Unions,employment risks,and market provision of employment risk differentials

The role of unions in providing compensating differentials for wage and hours risk is analyzed. Unions are shown to increase wages for workers in more risky jobs. A negative compensating differential for nonunion workers is taken as evidence of worker-specific, or supply-side risk. This component of risk is removed by controlling for union status, based on the belief that unionized firms will be more likely to filter out high-risk unproductive workers. Hours risk is compensated for in the labor market, while wage risk is not.     

Dirty money: Is there a wage premium for working in a pollution intensive industry?

Within a compensating wage differential framework we investigate whether there is a wage premium for working in a pollution intensive industry. Our results for the economy as a whole suggest a small wage premium of approximately one quarter of one percent associated with the risk of working in a dirty job. This premium rises to over fifteen percent for those individuals who work in one of the five dirtiest industries. We also find evidence of a fatal risk wage premium, providing estimates of the value of a statistical life of between ￡12 million and ￡19 million (2000 prices).     

Wage compensation for job-related illness: Evidence from a matched employer and employee survey in the UK

Despite voluminous studies on compensating wage differentials for job-related fatal or non-fatal injuries, there remain few published studies confirming the existence of compensating wage differentials for job-related illness. This study utilizes a recently completed UK employer-employee survey to look at this specific issue. I find there is strong evidence of wage compensation for job-related illness risk for both male and female employees in the UK. The estimated wage compensation for one job-related illness episode per year ranges from 27% to 140% of annual earnings depending on gender and estimation approaches.     

Compensating Wage Differentials for Fatal and Nonfatal Injury Risk by Gender and Race

Our research examines risk compensation by gender and race using occupation, gender, and race specific fatal and nonfatal injury rates and a data set sufficiently large to produce accurate estimates across fairly narrow groups. The data provide strong evidence that men earn compensating differentials for both fatal and nonfatal injury risk and women earn compensating differentials for nonfatal injury risk. Female wage premiums for nonfatal injury risk exceed male wage premiums by a factor of more than three. Nonfatal injury risk compensation is widespread among the various demographic groups although largest for white women. Fatal injury risk compensation is more isolated with only white and Hispanic males earning significantly higher pay for greater amounts of fatal injury risk.     

Do Wages Compensate for Risk of Unemployment? Parametric and Semiparametric Evidence from Seasonal Jobs

Due to unique institutional and technological factors, seasonal agricultural jobs are characterized by much higher risk of unemployment than similar permanent jobs. I estimate compensating differentials for risk of unemployment and compare those with unemployment insurance benefits provided by the government. I use two sets of estimators. First, I calculate parametric estimates with Heckman correction. Second, I compute three versions of a distribution-free semiparametric estimator which is robust to misspecification of the residual distribution. The main finding of the paper is that there exists a positive compensating differential of 15.5% of the average wage. This corresponds to an implicit replacement rate significantly larger than the typical unemployment benefit.     

Cigarette smoking,illicit drug use and the value of life

This article investigates the relationship between cigarette smoking and illicit drug use and compensating wage differentials for the risk of job-related death. Knowledge of an individual's experiences with cigarettes and illicit drugs is used to identify worker heterogeneity in job-risk preferences. The results show that individuals who are both nonsmokers and nondrug users work in the safest jobs and receive the highest compensating wage differentials for job-related risk. Significant differences in job risk and compensating differentials are also found between smokers and nonsmokers and drug users and nondrug users. Estimates of the statistical value of life increase from $2.9 million to $7.1 million when moving from the full sample of workers to those individuals classified as nonsmokers and non-drug users.     

Import competition, employment and wages in U.S. manufacturing

This paper uses cointegration analysis to examine if employment and wages in the U.S. manufacturing sector exhibit any long run relationship with import competition. While overall the cointegration analysis supports the results reported in Revenga’s (1992) panel study it indicates that in the long run a positive correlation between import price and employment and/or a negative correlation between import price and wage are sector sensitive. There is also a considerable variation in the magnitude of employment and wage elasticities.     

Cross‐Border Earnings of U.S. Natives Along the U.S.‐Mexico Border*

Objective. This study explores whether the earnings of U.S.‐born cross‐border workers differ from those of their U.S.‐employed counterparts. We also analyze whether the cross‐border/non‐cross‐border wage differential changed during the 1990s—a decade when U.S.‐Mexico trade intensified and the maquiladora industry expanded. Methods. Employing decennial U.S. Census data from 1990 and 2000, this article estimates earnings functions and uses wage decomposition analysis to study changes in the earnings of U.S.‐born Hispanic and non‐Hispanic cross‐border workers. Results. The number of U.S.‐native cross‐border workers, while relatively small, increased significantly between 1990 and 2000, as did their earnings. A closer examination reveals that this cross‐border earnings premium only developed among non‐Hispanics. Conclusions. These findings indicate that some U.S. natives find lucrative employment opportunities on the Mexican side of the border, which might be diminished by additional restrictions for U.S.‐born residents to easily cross back and forth into Mexico.     

