Foreign acquisition and internal organization

Abstract

We study the effect of foreign takeovers on firm organization. Using a comprehensive data set of Portuguese firms and workers spanning two decades, we find that foreign acquisitions lead to: (1) an expansion in the scale of operations; (2) a higher number of hierarchical layers; (3) increased span of control among top managers; and (4) increased wage inequality across layers. These results accord with a theory of knowledge-based hierarchies in which foreign takeovers improve management practices and reduce communication costs within the acquired firms. Evidence from auxiliary survey data provides support to this mechanism by suggesting that acquired firms are more likely to use information technologies that reduce internal communication costs.
