The average level of cost inefficiency in New York nursing homes is estimated at 29%, based on a two-year panel of 164 Skilled Nursing Facilities and 443 combination Skilled and Health Related Facilities. The stochastic frontier cost function is fit to the data utilizing the composed error model, wherein statistical noise and allocative and technical inefficiency are jointly estimated. There is no change in efficiency between 1987 and 1990, and it does not vary between for-profit and not-for-profit homes. Excessive managerial and supervisory personnel and diseconomies of size are linked to inefficient operation. Chronic excess demand is suggested as a cause of the high level of inefficiency.
基于由164家专业护理机构和443家专业与健康相关综合机构组成的为期两年的样本，纽约养老院的平均成本无效率水平估计为29%。利用复合误差模型将随机前沿成本函数与数据拟合，其中统计噪声以及配置和技术无效率是联合估计的。1987年至1990年间效率没有变化，营利性和非营利性养老院之间也没有差异。管理人员和监督人员过多以及规模不经济与运营效率低下有关。长期过度需求被认为是无效率水平高的一个原因。
