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.     

The Role of Gender among Low-Paid and High-Paid Workers

Using data from the 2001 Australian Census of Population and Housing Household Sample File, this article analyses the gender wage gap across the wage distribution by using a quan‐tile regression approach. The results show that there is a much larger gender wage gap among high‐paid workers than there is among low‐paid workers. Moreover, this wage gap tends to increase reasonably uniformly when one is moving up through the wage distribution. Institutional factors, the work environment and social norms are all areas that may require attention in order to redress the undervaluation of women's skills.     

Sexual orientation and labour relations: new evidence from Athens,Greece

We use data from the 2008–2009 Athens Area Study (AAS) to provide the first evidence on the relationship between men's sexual orientation and wages in the Greek capital, Athens. Gay and bisexual men are found to receive significantly lower monthly wages than heterosexual male workers after accounting for demographic and occupational characteristics. The estimations reveal that educated gay and bisexual workers face lower wage differentials than less-educated gay and bisexual workers, which is consistent with the statistical theory of discrimination. However, wage gaps are significant at all educational attainment levels, suggesting that these workers face strong prejudices in the Athenian labour market. The same pattern holds also across all occupations and sectors. Furthermore, to better understand the determinants of the wage gaps, we compare gay/bisexual men with both married and unmarried heterosexual men. By making these comparisons, we are able to disentangle the penalty associated with being unmarried from other human-capital explanations for the wage gap.     

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.     

Are low-skill public sector workers really overpaid? A quasi-differenced panel data analysis

Public–private sectoral wage differentials have been studied extensively using quantile regression techniques. These typically find large public sector premiums at the bottom of the wage distribution. This may imply that low skill workers are ‘overpaid’, prompting concerns over efficiency. We note several other potential explanations for this result and explicitly test whether the premium varies with skill, using Australian data. We use a quasi-differenced Generalized Method of Moments (GMM) panel data model which has not been previously applied to this topic, internationally. Unlike other available methods, this technique identifies sectoral differences in returns to unobserved skill. It also facilitates a decomposition of the wage gap into components explained by differences in returns to all (observed and unobserved) skills and by differences in their stock. We find no evidence to suggest that the premium varies with skill. One interpretation is that the compressed wage profile of the public sector induces the best workers (on unobserved skills) to join the public sector in low wage occupations, vice versa in high wage occupations. We also estimate the average public sector premium to be 6% for women and statistically insignificant (4%) for men.     

The gender wage gap in Austria: eppur si muove!

We examine the change of the gender wage gap in Austria between 2002 and 2007 using Juhn et al. (Workers and their wages, AEI Press, Washington DC, pp 107–143, 1991) decomposition. We analyze data from Austrian tax records which we merge with social security records and Austrian micro-censuses of the years 2002 and 2007. We find that the gender wage gap declined from 21 % in 2002 to 18 % in 2007. The main determinant of this decline is the relative improvement of women’s unobserved characteristics. The decline of the gender wage gap is also due to women having attained more formal education and to a convergence of men’s and women’s returns to education. Women’s improved educational attainments were partly offset by a shift in the demand for skilled workers that disadvantaged unskilled workers, most of whom are women, resulting in a moderate decrease of the gender pay gap over these years. Robustness checks confirm our results.     

Economic transition and gender differentials in wages and productivity: Evidence from Chinese manufacturing enterprises

We use firm-level data to analyze male–female wage differences in Chinese industry in the late 1990s. Our estimates indicate that employers' discrimination against women was not a significant source of the gender wage gap in Chinese state-owned enterprises. Instead, we find that the relative wage of unskilled female to male workers was higher than their relative productivity. This result indicates that unskilled female workers in the state sector had historically received wage premiums and consequently accounted for a disproportionate share of the sector's labor surplus.     

