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.     

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.     

The Ddeterminants of Individual Wages in Australia: Competitive and Non-Competitive Influences

This work provides a test of competitive theories of wage determination by examining the wages of identical workers across industry classifications. The finding that a set of significant industry wage differentials exists would seem to contradict a purely competitive theory of wage determination. However, the apparent presence of unmeasured human capital that is correlated with industry status does provide one potential competitive explanation for the industry wage effects. Moreover, non-competitive explanations for the differences in industry wages, such as efficiency wage theory or institutional factors, appear to be inconsistent with the nature of the wage differentials.     

Decomposing the German East–West wage gap

Wages in East Germany are persistently lower than in West Germany. We study the micro‐level determinants of this spatial wage gap, using an Oaxaca–Blinder decomposition and rich linked employer–employee data. In total, up to one half of the aggregate wage differential can be attributed to structural differences in worker, establishment and regional characteristics. Regional price and establishment size differentials alone account for one quarter of the wage gap at the median. Price level differentials are even more relevant towards the top of the wage distribution. Towards the bottom, differences in union coverage become more important. Our findings are quite stable over the period from 1996 to 2010.     

工作特征对性别工资差距的作用

补偿性工资是解释性别工资差距的理论之一。本文利用2006年中国综合社会调查(CGSS2006)数据同时考察了人力资本和工作特征的工资效应,并采用Jann(2008)提出的无歧视工资机制的估计方法,对性别工资差距进行了分解分析。研究发现,我国城镇劳动力市场两性的工作特征存在显著的差异,但部分工作特征对工资的作用方向并不符合补偿性工资理论的预期。管理职务上的差异对性别工资差距具有一定的解释作用,但加入大量的工作特征变量后,性别工资差距中总的可解释部分没有明显提高。由此推论,性别歧视可能是形成工资差距的重要因素。促进性别平等和妇女发展必须采取更加积极的公共政策和反歧视措施。     

工资差异分解方法述评

工资差异分解方法发展到今天,可谓均值分解和分布分解共分其天下.均值分解方法呈Oaxaca-Blinder分解及其改进、Brown分解及其改进和JMP1991分解"三足鼎立"的局面,而Oax-aea-Blinder分解则是最基础也是最经典的一种方法.分布分解方法主要由JMP1993分解、DFL分解、MM2005分解、FL1998分解、Lemieux分解、Q-JMP分解和FFL分解"七剑合璧",其中前三种方法尤具奠基性.本文系统地梳理了这些分解方法之间的传承联结,以期形成一幅较为完整的工资差异分解方法演进的向导图.     

The composition of wage differentials between migrants and natives

We consider the role of unobservables, such as differences in search frictions, reservation wages, and productivities for the explanation of wage differentials between migrants and natives. We disentangle these by estimating an empirical general equilibrium search model with on-the-job search due to Bontemps et al. (1999) on segments of the labour market defined by occupation, age, and nationality using a large scale German administrative dataset.The native-migrant wage differential is then decomposed into several parts, and we focus especially on the component that we label “migrant effect”, being the difference in wage offers between natives and migrants in the same occupation-age segment in firms of the same productivity. Counterfactual decompositions of wage differentials allow us to identify and quantify their drivers, thus explaining within a common framework what is often labelled the unexplained wage gap.     

Valuing risk reductions: Incorporating risk heterogeneity into a revealed preference framework

Our study expands the hedonic wage framework to take advantage of the inherent differences in workplace deaths, both in type and probability of occurrence, and examines revealed preferences over these heterogeneous risks. We use data on all fatal workplace deaths in the US from 1992 to 1997 and develop risk rates that are differentiated by how the fatal injury occurred. Within sample tests of the equality of compensating wage differentials for heterogeneous risks indicate that we can reject aggregation of homicide risks with other sources of workplace fatalities. However, our results are not without qualification and highlight important nuances of the labor market as related to estimating compensating wage differentials for risks that have generally been ignored in the previous literature.     

INTERNATIONAL COMPARISONS OF INTER-INDUSTRY WAGE DIFFERENTIALS

We use OECD data to examine inter-industry wage differentials (relative wages among industries) for 14 OECD countries over the period 1970–85. We find, first, that the industrial wage structures have shown remarkable stability over time in terms of rank order for all the countries in the sample. Second, despite their rank order stability, wage structures show a tendency to expand or contract. While the U.S. has shown increasing industry wage dispersion between 1970 and 1985, the pattern is very mixed for other countries. Unionization is a significant factor in explaining cross-country differences. Third, industry wage rankings show some evidence of becoming increasingly similar across nations over time, and this movement is associated with a convergence of per capita incomes. Fourth, industry wage differentials are positively related to an industry's productivity growth, output growth, capital intensity, and export orientation.     

Trade, technology, and unemployment: the role of endogenous skill formation

Abstract .  This paper analyses trade in an asymmetric  2 × 2 × 2  world, where the two countries ('Europe' and 'America') differ in their preferences towards wage inequality. Fair wage considerations compress wage differentials in both countries. European workers are more averse to wage inequality, and Europe is characterized by lower wage differentials and higher unemployment. Allowing for endogenous skill formation, the effects of a globalization shock, global technological change, and a change in the educational capital stock on skill premia and employment levels are derived. In contrast to a model with exogenous factor supplies, international wage and unemployment differentials are affected by global shocks.     

Performance-related pay and gender wage differences

We study the impact of performance-related pay (PRP) on gender wage differences using Finnish-linked employer–employee panel data. Controlling for unobserved person and firm effects, we find that bonuses increase women’s earnings slightly less than men’s, but the economic significance of the difference is negligible. Piece rates and reward rates, however, tend to increase gender wage differentials. Thus, the nature of a PRP plan is important for gauging the impact of PRP on gender wage differentials. A comparison with OLS results shows the importance of controlling for an unobserved person and firm effects.     

