Aggregation Biases in Estimates of the Value per Statistical Life: Evidence from Longitudinal Matched Worker-Firm Data in Taiwan

This study uses a unique longitudinally-linked employer–employee dataset to estimate the magnitude of bias in estimating the value per statistical life (VSL) that arises from the conventional use of industry-average occupational risk. This unique dataset, covering workers in Taiwan over the period 1998–2002, allows us to distinguish among potential sources of bias including omitted variables and to control for the potential endogeneity of firm-specific job risk with respect to unobserved worker and firm characteristics. We find that VSL estimates based on risk data aggregated by three-digit manufacturing SIC codes are biased downward by an order of magnitude compared with estimates using firm-specific risk that control for endogeneity.     

Analyzing occupational licensing among the states

The study provides new evidence of the influence of occupational regulations on the U.S. economy. Our analysis, unlike previous studies, was able to obtain a representative sample of the population at the state level, which allowed us to estimate the cross-sectional effects of occupational licensing for each state. The state-level analysis demonstrates considerable variation in percentage of the workforce that has attained a license, and unlike minimum wages or unionization, licensing shows no regional patterns in the distribution of occupational licensing. The analysis also shows considerable variation in the influence of licensing on earnings across the states. The national estimates suggest that occupational licensing raises wages by about 11% after controlling for human capital and other observable characteristics. Finally, our analysis shows the influence of occupational regulation on wage inequality across the income distribution.     

Heterogeneous returns to personality: the role of occupational choice

We analyze the role of personality in occupational choice and wages using data from Germany for the years 1992 to 2009. Characterizing personality by use of seven complementary measures (Big Five personality traits, locus of control, and a measure of reciprocity), the empirical findings show that personal characteristics are important determinants of occupational choice. Associated with that, identical personality traits are differently rewarded across occupations. Hence, breaking down the analysis on the level of occupational groups provides more detailed results of returns to personality. By evaluating different personality profiles, we additionally estimate the influence of personality as a whole. The estimates establish occupation-specific patterns of significant returns to particular personality profiles. These findings underline the importance to consider the occupational distribution when analyzing returns to personality due to its heterogeneous valuation.     

VALUE OF LIFE AND INJURY: EVIDENCE FROM A U.S. FISHERY

Here, revealed trade‐offs between monetary rewards and safety risk for shrimp fishermen in the Gulf of Mexico are investigated. Shrimp harvesting is one of the most dangerous occupations in the United States with an occupational fatality rate significantly above the average. The instrumental variables method is employed for estimation of the injuries and fatalities. My estimates of the value of a statistical life and the value of statistical injury, using the sample selection model, are in line with the estimates from other industries and provide useful information for public policy.

OCCUPATIONAL PENSIONS, WAGES, AND JOB MOBILITY IN GERMANY

Pension‐covered workers in Germany are three times less likely to change jobs than workers not covered by an occupational pension scheme. This paper examines the effects of occupational pension coverage and pension portability loss on voluntary job changes using a sample selection model with endogenous switching. The model estimates, derived from western German panel data for 1985–1998, indicate that occupational pension coverage reduces worker mobility by imposing a capital loss on those leaving their job before retirement age. Moreover, pension‐covered workers receive a higher compensation, which discourages mobility. Making pensions portable increases mobility, but from a low initial level.     

Occupational mobility in Australia: A quantitative approach

The major aim of this paper is to formulate and estimate a model to explain occupational mobility in Australia. The main hypotheses advanced in the development of the theoretical model are that occupational mobility varies with excess demand (or supply) in the aggregate labour market, that segmentation occurs within individual markets for specific occupations, and that net mobility between occupations is responsive to changes in relative occupational wage rates after adjustment for differential risks of unemployment. The empirical results support the hypothesis that net mobility is a function of changes in relative occupational certainty equivalent wage rates. Further, the statistical properties of the estimates suggest that the structural approach can be highly successful in comparison to previous reduced-form studies in this area.     

Determinants of occupational change and mobility in rural India

With a view to redress the dearth of economic analysis on occupational dynamics in rural household economies, this study examines the nature and characteristics of occupational change and mobility in rural India. Using the unique WIDER data-set from six villages in West Bengal, India the factors causing a change of primary occupation among those who tried to change occupation over a twelve-month recall period has been analysed. Bivariate probit estimates jointly determining the probability of trying to change occupation and having been successful suggest that success in changing occupation depends crucially on socially constructed ‘status’- being older, male, from larger farming families or having higher schooling experience. They also exemplify the effects of regional diversity, levels of prosperity and different patterns of employment between agricultural and non-agricultural activities.     

