Exporters under foreign heat
利用1995-2009年法国企业层面海关数据，估计外国天气冲击对出口的影响，发现平均影响虽小但大企业受负面冲击更严重，需求侧机制是主因。
Abstract In this article, I estimate the effect of foreign weather shocks on firm-level exports, exploiting the French firm-level customs data from 1995 to 2009. I find support for a small, negative impact of foreign temperatures on average but estimate a robust and strong differential effect across exporters, leading to composition changes. Larger firms are more negatively harmed by foreign weather shocks than small exporters. Regarding mechanisms, demand-side mechanisms (such as import demand changes) are mainly at play, whereas I find no evidence for supply-side (competition) mechanisms.
