Increased sorting and wage inequality in the Czech Republic

This paper makes use of a linked employer–employee dataset to examine the evolution of wage inequality in the Czech Republic during 1998–2006. We find evidence of slightly increasing returns to human capital and diminishing gender inequality and document sharp increases in both within‐firm and between‐firm inequality. We investigate several hypotheses to explain these patterns: increased domestic and international competition, decentralized wage bargaining, skill‐biased technological change and a changing educational composition of the workforce. Domestic competition is found to lower within‐firm inequality whereas we find no evidence that increased international trade at the industry level is associated with higher between‐ or within‐firm wage inequality. The key factors driving the observed increase in wage inequality are increased educational sorting and the inflow of foreign firms to the Czech Republic.     

The gender difference in wages and the returns to schooling over the great recession in the U.S.

This paper examines the effects of the Great Recession on the gender difference in hourly wage and the rate of return to schooling in the United States. Using data from American Community Survey 2000–2015, we find that the male-female difference in hourly wage declined during and after the recession. The Great Recession decreased earnings for both men and women, especially for those with more education. We also find there is a significant gender difference in the effects of the Great Recession on the returns to schooling. The Great Recession increased the rate of return to schooling for both men and women, and the female-male difference in the returns to schooling decreased by 0.4 percentage points in the post-recession period. The change of the gender difference in the returns to schooling can be explained by the wage structure change for men and women over the recession.     

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.

Bayesian Unconditional Quantile Regression: An Analysis of Recent Expansions in Wage Structure and Earnings Inequality in the US 1992–2009

We develop Bayesian inference for an unconditional quantile regression model. Our approach provides better estimates in the upper tail of the wage distribution as well as valid small sample confidence intervals for the Oaxaca–Blinder decomposition. We analyze the recent changes in the US wage structure using data from the CPS Outgoing Rotation Group from 1992 to 2009. We find that the largest part of the recent changes is explained mainly by differences in returns to education while the decline in the unionization rate has a small impact, and that earnings inequality is rising more at the top end of the wage distribution.     

Changes in the Austrian structure of wages, 1996–2002: evidence from linked employer-employee data

Analyzing data from the Structure of Earnings Surveys we find that wage dispersion in Austria increased only marginally between 1996 and 2002. There was an increase in the returns to education which accrued only to male workers. The positive effects of tenure and especially of experience on wages decreased over time. We adopt the Machado–Mata (J Appl Econ 20:445–465, 2005) counterfactual decomposition technique which allows to attribute changes in each wage decile to changes in worker and workplace characteristics and into changes in returns to these characteristics. Behind the small net increase in inequality we document a number of interesting gross effects that influence the change in the wage distribution. We find that both composition effects due to gender, education and age and market-driven effects such as changes in returns and changing workplace characteristics contributed to a higher dispersion of wages.     

Earning functions in Portugal 1982–1994: Evidence from quantile regressions

This paper uses quantile regressions to describe the conditional wage distribution in Portugal and its evolution over the 1980s as well as the implications for increased wage inequality. We find that, although returns to schooling are positive at all quantiles, education is relatively more valued for highly paid jobs. Consequently, schooling has a positive impact on wage inequality. Moreover, this tendency has sharpened over the period. We also find that most of the estimated change in wage inequality was due to changes in the distribution of the worker's attributes, rather than to increased inequality within a particular type of worker. this version: January 2000     

Educational Attainment and the Gender Wage Gap: A Comparison of Young Men and Women in 1984 and 2007

This study pools data from two sources to investigate the role of educational attainment in determining the gender wage gap. The empirical analysis reveals that the returns to education remained largely unchanged for young men but declined significantly for young women over the period 1984–2007. We find significant evidence of a decline in the returns to a Bachelor's degree for young women as well as evidence of increasing wage inequality over time among young men and women with a Bachelor's degree. Also, in 2007, the gender wage gap between young men and women was largest for those with a Bachelor's degree. Further, our analysis suggests that young women with a college education may confront more discrimination in the labor market than young women without a college education. We conclude that promoting educational attainment among young women may be a necessary but not sufficient condition for addressing the gender wage gap.     

