We estimate the spillovers on firm profitability and market shares in oligopolistic markets through the transition from an n to an n-1 player oligopoly after a merger in the industry. Competitors are identified via the European Commission s market investigations and our methodology allows us to...

We quantify externalities on profitability and market shares of competing firms in oligopolistic markets through the transition from an n to an n - 1 player oligopoly after a merger. Competitors are identified via the European Commission's market investigations and our methodology allows us to...

We analyze evidence production in merger control as a delegation problem under an inquisitorial and an adversarial competition policy system. Agents' incentives to produce evidence depend critically on the action set of the decision maker. In an inquisitorial system, allowing ex ante for a...

This paper analyzes the effects of mergers and acquisitions on the markups of non-merging rival firms across a broad set of industries. We exploit expert market definitions from the European Commission's merger decisions to identify relevant competitors in narrowly defined product markets....

The European market has been served by regulated and licensed e-money tokens (EMTs) since 2019, contradicting the claim that legal clarity is needed for EMTs. Despite the well-functioning e-money legislation, the EU Parliament will vote on a new regulation specifically for EMTs as part of the...

This article analyzes endogenous efficiency gains from mergers. It considers oligopolistic homogeneous good markets and duopolistic and triopolistic markets under product differentiation (PD) (quantity and price competition). In a two-stage game, firms invest in cost-reducing innovation with and...

Under EU competition law it is prohibited to conclude anti-competitive agreements. If found, such conduct warrants fines in the millions. How-ever, little guidance on what to consider restrictive practices are available from the relevant statute, referring the matter to case law. Here a pattern...

The literature shows that horizontal shareholding engenders significant anticompetitive effects and that no suitable instrument exists within European competition law which reliably and effectively can be applied to curtail such intrinsic effects. This Article analyses several proposals which...

This paper explores, both theoretically and empirically, the impact of granting antitrust immunity (ATI) to airline alliances in a novel and realistic framework characterized by vertically-differentiated air services. Our theoretical model suggests that non-ATI alliances produce an up-market...

Bigness as such is not an offence in the EU. Nonetheless, in several EU- and Non-EU-jurisdictions there exist powers to order the breaking up of large firms if this is deemed necessary to remedy adverse effects on competition even if they were not created by an unlawful merger or by abusive...
