- 요약This dissertation consists of three chapters in health economics, focusing on the behavior and strategy of healthcare providers, and consequent implications for medical spending and patient health.In Chapter 1, I use data on physicians' housing returns linked to their treatment choices and provide new empirical evidence on physicians' responses to wealth shocks. Specifically, I look at OBGYNs who have substantial discretion and significant financial incentives in choosing cesarean sections over vaginal deliveries. Using quasi-experimental variation in obstetricians' housing returns arising from the Great Recession, I find that the C-section rate as well as patients' length of stay and infection rate increase as obstetricians' housing returns decrease. Finally, in two policy evaluations, I show how physicians' sensitivity to wealth is useful in predicting changes in the C-section rate under an "across-the-board" fee cut and a transition from the Fee-For-Service to capitation model.In Chapter 2, Prof. Haizhen Lin and I study Group Purchasing Organizations (GPOs) within the U.S. hospital sector. Despite their prevalence in different contexts, the actual value of GPOs has been a subject of ongoing debate. Using various identification strategies, we consistently estimate that hospitals' supply expenses decrease in the GPO scale. We find no evidence that GPOs reduce supply expenses by compromising the quality of patient care or by altering the composition of patients. Instead, we identify that a portion of the cost savings is passed on to consumers through lower hospital prices, albeit primarily in highly competitive hospital markets.Chapter 3, co-authored with Prof. Haizhen Lin and Prof. Jia Xiang, studies physician behavior and its effects on patient outcomes. Specifically, we examine how one type of social movement, Black Lives Matter (BLM) protests, affects physicians' racial attitudes and their treatments on minority patients. We link the staggered outbreaks of BLM protests across U.S. cities to heart attack surgeries for Medicare patients. Using a stacked difference-in-differences specification combined with physician-fixed effects, we find that heart attack patients' mortality rates decrease following the protests. We don't observe any significant changes in measures of resource use, such as length of stay and the number of exams/tests. These results are consistent with the hypothesis that BLM protests raise physicians' awareness and motivate higher productivity without more input of care.
