UNEMPLOYMENT RISK AND COMPENSATING DIFFERENTIALS IN NEW JERSEY MANUFACTURING

We present evidence that low-skill workers received larger compensating differentials than more skilled workers when facing unanticipated unemployment in an era without unemployment insurance. Using information from surveys of New Jersey workers conducted during the 1880s, we test the theory of compensating wage differentials. We find that workers who faced a higher probability of predictable unemployment received compensating differentials and that the size of the differential differed across industries and skill levels. With few firm- or industry-specific skills, unskilled workers were less subject to "informational capture" than skilled workers who had more but less easily transferable human capital.

The relationship between employer‐provided training and the retention of older workers: Evidence from Germany

A substantial portion of Germany's workforce will soon retire, making it difficult for businesses to meet their human capital needs; training older workers may help to manage this demographic transition. The authors therefore examine the relationships between employer‐provided training programmes, wages and retirement among older workers. They find that when establishments offer special training programmes targeted at these workers, women – especially low‐paid women – are less likely to retire, possibly because of consequent wage growth. Their results suggest that such targeted training can indeed play an important role in retaining low‐wage older women and advancing their careers.     

OPTIMAL WAGE TAXATION WHEN HUMAN CAPITAL AND EMPLOYMENT ARE ENDOGENOUS

This paper studies how optimal wage tax conclusions from the classic two‐period life cycle model of human capital accumulation are affected by endogenizing the number of taxpaying workers. In the absence of a corrective policy, young individuals underinvest in human capital from a social perspective because tax premiums for transfers to nonworkers are not actuarially adjusted downward for human capital attainment. A combination of wage taxes and wage subsidies can restore proper price signals. Numerical simulations suggest that even modest employment elasticities can be sufficient to substantially impact the magnitudes and even the signs of optimal wage tax rates. (JEL H21, H3, J24)     

Occupations,Human Capital and Skills

Economists have long recognized that occupations can be used as proxies for skills in wage regressions. Yet the potential existence of non-market factors such as discrimination and occupational choice (sorting) on the basis of job attributes that are separate from, but potentially correlated with, wages makes occupations an imperfect control for skills. In this paper, we consider whether inter-occupational wage differentials that are unexplained by measured human capital are indeed due to differences in unmeasured skill. Using the National Compensation Survey, a large, nationally-representative dataset on jobs and ten different components of job requirements, we compare the effects on residual wage variation of including occupation indicators and these skill requirements measures. We find that although these skill requirements vary across 3-digit occupations, occupation indicators decrease wage residuals by far more than can be explained by skill alone. This indicates that “controlling for occupation” does not equate to controlling for only these skill measures, but also for other factors. Additionally, we find that there is considerable within-occupation variation in skill requirements, and that the amount of variation is not constant across skill levels. As a result, including occupation indicators in a wage model introduces heteroskedasticity that must be accounted for. We suggest that caution be applied when using and interpreting occupation indicators as controls in wage regressions.     

Have unions impeded growing wage dispersion among young workers?

Wage inequality is examined for young males over the period 1980–1993. While wage inequality increased substantially for nonunion workers over this period, wage inequality increased only modestly for union workers. In part, this difference results from divergent trends in skill prices—returns to skill rose in the nonunion sector but contracted slightly in the union sector. In particular, returns to education increased sharply in the nonunion sector while remaining stagnant in the union sector. At least for young workers, these findings suggest that unions have been largely successful in resisting market pressures for greater wage inequality. We also uncover evidence suggesting that, as relative returns to education decline in the union sector, highly educated young workers become less likely to choose union employment. We acknowledge the helpful comments of Dek Terrell, Steve Trejo, and Carol Horton Tremblay.     

Occupational downgrading and wages of New Member States immigrants to Ireland

This paper explores the importance of occupational downgrading in explaining the pay gap of New Member States (NMS) immigrants to Ireland by taking advantage of two data sources, the Census and the Survey on Income and Living Conditions (SILC). The study identifies biases in the coverage of NMS immigrants in SILC that dampen their estimated earnings disadvantage. Corrections to population weights are suggested. These adjustments have a significant impact on results, increasing both the size of the wage penalty of NMS immigrants and the extent to which the pay gap can be explained by occupational downgrading. A replication of published results for the UK reveals similar patterns of penalties for NMS workers in both countries. Factors that may explain the concentration of NMS workers in low‐skill/low‐wage occupations are discussed.     

