We examine the impact of economic policy uncertainty and geopolitical risk on various industries, highlighting their asymmetric effects on sectoral volatility. Furthermore, we investigate the differential effects of economic policy uncertainty and geopolitical risk on sectoral volatility, distinguishing between good and bad volatility responses. We find an asymmetric relationship between economic policy uncertainty and geopolitical risk in these industries, with economic policy uncertainty generally exerting a stronger impact on sector-specific volatility compared to geopolitical risk. During normal circumstances since the 2010s, the influence of geopolitical risk on sector-specific volatility has been relatively insignificant. However, both economic policy uncertainty and geopolitical risk have played significant roles in affecting multiple sectors during certain crisis periods, with geopolitical risk demonstrating short-term effects. These findings have important implications for both investors and policymakers. Investors can time positions using insights on policy uncertainty and geopolitical risk, while policymakers can identify vulnerable sectors.
We examine the impact of cultural differences on nominal share prices across 63 countries from 2002 to 2018. Using institutional and catering theories, we assess how cultural dimensions—including World Governance Indicators (WGI), legal systems, religious influences, and GLOBE dimensions—affect the spatial heterogeneity of share price levels. Our findings indicate that share prices are higher in countries with common law systems and comprehensive information reporting, as these environments tend to attract institutional investors. Conversely, cultural traits emphasizing altruistic values correspond with lower share prices, reflecting the preferences of individual investors.
