Racial Differences in Labor Market Values of a Statistical Life

This article constructs measures of job fatality rates for black and white workers using information on job-related fatalities from 1992–1997. The fatality rates for black employees are somewhat greater than those for whites. Each of these groups receives significant compensating wage differentials for fatality risks, controlling for nonfatal risks and expected workers' compensation benefits. The implicit value of a statistical life is lower for black workers than for whites. These results in conjunction with evidence that blacks receive less annual compensation for fatality risks than do whites imply that black and white workers face different market offer curves that are flatter for blacks than for whites.     

Discounting health and money: New evidence using a more robust method

This study compares discounting for money and health in a field study. We applied the direct method, which measures discounting independent of utility, in a representative French sample, interviewed at home by professional interviewers. We found more discounting for money than for health. The median discount rates (6.5% for money and 2.2% for health) were close to market interest rates, suggesting that at the aggregate level the direct method solves the puzzle of unrealistically high discount rates typically observed in applied economics. Constant discounting fitted the data better than the hyperbolic discounting models that we considered. The substantial individual heterogeneity in discounting was correlated with age and occupation.     

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.     

Avoiding the curves: Direct elicitation of time preferences

We propose and test a new method for eliciting curvature-controlled discount rates that are invariant to the form of the utility function. Our method uses a single elicitation task and obtains individual discount rates without knowledge of risk attitude or parametric assumptions about the form of the utility function. We compare our method to a double elicitation technique in which the utility function and discount rate are jointly estimated. Our experiment shows that these methods yield consistent estimates of the discount rate, which is reassuring given the wide range of estimates in the literature. We find little evidence of probability weighting, but in a second experiment, we observe that discount rates are sensitive to the length of the front-end delay, suggesting present bias. When the front-end delay is at least two weeks, we estimate average discount rates to be 11.3 and 12.2% in the two experiments.     

Discounting statistical lives

Benefit-cost analysis of government projects that reduce health risks over an extended period of time requires an estimate of the value of a future life. This in turn requires a discount rate. We suggest and carry out a method to estimate the discount rate using observations on discrete choices between projects with different time horizons. This method is implemented in a survey context. For our primary example, the estimated median discount rate is close to the market rate. A substantial proportion of the sample is estimated to have quite low discount rates. We provide some evidence that discount rates may differ for different types of risks.This research was supported in part by the U.S. Environmental Protection Agency under Cooperative Agreement in Environmental Economics Research CR-813557-01-0.

Self Selection Bias in the Estimates of Compensating Differentials for Job Risks in India

This study contributes to the hedonic wage literature in developing countries by estimating the collective willingness to pay of a statistical life/injury, using an original data set from the Indian labor market. As self-selection by workers results in biased estimates of the wage premium for job risks, the study uses a modified selectivity bias correction technique. Empirical results indicate substantial heterogeneity in returns to risk. The estimated value of life without selectivity bias is Rs. 56 million (US $3 million), which is substantially larger than the value with selection bias. The estimates provided by the study can aid policy makers, international agencies and other researchers in evaluating health projects in India and other developing countries.     

Individual laboratory-measured discount rates predict field behavior

We estimate discount rates of 555 subjects using a laboratory task and find that these individual discount rates predict inter-individual variation in field behaviors (e.g., exercise, BMI, smoking). The correlation between the discount rate and each field behavior is small: none exceeds 0.28 and many are near 0. However, the discount rate has at least as much predictive power as any variable in our dataset (e.g., sex, age, education). The correlation between the discount rate and field behavior rises when field behaviors are aggregated: these correlations range from 0.09–0.38. We present a model that explains why specific intertemporal choice behaviors are only weakly correlated with discount rates, even though discount rates robustly predict aggregates of intertemporal decisions.     

