Brief 60: Sainsbury’s/Asda and the CMA’s GUPPI decision rule: On the money or basket case? 16.10.19
In April 2019, the UK’s Competition and Markets Authority (CMA) issued one of its highest-profile decisions in recent years, prohibiting the proposed merger between the supermarket chains Sainsbury’s and Asda.1 In so doing, it relied solely on Gross Upward Pricing Pressure Index (GUPPI) calculations to determine if local overlaps in the parties’ grocery stores were likely to result in a substantial lessening of competition (SLC).
This Brief considers the wider implications of the CMA’s mechanical use of GUPPI values as a decision rule in this case.

Brief 59: A questions of balance: comments on a proposed new test for UK merger control 01.05.19
Digital markets are under intense scrutiny. A notable concern is that competition authorities have insufficient scope to block acquisitions of innovative potential entrants that might otherwise have become a disruptive competitive influence and a spur for increased innovation in digital markets. In one response, a recent report prepared for the UK Government by a digital competition expert panel headed by Professor Jason Furman has proposed significant reforms to the UK merger regime. These include a recommendation that the “balance of probabilities” test of harm currently applied by the UK Competition and Markets Authority (“CMA”) is replaced by a new test based on the “balance of harms”. Similar issues are also considered in a recent report commissioned by DG Competition: “Competition Policy for the Digital Era” by Jacques Crémer, Yves-Alexandre de Montjoye and Heike Schweitzer.
This latest RBB Brief discusses the merits of introducing a balance of harms test into merger control.
