Flexible Hours,Workplace Authority,and Compensating Wage Differentials in the US

The theory of compensating differentials suggests that workers with flexible schedules will earn less than other workers. Some authors have also contended that the concentration of women in jobs with flexible hours explains a significant part of the gender pay gap. This paper uses data from the US subset of the Comparative Project in Class Analysis to test these hypotheses. These data first indicate that, contrary to popular wisdom, women workers do not have more flexible schedules than men. Second, the really striking differential is by race: black workers have much more rigid schedules than white workers. Third, workers with more authority at the workplace typically have more flexibility than subordinate workers. Finally, the data show that any compensating differentials for flexible hours are small and are offset by returns to workplace authority.     

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。     

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.     

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.     

Firm profitability,regional unemployment and human capital in wage determination

This paper presents an analysis of wage formation in the Norwegian private sector using data for individual workers matched with firm level information and regional unemployment. A key issue is to test whether or not firm specific variables affect individual wages after controlling for individual specific factors and working conditions. The results imply positive effects of firm specific profitability and firm size. The elasticity of wages with respect to value added per worker and firm size is 5% and 3.3%, respectively. Empirical evidence of a downward sloping regional wage curve is also reported, while there is no support of the hypothesis of compensating wage differentials. Since data for three levels of aggregation are used, the OLS estimates of the standard errors are downward biased. Therefore, results using a random effects model are also reported, taking the multi-level structure of the data into account.     

On the distribution of job characteristics: an analysis of the DOT data

We analyse the information in the Dictionary of Occupational Titles to characterize the structure of labour demand. Two dimensions, an intellectual factor and a dexterity factor, capture two-thirds of the variance in job requirements; the remaining (co-)variance cannot be easily structured. Simple linear relationships go a long way in describing the matching between job activities and required worker qualities (Intellect for complex relations to Data and to People, Dexterity for complex relations to Things). There is no dichotomy between mathematical and verbal required skills. Poor working conditions are not restricted to workers in low-level jobs; we find strong support for compensating wage differentials. At more intellectual jobs, men receive less wage compensation for working conditions, while in jobs requiring greater dexterity they receive more. Such a relationship is absent for women.     

Do People with Specific Skills Want More Social Insurance? Not in the United States

Skill specificity is thought to increase preferences for social insurance (Iversen and Soskice, 2001, American Political Science Review 95,875), especially where employment protections are low, notably the United States (Gingrich and Ansell, 2012, Comparative Political Studies 45, 1624). The compensating differentials literature, by contrast, suggests that neither skill specificity, nor labor market protections affect preferences when wages adjust for differences in risks and investment costs. We examine these competing predictions using U.S. data on general and specific skills. Absolute and relative skill specificity have a robust positive correlation with income, but are negatively correlated with preferences for social protection. Our results strongly support the compensating differentials approach.     

WORKER INVESTMENTS IN SAFETY,WORKPLACE ACCIDENTS,AND COMPENSATING WAGE DIFFERENTIALS

The theory of compensating wage differentials (CWDs) assumes that firms supply and workers demand workplace safety, predicting a positive relationship between accident risk and wages. This article allows for safety provision by workers, which predicts a countervailing negative relationship between individual risk and wages: Firms pay higher wages for higher safety‐related productivity. Using National Longitudinal Survey of Youth panel data and data on fatal and nonfatal accidents, our precise CWDs imply a value of a statistical injury of $45.4 thousand and a value of a statistical life of $6.3 million. In line with our model, individual risk and wages are negatively correlated.     

Compensating Wage Differentials with Unemployment: Evidence from China

We estimate the economic value of mortality risk in China using the compensating-wage-differential method. We find a positive and statistically significant correlation between wages and occupational fatality risk. The estimated effect is largest for unskilled workers. Unemployment reduces compensation for risk, which suggests that some of the assumptions under which compensating wage differentials can be interpreted as measures of workers’ preferences for risk and income are invalid when unemployment is high. Workers may be unwilling to quit high-risk jobs when alternative employment is difficult to obtain, violating the assumption of perfect mobility, or some workers (e.g., new migrants) may be poorly informed about between-job differences in risk, violating the assumption of perfect information. These factors suggest our estimates of the value per statistical life (VSL) in China, which range from approximately US$30,000 to US$100,000, may be biased downward. Alternative estimates adjust for heterogeneity of risk within industry by assuming that risk is concentrated among low-skill workers. These estimates, which are likely to be biased downward, range from US$7,000 to US$20,000.      

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.     