Gender segregation and earnings differences in the Spanish labour market

This article analyses the effects of different types of gender segregation on the gender wage differential for the Spanish labour market. Matched employer–employee data from a sample of 226,535 workers are used. These workers are employed in 61 occupations within 26,492 establishments in 51 different industries. Workers belonging to the same industry, establishment or job share common factors which cannot be observed and these factors affect wages. If these unobservable variables are correlated with the explanatory variables, their estimated effects will be biased. For this reason, we estimate the effects of each type of gender segregation on the wage gap using a robust specification to these possible correlations. We obtain that industrial segregation by gender explains a lower part of the wage gap between men and women than previous researches found using standard regressions, while the contributions of establishment segregation and occupational segregation within each establishment are greater.     

Can U.S. Cities afford living wage programs? An examination of alternatives

Since 1994. so-called “living wage” ordinances have passed in 20 cities in the United States, and activists are advancing similar proposals throughout the country. These proposals are a response to the declining real wages of low-wage workers in the United States—what David Gordon termed “the wage squeeze” in Fat and Mean—and, in particular, to the 30 percent fall in the real value of the minimum wage from its peak in 1968. We consider here the main arguments advanced by opponents of living wage proposals: 1) they will place a heavy burden on municipal government budgets, forcing, among other things, cuts in vital city services that benefit low-income people; 2) they will encourage local businesses to relocate and discourage new businesses from investing within cities that have such ordinances; and 3) they will cause unemployment among low-wage workers. Examining these issues in the context of proposals that were either passed or considered in different cities, we find that none of the criticisms of living wage proposals stand up to careful scrutiny or evidence. Rather, living wage proposals are affordable and workable. They represent a small but significant step toward reversing the “wage squeeze” so carefully documented and analyzed in Fat and Mean.     

市场歧视对城镇地区性别工资差距的影响

本文使用基于分位数回归的反事实分析方法研究了中国城镇地区的性别工资差距问题,发现了以下三个结论:第一,性别工资差距在工资分布不同位置上存在不对称现象。从横截面数据来看,在工资分布顶端性别工资差距较小,在工资分布末端性别工资差距较大。从时序数据来看,在工资分布顶端性别工资差距越来越小,在工资分布末端性别工资差距越来越大。第二,性别工资差距在横截面数据上表现出不对称现象的原因是,女性在工资分布顶端受到的歧视程度低,在末端受到的歧视程度高。第三,性别工资差距在工资分布末端越来越大的原因是,女性受到的歧视程度越来越高;在工资分布顶端越来越小的原因是,男性和女性个人特征方面(如受教育水平)的差别越来越小。     

Trade Liberalization,Skill‐linked Intermediate Production and the Two‐sided Wage Gap

Abstract

A rising wage‐gap, almost universally, in the last two decades has contradicted the age‐old conventional wisdom of asymmetric wage movements across nations when trade is liberalized. We offer an explanation that fits well with the emerging trade pattern between the developed and more advanced developing countries like India and Mexico. We argue that a tariff reduction in the South on imports of an intermediate good from the North may raise the wage‐gap in both the North and the South. The price of the intermediate good moving in different directions and different factor‐intensity‐ranking of this good relative to the two different final goods produced in the two countries underlie this result. Rising wage inequality may specially affect the South because educational expenses and infrastructure do not allow ready transformation of the vast masses of unskilled workers into skilled workers. Hence, the policy lesson of the paper seems to be more public effort in arranging for smoother acquisition of human capital by the unskilled.     

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.     

Comparing earnings profiles in urban areas of an LDC: rural-to-urban migrants vs. native workers

"We use Tanzanian data to test a recently proposed hypothesis that rural-to-urban migrants have an incentive to supply greater work effort than native urban workers, because of the migrants' positive probability of returning to the low-wage rural areas. We treat the choice between public- and private-sector employment as endogenous and, for theoretical and empirical reasons, distinguish migrants with access to rural land from those without access. Our results show that migrants in both sectors face lower initial wage offers than native urban workers. But, the wage gap is eliminated within a decade or less, and thereafter, migrants surpass the wage offers of native workers."     

