中文摘要
我们使用瑞典彩票玩家的行政数据来估计巨额财富冲击对玩家自身健康及其子女健康和发展结果的因果影响。我们的估计样本很大,几乎不存在流失,并且允许我们控制相关因素,在这些因素给定条件下奖品是随机分配的。在成年人中,我们没有发现财富影响死亡率或医疗保健利用率的证据,可能的例外是心理健康药物消费的少量减少。我们的估计允许我们排除对10年死亡率的影响达到横截面财富-死亡率梯度的六分之一那么大的可能性。在我们的代际分析中,我们发现财富增加了彩票开奖后几年中儿童的医疗保健利用率,也可能降低了肥胖风险。对大多数其他儿童结果(包括药物消费、学业表现和技能)的影响通常可以界定在零附近的一个紧凑区间内。总体而言,我们的研究结果表明,在拥有广泛社会安全网的富裕国家中,财富的因果效应不是财富-死亡率梯度的主要来源,也不是儿童发展结果与家庭收入之间观测到关系的主要来源。
Abstract
Abstract We use administrative data on Swedish lottery players to estimate the causal impact of substantial wealth shocks on players’ own health and their children’s health and developmental outcomes. Our estimation sample is large, virtually free of attrition, and allows us to control for the factors conditional on which the prizes were randomly assigned. In adults, we find no evidence that wealth impacts mortality or health care utilization, with the possible exception of a small reduction in the consumption of mental health drugs. Our estimates allow us to rule out effects on 10-year mortality one sixth as large as the cross-sectional wealth-mortality gradient. In our intergenerational analyses, we find that wealth increases children’s health care utilization in the years following the lottery and may also reduce obesity risk. The effects on most other child outcomes, including drug consumption, scholastic performance, and skills, can usually be bounded to a tight interval around zero. Overall, our findings suggest that in affluent countries with extensive social safety nets, causal effects of wealth are not a major source of the wealth-mortality gradients, nor of the observed relationships between child developmental outcomes and household income.