THE LABOR RESERVE AND THE SKILL DEBATE

Competing assertions abound about changes in the skill structure of wage labor. One claims that workplace changes do not necessarily lead to a general deskilling, but enhance skill levels for certain categories of wage labor; another, that such changes contribute to a general deskilling of the paid workforce. Despite having been the focus of much research, these competing assertions remain unresolved. Braverman's discussion of the labor reserve and its pattern of inclusion into the paid workforce promises one possible resolution. Incorporation of a sizable proportion of female workers from the latent labor reserve negated a trend towards an increased proportion of skilled workers in the U.S. paid workforce from 1950 to 1987. Implications of the particular pattern of inclusion and exclusion of this labor reserve are discussed in terms of the debate surrounding the deskilling and reskilling of wage labor in general.     

Occupational Human Capital and Wages: The Role of Skills Transferability Across Occupations

This paper examines the effect of accumulated human capital, and particularly occupational human capital, on the workers’ wages. Unlike previous studies that apply occupational tenure as a proxy for occupational human capital, this paper applies the concept of Shaw’s (1984) occupational human capital to capture the transferability of occupational skills and estimates a new measure of occupational human capital, so-called occupational investment. Using the National Longitudinal Survey of Youth (NLSY) from 1979 to 2000, the key findings of this paper suggest that occupational skills from the previous jobs can also affect the workers’ wages at the current job and that occupational investment is one of the important sources of wages supporting the Shaw’s original work on wage determination. Specifically, 5 years of (3-digit) occupational investment relative to current occupational tenure could lead to a wage increase of 7.7 to 18.4 %. I also find that the general labor market experience accounts for a large share of workers’ wages.     

From classes to copulas: wages,capital, and top incomes

Public debates about the rise in top income shares often focus on the growing dispersion in earnings, and the soaring pay for top executives and financial-sector employees. But can the change in the marginal distribution of earnings on its own explain the rise in top income shares? Are top executives replacing capital owners in the group of top-income earners, or are we rather witnessing a fusion of top capital and top earnings? This paper proposes an extension of the copula framework and uses it for exploring the changing composition of top incomes. It illustrates that changes in top income shares can easily be decomposed into respective changes in the marginal distributions of labour and capital income and the changing association between the two types of income. An application using tax record data from Norway shows that the association between top labour and capital incomes grew stronger between 1995 and 2005 in the top half of the wage and capital income distribution, though it declined for the top 1% of capital income receivers. A gender decomposition demonstrates that the association of wage and capital incomes at the top is particularly striking for men, whilst women are largely under-represented in the top halves of the two marginal distributions.     

DO MINIMUM WAGE INCREASES INFLUENCE WORKER HEALTH?

This study investigates whether minimum wage increases impact worker health in the United States. We consider self‐reported measures of general, mental, and physical health. We use data on lesser‐skilled workers from the 1993 to 2014 Behavioral Risk Factor Surveillance Survey. Among men, we find no evidence that minimum wage increases improve health; instead, we find that such increases lead to worse health outcomes, particularly among unemployed men. We find both worsening general health and improved mental health following minimum wage increases among women. These findings broaden our understanding of the full impacts of minimum wage increases on lesser‐skill workers. (JEL I1, I11, I18)     

ARE WORKERS WILLING TO PAY TO JOIN A BETTER TEAM?

Using data from the Major League Baseball free‐agent market, this study is the first to show that the productivity expected of the team a worker will join produces a significant, negative compensating wage differential. The younger workers in the sample drive this result, trading 25% of their wages to join teams with an expected productivity one standard deviation higher. This investment can be recouped if a reasonable increase in human capital occurs. These results are robust to contract length‐wage simultaneity and indicate that investment in human capital motivates the observed tradeoff, suggesting a new pathway through which human capital accumulation can affect wages. Reliable measures of workers' own past productivity and the productivity expected of a worker's future team provide key advantages to identifying these effects. (JEL J31, J24, M54)     

JOB SIGNALLING and WELFARE IMPROVING MINIMUM WAGE LAWS

Job market signalling (via education) models assume workers know their marginal productivities before accepting jobs, but employers do not. Yet modern theories of the firm predict positive cross partial derivatives among factors. Factor owners thus cannot know their marginal products before interacting with others. Any empirical claim that education is being used for socially wasteful signalling is therefore suspect. Exceptional but underpaid workers can in any case shirk down to the common level instead of obtaining education. The recent finding that minimum wage laws could curb wasteful signalling might thus be a solution in search of a problem.     

Union wages, rents, and skills in health care labor markets

We examine the effect of unions on the earnings of health care workers, with emphasis on the measurement and sources of union wage premiums. Using data constructed from the 1973 though 1994 Current Population Surveys, standard union premium estimates are found to be substantially lower among workers in health care than in other sectors of the economy, and to be smaller among higher skill than among lower skill occupational groups. Longitudinal analysis of workers switching union status, which controls for worker-specific skills, indicates a small impact of unions on earnings within both high and low skilled health care occupations. Evidence is found for small, but significant, union threat effects in health care labor markets. It has been argued that recent legal changes in bargaining unit determination should enhance union organizing and bargaining power. Although we cannot rule this out, such effects are not readily apparent in our data. The authors appreciate the assistance of David Macpherson, who helped develop the CPS data files used in the paper.     

