CEO power, bank risk-taking and national culture: International evidence

Using unique hand-collected data for 336 large banks across 48 countries, together with values of national culture, our empirical analysis uncovers three new robust findings. First, variations of bank risk-taking across national culture and CEO power are more pronounced when cultural values and CEO power indicators are high. Second, while the individualism dimension of national culture has a moderating influence, the uncertainty avoidance dimension has a reinforcing effect, on the relationship between CEO power and bank risk-taking. In more detail, the results for the average marginal effect of CEO power on risk for different cultural values show that CEO power has a negative (positive) or insignificant impact on bank risk-taking when the value of individualism (uncertainty avoidance) is low; however, the impact becomes positive (negative) and statistically significant as the value of individualism (uncertainty avoidance) increases. Third, intra-cultural diversity matters: 'tight' cultures (e.g., strong social norms) are more pronounced than 'loose' cultures (e.g., heterogeneous values) in influencing bank risk.
