"By using a unique dataset on managerial-level employees who were transferred from Japan to European branches of the same global firms, we examine what would happen to work hours when a worker moves from a long-hour-working country to relatively shorter-hour countries. Even after controlling for business cycles, unobserved individual heterogeneity, job characteristics, and work hour regulations, we find a significant decline in Japanese work hours after their transfer to Europe, resulting from working-behavior influences of locally hired staff. We also find that the reduction in hours worked highly depends on the extent of the workers' interactions with local peers."
