Have European regulations dampened euro-zone growth?

The Brexiters’ main argument against UK membership in the European Union is that the various European regulations slow down European countries ’ growth ; this argument is regularly held up by Donald Trump and by the eurosceptics. Can we see signs that regulations (climate and environmental, social, fiscal, industrial, food safety, etc.) have dampened euro-zone growth compared with growth in the United States? We show that it is very difficult to defend this theory: the euro zone is taking the lead in energy transition, has a higher employment rate than the United States, has used fiscal policy very intensely (except Germany's and the Netherlands), and has lost fewer manufacturing jobs than the United States.
