Are China’s sovereign credit ratings underestimated?

A key implication of Becker’s (1957) work on discrimination is that greater product market competition can reduce employment discrimination generally, and discriminatory wage gaps in particular. Using US data on manufacturing wages and import exposure, we explore whether increased competition, in the form of a heightened exposure to imports, reduces the racial wage gap. Our findings support Becker’s contention. We find that import exposure helped narrow the racial wage gap by about 1.4 percentage points between 1983 and 1993. The effect is especially pronounced among the most disadvantaged: unskilled Southern workers. For them, import exposure helped reduce racial wage disparities by 2.2 percentage points.     

Does union membership reduce gender earnings differentials? Evidence from employer–employee matched data in China

This paper examines whether union membership reduces gender earnings differentials in the Chinese labour market using an employer–employee matched data set. We have three main findings. First, union membership helps reduce the gender differentials in hourly wage and monthly allowance, but not in monthly basic wage and yearly bonus. Second, ensuring that female workers receive overtime pay is one way by which union membership helps reduce the gender earnings differentials. Third, controlling for firm fixed effects reduces the effect of union membership on the gender gap in hourly wage and monthly allowance, which means that the unobserved firm characteristics might impact the effect of union membership on gender earnings differentials.     

The Employment Effects of Gender Discrimination in Australia 1994–95

Interpreting the unexplained component of the gender wage gap as indicative of discrimination, the empirical literature to date has tended to ignore the potential impact wage discrimination may have on employment. Clearly, employment effects will arise if discrimination lowers the female offered wage and the labour supply curve is upward sloping. The empirical analysis employs the ABS Income Distribution Survey 1994–95 and finds evidence of both wage and associated employment effects. The analysis is replicated for the earlier period 1989–90. A comparison across time is of interest given the substantial deregulation of the Australian labour market over the period.     

How do Labor Unions Influence the Gender Earnings Gap? A Comparative Study of the US and Korea

Abstract

This paper provides a comparative study of the United States and Korea regarding the effects of unions on gender earnings gaps in 2004. Using datasets representative of the population of the US and Korea, this contribution shows that gender differences in the workers' observed characteristics and the unobserved component reduce gender earnings gaps in union jobs in both the US and Korea. Fringe benefits in the union sector attract women workers with higher labor market qualifications into the union sector and thereby reduce the gender earnings gap in this sector. The study finds that this self-selection process in the union sector is stronger in Korea than in the US, but the seniority-based wage system that prevails in the Korean union sector widens the gender earnings gap.     

Sex Differentials in Earnings in the South Korean Labor Market

We examine gender differences in earnings among South Korean workers in 1988 – the year the South Korean National Assembly enacted the Equal Employment Opportunity Act. Using the "88 Occupational Wage Bargaining Survey on the Actual Condition," we calculate women's mean earnings as a percentage of men's mean earnings by major industrial category and educational attainment. We find a larger wage gap among clerical and sales workers than production workers or professionals. Generally, the more education a woman has, the smaller the gap between her earnings and those of her male counterparts. Women with a middle-school education have a mean income 53.5 percent that of comparable men, while the female-to-male wage ratio among college graduates is 76.1 percent. We analyze wage differences separately for women and men. Following Ronald Oaxaca's (1973) work, we decompose male–female wage differentials. We also calculate a discrimination coefficient. Our work shows that, all else equal, men earn from 33.6 percent to 46.9 percent more than women with comparable skills. We attribute the difference to gender discrimination.     

Housework and the Wages of Young, Middle-Aged, and Older Workers

This article uses samples of young, middle-aged, and older married workers drawn from the Panel Study of Income Dynamics to examine whether the effect of housework time on wages differs among these age groups. Results from OLS, fixed effects, and panel data instrumental variables models show that young and middle-aged wives are the only groups for which the authors find consistent evidence of a housework effect on wages. Each additional hour of housework reduces their wages by 0.1–0.4%. Additionally, the analysis finds evidence that for young workers, housework time is an important determinant of the male/female wage gap. (JEL J16 , J22 , J31 )     

