内 容:It is well known that physicians respond to financial incentives, which can distort patients’ health care utilization. However, it is less known that how patient char-acteristics affect physicians’ decision-making. We make use of a natural experiment arising from a drug markup reduction policy to investigate how physicians respond to financial incentives differentially with expert and non-expert patients. With 100% in-patient claim data from a Chinese city, we first document that the policy reduces drug utilization while increases utilization of other forms of care. As a results, total costs increase, yet there is no improvement in health outcomes. However, such distortion in care is almost solely borne by non-expert patients. Compared to non-experts, different- hospital expert patients have 11% lower costs, and same-hospital expert patients have 20% lower costs. Furthermore, same-hospital higher-ranked expert patients have the lowest costs, 30% lower than non-experts。