THE PRICING OF JOB CHARACTERISTICS WHEN MARKETS DO NOT CLEAR: THEORY AND POLICY IMPLICATIONS*

This article examines nonsequential search when jobs vary with respect to nonpecuniary characteristics. In the presence of frictions in the labor market, the equilibrium job distribution need not show evidence of compensating wage differentials. The model also generates several pervasive features of labor markets: unemployment and vacancies, apparent discrimination, and market segmentation. When workers are homogeneous, restrictions on the range of job offers decrease welfare and cannot reduce unemployment. However, when workers have heterogeneous preferences, such restrictions may lower unemployment, and can even lead to a Pareto improvement in welfare. We consider the impact of policies banning discrimination and regulating working conditions.     

Labour market segmentation and union wage gaps

Abstract

There has been a great deal of research regard the effects of unions on union – non-union wage gap. Most of the studies regarding the impact of unions on wages have assumed that apart from the division between union and non-union workers, the labour market is relatively homogeneous. A number of economists, however, have argued that the labour market is segmented, implying that there are distinct labour markets and that some workers employment opportunities are concentrated in “bad jobs” while other workers employment opportunities are concentrated in “good jobs” which are rationed.

This paper will explore whether the relative wage differential between union and non-union workers differs between the independent primary, subordinate primary and secondary labour markets. Labour market segments are defined using “job zones”. “Job zones” are distinct groups defined by the level of specific vocational preparation necessary for a particular occupation, allowing for the comparison of skill levels and training for each occupation. The data on “job zones” comes from the Occupational Information Network database (O?Net). We estimate separate equations for union and non-union workers in each segment using data from the Current Population Survey and calculate union non-union differentials for each labour market segment. The findings of this paper suggest that the greatest differentials are in secondary labour markets followed by differentials in the subordinate primary labour market and that the smallest wage differentials are in the independent primary labour market.     

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。     

中国劳资关系的城乡户籍差异

本文利用最近的企业和农民工调查数据探讨了劳资关系城乡户籍差异问题。城乡工人在劳资关系各方面的巨大差异源于两个方面 :一是人力资本水平差异和就业企业的差异 ;二是农民工受到的户籍歧视。研究结果发现 ,前者解释了两类工人劳资关系差异的 70 %— 80 % ,说明人力资本和企业状况是决定工人待遇的主要因素 ;后者解释了两类工人劳资关系差异的 2 0 %— 3 0 % ,户籍歧视所造成的差距同样是不容忽视的。除劳动合同方面外 ,农民工在工资、养老保险、医疗保险、失业保险以及工会参与等方面均遭到户籍歧视。研究结果暗示仅仅关注工资收入的城乡歧视是不够的 ,同时也为更全面的劳动力市场校正政策提供了经验支持     

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.     

Health insurer market power and employer size: an empirical evaluation of insurer concentration and wages through compensating differentials

This article explores the differentiated effects of health insurer market concentration on net compensation of employees across distinct firm sizes. Consistent with the existing literature evaluating insurer market concentration and the theory of compensating differentials, we find evidence of higher premiums and reduced net compensation for employees in markets with more concentrated insurers. Furthermore, we find evidence that the magnitude of these effects is distinctly smaller for large employers. This implies that mergers of large health insurance companies may have a significant impact on small businesses but that the effect is mitigated for larger employers.     

Tournament incentives and match outcomes in women's professional tennis

Our research examines the effect of prize money differentials in women's professional tennis tournaments on the probability that the favoured player wins the match. This study adds to the existing literature on tournament theory through its focus on Rosen's (1986) elimination-style, match play tournament model. We estimate a standard probit model using a unique data set containing detailed information on prize money, player-specific characteristics, and match play outcomes for all tournaments played during the 2004 tour sponsored by the Women's Tennis Association (WTA). Our results support predictions by Rosen's tournament model. Larger prize money differentials have a positive, statistically significant effect on the favoured player's probability of winning the match. In addition, the number of stages remaining has a significant, negative effect on winning, consistent with tournament theory predictions associated with the number of contestants in a tournament.     

Physical appearance and earnings: further evidence

The literature contains numerous studies on earnings differentials based on age, race, and gender. Comparatively few studies have examined differences in labour market success related to physical appearance. Using three waves of data collected at two organizations, this paper tested for earnings differentials among workers based on their self-reported appearance. Significant earnings premiums for attractiveness were found for women, but not for men.     

Compensation for environmental services and intergovernmental fiscal transfers: The case of India

This paper studies mechanisms to compensate local government for the public provision of environmental services using the theory of optimal fiscal transfers in India. Especially, we analyzed the role of intergovernmental fiscal transfers in achieving the environmental goal. Simply assigning the functions at appropriate levels does not ensure optimal provision of environmental services. Optimality in resource allocation could be achieved by combining the assignment system with an appropriate compensation mechanism. Intergovernmental fiscal transfers would be a suitable mechanism for compensating the local governments and help in internalizing the spillover effects of providing environmental public goods.
