We study the evolution of EC merger decisions over the first 25 years of common European merger policy. Using a novel dataset at the level of the relevant antitrust markets and containing all merger cases scrutinized by the Commission over the 1990-2014 period, we evaluate how consistently...

Les décisions de l'Autorité de la concurrence en matière de contentieux ou de concentration sont publiques. Pourtant elles sont, selon le lectorat, soit trop techniques, soit pas assez. En effet, il paraît difficile de soutenir qu'un citoyen, fut-il même chef d'entreprise, soit en mesure de...

This short paper reviews the recent anti-trust analysis of banking mergers as well as recent decisions by the Department of Justice and the Bundeskartellamt (in the last few months). We analyse the proposed merger between UBS and SBC in light of this evidence and focus on the domestic retail...

In a previous paper we have shown that the UBS-SBC merger would lead to an excessive concentration in the credit market for small and medium companies. The UBS has reacted to this paper in a series of letters to the Swiss competition authorities. We critically examine the content of these...

The welfare impact of a merger involves the market power offense and the efficiency defense. Salant et al. (1983) show that mergers among symmetric firms are unprofitable except for monopolization. We characterize the limit to this merger paradox in a simple linear Cournot oligopoly with...

This paper tends to examine the level of concentration of the banking sector in Bosnia and Herzegovina. The main objective of the paper is to measure the level of concentration and to investigate how the concentration and type of market structure affect the prices of banking products. By...

The DOJ and FTC clarify the role of labor market power ("monopsony") in the 2023 draft merger guidelines. The draft states in Guideline 11 that the structural presumption threshold applies to labor market concentration, while also suggesting that a stricter threshold may be warranted in labor...

An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level...

Worldwide, the overwhelming majority of large horizontal mergers are cleared by antitrust authorities unconditionally. The presumption seems to be that efficiencies from these mergers are sizeable. We calculate the compensating efficiencies that would prevent a merger from harming consumers for...
