Heterogeneous Firms under Regional Temperature Shocks: Exit and Reallocation, with Evidence from Indonesia
利用印度尼西亚企业数据，研究发现气温上升时低生产率企业更易退出，产出向高生产率企业重新配置，且幸存企业转向使用更多技能劳动和进口投入，揭示了气候变化对不同生产率企业的差异化影响及调整机制。
Are less productive firms in developing countries disproportionately affected by climate change? Using firm-level data from Indonesia, I find less productive firms are more likely to exit the surveys when temperature rises. Also, there is relative output redistribution to the initially more productive firms. The results are consistent with a heterogeneous firm model that has a skill-biased production function, where heat disproportionately affects unskilled labor productivity. Finally, surviving firms switched to use of more skilled labor and more imported inputs. These results illustrate how climate change affects firms of different initial productivity and how various margins of firm-level adjustment could mitigate such effects.
