New Estimates of Disability-Related Wage Discrimination with Controls for Job Demands

Using data from 2004 SIPP, matched to job demands from O*Net, we provide new estimates of disability-related wage discrimination. We apply state-of-the-art econometric methods to wage models which include job demands and interactions between demands and functional limitations. The interaction terms are interpreted as measures of how well disabled workers ?match? to jobs which minimize the effects of functional limitations. The results suggest traditional discrimination models underestimate potential effects of disability-related discrimination by penalizing workers for limitations which may not affect their job performance. The bias is greater for men, who generally appear to find better matches than do women.Job demand; Disability; Wage Discrimination

Estimates of Wage Discrimination Against Workers with Sensory Disabilities, with Controls for Job Demands

We provide the first-ever estimates of wage discrimination against workers with sensory (hearing, speech, vision) disabilities. Workers with sensory disabilities have lower probabilities of employment and lower wages, on average, than nondisabled workers. Their poor labor market outcomes are explained, at least in part, by the negative productivity effects of sensory limitations in jobs that require good communication skills, but disabilityrelated discrimination may also be a contributing factor. To separate productivity vs. discrimination effects, we decompose the wage differential between workers with and without sensory disabilities into an ?explained? part attributed to differences in productivity-related characteristics, and an ?unexplained? part attributed to discrimination. The decomposition is based on human capital wage equations with controls for job-specific demands related to sensory abilities, and interactions between job demands and sensory limitations. The interactions are interpreted as measures of the extent to which a worker?s sensory limitations affect important job functions. The results indicate approximately 1/3 (1/10) of the disability-related wage differential for men (women) is attributed to discrimination. The estimates are quite different from estimates of discrimination against workers with physical disabilities obtained by the same methods, underscoring the importance of accounting for heterogeneity of the disabled population in discrimination studies.Job demand; Sensory disability; Wage discrimination

A Note on Job Mobility Among Workers with Disabilities

This article uses data from the 1990 and 1993 panels of the Survey of Income and Program Participation to analyze relationships between disability status and job mobility. We identify individuals who experienced voluntary or involuntary job separations over a 20-month period and examine the effect of disability status on rates of job change and wage growth following a job change. The results show that disabled workers are more likely to experience involuntary job changes than are nondisabled workers, but there is little difference in the wage effects of job changes by disability status

Patterns of sick-leave and health outcomes in injured workers with back pain

Little is known about the sick-leave experiences of workers who make a workers’ compensation claim for back pain. Our objective is to describe the 1-year patterns of sick-leave and the health outcomes of a cohort of workers who make a workers’ compensation claim for back pain. We studied a cohort of 1,831 workers from five large US firms who made incident workers’ compensation claims for back pain between January 1, 1999 and June 30, 2002. Injured workers were interviewed 1 month (n = 1,321), 6 months (n = 810) and 1 year (n = 462) following the onset of their pain. We described the course of back pain using four patterns of sick-leave: (1) no sick-leave, (2) returned to worked and stayed, (3) multiple episodes of sick-leave and (4) not yet returned to work. We described the health outcomes as back and/or leg pain intensity, functional limitations and health-related quality of life. We analyzed data from participants who completed all follow-up interviews (n = 457) to compute the probabilities of transition between patterns of sick-leave. A significant proportion of workers experienced multiple episodes of sick-leave (30.2%; 95% CI 25.0–35.1) during the 1-year follow-up. The proportion of workers who did not report sick-leave declined from 42.4% (95% CI 39.0–46.1) at 1 month to 33.6% (28.0–38.7) at 1 year. One year after the injury, 2.9% (1.6–4.9) of workers had not yet returned to work. Workers who did not report sick-leave and those who returned and stayed at work reported better health outcomes than workers who experienced multiple episodes of sick-leave or workers who had not returned to work. Almost a third of workers with an incident episode of back pain experience recurrent spells of work absenteeism during the following year. Our data suggest that stable patterns of sick-leave are associated with better health

\u3ci\u3eFundulus\u3c/i\u3e as the premier teleost model in environmental biology: Opportunities for new insights using genomics

A strong foundation of basic and applied research documents that the estuarine fish Fundulus heteroclitus and related species are unique laboratory and field models for understanding how individuals and populations interact with their environment. In this paper we summarize an extensive body of work examining the adaptive responses of Fundulus species to environmental conditions, and describe how this research has contributed importantly to our understanding of physiology, gene regulation, toxicology, and ecological and evolutionary genetics of teleosts and other vertebrates. These explorations have reached a critical juncture at which advancement is hindered by the lack of genomic resources for these species. We suggest that a more complete genomics toolbox for F. heteroclitus and related species will permit researchers to exploit the power of this model organism to rapidly advance our understanding of fundamental biological and pathological mechanisms among vertebrates, as well as ecological strategies and evolutionary processes common to all living organisms
