This paper focuses on geopolitical risk (GPR) related to wars, terrorist acts, and tensions between states. Evidence is provided to demonstrate that GPR is different from other economic, financial, and political risks measured in the literature and that this research could therefore be helpful to investors with respect to geopolitical tensions in particular.