Risk Compensation or Risk Reduction? Seatbelts,State Laws,and Traffic Fatalities*

Objective. The risk compensation hypothesis suggests that drivers enjoying greater safety will drive more recklessly and thereby impose greater risks on nonoccupants. We provide a test of the risk compensation hypothesis in the context of state seatbelt laws and belt use rates. Methods. Fixed‐effects models with policy and demographic variables are estimated using annual state data from 1985 to 2002 to test the effect of seatbelt laws and seatbelt use rates on logged fatality rates for occupants, pedestrians, motorcyclists, and all nonoccupants in separate models. Results. Contrary to the risk compensation hypothesis, the results indicate that both occupants and nonoccupants enjoy greater safety due to state mandatory use laws and increased safety belt use rates. Conclusion. Overall, seatbelt laws and the higher belt use these laws induce do not increase nonoccupant risk exposure. If anything, these laws and the accompanying increase in belt use result in safer driving behavior.     

Market Transition and Gender Segregation in Urban China*

Objectives. This article analyzes the impact of the new form of economic segmentation, which emerged in urban China during the market transition, on gender segregation and earnings differentials. Methods. I compare both over‐time and across‐city change in gender segregation, and use a series of multi‐level cross‐classified models based on data at three levels: a 1995 national sample of individual workers, industry‐sector data for 1990 and 1995, and city‐level data for 1995. Results. Gender segregation by ownership sector has declined over time now that the state sector has become differentiated and its relative economic advantages wanes. Both earnings differentiation and gender segregation among industries have increased with marketization. In the most marketized cities, the earnings of workers of both sexes in jobs with high rates of female entry are penalized, indicating that marketization exacerbated the negative effect of job feminization on earnings. Conclusions. These findings lend support for the “queuing” perspective that a decline in jobs' relative wages leads to feminization. The making of the Chinese market economy has created a new set of institutional arrangements, which includes that between job feminization and wages.     

The Value of a Statistical Life: A Critical Review of Market Estimates Throughout the World

A substantial literature over the past thirty years has evaluated tradeoffs between money and fatality risks. These values in turn serve as estimates of the value of a statistical life. This article reviews more than 60 studies of mortality risk premiums from ten countries and approximately 40 studies that present estimates of injury risk premiums. This critical review examines a variety of econometric issues, the role of unionization in risk premiums, and the effects of age on the value of a statistical life. Our meta-analysis indicates an income elasticity of the value of a statistical life from about 0.5 to 0.6. The paper also presents a detailed discussion of policy applications of these value of a statistical life estimates and related issues, including risk-risk analysis.     

Individuals' Estimates of the Risks of Death: Part I—A Reassessment of the Previous Evidence

It is widely argued that individuals have biased perceptions of health and safety risks. A reconsideration of the best-known evidence suggests that this view is the erroneous result of a failure to consider the implications of scarce information. Our findings imply that the hypothesis that people make unbiased estimates of hazard rates fails to be rejected by the very data that were initially used to reject it. Thus, we are able to reconcile the alleged existence of widespread bias in risk perception with other findings that such bias is less apparent in the case of job-related hazards. The seeming bias in estimating population-average death rates and the lack of such bias in assessing job risks are two manifestations of the same behavior, which is the optimal acquisition of costly information.     

The heterogeneity of the value of statistical life: Introduction and overview

The refinement in worker fatality risk data used in hedonic wage studies and evidence from new stated preference studies have facilitated the exploration of the heterogeneity of the value of statistical life (VSL). Although the median VSL estimate for workers is $7–$7–8 million, the VSL varies considerably within the worker population. New estimates of the income elasticity of VSL are 1.0 or above, which are consistent with theoretical models linking VSL to the coefficient of relative risk aversion. The specific relationship between VSL and risk aversion is, however, more complex than previously understood. Age differences in VSL are substantial, with young children being accorded especially high VSL amounts. The public’s willingness to pay to reduce risks is reduced if those being protected are perceived as being blameworthy due to their responsibility for contributing to the risk.     

