Hospital Competition and Quality with Regulated Prices*
分析了在价格管制下，引入竞争和增加竞争强度对医院质量的影响，发现两者关系不确定，这与理论文献的预期不同，但能解释实证研究中的混合结果。
Abstract We analyse the effect of competition on quality in hospital markets with regulated prices, considering the effect of both introducing competition (monopoly versus competition) and increasing competition through either lower transportation costs (increased substitutability) or a higher number of hospitals. With semi‐altruistic providers and a fairly general cost structure, we show that the relationship between competition and quality is generally ambiguous. In contrast to the received body of theoretical literature, this is consistent with, and potentially explains, the mixed empirical evidence.