The value of job safety for railroad workers

The value of reducing job risk is estimated using a hedonic wage model and a risk variable that is matched by occupation and state of residence. This study is the first to use the hedonic wage approach to estimate the value of safety in a single industry. Industry-specific estimates will help researchers and labor policymakers better understand the distribution of compensating wage differentials across industries. Our estimated value of job safety for railroad workers is between $21,000 and $26,000 (1980 dollars) per statistical disabling injury, which is somewhat larger than the average of values estimated in previous studies that use cross-industry or crossoccupation aggregate risk data.     

Valuing the risk of workplace sexual harassment

Using data on sexual harassment charges filed with the Equal Employment Opportunity Commission, I calculate the risk of sexual harassment by gender, industry, and age and establish that white females, but not nonwhite females, receive a compensating wage differential for exposure to a higher risk of sexual harassment. I use this risk premium to calculate the value of statistical harassment (VSH) in a manner analogous to the calculation of the value of statistical life (VSL). The VSH is around $7.6 million, about three-quarters of the size of the most-commonly cited levels of the VSL, and far above the maximum damages award for sexual harassment available under federal law. Boosting the maximum damages award to equal the VSH would create the appropriate economic incentives for organizations to deter sexual harassment.     

Competition and Wage Discrimination: The Effects of Interindustry Concentration and Import Penetration*

Objective. Economic theory suggests that competition reduces employers' latitude to engage in wage discrimination ( Becker, 1957 ). This study investigates the impact of foreign and domestic competition on wage discrimination. Method. Utilizing the sample of males in U.S. manufacturing industries from the 1990 Public Use Micro Sample (PUMS), industry wage equations are estimated. In a second stage, the impact of domestic and foreign competition on racial wage disparity is assessed. Results. We find little evidence to support our hypothesis. Conclusions. Notwithstanding, the failure of conventional economic theory to satisfactorily explain racial wage disparity reiterates the need to incorporate alternative theories of discrimination into mainstream economic theory.     

Are there rewards for language skills? Evidence from the earnings of registered nurses

The existing empirical evidence on whether U.S. labor markets reward workers for second-language skills is meager and conflicting. Employing data from the National Sample Survey of Registered Nurses in 2000 and 2004, this study reexamines the positive bilingual–earnings relationship found in the most current research on this topic. We test the relationship using alternative models that explain the wages earned by nurses. The advantage of this approach is that it permits an assessment of how sensitive the results are to changes in the variables used in the model. We find the evidence of a positive bilingual effect on earnings to be mixed. The relationship is sufficiently frail that statistically significant results eventually dissolve as more precise occupational characteristics are included in the wage equation. Moreover, using more current data, we find no evidence of a wage premium paid to nurses for second-language skills. We offer possible explanations for this lack of evidence within this specific occupation.     

Labor Market Outcomes for Legal Mexican Immigrants Under the New Regime of Immigration Enforcement

OBJECTIVES: This paper documents the effects of increasingly restrictive immigration and border policies on Mexican migrant workers in the United States. METHODS: Drawing on data from the Mexican Migration Project we create a data file that links age, education, English language ability, and cumulative U.S. experience in three legal categories (documented, undocumented, guest worker) to the occupational status and wage attained by migrant household heads on their most recent U.S. trip. RESULTS: We find that the wage and occupational returns to various forms of human capital generally declined after harsher policies were imposed and enforcement dramatically increased after 1996, especially for U.S. experience and English language ability. CONCLUSION: These results indicate that the labor market status of legal immigrants has deteriorated significantly in recent years as larger shares of the migrant workforce came to lack labor rights, either because they were undocumented or because they held temporary visas that did not allow mobility or bargaining over wages and working conditions.     

Did We Overestimate the Value of Health?

Adam Smith's idea that wage differences reveal preferences for risk rests on strong theoretical foundations. This paper argues, however, that the dominant approach to identify compensating wage differentials—regressing individual wages on aggregate measures of risk—may lead to arbitrary estimates of these risk differentials. In a dataset with information on both, the incidence of illnesses or injuries across firms and industries, I calculate an implicit value of one injury or illness of about (1990) USD 18,800 pursuing the dominant approach. In contrast, regressing wages on the incidence of risk across firms produces a value of one injury or illness of about USD 11,300.     