FINANCIAL DEVELOPMENT AND WAGE INEQUALITY: THEORY AND EVIDENCE

We argue that financial market development contributed to the rise in the skill premium and residual wage inequality in the United States since the 1980s. We present an endogenous growth model with imperfect credit markets and establish how improving the efficiency of these markets affects modes of production, innovation, and wage dispersion between skilled and unskilled workers. The experience of U.S. states following banking deregulation provides empirical support for our hypothesis. We find that wages of skilled workers increased by between 0.5% and 6.3% following deregulation while those of unskilled workers fell by between 3.5% and 8.7%. Similarly, residual (or within‐group) inequality increased; the 90–50 percentile ratio of residuals from a Mincerian wage regression and their standard deviation increased by 4.2% and 1.7%, respectively.

The Wages of Aging: Time-Related Determinants of Earnings in the Southern Textile Industry*

The author distinguishes three time-related worker characteristics: physical facility, skill, and firm attachment. In an analysis of wage determination for a sample of textile production workers physical facility and firm attachment, but not skill, had significant curvilinear effects, These, along with exogenous effects of gender and race and endogenous effects of assignments to machine maintenance and to a weave room, are interpreted as reflecting power relations in the contemporary context of the southern textile labor process and labor market. The analysis emphasizes the critical importance of contextual considerations in operationalization, specification, and interpretation for wage determination studies.     

WAGE REDUCTION, UNEMPLOYMENT AND SPECIFIC HUMAN CAPITAL

This paper re-examines the specific human capital hypothesis concerning short-run employment variation to analyze the circumstances in which wage reductions and/or layoffs will occur. By relaxing the usual assumption of downward wage rigidity, we show that the specificity of training influences the attractiveness of wage reduction compared to job separation. The choice of adjustments is analyzed and implications are drawn concerning the impact of the level of specific skill and of other factors on the choice and on the magnitude of such wage reductions as occur. These implications are tested with data on the Seattle recession of 1970-72.     

Minimum Wages in a Segmented Labor Market: Evidence from South Africa

The segmented labor market model describes the impacts of minimum wages on covered and uncovered sectors. This paper examines the impacts of an industry-specific minimum wage in South Africa, a state characterized by high unemployment, a robust union movement, and the presence of a large informal sector. Under the industry-specific wage law, formal agricultural and household workers are covered, while workers in other sectors are not. The unique aspect of this paper lies in the ability to compare the impacts of minimum wage legislation on formal covered, informal covered, formal uncovered, and informal uncovered workers. This natural experiment allows us to test whether industry-specific minimum wage legislation leads to higher wages, whether wage increases are restricted solely to covered formal sectors or if there are spillover effects, and whether such legislation manifests in disemployment effects. We find evidence of higher wages yet disemployment among black workers in formal markets. In informal markets we find no employment effects, but higher wages in formal markets appear to have spilled over into informal markets in covered sectors.     

Noncitizen Employment and the Wages of Healthcare Support Workers in the US

This study examines the relative wages of citizens and noncitizens employed as healthcare support workers as well as examines the effect of noncitizen support worker employment on the wages of citizen support workers. Relative wage findings reveal noncitizen support workers with less than eight years of US residency receive a noncitizen-citizen wage discount statistically significantly greater than the legal maximum of 5% below the local prevailing wage. These low relative wage levels could contribute to lower wages for citizen support workers, however elasticity of substitution findings suggest noncitizen support workers are not close substitutes for healthcare support workers who are US citizens. In addition, wage effect findings do not reveal a negative influence of noncitizen employment on the wages of native born US citizen support workers, while these findings reveal a relatively small wage decline for naturalized support workers. These findings are consistent with the citizen status job heterogeneity hypothesis. Nonetheless, finding noncitizen-citizen wage differences does not allow for ruling out the possibility of weak enforcement of prevailing wage legislation and possible employment of undocumented workers.     

Education,Skills, and Wage Gaps in Canada and the United States

We analyse data from the Programme for the International Assessment of Adult Competencies to reveal that immigrants in Canada and the United States make over $200 less per month than native‐born workers. In the United States, immigrants disproportionately work in low‐wage occupations, leading to large mean national differences between immigrants and native workers. The wage differential disappears after accounting for education and cognitive skills, indicating policies must focus on reducing education and skill gaps in the United States. In Canada, an immigrant wage gap persists in nearly all occupational fields, suggesting that the better skilled and educated immigrants in Canada are not receiving the same wage premium as native workers. We close with implications for policy and future research.
