Advances in competition economics as well as in computational and empirical methods have offered the scope for the employment of merger simulation models in merger control procedures during the past almost 15 years. Merger simulation is, nevertheless, still a very young and innovative instrument...

Advanced economic instruments like simulation models are enjoying an increased popularity in practical antitrust. There is hope that they being quantitative predictive economic evidence can substitute for qualitative structural analysis and lead to unambiguous results. This paper demonstrates...

We find that stricter merger control legislation increases abnormal announcement returns of targets in bank mergers by 7 percentage points. Analyzing potential explanations for this result, we document an increase in the pre-merger profitability of targets, a decrease in the size of acquirers...

We consider antitrust enforcement within the adversarial model used by the United States. We show that, under the adversarial system, the Antitrust Authority may try to prohibit mergers also in those cases in which litigation is inefficient. Even if market concentration and technological...

From the beginning, the debate on the likely results of the proposed acquisition of T-Mobile USA by AT&T focused more on the claims of the parties that “immense” merger efficiencies would overwhelm any apparent losses of competition than on the presence or absence of those losses, and the...

Efficiency defence and merger remedies are key components in most merger control regimes. Although in many jurisdictions both the provision of efficiency-related evidence and remedy offers are at the merging firms' discretion, most previous works have only analysed them separately. This paper is...

This article addresses the application of the economic literature on merger simulation to the practical context of antitrust enforcement. It highlights the value of simple simulations as a basis for creating screens and presumptions – particularly the gross upward pricing pressure index for...

Private equity firms have become common owners of established firms in concentrated markets. Antitrust authorities therefore intervene in mergers and acquisitions involving PE firms. In this article, we discuss the antitrust implications of an active PE market and whether there are any special...
