gaps between migrants and local urban residents in urban China

This paper explores the influence of labor market segmentation by industry sectors on the wage gap between rural-to-urban migrants and local urban residents in China in the 2000s. Using Chinese Household Income Project (CHIP) survey data and the results based on the Brown decomposition method, the results indicate that the influence of intra-industrial differentials is greater than the influence of inter-industry differentials in both 2002 and 2013. The influence of the explained component of the intra-industry differentials is larger in both 2002 and 2013, and the influence of the unexplained component of the intra-industrial differentials rises steeply from 2002 to 2013. These results show that the individual characteristic differentials (e.g. human capital) in the same industry sector is the main factor causing the wage gap in both 2002 and 2013, and the problem of discrimination against migrants in the same industry sector became more serious from 2002 to 2013.     

Wage differentials between urban and rural-urban migrant workers in China

Since the end of the 1980s, the number of migrants working in the urban labor market has increased dramatically. However, migrant workers are treated differently from urban workers. In this paper we examine the labor market discrimination against rural migrants from the point of view of wage differentials using CHIP-2007 data. We apply Jann pooled method to deal with index number problem and use Heckman two step model to correct selection problem when decomposing the wage gap. The decomposition results show that a significant difference in wage gains persists between the two groups as late as 2007. In 2007 migrants only earned 49% of urban workers' income and 17% of the wage gap cannot be explained by observed factors. In detail, differences in educational attainment, work experience and distribution across industry, occupation, and ownership of enterprises account for most of the explained wage gap.     

The role of migration in regional wage convergence: Evidence from Sweden 1860–1940

Sweden experienced a decline in inter-county real wage differentials for agricultural workers between 1860 and 1940, historical evidence of early labor market integration well before widespread unionization in agriculture occurred. By means of dynamic panel data analysis, this paper examines whether internal and external migrations caused real wage beta convergence across Swedish counties. To account for statistical problems such as endogeneity of migration, time-invariant county characteristics and autocorrelation in the regression model, we adjust our estimates using fixed effects, instrumental variables and GMM. The preferred model shows that both internal and external migrations contributed to wage convergence before the First World War and internal migration mainly during the interwar years. The agglomeration effects of urbanization were not sufficiently pervasive to offset the labor supply effects of internal and external migrations.     

Employment,income and economic identity in the U.S. virgin islands

The explosive tourism-led growth experienced by the U.S. Virgin Islands during the 1960s and early 1970s reflected the duality of the Virgin Islands’ socioeconomic identity. Although growth was dependent on the U.S. economy and U.S. policies, it also reaffirmed the links the Virgin Islands had developed with the Eastern Caribbean labor market in spite of their unique history as a Danish and then an American colony. Relatively large scale inflows of Eastern Caribbean labor caused both general and relative wage effects, compression of the wage and income structures, and redistribution of income away from labor. Increased labor market segmentation exacerbated the inherent ambivalence of the Virgin Islands’ Eastern Caribbean identity. The nature of the transformation of employment and income in the Virgin Islands undermined the benefits derived by the indigenous labor force and established the bases of subsequent socioeconomic conflict.     

THE EFFECTS OF WORKERS' REGION OF BIRTH ON LABOR MARKET OUTCOMES IN THE REPUBLIC OF KOREA

In this paper, we investigate empirically whether there are differences in labor market outcomes according to workers' region of birth. We also investigate whether wage differentials by region of birth are due to taste discrimination, statistical discrimination as measurement error, or both of these things. The empirical analyses based on the Korean Labor and Income Panel Study (KLIPS) data show the following. First, Honam‐born workers have a higher migration ratio to other regions than Youngnam‐born workers. Second, workers born in other regions have a higher propensity to become contingent workers and are paid significantly lower wages than Seoul/Kyonggi‐born workers. Finally, our empirical tests support the third hypothesis that wage differentials by region of birth are attributable partly to statistical discrimination as measurement error and partly to taste discrimination. We rejected a hypothesis based solely on taste discrimination as well as a hypothesis based solely on statistical discrimination as measurement error.     

