The Digital Markets Act Is More Intricate Than Regulators and Detractors Give It Credit For

The European Union’s Digital Markets Act (DMA), designed to regulate Big Tech, supplements current antitrust laws that pursue case-by-case analyses of business conduct with general rules to block potentially anticompetitive behaviors. Detractors criticize the DMA for its lack of nuance. Supporters applaud its general principles as a necessary bulwark against Big Tech’s market powers, which current case-by-case analysis has been unable to rein in.

Antitrust Regulation of Big Tech Needs a Better Understanding of Behavioral Economics

Recent antitrust interventions have put forward behaviorally informed theories of harm. However, they have adopted a deterministic model of behavior, missing the nuances that allow behavioral economics to provide a richer picture of people’s conduct. The recently concluded Google trial, grounded on the stickiness of defaults, is a good example. A more careful application of behavioral economics would have shown how Google’s purchase of default search engine status was a part of a broader monopolization plan. It would also show why the dominant remedy, forced choice, would have negligible effects.
