Public Sector Employment,Wage Inequality and the Gender Pay Ratio in the UK

This paper assesses the relative contributions of the different systems of pay determination in the private sector and the public sector toward the changing level of wage inequality and the gender pay ratio in the UK. The greater centralisation of pay arrangements in the public sector compared with the private sector in the UK suggests that public sector employment may have acted to offset the widening wage inequality seen in recent years, as well as making an important contribution to the increase in women's relative average earnings compared to men. This issue is addressed by drawing on unpublished occupational hourly earnings data from the New Earnings Survey and applying decomposition of the Theil index of wage inequality to analyse both static and dynamic trends. The change in wage inequality for the period 1986 to 1995 primarily reflected the change in wage dispersion within the private sector, and the narrowing of the gender pay gap among the public sector workforce was an important factor in explaining the overall improvement in women's relative earnings. The paper argues that the relatively centralised pay arrangements in the public sector, compared with the private sector, played an important role in slowing the increase in wage inequality and narrowing the gender pay gap. As such, future policies to decentralise pay determination in the UK public sector may exacerbate the increasing level of wage inequality and reverse women's recent relative pay improvements.     

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.     

Understanding the gender wage-gap differential between the public and private sectors in Italy: A quantile approach

This paper analyzes the gender-based wage gaps across the wage distribution in the private and public sectors in Italy for the years 2005–2010. We use quantile regression methods to estimate and decompose the wage gap at all wage levels and propose a two-step procedure that relies on a novel approach to estimating fixed effects quantile regressions. The method's main advantage is that it allows the employment sector's marginal effect on wages at various points of the distribution to be estimated, while accounting for both observable and time-invariant unobservable factors. The new method stresses important differences with respect to standard decomposition analyses and amplifies the differences in the two sectors' wage-setting mechanisms. When the estimation is net of individual heterogeneity, the gender-based wage gap decreases in both sectors and there is evidence of a glass ceiling effect, but only in the public sector. Economic grounds are provided.     

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.     

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.     

Glass Ceiling or Sticky Floor? Exploring the Australian Gender Pay Gap

Using the Household, Income and Labour Dynamics in Australia survey, this paper analyses the gender wage gaps across the wage distribution in both the public and private sectors in Australia. Quantile regression techniques are used to control for various characteristics at different points of the wage distributions. Counterfactual decomposition analysis, adjusted for the quantile regression framework, is used to examine if the gap is attributed to gender differences in characteristics, or to the differing returns between genders. The main finding is that a strong glass ceiling effect is detected only in the private sector. A second finding is that the acceleration in the gender gap across the distribution does not vanish even after account is taken of an extensive set of statistical controls. This suggests that the observed wage gap is a result of differences in returns to genders. By focusing only on the mean gender wage gap, substantial variations of the gap will be hidden.     

A note on schooling and wage inequality in the public and private sector

The few studies that have examined the wage impact of education across the earning distribution have focused on high-income countries and show education to be more profitable at the top of the distribution. The implication is that education may increase inequality. Extending the analysis to 16 East Asian and Latin American countries, in Latin America we observe a pattern similar to that of Europe/North America (increasing wage effects), while in East Asia the wage effects are predominantly decreasing by earnings quantile. However, once the analysis is performed separately for the public and the private sector, it is revealed that the strongly decreasing impact of schooling on earnings in the public sectors of East Asian countries is responsible for the overall observed decreasing pattern, while the impact of schooling on earnings in the private sectors of these countries is non-decreasing.     

Labour market institutions,crisis and gender earnings gap in Eastern Europe

We study gender pay inequality in ten Central and Eastern EU countries before (2007) and during the economic crisis (2009) using quantile regression methods. The analysis reveals remarkable cross‐country diversity in levels and patterns of the gender gap along the earnings distribution; for the majority of the countries the crisis is associated with declining male/female disparities. We address the role played by labour market institutions in shaping the observed gender pay gap levels and patterns. Labour market deregulation increases gender inequality at the middle and at the top of the pay distribution, but reduces disparities at the bottom. Higher union density and wage coordination reduce the pay gap, with stronger equalizing effects on better‐paid jobs. The crisis seems to weaken the already poor role of institutions in the low‐pay sector.     

