Excess Demand, the Percentage of Medicaid Patients, and the Quality of Nursing Home Care
利用1979年威斯康星州数据，检验了养老院护理质量与医疗补助患者比例高相关的两种解释：是医疗补助报销率限制质量，还是超额需求消除了质量竞争的必要性。结果支持后者。
Most empirical studies of the determinants of the quality of nursing home care find a strong relationship between poor quality and a high percentage of Medicaid patients in the nursing home. These findings are often interpreted as evidence that the reimbursement rates paid for Medicaid patients are constraining nursing homes from providing higher quality care. Alternatively, this relationship can be attributed to the presence of excess demand eliminating the need to engage in quality competition for the less lucrative Medicaid patients. This paper tests these two hypotheses using Wisconsin data from 1979 and finds evidence favoring the latter.
