Measuring Welfare from Ambulatory Surgery Centers: A Spatial Analysis of Demand for Healthcare Facilities
研究了医院与日间手术中心在门诊手术市场的竞争，通过多项逻辑模型估算消费者需求，发现完全取消日间手术中心会导致每例手术福利损失10.2至28.1分钟。
This paper studies competition between healthcare facilities, particularly between hospitals and ambulatory surgery centers ( ASC 's), in the market for outpatient surgery. The goal is to answer questions about the existence and magnitude of welfare gains earned from the use of ASC 's. These questions are relevant to current policy debates about the usefulness of ASC 's. I calculate welfare by specifying a multinomial logit model of consumer demand for healthcare facilities, and estimating structural elements of demand functions. Total elimination of ASC 's results in between 10.2 and 28.1 minutes of welfare loss per patient surgery.