The role of supervisors in the determination of wages and wage gaps

This article considers labour market discrimination by supervisors as a potential contributor to racial and gender wage gaps. Empirical analysis reveals evidence that all workers, except Hispanic males, earn significantly higher hourly wages when working for a supervisor of the same race and sex as themselves. Furthermore, the results suggest that sex has a larger impact on wages than race for workers with white supervisors, while race has a larger impact on wages than sex for workers with minority supervisors. Based on past research, we theorize that the degree of labour discrimination workers face may also be dependent upon the location and size of the firm in which they are employed. However, decomposing the samples by firm location and size suggests that these two factors cannot adequately explain the observed matched supervisor–worker wage effects, which supports the notion that these wage effects are largely driven by factors other than supervisor discrimination.     

Gender Wage Gaps in Post-Reform Rural China

The present paper examines the impact of market reforms on gender earnings gaps in China's rural economy using two cross-sections of data for 1988 and 1995. The results show that the raw gender wage gap was sizeable and predominated by the unexplained part. However, no evidence was found to suggest that the reform policies and market competition led to any measurable increase or decrease in wage discrimination during the period of investigation.     

Gender wage differentials and discrimination in Korea: comparison by knowledge intensity of industries

This study estimates the relative size of the non-productivity-related gender wage gap across industries with differing knowledge intensities. More specifically, a gender wage premium was estimated from a modified Mincerian earnings equation, and an Oaxaca's discrimination coefficient was computed. Empirical evidence indicates that gender wage differentials tend to be less subject to potential discrimination in knowledge-based industries than in other industries with lower knowledge intensity. The estimated discrimination effect is least noticeable in top hierarchical occupations such as professionals and technicians, while it is most sizeable in production workers and sales/service workers, regardless of industrial affiliation.     

Trade unions vs. statistical discrimination: Theory and application to post-apartheid South Africa

A simple model of statistical discrimination is analyzed, which captures some stylized facts of the South African labor market. It shows that this type of discrimination disappears when the wage rates are determined by efficient bargaining between a representative firm and a union, with endogenous membership. This may explain why the wage gap between Black and White workers in post-apartheid South Africa is smaller among unionized workers than among non-unionized ones.     

New technology and old institutions: An empirical analysis of the skill-biased demand for older workers in Europe

Using panel data from nine European countries over the period 1970 to 2007, we examine the impact of information and communication technology (ICT) on the demand for older workers (aged 50 and over). We find evidence of a decrease in demand for older workers in the 1970s and 1980s. It can be argued that the impact of ICT on demand for older workers is skill-biased. However, the skill-biased demand for older workers is mainly reflected in the skill-biased changes in employment shares rather than relative wages. There is some evidence of a gradual deskilling of older workers. We find that labour market institutions such as the national minimum wage, social pacts on wage issues and union density mostly benefit skilled older workers, while coordination of wage setting, extension of collective agreements, social pacts on pensions and centralisation of wage bargaining can alleviate the adverse effects of skill-biased technological change.     

Earning Curves and Wage Curves

Using British county data for full-time male manual workers we extend earlier work to investigate wage and earning curves. We distinguish between total earnings and hourly wages for standard hours, uncontaminated by overtime premium. Using data from 1980–1995 we find that earnings behaviour is dominated by volatile hours in the short run, while wage growth is highly sensitive to the level of unemployment as in the classical Phillips curve with macro data. Macro evidence for sticky wages is thus confirmed at the local level, and the wage curve of rapid adjustment is rejected for normal hourly wages.     

No End to the Racial Wage Hierarchy in South Africa?

The South African apartheid system formally ended with the election of the African National Congress at the first all-race elections held in 1994. As a result, racist policies such as color barring, that particularly hindered the advancement of black workers throughout the apartheid period, are no longer legal. Yet the legacy of apartheid may endure as a result of both the persistence of racial differences in human capital attributes and the possible continuation of discriminatory practices within employment. In this paper the authors examine the evolution of the racial wage hierarchy in the early post-apartheid era against the background of the long-term decline in racial wage disparities observed over the last years of the apartheid regime. They find evidence that the position of black workers between 1995 and 1997 actually deteriorated relative to the overall geometric mean wage, while that of colored, Asian, and white workers improved.     

