Abstract

This paper relaxes the Motta & Vasconcelos’ (2005) short-term assumption that firms’ capital is fixed. We demonstrate that, contrary to the conclusion of that article, in the best interest of consumers, even when firms have large economies of scale, long-term forward-looking Antitrust Authorities must block firms’ merger plans whenever profits of firms are positive.
