Temporary Help Work: Earnings,Wages, and Multiple Job Holding*

Temporary help services (THS) employment has been growing in size, particularly among disadvantaged workers. An extended policy debate focuses on the low earnings, limited benefits, and insecurity that such jobs appear to provide. We investigate the earnings and wage differentials observed between THS and other jobs in a sample of disadvantaged workers. We find lower quarterly earnings at THS jobs but a $1 per hour wage premium. We reconcile these findings in terms of the shorter duration and lower hours worked at THS jobs. We interpret the premium as a compensating wage differential.     

Output Pay and Ethnic Wage Differentials: Canadian Evidence

Using the Workplace and Employee Survey, we are the first to examine the association between payment method and ethnic wage differentials in Canada. Following earlier theory, we hypothesize that output pay tying earnings to productivity makes it more difficult for employers to discriminate. The empirical estimations show that non‐Europeans in Canada paid by time rates receive lower earnings than Europeans paid by time rates. Yet, non‐Europeans paid by output pay receive virtually identical earnings to their European counterparts.     

The NBA, Exit Discrimination, and Career Earnings

The purpose of this article is threefold. First, it complements the many wage discrimination studies by examining exit discrimination in the NBA using a decade's worth of data (the 1980s). White players have a 36 percent lower risk of being cut than black players, ceteris paribus , translating into an expected career length of 7.5 seasons for an apparently similar player who is white and 5.5 seasons for the same player who is black. Second, the career earnings effect of exit discrimination in the 1980s is larger ($808,000) than the career earnings effect of wage discrimination ($329,000). Third, our data are consistent with the hypothesis that customer racial discrimination is the reason for the observed exit discrimination.     

What Has Been Happening to Pay in the Public-Service Sector of the British Economy? Developments over the Period 1970–1992

This study presents a detailed analysis of the most important developments in public-service workers' pay over the period since 1970. It records the real earnings growth of all the largest groups of public-service workers in Britain and details the consequences of the different rates of earnings growth enjoyed by the various groups for pay differentials and relative pay in the public sector. It details the size of wage settlements and calculates the magnitude of wage drift for all major groups of public-service-sector workers, and it considers the extent to which the fastest rates of earnings growth appear to result from particular institutional arrangements for determining pay, offering a brief discussion of the role of pay review bodies in this process. The study uses unpublished data from the New Earnings Survey together with detailed information on the size and timing of wage settlements over the period 1970–1992.     

The Impact of Post-School Joblessness on Male Black-White Wage Differentials

This study examines the employment undercurrents of the divergence in black-white wages for young males in the 1980s. By integrating school-to-work transition literature with black-white research on earnings differences, we establish a framework for linking employment during the school-to-work transition and subsequent wage differentials. We empirically confirm this link using the youth cohort of the National Longitudinal Surveys. Results suggest that the higher rates of joblessness among a subset of black youth directly translate into lower earnings for blacks and produce black-white wage divergence. Young black males with extremely high levels of joblessness during the school-to-work period face the greatest reduction in relative wages.     

The Gender Pay Gap for Private‐Sector Employees in Canada and Britain

The gender earnings differentials for private‐sector employees in Britain and Canada are similar, substantial and significant. Using linked employer–employee data, we show that women are more likely to be employed in low‐wage workplaces than men in both counties. After accounting for the workplace, women continue to earn less than comparable men. Although men and women face a more equal pay structure within their workplace than they do across workplaces, a substantial portion of the gender pay gap in both countries remains unexplained by the individual characteristics or workplace effects considered in this study.     

Who Is Affected by the Minimum Wage?

Prior surveys of empirical research on the minimum wage have been organized around the question “What does the minimum wage affect?” This survey is organized around the question “Who is affected by the minimum wage?” We review the consequences of the minimum wage for teens and young workers, men and women, African Americans and Hispanics, the less educated, workers in low‐wage industries, and low‐wage/low‐income populations. Although there is almost universal agreement that the minimum wage boosts earnings, evidence for a negative employment effect varies between mixed and nonexistent. An important gap in the literature is the paucity of research on low‐wage/low‐income groups.     

