Methodologic issues in the use of workers' compensation databases for the study of work injuries with days away from work. I. Sensitivity of case ascertainment

Background Case ascertainment costs vary substantially between primary and secondary data sources. This review summarizes information on the sensitivity of state administrative databases in workers' compensation systems for the ascertainment of days-away-from-work (DAFW) work injuries for use in modeling studies. Methods Review of the literature supplemented by data from governmental or organizational reports or produced for this report. Results Employers currently appear to provide workers' compensation insurance coverage for 98.9% of wage and salary workers. Wage and salary jobs account for approximately 90% of jobs in the United States. In industries such as manufacturing, the fraction of covered jobs is probably closer to 98%. In Minnesota, the number of DAFW cases ascertained by the Bureau of Labor Statistics' annual survey of occupational injuries and illnesses is approximately 92–97% concordant with the number of wage compensation claims for injuries producing DAFW over the period 1992–2000, once adjustments are made to permit direct comparisons of the numbers. The workers' compensation databases provide information for more than 95% of the total DAFW resulting from work injuries. Covariate estimates are unaffected by this less than 5% loss because effects appear dependent on time from injury. Conclusions Statewide workers' compensation administrative databases can have substantial utility for epidemiologic study of work injuries with DAFW because of their size, using high sensitivity for case ascertainment as the evaluative criterion.

The impact of child SSI enrollment on household outcomes

We use data from the Survey of Income and Program Participation (SIPP) to investigate the impact that child Supplemental Security Income (SSI) enrollment has on household outcomes, including poverty, household earnings, and health insurance coverage. The longitudinal nature of the SIPP allows us to control for unobserved, time-invariant differences across households by measuring outcomes in the same household in the months leading up to and immediately following the first reporting of child SSI income. Our regression analyses demonstrate that for every $100 increase in household SSI income, total household income increases by roughly$72, reflecting some modest offset of other transfer income and conditional household earnings. Our analyses further demonstrate that child SSI enrollment is associated with a statistically significant and persistent reduction in the probability that a child lives in poverty of roughly 11 percentage points. Additional analyses suggest that program enrollment has virtually no impact on health insurance coverage because most new SSI recipients have health insurance from Medicaid or another source at the time of enrollment. © 2007 by the Association for Public Policy Analysis and Management

Cost containment in complex social security systems: the limitations of targeting

Book synopsis: Two aspects of the structure of existing social security systems limit the scope for containing costs by increasing targeting: the insurance principle, and the use of category membership to establish eligibility for benefits. The first aspect is antithetical to targeting because the most needy people are also the most likely to fail to establish an adequate contributions record. Some countries appear committed to maintaining the insurance principle because it is part of the fabric of the relationship between employers, employees and the State. The second aspect can be seen as an effective way of identifying groups whose income is likely to fall short of their needs. However, the primary function of category definition is to establish the legitimacy of claims—to examine why a shortfall of income in relation to needs has arisen, what personal responsibility the claimant bears, and what alternative mechanisms might be available. Several countries have revised category definitions in response to issues about the motivation and “deservingness” of claimants. We designate as “pseudo-targeting” reforms of this type, which are not likely to result in the allocation of a higher share of social expenditure to the worst-off. The scope for increasing targeting in existing systems is very restricted, reflecting the limitations of the concept. Non-categorical social assistance is the archetypal targeted benefit, and it has serious limitations. The obstacles to targeting are integral to the legitimation of social security. If targeting reforms undermine this legitimating structure, they risk undermining the claim on resources exercised by the social security system

The relationship between women’s work histories and incomes in later life in the UK, US and West Germany

Using data from several large-scale longitudinal surveys, this article investigates the relationship between the work histories and personal incomes (from both public and private sources) of older women in the UK, US and West Germany. By comparing three countries with different welfare regimes and pension systems, we seek to gain a better understanding of the interaction between the life course, pension system and women’s incomes in later life. The association between older women’s incomes and work histories is strongest in West Germany and weakest in the UK, where there is evidence of a ‘pensions poverty trap’ and where only predominantly full-time employment is associated with significantly higher incomes in later life. Work history matters less for widows (in all three countries) and more for recent birth cohorts and more educated women (UK only). The article concludes with a brief discussion of the treatment of women under different pension regimes assessed by the criteria of adequacy, proportionality, vertical equity and horizontal equity
