Employed for Higher Pay? How Medicare Payment Rules Affect Hospital Employment of Physicians
利用医疗保险对医院雇佣医生与其他医生的价格差异变化，研究发现支付规则解释了2009-2013年间医生雇佣增长的20%和医院门诊手术增长的75%。
Hospitals employ an increasing number of physicians and bill for a growing share of outpatient procedures. We exploit a plausibly exogenous increase in Medicare prices for hospital-employed physicians relative to Medicare prices for other physicians to show that payer reimbursement rules explain part of this trend. The shock we study explains 20 percent of the increase in physician employment and 75 percent of the increase in hospital-billed outpatient procedures between 2009 and 2013.
