Decomposing Gender Wage Differentials Using Quantile Regression: Evidence from the Lebanese Banking Sector

This paper investigates gender pay inequality in the labor market of a developing country. Our empirical investigation uses data derived from a sample of employees in the Lebanese banking sector for the years 2008 and 2014. Using Blinder-Oaxaca decomposition, the results reveal that the unexplained component of the gender wage gap, attributed to discrimination, represents a substantial share of the total gap. A surprising result is that the contribution of human capital to the gender wage gap is negative, suggesting that wage discrimination is the main explanation for the gap. Utilizing the Machado-Mata methodology to decompose the wage gap across the entire wage distribution, our findings indicate that the unexplained component of the raw gender wage gap is more pronounced at the low and middle ranges of the distribution. However, the explained component dominates at the top of the distribution, suggesting that earnings gaps are fully explained by observed characteristics.     

Wage differentials by sector and gender: a quantile analysis for the Spanish case

This paper analyses existing wage differentials between workers in the public and private sectors and by gender in Spain. This analysis is run throughout the entire earnings distribution and observed wage differentials are decomposed into a part explained by differences in productive characteristics and a part due to differences in returns to such characteristics. Our results show that public sector workers tend to earn higher wages than private employees, although most of this sector wage gap is due to better public workers’ productive characteristics. A wage premium in favour of men is also found in both the public and private sectors, with the gender wage gap greater at the top of the earnings distribution.     

Gender Wage Differentials and Occupational Segregation in Hong Kong, 1981–1996

This paper analyses gender wage differentials and the role of occupational segregation in Hong Kong. It is found that the female–male earnings ratio increased substantially from 0.710 in 1981 to 0.839 in 1996. A decomposition which takes into account occupational differences shows that the gender pay gap is mostly within occupations and most of the intra‐occupation wage gap is unexplained. The gender pay differential due to occupational differences is small; in fact, the overall occupational segregation favours females in Hong Kong.     

The evolution of male-female earnings differentials in Canadian universities,1970–2001

Abstract .  The evolution of academic salaries and the gender earnings gap in Canadian universities is analysed using a unique Statistics Canada data set containing detailed information on all full-time teachers at Canadian universities over the period 1970 through 2001. Male salaries declined across cohorts, while female salaries remained stable; consequently, male-female earnings differentials have narrowed. Recent years have also seen increasing variation in academic salaries for both men and women. A gender earnings gap remains, the bulk of which can be explained by differences in men's and women's rank and field. The unexplained earnings gap has decreased over time.     

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.     

金融发展与地区实体经济资本配置效率-来自省级工业行业数据的证据

职位隔离是形成性别收入差距的重要机制.本文构建一个引入了职位晋升机制的收入差距分解方法,利用2006年中国综合社会调查数据,考察了职位隔离对性别收入差距的作用,且在统一的模型框架内识别和估计了职位内工资歧视(同工不同酬)和晋升歧视的程度.研究结果发现,女性过多地集中于职位"金字塔"结构的底层.尽管职位晋升的工资效应不存在显著的性别差异,但约41%的性别收入差距是由于职位隔离导致的.工资歧视是职位层级内部性别收入差距的主要来源.与之类似,职位晋升歧视能够解释1/4的性别收入差距.因此,除了同工同酬政策,促进职位晋升的机会平等是缩小性别收入差距的重要措施,意即"同酬"还需"同工".     

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.     

Is There a Gap in the Gap? Regional Differences in the Gender Pay Gap

In this paper, we investigate regional differences in the gender pay gap both theoretically and empirically. Within a spatial model of monopsonistic competition, we show that more densely populated labour markets are more competitive and constrain employers’ ability to discriminate against women. Utilizing a large administrative data set for western Germany and a flexible semi‐parametric propensity score matching approach, we find that the unexplained gender pay gap for young workers is substantially lower in large metropolitan than in rural areas. This regional gap in the gap of roughly 10 percentage points remained surprisingly constant over the entire observation period of 30 years.     

REMOVING THE “VEIL OF IGNORANCE”: NONLINEARITIES IN EDUCATION EFFECTS ON GENDER WAGE INEQUALITIES

A large literature studies the mean gender wage gap in developing countries and finds mixed evidence about the role of education policies in closing gender earnings inequalities. We contribute to this literature by exploring two types of nonlinearities in wage earning regressions: (1) nonlinearities on the effects of education on expected earnings along the distribution of education endowments; and (2) heterogeneities on the contributions of education to the gender wage gap at different quantiles of the wage distribution. Our analyses provide new insights on how these nonlinear effects can be used to set up better targeted gender and development policies. (JEL I26, C14)     

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.     

The Gender Wealth Gap Across European Countries

This paper studies the gap in wealth between male and female single households using 2010 Household Finance and Consumption Survey data for eight European countries. In the raw data, a large gap emerges at the upper end of the unconditional distribution. While OLS estimates show no difference in average net wealth levels, quantile regressions at the 95th percentile yield mixed evidence for the gender wealth gap in different specifications. Labour market characteristics and participation in asset and debt categories largely explain the differences between male and female single households. The gender gap in net wealth is driven by gaps in gross wealth and its components, but is attenuated in four countries by gender gaps in (collateralized) debt. In the full specification, the unexplained gap in gross wealth amounts to 27 percent in Slovakia, 33 percent in France, 44 percent in Austria, 45 percent in Germany, and 48 percent in Greece.     

