The effect of retirement on healthcare utilization: Evidence from China
利用中国纵向数据和非参数模糊断点回归设计，发现退休增加了医疗利用，主要原因是健康恶化和时间机会成本降低，低收入教育群体更可能放弃住院治疗。
We examine the effect of retirement on healthcare utilization in China using longitudinal data. We use a nonparametric fuzzy regression discontinuity design, exploiting the statutory retirement age in urban China as a source of exogenous variation in retirement. In contrast to previous results for developed countries, we find that in China retirement increases healthcare utilization. This increase can be attributed to deteriorating health and in particular to the reduced opportunity cost of time after retirement. For the sample as a whole, income is not a dominating mechanism. People with low education, however, are more likely to forego recommended inpatient care after retirement.