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.     

Declining Returns to Education in Norway? Comparing Estimates across Cohorts,Sectors and over Time

We examine the role of the Norwegian education system in explaining the moderate and stable earnings dispersion in Norway. Estimating earnings equations for 1980 and 1990, we find that returns to education have been remarkably stable in Norway, also when we compare returns to education across different sectors of the economy. Our analysis controls for self-selection into education by using an instrumental variable technique. We estimate separate education earnings profiles for different cohorts to identify the effect on wage premiums of the large changes that have taken place in the Norwegian education system. The substantially higher level of educational attainment for more recent cohorts does not, cet. par. , seem to have a negative effect on educational wage premiums for these younger cohorts.

Privatization,FDI inflow and economic growth: evidence from China's provinces, 1978–2008

China's economic growth over 1978–2008 is a miracle. This article attempts to figure out and quantify the factors leading to this miracle. It is generally believed that economic reform and opening up is the key to China's economic success, but that is far from being exact and specific. This study hypothesizes that privatization and Foreign Direct Investment (FDI) inflow are the two key factors in this process. We focus on identifying the exact, specific and detailed mechanisms of privatization and FDI inflow in promoting economic growth, especially from the provincial level. Then using a panel data covering 31 provinces of Chinese mainland over 1978–2008, we find statistically significant evidence to support our hypotheses. We predict that further economic growth depends on further privatization and opening up, that is, depends on denationalization of the economy.     

The gender wage gap among China’s rural–urban migrants

In this study, we present new empirical evidence on gender wage differences among rural–urban migrants in China. We use a data set that includes migrants residing in urban communities and those living at their workplaces—the latter were not included in the previous studies. We find that the gender wage gap among migrants is 16%–18% and does not differ between migrants living at workplaces and those living in urban communities. However, gender differences in industry sorting play a more important role for migrants living at their workplaces, whereas differences in education and experience are of importance for those living in urban communities. Overall, differences in the returns to characteristics are the main driver of the gender wage gap, especially for migrants living in urban communities.     

Training,productivity and wages: An investigation of China's manufacturing enterprises in a privatization era

We estimated a structural model of production and wage determination in which labour quality can be affected by a firm's training decision using data of China's manufacturing enterprises in an era of privatization (2004–2007). Training increased both productivity and wages, but the former increased more, which explained the voluntary provision of on-the-job training. Our results also indicate that state-controlled enterprises' investment in training could be both privately and socially efficient; unions played a role in promoting training; it might be more privately and socially efficient for manufacturing firms to prioritize training resources to lower-educated, female and junior workers, if they had not done so, during privatization.     

Wage distribution in Japan, 1989–2003

Abstract. This study examines the recent trend of the Japanese wage distribution based on a micro‐level data set from the Basic Survey on Wage Structure (1989–2003). We perform several decomposition analyses of changes in the distribution of the hourly wage. We observe that lower returns to education and years of tenure contribute to a diminishing income disparity between groups for both sexes. A larger variance within a group contributes to the wage disparity for males, while an increased heterogeneity of workers' attributes contributes to the wage disparity for females. The Dinardo, Fortin, and Lemieux decomposition confirms the basic findings with a parametric variance decomposition.

