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.     

Public–Private Sector Wage Differentials in Australia

This paper examines public–private sector wage differentials in Australia. After controlling for observed characteristics and individual fixed effects, we show that on average workers in the public sector earn about 5.1 per cent more in hourly wages than those in the private sector. The wage premium is slightly higher for females than males. Using a panel data quantile regression model with fixed effects, we show that the positive wage effects of public sector employment are heterogeneous, with comparatively larger impact at the lower end of the wage distribution than at other parts. We also find evidence of heterogeneity in the public sector wage premiums by qualification, time period, occupation and state/territory.     

The wage effects of training in Portugal: differences across skill groups,genders, sectors and training types

This article investigates the determinants and wage effects of training in Portugal. In a first stage, we show that there are considerable differences in training participation across groups of workers, with elder and low educated individuals participating substantially less. In a second stage, we show that training has a positive and significant impact on wages. The estimated wage return is about 30% for men and 38% for women. Discriminating between levels of education and working experience and the public and private sector reveals important differences across categories of workers. We find that women, low educated workers and workers with long working experience earn larger returns from training. The average effect of training is similar in the private sector and the public sector. However, differences across experience groups are larger in the private sector, while differences across education groups are larger in the public sector. We use three alternative classifications of training activities and find that training in the firm, training aimed to improve skills needed at the current job and training with duration less than a year are associated to larger wage gains.     

HETEROGENEITY AND THE PUBLIC SECTOR WAGE POLICY

A model with search and matching frictions and heterogeneous workers was established to evaluate a reform of the public sector wage policy in steady state. The model was calibrated to the U.K. economy based on Labour Force Survey data. A review of the pay received by all public sector workers to align the distribution of wages with the private sector reduces steady‐state unemployment by 1.4 percentage points.     

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.     

Firm ownership and internal labour practices in a transition economy

One feature common to many post‐socialist transition economies is a relatively compressed wage structure in the state‐owned sector. We conjecture that this compressed wage structure creates weak incentives for work effort and worker skill acquisition and thus presents adverse consequences for the entire transition economy if a substantial portion of the labour force works in the state sector. We explore firm wage incentives and worker training, as well as other labour practices and outcomes, in a transition setting with matched firm and worker data collected in one of the largest provinces of Vietnam – Ho Chi Minh City. The Vietnamese state sector exhibits a compressed wage distribution in relation to privately owned firms with foreign ownership. State wage practices stress tenure over worker productivity and their wage policies result in flatter wage–experience profiles and lower returns to education. The state work force is in greater need of formal training, a need that is in part met through direct government financing. In spite of the opportunities for government financed training and at least partly due to inefficient worker incentives, state firms, by certain measures, exhibit lower levels of labour productivity. The private sector comparison group to state firms for all of these findings is foreign owned firms. The internal labour practices of foreign firms are more consistent with a view of profit‐maximizing firms operating with no political constraints. This is not the case for Vietnamese de novo private firms that exhibit much more idiosyncratic behaviour and whose labour practices are often indistinguishable from state firms. The exact reasons for this remain a topic of on‐going research yet we conjecture that various private sector constraints, including limited access to formal capital, play an important role.     

Is the Swedish central government a wage leader?

Is the Swedish central government a wage leader? This question is studied empirically in a vector error-correction model using a unique, high quality data set. It is first shown that salaries of white-collar workers in the private sector and central government are cointegrated. It is then found that private sector salaries are weakly exogenous to the system of equations. This means that the private sector is the wage leader in the long-run model. It is also found that changes in central government salaries do not Granger cause changes in private sector salaries. Together, these findings clearly demonstrate that the central government is not placing undue pressure on salaries in the private sector. The central government is not acting as a wage leader.     

Earnings Differentials between State and Non-State Enterprises in Urban China

The present paper estimates earnings differentials between state and non-state sectors for Chinese urban residents in 1996 by taking into account differences in non-wage benefits. Household survey data are used to estimate wage differentials while aggregate statistics are utilised in estimating non-wage benefits. We find that state-sector workers earned significantly more than workers in urban collective and domestic private enterprises in 1996. Unskilled workers in foreign invested enterprises (FIE) earned significantly less than those in the state sector but skilled workers earned more in FIE than in the state sector. These findings shed light on the source of labour immobility that state-owned enterprise had experienced until recently.     

Unions and wage inequality: The roles of gender,skill and public sector employment

We examine the changing relationship between unionization and wage inequality in Canada and the United States. Our study is motivated by profound recent changes in the composition of the unionized workforce. Historically, union jobs were concentrated among low-skilled men in private sector industries. With the steady decline in private sector unionization and rising influence in the public sector, half of unionized workers are now in the public sector. Accompanying these changes was a remarkable rise in the share of women among unionized workers. Currently, approximately half of unionized employees in North America are women. While early studies of unions and inequality focused on males, recent studies find that unions reduce wage inequality among men but not among women. In both countries, we find striking differences between the private and public sectors in the effects of unionization on wage inequality. At present, unions reduce economy-wide wage inequality by less than 10%. However, union impacts on wage inequality are much larger in the public sector. Once we disaggregate by sector, the effects of unions on male and female wage inequality no longer differ. The key differences in union impacts are between the public and private sectors—not between males and females.     

