Abstract

This paper takes a new look at the effects of mergers on innovation by analysing the relationship between ex-ante technological (and product) relatedness of acquirers and targets and post-merger performances. The analysis is conducted using data on consolidations in the pharmaceutical industry for the period 1988-2004. Empirical results show that merger deals are more likely to be signed between firms with related technologies and drug portfolio. I .find that merged companies have on average, worst performances than the group of non-merging firms and that, contrary to what may be the common wisdom, higher levels of technological relatedness are associated with poorer performances. Finally, consolidations between large pharmaceutical companies seem to have a detrimental impact on the incentives of competitors to undertake research in those therapeutic areas where both acquirer and target are active players.
