In this paper we will examine the issue of ownership unbundling and forced divestiture remedies imposed in a series of recent competition law cases of the energy market - examined in other papers - in relation to the possible existence of a series of legal obstacles. These energy market...

In this paper we investigate the anti-competitive effects of partial horizontal ownership in a setting where: (i) two cost-asymmetric firms compete à la Cournot; (ii) managers deal with eventual conflicting interests of the different shareholders by maximizing a weighted sum of firms' operating...

Many Internet intermediaries operate two-sided networks, that is, they provide platforms to bring together two types of participants, or quot;sides,quot; such as buyers and sellers. This paper develops a model that characterizes the intermediary's pricing in two-sided networks, the value created...

Minority shareholdings have been on the regulatory agenda of competition authorities for some time. Recent empirical studies, however, draw attention to a new, thought provoking theory of harm: common ownership by institutional investors holding small, parallel equity positions in several...

Private equity firms (PE firms) have become common owners of established firms in concentrated markets. We show that the threat of a PE acquisition can trigger incumbent mergers in an otherwise mergerstable industry. This can help antitrust authorities maximize consumer surplus because...

Horizontal shareholdings exist when a common set of investors own significant shares in corporations that are horizontal competitors in a product market. Economic models show that substantial horizontal shareholdings are likely to anticompetitively raise prices when the owned businesses compete...
