I’ve been commenting on the weakness of the DOJ complaint and in particular, its heavy reliance on market structure to make inferences about competitive effects. The heavy dose of structural presumption in the DOJ complaint — especially in light of the DOJ / FTC’s new Horizontal Merger Guidelines which stress reducing that emphasis because it is grounded in outdated economic thinking in favor of analysis of actual competitive effects — reads more like a 1960s complaint than a modern post-2010 Guidelines approach.
