The demand inducement hypothesis predicts that physicians will respond to reductions in their income by increasing the volume of their services when the income effect is strong and negative. I test for such inducement in the market for coronary artery bypass grafting (CABG), using a longitudinal panel of physicians in New York and Washington states. The results show that physicians whose incomes were reduced the most by Medicare fee cuts performed higher volumes of CABGs, and they did so in both the Medicare and private markets.
需求诱导假说预测，当收入效应强烈且为负时，医生会通过增加服务量来应对收入减少的情况。我利用纽约州和华盛顿州医生的纵向面板数据，对冠状动脉搭桥术（CABG）市场中的这种诱导行为进行了检验。结果表明，那些因医疗保险费用削减而收入减少最多的医生进行了更多的冠状动脉搭桥手术，而且在医疗保险市场和私人市场都是如此。
