Labor market adjustment to extreme heat shocks: Evidence from Brazil
利用巴西雇主-雇员关联数据，研究了极端高温如何影响劳动力市场调整，发现季度热冲击增加制造业正式裁员概率，且工人跨部门和跨地区再配置有限，存在工作转换成本。
Despite ample evidence on the labor productivity impact of heat shocks, little is known about how heat shocks affect labor adjustment over time. This paper uses administrative employer–employee linked data from Brazil to examine margins of labor market adjustment to extreme heat. Tracking workers over time and across job spells, I find that quarterly heat shocks increase the probability of formal manufacturing layoffs. In the medium run, there is limited intersectoral and interregional reallocation, as well as a significant failure rate to reallocate back to formal sectors, indicating job transitional costs. Finally, the employment impact of heat shocks is larger for workers in more routine manual task intensive, less abstract occupations.
