Acquisition Integration and Productivity Losses in the Technical Core: Disruption of Inventors in Acquired Companies

Abstract

Acquisition integration is a pivotal factor in determining whether the objectives of an acquisition are achieved. In this paper, we hypothesize that the productivity of corporate scientists of acquired companies is generally impaired by integration, but that some scientists experience more disruption than others. In particular, acquisition integration will be most disruptive, leading to the most severe productivity drops, for those inventors who have lost the most social status and centrality in the combined entity. Drawing from prior literatures on the knowledge-based view of the firm, and on mergers and acquisitions, we develop hypotheses about a concise set of conditions that will lead to substantial performance drops for acquired technical personnel. We test our hypotheses, using patent application data, on a sample of 3,933 inventors in pharmaceutical firms whose companies were acquired. Results are strongly in line with our theorized expectations.
