以前的研究估计了香烟价格对身体质量指数（BMI）的平均影响，最近的研究表明，他们不同的方法都指向几年后的负面影响。然而，这篇文献忽略了这样一种可能性，即由于基础肥胖风险或健康偏好的差异，这种影响可能在整个BMI分布或社会经济和人口统计学群体中有所不同。我们通过分位数回归和按种族、教育、年龄和性别对样本进行分层，评估香烟价格对BMI长期影响的异质性。香烟价格具有高度异质性的负面影响，在高BMI水平下-减肥对健康最有益-比低BMI水平下强三倍以上。对黑人、大学毕业生、中年人和女性的影响也最大。我们还评估差异的影响，进行健壮性检查，并评估潜在的机制。
Previous studies estimate the average effect of cigarette price on body mass index (BMI), with recent research showing that their different methodologies all point to a negative effect after several years. This literature, however, ignores the possibility that the effect could vary throughout the BMI distribution or across socioeconomic and demographic groups due to differences in underlying obesity risks or preferences for health. We evaluate heterogeneity in the long-run impact of cigarette price on BMI by performing quantile regressions and stratifying the sample by race, education, age, and sex. Cigarette price has a highly heterogeneous negative effect that is more than three times as strong at high BMI levels – where weight loss is most beneficial for health – than at low levels. The effects are also strongest for blacks, college graduates, middle-aged adults, and women. We also assess the implications for disparities, conduct robustness checks, and evaluate potential mechanisms.
