Temperature Shocks and Establishment Sales
结合美国日度温度数据和企业数据，研究发现温度冲击对企业销售额和生产率没有显著影响，包括传统“热敏感”行业，支持了富裕国家温度与经济增长关系薄弱的结论。
Abstract Combining granular daily data on temperatures across the continental United States with detailed establishment data from 1990 to 2015, we study the causal impact of temperature shocks on establishment sales and productivity. Using a large sample yielding precise estimates, we do not find evidence that temperature exposures significantly affect establishment-level sales or productivity, including among industries traditionally classified as “heat sensitive.” At the firm level, we find that temperature exposures aggregated across firm establishments are generally unrelated to sales, productivity, and profitability. Our results support existing findings of a tenuous relation between temperature and aggregate economic growth in rich countries.