Occupational Attainment and Immigrant Economic Progress in Australia*

Using data from the 2001 Australian Census of Population and Housing, on adult men in full‐time employment, this paper augments a conventional human capital earnings function with information on occupations. It also estimates models of occupational attainment. The results from both the earnings function and model of occupational attainment indicate that the limited international transferability of human capital skills results in immigrants entering into relatively low status occupations when they first enter the Australian labour market. Comparison with similar research for the USA suggests that the different immigrant selection regimes (primarily family reunion in the USA, skill‐based immigration in Australia) do not impact on the negative association between current occupational status and pre‐immigration labour market experience.     

Occupational choices of working children in Bangladesh

The article looks into the determinants of occupational choices of working children in Bangladesh. Using data from 6668 Bangladeshi working children aged 5 through 14, the article estimates several binary and multinomial logit regressions, separately for boys and girls. The article confirms that most children work in the informal sector where formal sector’s jurisdiction and regulations are absent. Specifically, the article finds that children are least likely to work in the service occupation and are more likely to work in the textile sector. The findings highlight the diversity in the occupational distribution of child workers by gender and show how their individual and family characteristics influence occupational choices. The service sector, which comprises of mostly maids, is a hidden sector. This sector makes children vulnerable to abuse. Thus, it is suggested that policy makers need to come up with effective legislations that would protect the children who work in the ‘hidden informal’ sector.     

Monetary policy and unemployment: A disaggregated analysis

This paper disaggregates unemployment into broadly defined sectors and occupations. It estimates the impact that a change in the Federal Funds rate (FFR) has on the magnitude and time path of unemployment in each of these sectors and occupations. It finds that there is a substantial differential impact. Specifically, the paper shows that an increase in the nominal Federal Funds rate affects unemployment much more severely in two sectors and in two broad occupational groupings than it does in the others.     

Returns to education in China: a meta-analysis

Within labour economics, returns to education is an area of focused research. Moreover, amongst studies looking at emerging economies, China is the most widely studied economy. While there is a general consensus that returns to education are positive, studies use various datasets and methodologies and consequently present varying estimates of returns to education. We perform a meta-analysis of these estimates of the returns to education in China, addressing issues of heterogeneity in the existing literature and examining whether variations in reported estimates can be explained by study characteristics such as dataset and estimation methods, among others. The meta-regression results show that variations in reported estimates can be accounted for by study characteristics such as data source, estimation method and sample period, among others. The results support the college premium hypothesis and reveal that the returns to education for college graduates are higher than those for other (lower) levels of education.

From engineer to taxi driver? Language proficiency and the occupational skills of immigrants

We examine the ability of immigrants to transfer the occupational human capital they acquired prior to immigration. We first augment a model of occupational choice to study the implications of language proficiency on the cross‐border transferability of occupational human capital. We then explore the empirical predictions using information about the skill requirements from O^*NET and a unique dataset that includes both the last source country occupation and the first four years of occupations in Canada. We supplement the analysis using Census estimates for the same cohort with source country occupational skill requirements predicted using detailed human capital related information such as field of study. We find that male immigrants to Canada were employed in source country occupations that typically require high levels of cognitive skills, but rely less intently on manual skills. Following immigration, they find initial employment in occupations that require the opposite. Consistent with the hypothesized asymmetric role of language in the transferability of previously acquired cognitive and manual skills, these discrepancies are larger among immigrants with limited language fluency.     

Job Changes,Occupational Mobility and Human Capital Acquisition: an Empirical Analysis

Most individuals have more than one job or occupation in their working lives. Most employees are repeatedly faced with the choice of whether to remain in their present job (with the possibility of promotion), or quit to another job in the same occupation with a different firm, or – more radically – change occupation. At each stage in an individual's career, the scope for future job or occupational mobility is largely conditioned by the type and quantity of their human capital. This paper presents an empirical study of the factors which link occupational mobility and the acquisition of either firm-based, occupation-specific or general human capital. The data employed are from a cohort of 1980 UK graduates drawn from the Department of Employment Survey 1987. The econometric work presents estimates of the role of firm-based training and occupation-specific training in the career mobility of qualified manpower in the first seven years in the labour market.     

