摘要

我们估计处方药在医疗保险D部分使用的价格弹性,其特点是非线性的价格表,由于覆盖差距。我们分析了覆盖缺口之前的药物使用模式,其中“有效价格”高于药物的实际共同支付,因为消费者预期更多的支出将使他们更有可能达到缺口。我们发现参保人的缺口前药品总支出对有效价格敏感:药品支出的估计价格弹性在[公式:见文]0.14和[公式:见文]0.36之间。这一发现表明,根据2010年通过的医疗改革立法,填补覆盖缺口将影响缺口之前的药物利用。一项模拟分析表明,缩小差距可能会增加D部分的支出,比预计的要多,而那些没有达到差距的人在差距前会有额外的成本。

Demand for prescription drugs under non-linear pricing in Medicare Part D.

We estimate the price elasticity of prescription drug use in Medicare Part D, which features a non-linear price schedule due to a coverage gap. We analyze patterns of drug utilization prior to the coverage gap, where the "effective price" is higher than the actual copayment for drugs because consumers anticipate that more spending will make them more likely to reach the gap. We find that enrollees' total pre-gap drug spending is sensitive to their effective prices: the estimated price elasticity of drug spending ranges between [Formula: see text]0.14 and [Formula: see text]0.36. This finding suggests that filling in the coverage gap, as mandated by the health care reform legislation passed in 2010, will influence drug utilization prior to the gap. A simulation analysis indicates that closing the gap could increase Part D spending by a larger amount than projected, with additional pre-gap costs among those who do not hit the gap.