Five Reasons Why Wages Vary Among Employers

This paper reviews the literature on wage differences among industries and establishments. After surveying the empirical evidence on intra- and interindustry wage differentials, five alternative explanations for employer-based wage differentials among observation equivalent workers are described. The paper concludes with a summary, a discussion of policy implications, and directions for future research.     

Effects of Skill and Attitudes on Employee Performance and Earnings

This study uses original survey and archival data from factory and office employees in one firm to relate differences among individual employees' performance to differences in their skill and attitudes about work, and to test the association between employees' earnings and their performance, skill, and attitudes. We suggest that the way in which skill and attitudes affect performance will depend on the type of work that is done. The main results show that among factory employees, those who have on-the-job training and longer experience receive better performance ratings than those without training and with less experience. Factory employees' earnings depend on their performance, following the human capital model of wage determination. Among office workers, training and experience do not significantly affect performance ratings; instead, higher-rated employees have more positive attitudes about work. Office employees' earnings depend on their classroom training, experience, and attitudes, but not on their rated performance.     

The effect of discrimination and of industry segmentation on Japanese wage differentials in relation to education

The paper investigates Japanese wage differentials based on the concept of industrial division. The labor market is examined for two sectors separately, namely competitive sectors and non-competitive sectors. The effects of female-male difference, of human capital, and of occupation also are examined, and the cost of discrimination is estimated. By applying several quantitative methods, it was found that worker characteristics such as education, length of service and age were treated differently by sector, sex and occupation. Also, wage differentials by sex were mostly rooted in differential treatment of worker characteristics, while wage differentials by sector were explained largely by firm size component. The above general results, however, are greatly modified by workers' occupations and industrial divisions.     

The Effect of Minimum Wages on Labour Market Outcomes: County‐Level Estimates from the Restaurant‐and‐Bar Sector

We use US county‐level data on employment and earnings in the restaurant‐and‐bar sector to evaluate the impact of minimum‐wage changes in low‐wage labour markets. Our estimated models are consistent with a simple competitive model in which supply‐and‐demand factors affect both the equilibrium outcome and the probability of the minimum wage being binding. Our evidence does not suggest that minimum wages reduce employment once controls for trends in county‐level sectoral employment are incorporated. Rather, employment appears to exhibit an independent downward trend in states that have increased their minimum wages relative to states that have not, thereby predisposing estimates towards reporting negative outcomes.     

Unobserved Worker Quality and Inter-Industry Wage Differentials*

This study quantitatively assesses two alternative explanations for inter-industry wage differentials: worker heterogeneity in the form of unobserved quality and firm heterogeneity in the form of a firm's willingness to pay (WTP) for workers' productive attributes. Building on hedonic models of differentiated product demand, we develop an empirical hedonic model of labor demand and apply a two-stage nonparametric procedure to recover worker and firm heterogeneities. In the first stage we recover unmeasured worker quality by estimating market-specific hedonic wage functions nonparametrically. In the second stage we infer each firm's WTP parameters for worker attributes by using first-order conditions from the demand model. We apply our approach to quantify inter-industry wage differentials on the basis of individual data from the NLSY79 and find that worker quality accounts for approximately two thirds of the inter-industry wage differentials.     

Earnings Growth Among Young Less-Educated Business Owners

Using data from the National Longitudinal Survey of Youth (NLSY), I examine the earnings patterns of young less-educated business owners and make comparisons with young less-educated wage/salary workers. Estimates from fixed-effects earnings regressions indicate that the self-employed experience faster earnings growth on average than wage/salary workers after a few initial years of slower growth. I also find some evidence suggesting that a relatively high percentage of less-educated business owners, especially men, experience either rapid earnings growth or large annual losses.     