The Cost of Parenthood: Unraveling the Effects of Sexual Orientation and Gender on Income*

Objectives. Prior research has repeatedly shown that parenthood affects employment outcomes; mothers have, on average, lower wages and are less likely to be hired than childless women. Some research indicates that this effect of parenthood on employment outcomes is dependent on sexual orientation. In particular, lesbian mothers might be treated more like childless women by those making employment decisions. This article examines the degree to which the lesbian wage advantage can be explained by lesbians avoiding the motherhood wage penalty experienced by heterosexual women. Methods. Drawing on 2000 U.S. Census data, this issue is first explored via ordinary least squares regression equations that estimate the effect of having a child present in the household on income. The Blinder‐Oaxaca method is then employed to decompose the earnings differential between heterosexual and gay individuals. Results. Results indicate that lesbians appear to experience a motherhood advantage that increases their wages by approximately 20 percent. Further, results support the notion that lesbians receive different returns to the presence of children in the household than do heterosexual women. Approximately 35 percent of the wage differential between lesbians and heterosexual women is attributable to differences in returns to child rearing. Conclusion. These findings have relevance for state and federal anti‐discrimination laws and work/family policies, as they provide further insight into the role that gender, and gender‐based assumptions, play in determining employment outcomes.     

The impact of opening markets on Mexican male/female wage and occupational differentials

This article addresses the effect of a more open market under NAFTA on the economic status of Mexican women. It is assumed that increases in export processing and tourism, industries that have a high demand for female labor, will result from the agreement. The approach of this study is to use regression and correlation analysis to compare wage and occupational differences in two Mexican cities: Tijuana, on the U.S.-Mexican border, and Torreon, in the interior. A major findings is that the overall wage gap is statistically significantly lower where there is increased export processing activity, but there appears to be very little change in occupational segregation. Three additional impacts are: first, that labor force participation rates increase for both men and women, but proportionally more for women. Second, the higher labor demand appears to weaken the relationship between the job qualifications of education and experience and wages. Third, wages by gender are more equal, but for the labor force as a whole there is a greater level of wage dispersion.     

Compensating wage differentials for workplace accidents: Evidence for union and nonunion workers in the UK

This article measures compensating wage differentials for job risks for union and nonunion workers. Job risk is made endogenous to avoid a selectivity bias arising if more able people choose safer jobs. We find that this adjustment has a considerable effect on the union group, raising their fatal risk premium above that of non union workers. This implies that there is more variation in unmeasured ability in the unionized group, and that job risk is an inferior good. The fact that unionized workers are also found in safer jobs might therefore be attributable to their greater wealth, rather than to greater“knowledge” in the unionized plant. The estimated statistical value of a life is £8.8 million in 1990 prices for union workers, with nonunion workers about 20% lower.     

Liability risk in the pharmaceutical industry: Tort law in the US and UK

This paper examines the extent to which product liability risk contributes to the high costs of pharmaceuticals in the United States relative to prices in the United Kingdom. Research on pharmaceutical prices rarely accounts for the impact of liability risk, and none that we are aware of compares the United States and United Kingdom. Drawing on a dataset of 77 brand name drugs sold in both the U.S. and the U.K., we analyze relative manufacturers’ factory prices in each nation. We utilize several proxies for liability risk including drug litigation history, the percentage of plaintiff wins, and controlled substance classification. Importantly, under U.S. law there are no caps on the amount that can be awarded to a plaintiff claiming economic losses in the U.S. However, payouts in the U.K. are limited. Accounting for market differences and regulatory environments, we find liability risk can account for a portion of the price differential that exists between the U.S. and U.K., warranting further investigation.     

Importation,SES-selective acculturation,and the weaker SES-health gradients of Mexican immigrants in the United States

Previous studies find U.S. immigrants have weaker socioeconomic gradients in health relative to non-Hispanic Whites and their U.S.-born co-ethnics. Several explanations have been advanced but few have been tested empirically. We use data from the Mexican Family Life Survey and the U.S. National Health Interview Survey, including longitudinal data in the former measuring socioeconomic status (SES) and health previous to emigration, to test if (1) immigrants “import” their gradients from the sending country, or if (2) they may be changing as a result of SES-graded acculturation among Mexican migrant men in two health indicators: obesity and current smoking. We find evidence consistent with the first hypothesis: the gradients of migrants measured prior to coming to the U.S. are not statistically different from those of nonmigrants, as the gradients of each are relatively weak. Although the gradients for obesity and smoking appear to weaken with time spent in the U.S., the differences are not significant, suggesting little support for the selective acculturation hypothesis.     

Willingness to accept equals willingness to pay for labor market estimates of the value of a statistical life

Our research clarifies the conceptual linkages among willingness to pay for additional safety, willingness to accept less safety, and the value of a statistical life (VSL). We present econometric estimates using panel data to analyze the VSL levels associated with job changes that may affect the worker’s exposure to fatal injury risks. Our baseline VSL estimates are $7.7 million and $8.3 million (Y$2001). There is no statistically significant divergence between willingness-to-accept VSL estimates associated with wage increases for greater risks and willingness-to-pay VSL estimates as reflected in wage changes for decreases in risk. Our focal result contrasts with the literature documenting a considerable asymmetry in tradeoff rates for increases and decreases in risk. An important implication for policy is that it is reasonable to use labor market estimates of VSL as a measure of the willingness to pay for additional safety.