Wage differentials and state‐private sector employment choice in Yugoslavia*

In this study we use the newly available Yugoslavian Labor Force Survey data to investigate wage differentials and employment decisions in the state and private sectors in Yugoslavia. For the analysis we use three empirical models that rely on different statistical assumptions. We extend the standard switching regression model to allow non‐normality in the joint distribution of the error terms. After correcting for the sector selection bias and controlling for workers’ characteristics we find a private sector wage advantage. The wage premium is largest for workers with low education levels and declining for workers with higher educational levels. Given the regulatory and tax policies that pushed the private sector into the informal sphere of the economy during the period covered by our data, we argue that the state/private wage gap is likely to grow in the future. This will make it increasingly difficult for the state sector to attract and retain highly skilled employees.     

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.     

Segregation and gender wage gaps in the private and the public sectors: an analysis of Danish linked employer–employee data, 2002–2012

This paper examines the relation between segregation and the gender wage gap in the public and the private sectors in Denmark from 2002 to 2012. The analysis shows that male–female differences in the share of females in occupations, industries, establishments and job cells (occupations within establishments) constitute 46 % of the raw gender wage gap in the private sector, while segregation in the public sector accounts for as much as 63 %. Segregation thus plays a substantially more important role in accounting for the gender wage gap in the public sector than in the private sector. While the importance of segregation for wage formation decreased substantially in the public sector over time, it only decreased slightly in the private sector. Although the remaining gender wage gap, after controlling for segregation, is close to zero in the public sector, a substantial within-job cell differential remains after controlling for segregation in the private sector.     

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.     

Intra‐industry Trade Liberalization: Why Skilled Workers are More Likely to Support Free Trade

This paper presents a theoretical model and empirical analysis that connects the prevalence of intra‐industry trade with increased wage inequality from trade liberalization in both skilled and unskilled labor abundant countries. The Stolper–Samuelson effect is incorporated into an intra‐industry trade liberalization (intra‐ITL) hypothesis where skilled labor opposes protectionism in all countries engaged in intra‐industry trade because skilled workers gain at the expense of unskilled workers from multilateral trade liberalization within the skill‐intensive sector. We examine empirical evidence on whether skilled individuals are more supportive of trade liberalization than unskilled individuals across 31 countries with different levels of intra‐industry trade and skill endowments. We find that the extent to which countries engage in intra‐industry trade in high‐tech commodities is strongly linked with the intensity of opposition to protection by skilled labor. Regression results strongly support our hypothesis that skilled workers, almost everywhere, are more likely to support free trade.     

Employment shifts, economic reform and the changes in public/private sector wages in Mexico: 1987–1997

Over the last decade, the public sector in Mexico experienced substantial fiscal reform, divestiture of public enterprises, and the elimination of many regulations affecting pay and employment. This study analyzes the changes in the public/private sector differences in wages during the 1987–1997 period. The results from analyzing microdata from the Encuesta Nacional de Empleo Urbano show that relative public sector wages increased from 1987 to 1997. Most of the relative wage increase in the public sector can be explained by increases in the price of skills and by changes in sorting across sectors. The results have important public policy implications since they suggest that public sector workers earn more and their wages have grown faster than those of their private sector counterparts. As such, policies contemplating public sector reform should take into account the effect of these measures on the inter-sectoral income distribution and the overall economic growth.

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.     

Public sector motivation and development failures

This paper provides a theoretical analysis of the relationship between public sector motivation and development. In the model the public sector produces a public good and workers are heterogeneous in terms of public sector motivation (PSM). Wages in the private sector increase with the quality of the public good. In this context, public sector wage premia (PSWP) have two opposite effects: low PSWP helps screen workers with PSM into the public sector, while high PSWP helps motivate workers to be honest. Raising PSWP may not improve the quality of governance and multiple equilibria might arise. The model highlights that the relative importance of workers selection and provision of ”on the job” incentives in the public sector varies in systematic ways with wages in the private sector. We provide anecdotal and original empirical evidence consistent with the theoretical predictions and discuss some policy implications for public sector reforms in developing countries.     

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.     

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.     

The establishment-size wage premium: evidence from European countries

This study examines the magnitude and determinants of the establishment-size wage premium in five European countries using a unique harmonised matched employer–employee data set (the 1995 European Structure of Earnings Survey). This data set enables to test the validity of various traditional explanations of the size wage gap (i.e. the labour quality hypothesis, the theory of compensating wage differentials, the role of monitoring and institutions) and of more recent hypotheses (i.e. size differences in job stability and in the concentration of skilled workers). We find some support for traditional explanations, but there remains a significant wage premium for workers employed in large establishments. Further results indicate that the magnitude of this premium fluctuates substantially across countries and appears to be negatively correlated with the degree of corporatism.     

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.
