There’s this @ecipe study (funded by Google) making the rounds, alleging that the European Commission's DSA will cost 2 million jobs and €85 billion per year in lost GDP! That’s a lot.

So I looked into it.

1/

Dubious methodologies and identification, but let’s ignore them. The core of the study is this: they have a bunch of country-sector EU data from 2010 to 2017. They estimate some TFP and see how TFP is affected by an “ex ante regulation” dummy that covers the period 2015-2017.

2/

What happened 2015? Explanation buried in footnote 3: “Regulation 2015/2020 shifts the general antitrust regulatory approach from ex post to a universal ex ante obligation in the EU telecom sector.”

I’ve studied telecoms my whole professional life and I can tell you: *nothing* changed in EU telecoms regulation in 2015 that brought regulation from ex post to ex ante.

This study is just ridiculous. Can journalists please avoid even mentioning it? Much appreciated.
