中文摘要
我们使用1996—2019年瑞士职业事故行政数据，研究气温对职业健康的影响。结果表明，相较于温和天气，炎热天气（最高气温≥30°C）的职业事故数量增加7.4%，冰冻天气（最高气温<0°C）则增加6.3%。我们发现，极端气温平均每年导致2,600起工作场所事故，每年造成9,100万瑞士法郎的损失。我们提供了提示性证据，表明炎热天气下睡眠不足是其作用机制之一。尽管极端气温会损害职业健康，但我们观察到大多数劳动者的劳动供给调整有限。
Abstract
We study the effects of temperature on occupational health using administrative data on Swiss occupational accidents from 1996 to 2019. Our results imply that on hot days ( T m a x ≥ 30 °C) the number of occupational accidents increases by 7.4% and on ice days ( T m a x < 0 °C) by 6.3%, relative to mild days. We find that extreme temperatures cause an average of 2600 workplace accidents each year, costing CHF 91 million annually. We provide suggestive evidence for insufficient sleep on hot days as a mechanism. While extreme temperatures worsen occupational health, we observe limited labor supply adaption for most workers.