Modeling the age and age composition of late 19th century U.S. immigrants from Europe

Using panel data on 12 European source countries that are followed for 26 years (1873-1898), this paper studies age-specific emigration rates and the age composition of U.S. immigration. Two age groups are the focus of attention, 15-40 and over 40. Emigration-rate models and compositional models that satisfy adding-up conditions are estimated by the Hausman-Taylor Instrumental Variable approach. Younger migrants responded more strongly to job opportunities than to wage differentials, whereas older migrants responded more strongly to wage differentials. Both age groups tended to follow recent past migrants to the U.S. Relatively many younger (and relatively fewer older) migrants came from countries with higher percentages of their work forces in agriculture. Higher source-country birthrates discouraged younger migrants, presumably by raising the cost of family migration.     

Migrant information,job search and the remigration decision

"Labor force migration poses two important questions for the economist. The first concerns the nature, magnitude and direction of labor force response to perceived earnings differentials over space. The latter and more complex question concerns the effectiveness, or efficiency, of this response--namely migration--and other market mechanisms in reducing these earnings differentials over time." Both questions are addressed in this paper "by examining relationships among: (1) quality of information obtained prior to a move, (2) search duration at the migration destination, and (3) the likelihood of subsequent (perhaps corrective) remigration." These relationships are analyzed using the human capital model of migration-remigration and data from the 1970 U.S. census.     

Labor force competition and the black-white wage gap

Have the increasing numbers of women and immigrants in the U.S. labor force adversely affected the relative earnings of black men? A recent article in this journal argued that they have, based on empirical analysis of 1970 census data. The present study begins with a critique of both the theoretical assumptions and the empirical methods of this earlier article. A regression analysis of 1980 census data is then undertaken, which indicates that recent immigration has not had a negative impact on the relative wages of central-city black men. The findings also suggest that while higher rates of female labor force participation are statistically associated with lower black-white wage ratios, this effect is limited to teenagers.     

An empirical analysis of the unit labor cost-product price relation in the U.S. economy

This article tests for cointegration between unit labor costs and the level of product prices in four sectors of the U.S. economy: the aggregate business sector, the nonfinancial corporate sector, durable manufacturing, and nondurable manufacturing. A finding of cointegration for most specifications supports the existence of long-run labor market equilibrium for producers and suggests estimation of error-correction models to examine the dynamic relationships. In every sector except nondurable manufacturing, error-correction model estimates indicate there is a mutual feedback relationship between unit labor costs and prices. Controlling for deviations from full employment, oil price shocks, and the Nixon wage and price controls, the results also provide evidence of significant nominal wage indexation in U.S. labor markets. Throughout the economy there appears to exist both effective neoclassical wage and price adjustment mechanisms to maintain labor market equilibrium and short-run rigidities which may contribute to deviations from full employment outcomes.     

Trade,FDI, migration,and the place premium: Mexico and the United States

Large wage differences between countries (“place premiums”) are well documented. Theory suggests that factor price convergence should follow increased migration, capital flows, and commercial integration. All three have increased between the United States and Mexico over the last 25 years. This paper evaluates the degree of wage convergence between these countries during the period 1988 and 2011. We match survey and census data from Mexico and the United States to estimate the change in wage differentials for observationally identical workers over time. We find very little evidence of convergence. What evidence we do find is most likely due to factors unrelated to US–Mexico integration. While migration, trade, and FDI may reduce the US–Mexico wage differential, these effects are small when compared to the overall wage gap.     

Accident risk compensation in late imperial Austria: Wage differentials and social insurance

We test for substitutability of wage differentials and accident insurance benefits in late imperial Austria. We establish that workers earned compensating wage differentials and that accident insurance benefits acted as substitutes for those market-based differentials. We estimate that an average expected value of insurance benefit reduced the compensating wage differential by about one-third. The shift from negligence liability to compulsory accident insurance thus induced both gains to workers in the form of income certainty, and losses in the form of smaller risk differentials and thus lower wages.
