This paper examines the influence of managers from countries with different gender norms on workplace culture and gender disparities within organizations. Using data from a multinational firm operating in over 100 countries, we exploit cross-country manager rotations to estimate the impact of male managers’ gender attitudes on gender pay gaps within a team. Managers from countries with one standard deviation more progressive gender attitudes narrow the pay gap by 5 percentage points (18%), primarily by promoting women at higher rates. The effects last beyond the manager’s rotation and are concentrated in countries with more conservative gender attitudes. Managers with progressive views appear to influence the local office culture, as local managers who interact with but are not under the purview of the foreign manager begin to have smaller pay gaps in their teams. Our evidence points to individual managers as critical in shaping corporate culture.
