Despite the growth in health insurance products that differentially cover preventive care and nonpreventive care, little is known about how preventive care utilization responds to targeted changes in coverage. Using administrative data from a large company, this paper examines the implementation of an insurance benefit design which differentially increased the price of nonpreventive care while decreasing the price of prevention. Leveraging a difference-in-differences research strategy, we find that preventive care utilization did not increase and even declined due to the differential price change. This evidence indicates a meaningful negative cross-price effect, suggesting that nonpreventive care and preventive care are complements.
尽管差异化涵盖预防性护理和非预防性护理的健康保险产品有所增加，但对于预防性护理的使用如何应对有针对性的保险范围变化，我们知之甚少。本文利用一家大公司的行政数据，研究了一种保险福利设计的实施情况，该设计在提高非预防性护理价格的同时降低了预防性护理的价格。利用双重差分研究策略，我们发现，由于价格差异变化，预防性护理的使用并未增加，甚至有所下降。这一证据表明存在显著的负交叉价格效应，表明非预防性护理和预防性护理是互补品。