Demand for redistribution,support for the welfare state,and party identification in Austria

This paper describes subjective wage inequality and the demand for redistribution in Austria using individuals’ estimates of occupational wages from the International Social Survey Program. Although these estimates differ widely across individuals, the data clearly show that most individuals would like to decrease wage inequality, relative to the level of inequality which they perceive to exist. The empirical analysis also shows that the demand for redistribution is strongly associated not only with variables describing self-interested motives for redistribution, but also with perceptions of and social norms with respect to inequality. Further, the demand for redistribution is a strong predictor for whether an individual is supportive of redistribution by the state. On the other hand, however, I find almost no evidence for an empirical association between the demand for redistribution and individuals’ party identification.     

Compensating Wage Differentials with Unemployment: Evidence from China

We estimate the economic value of mortality risk in China using the compensating-wage-differential method. We find a positive and statistically significant correlation between wages and occupational fatality risk. The estimated effect is largest for unskilled workers. Unemployment reduces compensation for risk, which suggests that some of the assumptions under which compensating wage differentials can be interpreted as measures of workers’ preferences for risk and income are invalid when unemployment is high. Workers may be unwilling to quit high-risk jobs when alternative employment is difficult to obtain, violating the assumption of perfect mobility, or some workers (e.g., new migrants) may be poorly informed about between-job differences in risk, violating the assumption of perfect information. These factors suggest our estimates of the value per statistical life (VSL) in China, which range from approximately US$30,000 to US$100,000, may be biased downward. Alternative estimates adjust for heterogeneity of risk within industry by assuming that risk is concentrated among low-skill workers. These estimates, which are likely to be biased downward, range from US$7,000 to US$20,000.      

Estimating Quality‐adjusted Price Changes: Method and Application to VCRs

This paper uses scanner data to generate estimates of quality‐adjusted price changes for video‐recorders. We use hedonic regressions to derive estimates of the changing worth of each quality component. These are then applied to weighted changes in the mix of quality attributes of products to derive estimates of quality‐adjusted price (QAP) changes. The data source used is electronic‐point‐of‐sale (EPOS) scanner data that are available for a wide range of goods. This study provides an example of how such methods can be more widely applied. The estimates of QAP changes correspond to constant‐utility, (hedonic) cost‐of‐living indexes defined in economic theory as the ratio of expenditure functions at constant utility allowing for changing prices and characteristics of goods. This method is proposed as an improvement on the existing direct method , which takes its estimates directly from the coefficients associated with 'time dummies' in a hedonic regression. We finally undertake a matching process, akin to that used by statistical offices, and compare the results. Direct comparisons with RPI estimates and these hedonic approaches are not easy since the approaches use quite different data sets. Our replication of a procedure akin to that used for the RPI on the scanner data set provides insights into sources of potential bias.     

Complementarity and the Measurement of Individual Risk Tradeoffs: Accounting for Quantity and Quality of Life Effects

This paper considers the factors responsible for differences with age in estimates of the wage compensation an individual requires to accept increased occupational fatality risk. We derive a relationship between the value of a statistical life (VSL) and the degree of complementarity between consumption and labor supplied when health status serves as a potential source of variation in this relationship. Our empirical analysis finds that variations in an individual’s health status or quality of life and anticipated longevity threats lead to significant differences in the estimated wage/risk tradeoffs. We describe how extensions to the specification of hedonic wage models, including measures for quality of life and anticipated longevity threats, help to explain the diversity in past studies examining how the estimated wage–risk tradeoff changes with age.      

Has Devolution Injured American Workers? State and Federal Enforcement of Construction Safety

Although the issue of regulatory devolution has received muchscholarly scrutiny, rigorous empirical studies of its effectson important policy outcomes are scarce. This article exploresthe effects of partial regulatory devolution in the occupationalsafety arena by exploiting a unique historical anomaly wherebysome US states enforce protective labor regulations that areenforced elsewhere by the federal Occupational Safety and HealthAdministration. Analyzing data from the construction industry,this article contains several important findings. First, stateinspectors use traditional enforcement tools more sparinglythan their federal counterparts, typically citing fewer violationsand collecting lower fines per violation. Second, although federalenforcement significantly lowers the estimated frequency ofnonfatal construction injuries, it also predicts a significantincrease in occupational fatalities. I suggest that althoughhigher underreporting of nonfatal injuries in federally regulatedstates could explain this puzzling finding, it is equally possiblethat different regulatory styles have different "comparativeadvantages" in deterring nonfatal injuries on one hand and occupationalfatalities on the other.
