The wealth effects of takeover bids regulation in the European Union.

We investigate the wealth effects of the Takeover Bids Directive, enacted by the European Union (EU), on mergers and acquisitions. The directive aims at protecting target minority shareholders by restricting antitakeovers provisions and preventing managerial entrenchment. We test the regulation impact using a treatment sample of EU public acquisitions and a control sample from outside the EU. Our results suggest diverse effects of the regulation across treatment countries: acquirers from countries with better shareholder protection engage in more value‐enhancing acquisitions postregulation that could otherwise be too costly. The regulation also increases the likelihood of firms becoming targets and raises market value. [ABSTRACT FROM AUTHOR]
