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 ... 阅读更多

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 ... 阅读更多

The interest rate charged on business loans, known as the discount rate, affects stock prices. This is particularly important, given the fast rate increases by the Federal Reserve this year.

Nevertheless, changes in life expectancy can be rather volatile, with negative shocks occurring from economic recessions, epidemics, natural disasters, wars, and social and political disturbances. In the United States ... 阅读更多

Climate change threatens human societies with long-term catastrophic consequences. These threats must be addressed immediately. A delayed response to climate change will lead to further deterioration and a greater chance of irreversible and catastrophic damage. In this article, we discuss the possibility of using weather derivatives to manage climate ... 阅读更多
