This paper estimates the impact of social health insurance on financial risk by utilizing data from a natural experiment created by the phased roll-out of a social health insurance program for the poor in India. We estimate the distributional impact of insurance on of out-of-pocket costs and incorporate these results with a stylized expected utility model to compute associated welfare effects. We adjust the standard model, accounting for conditions of developing countries by incorporating consumption floors, informal borrowing, and asset selling which allow us to separate the value of financial risk reduction from consumption smoothing and asset protection. Results show that insurance reduces out-of-pocket costs, particularly in higher quantiles of the distribution. We find reductions in the frequency and amount of money borrowed for health reasons. Finally, we find that the value of financial risk reduction outweighs total per household costs of the insurance program by two to five times.
本文利用印度逐步推出针对贫困人口的社会医疗保险计划所产生的自然实验数据,估计了社会医疗保险对财务风险的影响。我们估计了保险对自付费用的分配影响,并将这些结果与一个简化的期望效用模型相结合,以计算相关的福利效应。我们调整了标准模型,通过纳入消费下限、非正式借贷和资产出售来考虑发展中国家的情况,这使我们能够将财务风险降低的价值与消费平滑和资产保护区分开来。结果表明,保险降低了自付费用,特别是在分布的较高分位数上。我们发现,由于健康原因而借款的频率和金额都有所减少。最后,我们发现,财务风险降低的价值是保险计划每户总成本的两到五倍。
