Abstract
This paper investigates the indirect cost of stock market participation using administrative data from a large Chinese hospital covering about four million patient visits. In addition to the well-established negative health implication of stock market decline on stockholding patients, we show that in settings where patients have little impact, market fluctuations in either direction worsen medical outcomes, as shown by increased outpatient revisits and poor surgical wound healing. This effect is highly transitory, driven by extreme market turmoil, accompanied by signs of physicians’ deteriorated clinical practice, and matches the dynamics of retail investors’ attention to the market.
中文摘要:本文利用我国某三甲医院余约400万患者的行政大数据,考察了股事参与的间接成本。我们不仅复现了文献中股市下跌对投资者健康的负向作用,也发现了在患者难以影响医疗成效的情境下,股市的正负双向波动均导致了复诊率和手术不良伤口愈合率升高等医疗成效恶化的现象。该现象是短暂的,由极端股市波动驱动,伴随着医生医疗行为的恶化,并与散户对股市关注度的动态紧密相关。
