Global Disaster Risk Matters
构建了一个基于新闻的灾难风险指数，发现该指数能有效预测国际市场的股票及其他资产收益，并证实全球共同灾难风险是资产价格波动的重要驱动因素。
This article examines the cross-country asset pricing implications of disaster risk concerns. We construct a new disaster risk index, relying on six news-implied rare disaster proxies of Manela and Moreira (2017) , and show that this index is a powerful predictor for stock returns and other asset returns in international markets both in and out of sample. By further disentangling a global common component from our rare disaster index, we find evidence supporting theories that emphasize globally shared disaster risk as the important driving force of asset price fluctuations. Moreover, we conduct a return decomposition analysis and find that the global disaster risk drives stock returns primarily through the discount rate channel.
