A Note on Merger and Acquisition Evaluation

  • Benjamin Furlan
  • Harald Oberhofer
  • Hannes Winner


This note proposes the continuous treatment approach as a valuable alternative to propensity score matching for evaluating economic effects of mergers and acquisitions (M&As). This framework allows to consider the variation in treatment intensities explicitly, and it does not call for the definition of cut-off values in traded ownership shares in order to construct a binary treatment indicator. We demonstrate the usefulness of this approach using data from European M&As and by relying on the example of post-M&A employment effects.
