Shocks to firm organization : the case of foreign acquisitions

This paper studies how foreign acquisitions affect firms’ internal labor organization, particularly occupational switching. This focus is inspired by new stylized facts we document using linked employer-employee data from Denmark: while the total number of occupations and hierarchical layers in firms remains stable, a significant share of firms simultaneously add and drop occupations and layers each year. Applying a dynamic two-way fixed effects matching estimator, we find that foreign acquisitions lead to significant reorganization within firms: though the number of layers or occupations remains unchanged, firms exhibit substantial occupational churning among existing workers, especially among higher-paid employees.
