Is Data “The New Oil”? Non-Price Effects of Mergers in Data-Intensive Industries

In recent years, regulators and other interested parties have advocated for increased attention to non-price effects of mergers, particularly when data is a key input but not the main product of the merging parties. In these mergers, economic analysis has sometimes shown that the resulting combined datasets may have an adverse impact on competition or consumer welfare. In “Is Data ‘The New Oil’? Non-Price Effects of Mergers in Data-Intensive Industries,” an article published in CPI Antitrust Chronicle, three Analysis Group consultants analyze these non-price effects and their potential consequences for competition.

In the article, Managing Principals Emily Cotton and Rebecca Kirk Fair and Vice President Philipp Tillmann examine three topics that antitrust authorities and industry observers have raised as particularly concerning with respect to anticompetitive effects: potential entrenchment, data privacy, and potential foreclosure from data inputs. The authors discuss both the potential effects of these topics and remind readers that investigations into their impacts should consider not only anticompetitive aspects but the potential gains in quality, data security and privacy, and production efficiencies from such mergers.

German antitrust community debates how to most effectively consider economic expert reports in follow-on cartel damage proceedings

Compared to other jurisdictions, such as the US, economic expert reports have only relatively recently become commonplace in determining follow-on damages in German cartel proceedings. In his article in the Global Private Litigation Committee’s December 2023 newsletter, published by the American Bar Association Antitrust Law Section, Analysis Group Vice President Philipp Tillmann summarizes changes being debated in the German antitrust community over how German courts could make more effective use of such expert reports.

Dr. Tillmann discusses concerns related to the cost and organization of proceedings, objective standards for expert reports, and how to manage experts’ divergent conclusions. He also outlines several proposed solutions, including relying on court-appointed economists, adopting common standards for experts and their reports, bundling small claims to allow for true class actions, and utilizing specialized courts to handle antitrust matters.

The Economics of Pass-Through With Production Constraints

Analysis Group Vice President Dov Rothman and Managers David Toniatti and Philipp Tillmann have published an article in the Journal of Competition Law & Economics examining the implications of production constraints for the pass-through of cost changes.

In “The Economics of Pass-Through With Production Constraints,” the authors consider production technology that can only be adjusted in discrete intervals and/or is costly to adjust.

They demonstrate that, because of such production constraints, a firm may not pass on small changes in costs to its customers.

The authors suggest that this result has important implications for antitrust litigation – for example, the extent to which overcharges resulting from anticompetitive conduct upstream in the supply chain are passed through to purchasers downstream.
