We explore the effects of health and healthcare utilization on household saving and financial portfolios using data from the Japanese Household Panel Survey and the Keio Household Panel Survey. Poor psychological well-being is found to be associated with lower levels of savings and smaller financial portfolios, whereas associations with poor physical health are largely absent. Significantly, our findings do not support the hypothesis that poorer physical health is associated with savings accumulation. In contrast, healthcare utilization in the form of hospital visits, hospitalization, and health screening is associated with greater savings and larger financial portfolios. This suggests that healthcare-based incentives to accumulate savings and financial wealth are related to channels associated with investment in health.

日本的家庭储蓄、健康和医疗保健利用

我们使用来自日本家庭小组调查和京王家庭小组调查的数据来探讨健康和医疗保健利用对家庭储蓄和金融投资组合的影响。研究发现，心理健康状况不佳与较低的储蓄水平和较小的金融投资组合有关，而与身体健康状况不佳的关联则基本不存在。值得注意的是，我们的研究结果不支持较差的身体健康与储蓄积累相关的假设。相比之下，医院就诊、住院和健康检查形式的医疗保健使用与更多的储蓄和更大的财务组合相关。这表明，基于医疗保健的积累储蓄和金融财富的激励措施与与健康投资相关的渠道有关。
