The Effects of Market Concentration and Excess Demand on the Price of Nursing Home Care
研究了限制养老院床位数量的政策（如需求证明法和建设暂停令）如何通过提高市场集中度和造成超额需求，推高私人护理价格，并可能间接增加医疗补助支出。
Certificate-of-need laws and construction moratoria are policies designed to control government expenditures by limiting the number of nursing home beds in an area. These policies also represent barriers to entry and can result in excess demand. This study investigates the effect of market concentration and excess demand on private prices for nursing home care. The author finds evidence that both factors are associated with higher prices. Because higher prices may cause private patients to exhaust their financial resources and become Medicaid patients sooner than they otherwise would, these policies may have had indirect cost-increasing consequences.
