We examine the average effect of the affordable care act (ACA) Medicaid expansion on cigarette consumption as well as heterogeneous effects by consumer types, depending on whether they use anti-smoking products and their baseline level of cigarette consumption. Using the Nielsen homescan consumer panel and generalized difference-in-differences (GDD) method, we find that anti-smoking products can induce cigarette smoking among moderate and heavy smokers. However, the ACA Medicaid expansion reduces cigarette smoking through channels other than anti-smoking products. As a net result, the ACA Medicaid expansion leads to a reduction in smoking. Light smokers are the main beneficiaries of ACA Medicaid expansion—their average cigarette consumption reduces by over one pack per month.

平价医疗法案医疗补助扩张如何影响卷烟消费？——机制和异质性

我们检查了负担得起的医疗法案 (ACA) 医疗补助扩展对卷烟消费的平均影响以及消费者类型的异质影响，这取决于他们是否使用反吸烟产品和他们的卷烟消费基线水平。使用 Nielsen homescan 消费者小组和广义差异中的差异 (GDD) 方法，我们发现禁烟产品可以诱导中度和重度吸烟者吸烟。然而，ACA 医疗补助计划的扩展通过反吸烟产品以外的渠道减少了吸烟。最终结果是，ACA 医疗补助计划的扩展导致吸烟减少。轻度吸烟者是 ACA 医疗补助扩张的主要受益者——他们的平均卷烟消费量每月减少一包以上。
