Systemic risk spillovers among global energy firms: Does geopolitical risk matter?
In recent years, the worsening global geopolitical conditions have led investors and policy makers to become increasingly concerned about systemic risk in the global energy market. However, the existing literature has little empirical evidence on this problem from a geopolitical perspective. Based on an Elastic-Net-VAR model for depicting high-dimensional left-tail interdependence, this paper measures time-varying systemic risk spillovers among 212 energy firms in 36 countries. Then, a panel data model is established to examine the impact of geopolitical risk (GPR) on risk spillovers. Our results indicate that the GPR of a country directly intensifies the risk spillovers of the country's energy firms, as well as spreads to other countries based on geographic proximity and energy trade flows and indirectly intensifies the risk spillovers of the energy firms in these countries. Specifically, the indirect effects of GPR are more pronounced than the direct effects for fossil fuel firms, in oil-consuming countries, and during stable periods in global geopolitics. Moreover, the potential firm-level mechanisms through which GPR intensifies risk spillovers are declines in asset turnover, deceleration in corporate investment, and negative market forecasts. These findings can help to mitigate the adverse effects of GPR on energy firm performance, national energy security, and stability in the global energy market.
期刊介绍:
Energy Economics is a field journal that focuses on energy economics and energy finance. It covers various themes including the exploitation, conversion, and use of energy, markets for energy commodities and derivatives, regulation and taxation, forecasting, environment and climate, international trade, development, and monetary policy. The journal welcomes contributions that utilize diverse methods such as experiments, surveys, econometrics, decomposition, simulation models, equilibrium models, optimization models, and analytical models. It publishes a combination of papers employing different methods to explore a wide range of topics. The journal's replication policy encourages the submission of replication studies, wherein researchers reproduce and extend the key results of original studies while explaining any differences. Energy Economics is indexed and abstracted in several databases including Environmental Abstracts, Fuel and Energy Abstracts, Social Sciences Citation Index, GEOBASE, Social & Behavioral Sciences, Journal of Economic Literature, INSPEC, and more.
