Wealth Accumulation and Health Accumulation

笔者使用日本的各种个人数据，对财富积累与健康积累的关系进行了实证分析。主要结果如下。首先，个人对时间和风险的偏好是决定预防行为的重要因素，这确实会改变健康状况。第二，与健康有关的活动，如准备食物，可能会受到母亲的劳动力参与中下阶层的干扰。第三，父母失业恶化了新生儿的健康状况。第四，财富与健康的关系不是简单的相关关系，而是从更多的财富到更好的健康的真实的因果关系。

I conducted several empirical analyses on the relationship between wealth accumulation and health accumulation, using different kinds of Japanese individual data. The main results are as follows. First, individual preferences for time and risk are the important factors determining precautionary behaviors, which indeed changes health status. Second, the health-related activities, say food preparation, may be disturbed by mother' s labor force participation in lower middle classes. Third, parent' s unemployment deteriorates health condition of newborn babies. Fourth, the relationship between wealth and health is not a simple correlation, but a real causation from more wealth to better health.