ARE COGNITIVE SKILLS RELEVANT IN GENDER EARNINGS DECOMPOSITIONS?

While cognitive skills are known to play an important role in labour market success, empirical evidence is mainly concentrated in its effect on returns to schooling. Evidence on the role of cognitive skills in gender earnings gap decompositions is virtually absent. I use two approaches to investigate the potential for cognitive skills to affect the size and pattern of the unexplained component of the earnings gap (‘relative discrimination’) across the wage distribution, using data from the International Adult Literacy Survey (IALS). It has been shown that when the raw cognitive score is used to control for cognitive skills, the return to schooling cognitive skills is generally underestimated. Once a distinction is made about the origins of cognitive skills (acquired in school versus outside the school), the returns to cognitive skills can vary depending on their origin. I find that using the raw score to control for cognitive skills does not result in any significantly different estimates of the unexplained component of the gap compared to when cognitive skills are not controlled for. However, once cognitive skills by origin of skill are used in place of total cognitive skills, the results change substantially for three of the five countries examined.     

The Economic Impacts of the COVID-19 Pandemic in Australia: A Closer Look at Gender Gaps in Employment,Earnings and Education

Three years into the COVID-19 pandemic, this article considers the longer-lasting economic impacts on the Australian workforce through a gender lens. Using Australian Bureau of Statistics data, it analyses changes in employment, earnings and educational participation relative to the pre-pandemic trends that were predicted to have otherwise occurred. Despite women's employment moving back towards pre-pandemic levels more rapidly than men's, the pandemic also saw a widening of the gender gap in earnings and a larger fall in women's educational participation. This paper highlights the need for ongoing monitoring of labour market indicators through a gender lens to inform more responsive policy design.     

The evolution of the returns to education and wage differentials in Brazil: a quantile approach

This paper uses quantile regression techniques to analyze the returns to education across the conditional distribution of wages from individuals separated both by gender and skin color, while accounting for the endogeneity of the education decisions. Using data from the Brazilian households survey (PNAD) for the years of 1988 and 1996, the results indicate that the returns to education are significantly heterogeneous across the distribution of earnings, as well as the wage gap between the groups, according to gender and skin color. Moreover, there has been a significant improvement in the wage differentials between the groups across the years.     

Panel estimates of the earnings gap in Norway: do female immigrants experience a double earnings penalty?

This study explores the possibility that being both a ‘female’ and an ‘immigrant’ will impose an earnings disadvantage on immigrant women in Norway. Well-known techniques are used to decompose the earnings gap between Norwegian men and immigrant women into portions attributable to productivity differentials, portions attributable to a gender effect, and portions attributable to an ethnic effect. The analysis supports the following conclusions: First, there is evidence of a double negative effect on female immigrant earnings. Second, gender effect is more important than ethnic effect. Finally, the discrimination estimates are robust to the alternative methods used in decomposing Norwegian men-immigrant women earnings gap.     

The effect of large‐scale privatization on public sector pay gap in a transition economy

Estimating the public–private sector earnings differentials in Serbia from 1995 until 2008 this paper finds significant changes at the mean and across the earnings distribution. The results show that the average public sector pay gap was negative at early stages of economic transition but grew to be positive during large‐scale privatizations. The paper uses different sources of data and adopts a number of statistical procedures, including a novel instrument to infer the likelihood of changes in the individual public sector status due to privatization.     

The Gender Wage Gap in Paid- and Self-Employment in Australia

This paper presents an analysis of the gender wage gap in the highly regulated Australian labour market. It compares wage outcomes in the wage and salary sector with those for the self-employed. Comparisons with the United States are provided. The large gender pay gap in self-employment suggests that the aggregate gender wage differential will not be eliminated solely through wage determination for wage and salary earners. The greater gender wage gap in the self-employed sector may reflect liquidity constraints that are more difficult for self-employed women to overcome relative to self-employed men. The comparisons with the United States suggest that women will experience deterioration in relative earnings as the Australian labour market is deregulated.     

Gender Earnings Differential in Urban China

This study uses survey data collected from five large cities in China to describe and decompose the earnings difference between female and male workers. The results indicate that the main source of lower earnings for females lies in unequal pay within sectors, and that the earnings gap due to differences in sectoral attainment is relatively small. The results also reveal that most of the gender earnings differential is attributable to sex discrimination rather than to the gender difference in the endowment of human capital. Therefore, eliminating discrimination against females within individual sectors is effective in narrowing the gender earnings gap.     

The use of quantile regressions in estimating gender wage differentials: a case study of the Philippines

Quantile regressions are used to analyse the size, components, and nature of the gender-earnings differentials as well as the returns to education by gender in the Philippines, over the entire conditional distribution of earnings, using data from the 1999 APIS survey. This approach allows more focused conclusions about the nature of gender-earnings differentials. Incorporating the quantile regression approach to the Oaxaca–Blinder decomposition allows the localization of gender discrimination to particular quantiles of the earnings distribution and permits more targeted policy intervention.     

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. First version received: April 1999/Final version accepted: July 2000
