This paper studies the impact of Thailand's Universal Health Coverage Scheme (UCS) on households' consumption and savings by using a synthetic panel data approach. Using difference-in-differences estimation, this study finds that, in the short run, the UCS had little or no impact on either households' savings or households' consumption expenditures. In the long run, the UCS still had no effect on savings (unless savings is defined to include consumption of durable goods), but there is evidence of an increase in consumption, especially consumption of durable goods. These effects are generally consistent with economic theory. The provision of health care coverage at little or no cost to previously uninsured households has an income effect that will increase both savings and consumption and a risk reduction effect that will reduce precautionary savings and thus increase consumption. These two effects on savings are of opposite sign and appear to cancel each other out, while both effects on consumption are positive and so appear to increase consumption, at least in the long run.
本文采用合成面板数据方法研究了泰国全民健康保险计划(UCS)对家庭消费和储蓄的影响。通过差分估计,本研究发现,在短期内,UCS对家庭储蓄或家庭消费支出几乎没有影响。从长期来看,UCS对储蓄仍无影响(除非储蓄被定义为包括耐用品消费),但有证据表明消费有所增加,尤其是耐用品消费。这些影响总体上与经济理论一致。向以前未参保的家庭提供几乎免费或免费的医疗保险会产生收入效应,这将增加储蓄和消费,同时还有降低风险效应,这将减少预防性储蓄,从而增加消费。这两种对储蓄的影响符号相反,似乎相互抵消,而对消费的两种影响都是积极的,因此至少从长期来看似乎会增加消费。
