我们估计了医疗保险D部分中处方药使用的价格弹性，该部分的特点是由于覆盖缺口而导致的非线性价格表。我们分析了覆盖缺口之前的药物利用模式，其中“有效价格”高于药物的实际自付费用，因为消费者预计更多的支出将使他们更有可能达到差距。我们发现，登记的总前差距的药物支出是敏感的，他们的有效价格：估计的价格弹性的药物支出范围在0.14和0.36之间。这一发现表明，按照2010年通过的医疗保健改革立法的要求，填补覆盖差距将影响差距之前的药物利用。模拟分析表明，缩小差距可能会使D部分的支出增加比预期更大的数额，而那些没有达到差距的人则会增加额外的差距前成本。
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 0.14 and 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.