PRIVATIZATION IN CHINA: TECHNOLOGY AND GENDER IN THE MANUFACTURING SECTOR

This paper examines the impact of privatization on gender discrimination in China across firms with different technology intensities. Using a comprehensive firm‐level survey, the paper identifies gender wage‐productivity differentials by directly estimating the relative productivity levels of workers from the production function of firms. The panel structure of the survey is taken advantage of by following firms that were fully state‐owned in the initial year, and distinguishing them from firms that were later privatized. The main results show that privatization was associated with an increase in relative productivity of female workers in high technology industries, and a reduction in relative productivity of female workers in low technology industries. Time varying coefficient results suggest that the improvements in gender outcomes in high technology industries may not be maintained in the long run as the relative wage and productivity ratios tend to deteriorate, potentially due to low supply of highly educated female workers. At the same time, outcomes in privatized low technology industries increase over time, lowering the wage and productivity gaps between male and female workers. (JEL J16, J31, P20)     

The combination of two tragedies: commons and anticommons tragedies

This paper studies the relationship between social conflict and skilled–unskilled wage inequality through the three-sector general equilibrium approach. In the basic model without the urban unskilled minimum wage, we find that when the government enhances the degree of controlling social conflict, the skilled–unskilled wage inequality will be narrowed down (resp. widened) if the urban skilled sector is more capital intensive (resp. labor intensive) than the urban unskilled sector. The extended models address the issue under different economic structures or different types of social conflict. In the extended model with the urban unskilled minimum wage, we find that the skilled–unskilled inequality will be widened when the degree of controlling social conflict is increased. In other extended models, we find that the above obtained results are still robust.     

OCCUPATIONAL SPECIFICITY OF HUMAN CAPITAL*

We find that returns to occupational tenure are substantial. Everything else being constant, 5 years of occupational tenure are associated with an increase in wages of 12%–20%. Moreover, when occupational experience is taken into account, tenure with an industry or employer has relatively little importance in accounting for the wage one receives. This finding is consistent with human capital being occupation specific.     

POLITICAL SELECTION OF FIRMS INTO PRIVATIZATION PROGRAMS. EVIDENCE FROM ROMANIAN COMPREHENSIVE DATA

Exploiting a unique institutional feature of early Romanian privatization, when a group of firms was explicitly barred from privatization and another was partially privatized by management–employee buyouts, we test how politicians select firms into privatization programs. Using comprehensive firm data, we estimate the relation between preprivatization firm characteristics – the information known to politicians at the time of decision‐making – and the effect of privatization on employment, efficiency, and wages. With the estimated coefficients we simulate the effect of privatization on non‐privatizable and privatizable firms. We find that politicians expected privatization to increase employment in the privatizable group by 7%–10%, while to decrease it in the non‐privatizable group by 10%–30%, depending on the first‐stage estimation method, ordinary least squares with or without matching. We do not find such discrepancies in the expected change in firm efficiency; the simulated efficiency effect of privatization is large and positive for both groups of firms, and it is 52%–65% for non‐privatizable and 41%–43% for privatizable firms. The analysis does not support the hypothesis that wages played an important role in privatization decisions. Our study suggests that employment concerns played the key role in selecting firms for privatization, even if efficiency gains had to be sacrificed.     

Wage inequality in a developing country: decrease in minimum wage or increase in education returns

In this paper we analyze the increase in wage inequality observed in the Uruguayan labour market during the last decade, by studying how the changes in minimum wage and returns to education affected the wage structure. Although in most developed countries a significant proportion of the increase in wage inequality is explained by a fall in the real minimum wage, this is not the case for the Uruguayan labour market. We observe that returns to education increased significantly, which could explain the increase of wage dispersion by its effects on the upper tail of the wage distribution. To derive these conclusions we follow a parametric and nonparametric quantile regression approach.     

Self-Employment and Wage Earning in Hungary

This paper examines the earnings determinants of the self‐employed and wage earners in Hungary in the mid‐1990s, taking into account two forms of selection: selection into working or non‐working for every individual in its sample and selection into self‐employment or wage‐earning jobs for workers only. Previous studies use switching regression to examine the returns to individual characteristics, taking into account only selection into self‐employment or wage‐earning jobs. The authors find that the estimated returns to individual characteristics when accounting for both forms of selection, differ from estimates correcting for only selection into self‐employment or wage‐earning jobs. They also find that the earnings determinants of the two sectors are not significantly different from each other.
