在November 2010的<Expect the Unexpected? Physicians’ Responses to Payment Changes>上,这可是大名鼎鼎的RAND的Mireille Jacobson和哈佛的Newhouse写的一篇小综述:
Economic theory tells us that the effect of fee cuts on physician effort depends on the share of income accounted for by the services whose fees are cut. On the one hand, a fee cut for one service can make other services or even leisure time more attractive to physicians, leading them to spend more of their time on these other activities and less on the
activity whose fee was cut. Economists term this response a substitution effect.
On the other hand, a fee cut for services that account for a large share of a physician’s practice can generate the opposite response: physicians may provide more of the service(s) to make up for some of the lost income. Economists call this response an income effect. How physicians respond to payment cuts depends critically on the balance between the substitution and income effects.
收入效应和替代效应的tradeoff在这里起作用。在他们描述的研究中,虽然单个或单次得到固定费用(fee)减少了,但是结果却是整个expending增加了。