Compensating Wage Differentials versus Efficiency Wages: An Empirical Study of Job Autonomy and Wages

Efficiency wage theory as incorporated in the shirking model predicts that firms may substitute wage premiums for costly monitoring. This means that wage premiums should be expected for loosely monitored workers. By regarding extensive monitoring as a lack of job autonomy, efficiency wage theory predicts a positive relation between autonomy and wages. The theory of compensating wage differentials, however, predicts a negative relation between autonomy and wages. When workers prefer autonomous jobs, employers have to offer higher wages for less autonomous jobs in order to recruit labor.
Swedish micro data are analyzed in order to examine the predictions of these theories. A proxy for the monitoring problem of the firm measures workers' possibilities of effort variation. Since this proxy is autonomy, it enables us to test the two rival hypotheses on the relation between job autonomy and wages. We find a positive relation in the private sector as predicted by the efficiency wage hypotheses and a negative relation in the case of the public sector, which accords with the theory of compensating wage differentials.     

Tipped Wage Effects on Earnings and Employment in Full‐Service Restaurants

We exploit more than 20 years of changes in state‐level tipped wage policy and estimate earnings and employment effects of the tipped wage using county‐level panel data on full‐service restaurants (FSR). We extend earlier work by Dube, Lester, and Reich ( 2010 ) and compare outcomes between contiguous counties that straddle a state border. We find a 10‐percent increase in the tipped wage increases earnings in FSRs about 0.4 percent. Employment elasticities are sensitive to the inclusion of controls for unobserved spatial heterogeneity. In our preferred models, we find small, insignificant effects of the tipped wage on FSR employment.     

Trade Union Decline and Union Wage Effects in Australia

Union density in Australia fell precipitously in the 1990s. This study investigates how union wage effects may have changed as a result. The findings from 1993 data suggest that union/nonunion wage differentials were very small, especially among workers in high-density industries. By 2001 the overall union wage effect had increased significantly; however, the union/nonunion wage differential was no longer correlated with union density at the industry level.     

Public–Private Sector Wage Gap in Australia: Variation along the Distribution

Previous research on public–private wage differentials in Australia has focused on the mean of the conditional wage distribution. Using six waves of the Household, Income and Labour Dynamics in Australia survey, this study employs quantile regressions to examine whether the sectoral wage effect varies along the wage distribution. For females, public sector wage premiums are relatively stable for almost the entire distribution. For males, they decrease monotonically and are negative for the top half of the distribution. The decomposition results show that the observed differences in individuals and job characteristics explain a substantial proportion of the sectoral wage gap.     

Does an Entrepreneurial Career Pay for Women in China?

Using data from the Chinese Household Income Project survey in 2013, our male–female pay‐gap decomposition illustrates that the gender earnings gap is larger among the self‐employed than the wage‐employed after controlling for the effect of various pay‐determining characteristics. Our self‐employed versus wage‐employed decomposition also controls for selection into self‐employment as well as those pay‐determining characteristics. We find that wage‐employed women would earn less than their current earnings if they shifted to self‐employment, while wage‐employed men would earn more than their current earnings if they became self‐employed. In essence, self‐employed women suffer from double jeopardy. They not only earn less than men in self‐employment due to lower returns for the same pay‐determining characteristics, but women in self‐employment also earn less than women in wage employment when they have the same pay‐determining characteristics.     

A Reexamination of Public-Sector Wage Differentials in the United States: Evidence from the NLSY with Geocode

While many researchers have sought to estimate federal-private wage differentials in the United States, most of them ignore the issues of unobserved heterogeneity and selectivity among sectors. This article seeks to fill the gap in previous literature by using a more appropriate data set and several compelling techniques. The main results suggest substantial bias in ordinary least squares (OLS) estimates of federal-private wage differentials due to individual heterogeneity and self-selection. The direction of bias under selectivity correction (upward for men and downward for women) is consistent with results from both test-score approach estimates and the fixed-effects estimates.     

Does Technological Change Affect Union Wage Bargaining Power?

This paper uses data from a survey of Canadian establishments to consider the effects of computer-based process technological change on wage bargaining power. The analysis finds that union wage differentials for blue-collar workers as a whole were lower among firms that had introduced process computerization than among those that had not. The relationship between technological change and the union wage premium differed, however, for skilled and unskilled labour. The union wage effect was lower for skilled workers and higher for general manual occupations in the sub-sample where process computerization had occurred. Explanations for these observed relationships appear to involve both economic and institutional components.
