This paper delves into the application of machine learning to forecast international stock returns based on firm characteristics. We reveal that market-specific training significantly enhances the performance of neural networks (NNs), as NNs trained on individual markets outperform those using a global model based on U.S. data. Our analysis shows that NNs

Weather risk, amplified by climate change, is posing an increasingly severe threat to agricultural production. Index insurance is a promising tool to hedge against weather risk, but traditional contracts face key limitations. Tapping into recent advances in machine learning, HKUST’s Zhanhui Chen and colleagues introduce a novel method of managing weather

Climate change and weather risk affect economy and livelihood over large scales, especially for agricultural production which depends on weather conditions. For example, United States Department of Agriculture estimates that 70-90\% of agricultural production loss can be attributed to adverse weather. In practice, weather index insurance can be employed to
