Global geopolitical risk and corporate ESG performance.

This study investigates whether and how the global geopolitical risk (GPR) impacts the environmental, social, and governance (ESG) performance of Chinese enterprises utilizing panel data of Chinese A-share listed enterprises from 2011 to 2020. The findings show that enterprises' ESG performance is negatively impacted by the global GPR. According to heterogeneity analysis, the global GPR has a more detrimental effect on ESG performance in non-state-owned enterprises, enterprises in the decline period, enterprises with higher institutional investor shareholdings, and enterprises without political connections. Additional mechanism analysis reveals that global GPR primarily weakens Chinese enterprises' ESG performance by increasing their financing constraints and reducing competitiveness. . In conclusion, our main findings are still valid after addressing endogeneity-related concerns and doing robustness tests.

Optimal risk management considering environmental and climatic changes.

Climate change presents challenges to policy and economic stability, necessitating effective trading strategies to reduce environmental risks. This article addresses gaps in existing studies by using a Markov-switching model to consider climate risk. Backward stochastic differential equations are used to optimize utility with three hedging strategies based on the concept of risk aversion. Numerical scenarios confirm the model's superiority in incorporating exogenous events, with our risk-averse strategy outperforming classical approaches. Our strategy outperforms classical strategies by taking a flexible risk trading when investors face risk-averse behavior due to climate risk events. The findings presented in this article have important implications for the development of more resilient investment portfolios and can contribute to climate policy.
