| Summary/Abstract |
Does extreme heat have causal effects on exports? If so, how do the effects evolve? This paper exploits monthly fluctuations in the number of extremely hot days within a city to identify their effects on firm-level exports in that city. We find robust evidence that hot temperatures have persistent adverse effects on firm-level exports. Specifically, export losses gradually arise following a heat shock, beginning from an undetectable impact and eventually accumulating to a large and significant impact. An additional >30 °C day in a month could generate cumulative losses up to 0.83% of a firm's annual exports twenty-four months later. The negative effects of extreme heat are mainly through its adverse impacts on the firm's investment, capital, and production output. Capital-intensive sectors and FDI-related enterprises are among the most affected by high temperatures. Our findings support the “no-recovery” hypothesis after weather extremes and have implications for future climate change policies.
