“Specialized Investments and Firms’ Boundaries: Evidence from Textual Analysis of Patents”
Michael Weisbach
Fisher College of Business (Ohio State University) – joint work with Jan Bena, Isil Erel and Daisy Wang


Inducing firms to make specialized investments through bilateral contracts can be challenging because of potential hold-up problems. Such contracting difficulties have long been argued to be an important reason for acquisitions. To evaluate the extent to which this motivation leads to mergers, we perform a textual analysis of the patents filed by the same lead inventors of the target firms before and after the mergers. We find that patents of inventors from target firms become 15% to 20% more similar to those of acquirers’ inventors following completed mergers, benchmarked against patents filed by targets and a group of counterfactual acquirers. This pattern is stronger for vertical mergers that are likely to require specialized investments. There is no change in the similarity of patents for mergers that are announced but not consummated. Overall, we provide evidence suggesting that contracting issues in motivating specialized investment can be a motive for acquisitions.

To attend please submit the survey no later than Tuesday 18th at 4:00 p.m. The link to the webinar will be provided by email on the day before.


We are looking forward to seeing you there.
Kind regards,
Miguel Sousa
