I. Introduction

1. Most modern anti-trust laws, both within the European Union and elsewhere, are built on a
trifecta of provisions: rules on agreements and concerted practices, rules on unilateral conduct
(or abuses of dominance), and rules on merger control.

2. The peculiarity of rules of merger control lies in the fact that, unlike the other two sets of rules,
they generally require the competent (administrative and/or judicial) authorities to engage in an
ex ante, as opposed to an ex post, form of review: whether a proposed concentration could, if
implemented, result in significant harm to effective competition. It is a particularly complex and
laborious technical evaluation, 'based not on the application of precise scientific rules but on
criteria and principles which are open to question', aimed at 'predicting the effects of the
concentration on the structure and competitive dynamics of the markets concerned, taking into
consideration the many  constantly evolving factors which may impinge  on  the future
development of supply and demand on those markets'.2