Inter industry and occupational wage differentials in Italy

The vast literture on wage determination in the post-war era extensively documents the existence of large and persistent wage differentials among industries and workers of comparable skills. This paper addresses the issue of wage dispersion in the context of the Italian economy. The stability over time of industry relative wages confirme previous results obtained for the other countries. A wide class of earings equations is estimated using microdata for the Italian manufacturing industry. The results provide little evidence in support of the view that wage dispersion can be explained by either unmeasured workers' charcteristics or by compensating wage differentials. Conversely, the estimated pattern of industry-occupation wage differentials is consistent with the existence of rent sharing mechanisms and fairness considerations.     

Generalized measures of wage differentials

This paper considers measures of wage differentials not solely determined by mean comparisons but summarizing differences across complete wage distributions. The approach builds on considerations of risk or inequality aversion and on standard expected utility concepts. In an application to the gender pay gap in Luxembourg the disadvantage of women persists according to the proposed measures: lower mean wages for women are not compensated by differences in higher moments of wage distributions (e.g., by less dispersion) at least for realistic assumptions about women preferences toward risk and inequality. The paper also illustrates an original empirical model for wage distributions in the presence of covariates and under endogenous labour market participation.     

不同期限类型劳动合同的工资决定机制及差异——基于中国家庭住户收入调查数据的经验研究

文章利用2002年住户收入调查(CHIP)数据对我国不同期限类型劳动合同的工资决定机制及工资差异进行了经验研究。结果发现,长期劳动合同与短期劳动合同的工资差异符合补偿性工资差别理论,企业对没有签订劳动合同的员工存在工资歧视。排除特征因素和选择性因素,长期劳动合同工的工资比短期劳动合同工低42.84%,比无劳动合同员工高29.6%。文章研究表明:短期劳动合同没有对生产率表现出显著的负面影响,提升劳动合同签订率是比限制短期劳动合同使用更为合适的劳动政策。     

AN EMPIRICAL INVESTIGATION OF THE RELATIONS AMONG WAGE DIFFERENTIALS, PRODUCTIVITY GROWTH, AND TRADE

This article investigates the relations among productivity growth, wage differentials, and net exports in the United States. The time periods considered are the long run and the short run. Cointegration test results indicate that all the test variables are cointegrated. Therefore, productivity growth, wage differentials, and trade are all related in the long run. A short-run investigation of the relations among productivity growth, wage differentials, and trade is conducted within a vector error correction (VEC) estimation structure. The VEC tests indicate that, contrary to the prevailing view, productivity growth and trade have no impact on wage differentials in the short run. At the same time, it is apparent that wage differentials and trade have a positive and statistically significant impact on productivity growth in the United States in the short run.     

中国城市劳动力市场上的性别工资差异

本文描述了中国城市劳动力市场上男女在行业获得和工资上的差异,并且用计量方法对工资差异进行了分解。分解结果表明,男女工资差异主要由同类行业内工资差异引起,而由于两者行业分布不同而带来的工资差异不大;歧视是造成性别之间的工资差异的主要原因,人力资本所起的作用很小。由此,缩小行业内的工资差异,消除对女性的歧视,是缩小工资性别差异的重要途径。     

A comparative analysis of inter-industry wage differentials: industrialized versus developing countries

This study aims to compare the available evidence on inter-industry wage structure for industrialized and developing countries and to find whether the industry wage differentials are consistent and stable independent of time and space. Moreover, it tries to clarify some of the determinants of industry wage differentials. International evidence supports the wage differential regularity across countries, and the factors underlying inter-industry wage differentials are found to be more or less the same for both industrialized and developing countries.     

The Changing Distribution of Male Wages in the U.K.

This paper uses microeconomic data from the U.K. Family Expenditure Surveys (FES) and the General Household Surveys (GHS) to describe and explain changes in the distribution of male wages. Since the late 1970s wage inequality has risen very fast in the U.K., and this rise is characterized both by increasing education and age differentials. We show that a large part of the changes in the U.K. can be summarized quite simply as increases in eduction differentials and a decline of growth of entry level wages which persist subsequently. This fact we interpret as cohort effects. We also show that, like in the U.S., an important aspect of rising wage inequality is increased within-group wage dispersion. Finally we use the GHS to evaluate the role of alternative education measures.     

WAGE DIFFERENTIALS AND OCCUPATIONAL WAGE PREMIA: FIRM-LEVEL EVIDENCE FOR BRAZIL AND CHILE

This paper examines wage differentials at the firm level in Chile and Brazil, using data for 1985 and 1991, and 1987 respectively. The high level of disaggregation in the data available for Chile enables us also to analyze the degree to which wage differentials between individual employers are similar across occupations.
The results of this study reaffirm those of previous research pointing to non-competitive explanations for wage differentials, specifically providing clear evidence that inter-firm wage premia are highly correlated across occupations.     

Does union membership reduce gender earnings differentials? Evidence from employer–employee matched data in China

This paper examines whether union membership reduces gender earnings differentials in the Chinese labour market using an employer–employee matched data set. We have three main findings. First, union membership helps reduce the gender differentials in hourly wage and monthly allowance, but not in monthly basic wage and yearly bonus. Second, ensuring that female workers receive overtime pay is one way by which union membership helps reduce the gender earnings differentials. Third, controlling for firm fixed effects reduces the effect of union membership on the gender gap in hourly wage and monthly allowance, which means that the unobserved firm characteristics might impact the effect of union membership on gender earnings differentials.
