Exploring the Link Between Wages and Psychological Capital

Traditional Mincer-type hedonic wage equations typically fail to account for the effect of psychological capital, in part because such factors are often regarded as unobservable. This article incorporates a measure of psychological capital (specifically, self-esteem) that has been validated in the psychology literature into an otherwise typical hedonic wage model. Then, the sample is divided into race and gender subgroups and estimates are compared. The results suggest that self-esteem does play a role in determining wages for Whites (White men, in particular), but it has no detectable effect on the wages of African-Americans. Data are drawn from the 1979 National Longitudinal Study of Youth. JEL: D (‘Microeconomics’), J (‘Labor and demographic economics’), J31 (‘Wage levels and structure, wage differentials’)

Randomized Safety Inspections and Risk Exposure on the Job: Quasi-experimental Estimates of the Value of a Statistical Life

The value of a statistical life (VSL) is a critical driver of estimated benefits for federal policies designed to improve human health, safety, and environmental exposures. The vast majority of empirical evidence on the magnitude of the VSL arises from hedonic wage models that have been plagued by measurement error and omitted variables. To address these limitations, this paper employs randomly assigned workplace safety inspections to instrument for plant-level risks in a quasi-experimental design. We provide credible causal evidence for the existence of compensating wages for fatality risks and estimate a VSL between $(2016)8 million and $(2016)10 million. (JEL J17, J28, J31, K32)

Effect of Income Heterogeneity on Valuation of Mortality Risk in Taiwan: An Application of Unconditional Quantile Regression Method

According to theory and existing empirical results, heterogeneity in personal characteristics, with income variation being one of them, affects the marginal willingness to pay (WTP) for reducing fatal risk. In this study, the effect of income heterogeneity on the value of statistical life (VSL) in Taiwan through unconditional quantile regression analysis using the data collected by the “Manpower Utilization Survey” is investigated. The results of this empirical study show that the hedonic wage function that was constructed using empirical data from Taiwan was in line with the general form of non-linear function rather than the semi-log function that has been often used in previous studies, which should have great impact on the estimation of the VSL. The empirical results also show that the estimated VSL of Taiwanese labor varied with the difference in wages, which needs to be taken into account when discussing the public policies using VSL.

Meta-analysis of Value of Statistical Life Estimates

Value of Statistical Life (VSL) is one of the most debatable areas in economics. However, VSL is frequently used as a policy instrument for evaluating various safety, health and environmental regulations. Policymakers have to undertake the difficult task of assigning monetary value to the reduction of various health and mortality risks while analyzing safety policies. Compensating wage differential (CWD) for job risks acts as a reference point for valuing mortality risks while VSL serves as a basis to analyze these benefits of risk reduction policies. However, it has been observed in the recent past that VSL estimates vary substantially across various studies. Therefore, it has become necessary for researchers and policymakers to understand the source of this variation in order to aid policymaking. This paper attempts to bring together some of the emerging issues in VSL literature and presents a meta-analysis that is based on 34 observations from 30 hedonic wage-based VSL studies. The results of this meta-analysis show that certain emerging areas in VSL literature such as worker’s compensation benefits, age and long-term health-related job risk require more emphasis and further examination.

New risk rates, inter-industry differentials and the magnitude of VSL estimates

The Census of Fatal Occupational Injury (CFOI) provides data for creating objective measures of workplace risk used in estimations of wage-risk premia for value of statistical life (VSL) calculations. This relatively new data set enables a more theoretically defensible measure for use in hedonic wage equations. However, constructing these rates from the CFOI data necessarily involves creating an industry-occupation matrix defining the “jobs,” deciding whether or not to include the self-employed, and selecting a denominator. These choices in the construction of the risk measure alone, as shown here, result in variations of VSL estimates ranging from $8 million to $18 million. Further, risk measures based on the CFOI data, regardless of construction, are sensitive to simple changes in the specification for the hedonic wage equation. In particular, fixed effects describing the industry in which a worker is employed, as well as the worker’s occupation, are primary influences on the magnitude of the VSL estimates.

The value of air quality and crime in Chile: a hedonic wage approach

ABSTRACTWe estimate the implicit prices of the crime rate and airborne pollution in Chile, using spatially compensating price differentials in the housing and labor markets. We evaluate empirically the impact of different estimation strategies for the wage and rent equations, on the economic value of these two amenities. The results show that increments in the crime rate or in air pollution have a negative impact on welfare and that the estimated welfare measures and their variances are sensitive to selection bias, endogenous amenities and clustering effects. In contrast, the welfare measures do not seem to be very sensitive to the simultaneity bias.
