摘要：

We study the implications of reference dependence in physicians’ preferences for healthcare, by leveraging a unique quasi-experiment: the 2015 reform for rehabilitation care in China. The reform results in an average increase in prices received by hospitals for some admission and a decrease for others. We find that the impact on medical expense differs depending on whether prices increase or decrease. To explain this finding, we develop a behavioral model with two novel features: (1) physicians have reference-dependent preferences; and (2) patients and physicians collectively maximize their joint utilities. Structural estimation of the model yields patterns consistent with our finding.