International Trade,Technology, and the Wage Gap: Evidence from Granger‐causality Tests*

In this paper, we propose an alternative approach under which to examine the source of the increased wage gap between skilled and unskilled workers in US manufacturing. Rather than imposing the assumptions inherent in a given structural form, we posit a long‐run equilibrium relationship between international trade, technology, and the wage premium using a vector error‐correction model. We first test for the existence of a long‐run relationship using cointegration tests. If a cointegrating relationship is found, we then conduct tests on the direction of the long‐run relationship and of Granger causality. We apply our approach to each two‐digit and four‐digit SIC industry and find evidence in support of international trade being an important source of the wage gap. Our results suggest that it is premature to dismiss international trade as a possible suspect behind the rising wage premium.     

Measuring the gender wage gap—a methodological note

ABSTRACT

We propose to estimate the Blinder-Oaxaca decomposition by a single-equation model augmented with interactions between the group membership and other predictors. The relative importance of predictors on the discriminatory wage gap is examined by the interaction coefficients, which may lead to very different conclusions than the usual percentage calculations using the detailed decomposition method. Comparisons are made between the traditional interpretations and those suggested here using wage data from Finland. The decomposition analysis suggests that the discriminatory male-female wage gap is largely related to work experience, while our preferred model points to the importance of family gap and working industry.     

THE PUBLIC SECTOR PAY GAP IN FRANCE, GREAT BRITAIN AND ITALY

We investigate public–private pay determination using French, British and Italian microdata. While traditional methods focus on parametric methods to estimate the public sector pay gap, in this paper, we use both non-parametric (kernel) and quantile regression methods to analyze the distribution of wages across sectors. We show that the public–private (hourly) wage differential is sensitive to the choice of quantile and that the pattern of premia varies with both gender and skill. In all countries the public sector is found to pay more to low skilled workers with respect to the private sector, whilst the reverse is true for high skilled workers. When comparing results across countries, we find that where pay formation is more regulated (i.e. as in France and Italy) the public sector pay gap is smaller; whilst where market factors play a larger role in pay determination (i.e. as in Great Britain) the public sector pay gap is larger—particularly in the lower part of the wage distribution—and females are much better off in the public sector as compared to the private sector.     

Gender wage differentials by education in Italy

In this article we evaluate wage differentials in Italy combining gender and education perspectives. The main goal of this article is to verify whether the extent of the gender pay gap varies between highly- and low-educated workers, and whether or not the role played by gender differences in characteristics and in market rewards is similar in the two groups. We apply quantile regression analysis and an adaptation of the procedure suggested by Machado and Mata (2005) to evaluate the predicted wage gap at different points of the female wage distribution scale. The analysis is carried out on the Italian sample of the last available year of the European Community Household Panel (ECHP). We show that the extent and the trend of the gap predicted across the female distribution is sharply different between groups with diverse educational levels. In the case of low-educated workers, although the predicted gap is largely explained by differences in rewards, lower levels of education or experience are responsible for the gap, especially on the right-hand side of the distribution. On the contrary, highly-educated females have better characteristics than highly-educated men that partially compensate the rather high difference in returns, in particular at the extremes of the distribution.     

The changing employment situation in some cities with living wage ordinances

More than 120 municipalities (cities, towns, and counties) have introduced living wage ordinances. These laws mandate that certain employers in their jurisdiction pay their workers wages that are above federal and state minimum levels. The opponents of these laws argue that these ordinances have adverse impacts on local labor markets. This study considers rates of growth of employment and unemployment trends in a sample of these cities before and after they introduced their living wage ordinances. It finds that while a few cities have had negative labor market experiences after introducing their living wage law these cities represent the exception rather than the rule.     

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.     

Wage Bargaining Versus Efficiency Wages: A Synthesis

We construct a model integrating the efficiency wage model of Shapiro–Stiglitz (1984) (SS), with an individual wage bargaining model in the Diamond–Mortensen–Pissarides (DMP) tradition where firms and workers form pairwise matches. We show that when workers may threaten to shirk on the job and there is individual wage bargaining, the wage is always higher and employment lower than in either the SS model, or the (appropriately modified) DMP model. When firms determine workers' efforts unilaterally, efforts are set inefficiently low in the SS model. In the bargaining model, effort is higher, and is first best when the worker non–shirking constraint does not bind. The overall equilibrium allocation may then be more or less efficient than in the SS model, but is always less efficient than in a pure bargaining model with no moral hazard.
