There has been much debate among economists about whether nursing home quality is a public good across Medicaid and private-pay patients within a common facility. However, there has been only limited empirical work addressing this issue. Using a unique individual level panel of residents of nursing homes from seven states, we exploit both within-facility and within-patient variation in payer source and quality to examine this issue. We also test the robustness of these results across states with different Medicaid and private-pay rate differentials. Across our various identification strategies, the results generally support the idea that quality is a public good within nursing homes. That is, within a common nursing home, there is very little evidence to suggest that Medicaid-funded reside...

Nursing home expenditures are a rapidly growing share of national health care spending with the government functioning as the dominant payer of services. Public insurance for nursing home care is tightly targeted on income and assets, which imposes a major tax on savings; moreover, low state reimbursement for Medicaid patients has been shown to lower treatment quality, and bed supply constraints may deny access to needy individuals. However, expanding eligibility, increasing Medicaid reimbursement, or allowing more nursing home bed slots has the potential to induce more nursing home use, increasing the social costs of long term care. A problem in evaluating this tradeoff is that we know remarkably little about the effects of government policy on nursing home utilization. We attempt to ...

This paper studies factor substitution in one important sector: the nursing home industry. Specifically, we measure the extent to which nursing homes substitute materials for labor when labor becomes relatively more expensive. From a policy perspective, factor substitution in this market is important because materials-intensive methods of care are associated with greater risks of morbidity and mortality among nursing home residents. Studying longitudinal data from 1991-1998 on nearly every nursing home in the United States, we use the method of instrumental variables (IV) to address the potential endogeneity of nursing home wages. The results from the IV models are consistent with the theory of factor substitution: higher nursing home wages are associated with lower staffing, greater use o...