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.     

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.     

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.     

Evolution of the Public–Private Sector Wage Differential during Transition in Estonia

This article estimates the public–private sector wage differential in Estonia over the transition period. Quantile regression is used with a dataset from Estonian Labour Force Surveys from 1989 to 2004 for this purpose. The results of the analysis indicate that the public–private sector wage differential was negative during early transition but has decreased subsequently. It also shows that employees with low potential wages tend to gain more or lose less from working in the public sector than workers with high potential wages. The public–private sector wage differential is negatively related to the number of public employees and tends to be counter-cyclical. Political cycles have no effect on the public–private sector wage differential in Estonia.     

New evidence on public sector wage differentials

This paper examines the nature of wage differentials for men and women in the public sector, using a sample selection approach. This includes the self-selection that occurs in the sectoral choice process as well as the selection that arises in context of the labour force participation decision of men and women. Using 1991 Current population Survey data, it is found that male workers in the public sector on an average earn higher wages than male private sector workers, whereas the wage premium earned by women is undermined by a slightly greater degree of discrimination in the public sector     

GOVERNMENT‐MANDATED DISCRIMINATORY POLICIES: THEORY AND EVIDENCE*

We study an economy with private and public sectors in which workers invest in imperfectly observable skills that are important to the private sector but not to the public sector. Government regulation allows native majority workers to be employed in the public sector with positive probability while excluding the minority from it. We show that even when the public sector offers the highest wage rate, it is still possible that the discriminated group is, on average, economically more successful. The widening Chinese/Malay wage gap in Malaysia since the adoption of its New Economic Policy in 1970 supports our model.     

Wage Differentials between the State and Private Sectors in Moscow

In this study the 1997 Russian Labor Force Survey is used to investigate wage differentials between the state and the private sector in the city of Moscow. Our analysis demonstrates that substantial differences exist between private and state sector wages. We estimate the gap between private and state sector wages to be 14.3 percent for men and 18.3 percent for women. We also find gender differences in wages. Men in the private sector earn on average 23.7 percent more than women. The gender wage gap in the state sector is even higher at 32.5 percent. In the state sector, wages for both men and women increase as years of tenure increase. But in the private sector this is only true for men; women earn no return to tenure. The probability of employment in the private sector decreases with age and tenure.     

Screening and Human Capital in the Australian Labour Market of the 1990s

This paper presents tests of the screening hypothesis using data on adult males from the 1996 Australian Census of Population and Housing. These tests are based on comparisons of wage and salary earners and the self-employed, and public and private sector workers, as examples of screened and unscreened employments. The first test compares the mean levels of schooling, income and labour market experience in screened and unscreened sectors, while the second examines the returns to schooling and the goodness of fit of the earnings models for both wage and salary earning (separated into public and private sector employees) and self-employed groups. The results are equivocal, but suggest screening could be part of the earnings determination process in the Australian labour market.     

Government employment and the provision of fringe benefits

This study uses individual level data from the United States to examine the influence of government employment on the provision of five major fringe benefits. Four of the five benefits are more likely to be provided to government workers than to their private sector counterparts. Unlike wage comparisons which typically find substantial overpayment only for federal workers, the findings suggest that past wage differentials underestimate the true compensation advantage enjoyed by government workers.     

劳动力市场的所有制分割与城乡收入差距

目前缺少系统的农民工工资的面板数据妨碍了对城镇劳动力市场的所有制分割如何影响城乡收入差距的研究。本文证明城镇集体经济部门的平均工资可以作为农民工工资的代理变量,并将城镇国有部门的平均工资与集体部门的平均工资的比例作为衡量城镇劳动力市场所有制分割的指标。笔者通过对中国1978—2008年间省际面板数据的回归分析发现,劳动力市场的所有制分割本身具有扩大城乡收入差距的效应,但是,非国有部门职工比重的增加会削弱所有制分割的影响,从而有助于缩小城乡收入差距。     

Informality,public employment and employment protection in developing countries

This paper proposes an equilibrium matching model for developing countries’ labor markets where the interaction between public, formal private and informal private sectors are taken into account. Theoretical analysis shows that gains from reforms aiming at liberalizing formal labor markets can be annulled by shifts in the public sector employment and wage policies. Since the public sector accounts for a substantial share of employment in developing countries, this approach is crucial to understand the main labor market outcomes of such economies. Wages offered by the public sector increase the outside option value of the workers during the bargaining processes in the formal and informal sectors. It becomes more profitable for workers to search on-the-job, in order to move to these more attractive and more stable types of jobs. The public sector therefore acts as an additional tax for the formal private firms. Using data on workers’ flows from Egypt, we show empirically and theoretically that the liberalization of labor markets plays against informal employment by increasing the profitability, and hence job creations, of formal jobs. The latter effect is however dampened or even sometimes nullified by the increase of the offered wages in the public sector observed at the same time.
