Big Tech mergers increasingly require regulatory authorities with enhanced toolboxes. To ensure genuine competition in the digital marketplace, novel theories of harm will need to be elaborated and applied. This column provides guidance on these issues, arguing that to properly investigate Big Tech mergers, competition law will need to restructure the standards and burden of proof.


The Barcelona Graduate School of Economics is holding an intensive course on the Competitive Effects of Mergers from November 7-9, 2018.
This three-day course will provide participants with a thorough understanding of the crucial role of competition enforcement in merger control by looking at established and new economic theories on mergers, the relevant empirical methods, as well as providing insightful discussions on recent high-profile merger cases in Europe and the US harm. The course will be taught by leading academic and professional economists:
Massimo Motta (ICREA-UPF and Barcelona GSE; former Chief Competition Economist, European Commission), course director; Giulio Federico (European Commission); Natalia Fabra (Universidad Carlos III de Madrid); Aviv Nevo (University of Pennsylvania; former Chief Economist, Antitrust Division, U.S. Department of Justice); Elena Zoido (CompassLexecon).

Recent empirical work finds a strong negative correlation between competitive markets and gender wage gaps, in particular when competitive markets are measured by the components “free trade”, “absence of regulation” and “legal structure”.

Anti-competitive behaviour raises prices and private enforcement action allows ‘victims’ to recover some of the losses. Calculating the losses is not straightforward since the victims may pass-on some of the higher prices for inputs to their customers who then become indirect victims. The EU should allow adjustment for this passing-on and give legal standing to those indirectly affected.