Privatization and enterprise wage structures during transition: Evidence from rural industry in china

Wage structures in transition economies usually diverge significantly from their centrally–planned predecessors. Using a matched sample of employees and enterprises, we examine the effects of privatization on wage structures in rural industry in two provinces of China. We find that privatization was associated with increased wage and earnings inequality. We report increased returns to education, increased returns to experience for mid–age workers, and increases in gender wage discrimination. We find these aspects of wage structures are similar in different types of private ownership emerging from the reform process. JEL classification: P31, P23, P26 and J31.     

Swimming with the Tide: Solidary Wage Policy and the Gender Earnings Gap

This paper addresses the consequences of wage compression for the gender wage gap in Sweden during the period 1968–1991. We find that the effects of changes in the wage structure on women's wages have varied over time and have been partly counteracting. Changes in industry wage differentials have systematically worked against women, while changes in the returns to human capital and unobserved characteristics have contributed to reductions in the gender wage gap. Changes in the wage structure were particularly important between 1968 and 1974 when there was a dramatic reduction in overall wage inequality.

Gender earnings inequality in the service and manufacturing industries in the U.S.

This paper compares earnings inequality between women and men in a growing sector of the U.S. economy – the service sector, and a shrinking sector – manufacturing. We examine the hypothesis that deindustrialization will reduce inequality, and find that the absolute magnitude of the gender earnings gap is, in fact, smaller in the service sector. Decomposition analysis is used to partition the gender earnings gap into three parts: (1) earnings differences due to differences in mean characteristics – such as education and experience; (2) earnings differences due to preferential treatment of men; and (3) earnings differences due to disadvantageous treatment of women. The latter two constitute estimates of gender discrimination. The results of this study suggest that, ceteris paribus, deirndustrialization will likely reduce the gender gap in hourly earnings. However, this will come at the cost of lower earnings for both males and females, with the drop in earnings being particularly large for males. While deindustrialization is predicted to reduce the absolute magnitude of male-female earnings inequality, evidence suggests that gender discrimination will persist – discrimination explains about 60 percent of the gender wage gap in both the service and the manufacturing sectors.     

Decomposing the effect of trade on the gender wage gap

This paper uses variation in exposure to increased Chinese imports in Brazil to investigate the impact of trade on gender wage inequality. First, using Brazilian census data, we find that rising imports reduced the gender wage gap in Brazilian local labour markets. Next, using Oaxaca–Blinder decompositions, we show that this reduction in the wage gap was largely explained by trade increasing the share of female workers in higher-paying occupations. Finally, we use a matched employer–employee data set to investigate how individual workers adjust to the trade shock. Similar to the local labour market analysis, we find that male workers exposed to increased import competition saw a larger decline in both wages and cumulative earnings relative to female workers. In addition, we uncover an interesting asymmetry in that, while male workers exhibited much higher degrees of industry mobility in response to the trade shock, female workers exhibited an equal if not higher degree of occupational mobility.     

The unequal distribution of unequal pay – An empirical analysis of the gender wage gap in Switzerland

In this paper we analyze the distribution of the gender wage gap. Using microdata for Switzerland we estimate conditional wage distribution functions and find that the total wage gap and its discrimination component are not constant over the range of wages. At low wages an overproportional part of the wage gap is due to discrimination. In a further analysis of specific individuals we examine the wage gap at different quantiles and propose a new measure to assess equal earnings opportunities. These additional results reveal that it is primarily low education that causes the large discrimination component at low wages.

Male–female wage discrimination in Chinese industryInvestigation using firm‐level data1

We use firm‐level data to analyze male–female wage discrimination in China's industry. We find that there is a significant negative association between wages and the share of female workers in a firm's labour force. However, we also find that the marginal productivity of female workers is significantly lower than that of male workers. Comparing wage gaps and productivity gaps between men and women, we notice an intriguing contrast between state‐owned enterprises (SOEs) and private firms. The wage gap is smaller than the productivity gap in SOEs, while the converse is true for private firms. These results suggest that women in the state sector receive wage premiums, whereas women in the private sector face wage discrimination.