Judgmental Discounting and Environmental Risk Perception: Dimensional Similarities, Domain Differences, and Implications for Sustainability

Environmental risks constitute a special category of risks because they often involve consequences that are highly uncertain, strongly delayed, occurring at distant places, and—therefore—mostly borne by others. Economic, decision–theoretic, and psychological research about the way people deal with such consequences is reviewed. Two major findings are presented: first, there is evidence that discounting mechanisms are stable across different preference dimensions (uncertainty, temporal, spatial, and social distance). Second, discount rates tend to vary across different problem domains (e.g., environmental vs. health vs. financial risks). In particular, it appears that temporal discounting is less pronounced for environmental risks than in other domains. Several factors are identified that affect the nature of the risk evaluation process, and it is argued that environmental risks differ from other risks on such factors. These environmental-risk characteristics may have important implications for policy strategies to promote environmental sustainability. Contrary to other domains, appealing to the public's long-term preferences may be successful. Also in policy making, insights from standard economic decision theory to environmental decision making should be applied with caution.     

Global Economy and Gender Inequalities: The Case of the Urban Chinese Labor Market*

Objectives. This article examines the effects of economic globalization on gender inequalities in urban China. It argues that the significance of economic globalization on gender inequality depends on its impact on job queues in the labor market of a country. Methods. Using both individual‐ and city‐level data, and a series of multilevel linear and logistic models, we analyze the effects of three city‐level variables on the gender gap in income: foreign direct investment (FDI) per capita, growth rate of FDI, and opening up to overseas investment early on. We also examine gender differences in employment in high‐paying foreign‐invested firms, and in lower‐paying export‐oriented manufacturing. Results. We find no variation in gender gap in income among cities of varying levels of FDI, growth rates of FDI, or whether they were among the earliest to open up to international investment. Women are more likely to be employed in export‐oriented manufacturing industries that offer lower wages and are less likely to work in high‐paying foreign firms and joint ventures. Conclusions. These results suggest that economic globalization profoundly influences gender inequalities by changing the nature of job queues, and men and women are sorted and matched into jobs accordingly. Economic globalization contributed to and perpetuated a gendered distribution of male and female workers in the Chinese urban labor market in the late 1990s.     

How Can You Pull Yourself up by Your Bootstraps, if You Don't Have Boots? Work-Appropriate Clothing for Poor Women

Clothing plays a role in impression formation and may affect poor women's ability to obtain a good job. Style of dress affects perceptions of, expectations for, and responses to job applicants. Clothing worn by a job applicant is a sign of status, power, and ability and may determine success on the interview and/or on the job. Most poor women lack the financial resources necessary to enhance their outward appearance as an impression management technique. A number of programs have been designed to help poor women obtain job-appropriate clothing, but these programs are limited in scope. This study reports on a convenience sample of women (N =10) from a state program that provides clothing to women entering the job market. Comprehensive services that take into account the multiple challenges faced by poor women entering the workforce have yet to be developed. Recommendations for corporate and individual action are provided.     

Assessing a minimum pension guarantee for the voluntary IPS in Turkey

The returns from individual account pension plans are subject to fluctuations in capital markets. This increases income uncertainty for the beneficiary and exposes individuals to the risk of fluctuations in the economy in general and the stock market in particular. A minimum pension guarantee is a way to avoid this pitfall by providing a minimum annuity regardless of the actual investment performance of individual accounts. In this article, we present a cost analysis of a minimum benefit guarantee mechanism for the voluntary Individual Pension System in Turkey. We examine the cost estimates and the probability of providing guaranteed payments under various economic and demographic assumptions.     

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.     

A climate stress test on the financial vulnerability of Italian households and firms

This study presents a novel methodological framework for assessing the exposure of the Italian financial system to climate policy risks, using a micro-founded approach. By combining survey and administrative data with energy accounts and energy prices, we estimate the energy demand elasticity of Italian households and firms at the micro-level and we use this information to simulate the effects of four one-off carbon taxes (corresponding to €50, €100, €200 and €800 per ton of CO₂) on their income and profits. To compute if (and how) carbon taxes might affect the share of financially vulnerable agents and the debt at risk, these estimates are employed as an input for the microsimulation models used to monitor financial stability at the Bank of Italy. According to our results, a level of carbon taxation within the range of €50?200 per ton does not have a sizeable effect on the share of financially vulnerable agents. The micro approach allows us to take into account the heterogeneous transmission channels of climate risks and indicates that the financial risks stemming from climate shocks are limited overall and specific to individual households and industries.
