Evaluating Mergers in the Presence of Dynamic Competition Using Impacts on Rivals Darren Filson (Robert Day School of Economics and Finance), Saman Olfati (Claremont McKenna College) & Fatos Radoniqi (Whittier College)
Abstract: We present evidence that event studies can help antitrust agencies forecast impacts of mergers on innovation. In large pharmaceutical mergers, cumulative abnormal returns on portfolios of rivals predict post-merger changes in the combined firm’s R&D intensity. More favorable impacts on rivals are associated with lower intensities, which is consistent with softening competition. Matching merging firms to similar non-merging firms suggests we can attribute the changes in R&D intensity to the mergers. We highlight the importance of deducting “expenses” associated with in-process R&D and provide guidance on how to define rivals, construct portfolios and use event studies in merger evaluations.
