The EU’s General Data Protection Regulation came into effect in 2018 to tackle issues of privacy and personal data. Looking at over 110,700 websites before and after the introduction of the regulation, this column examines its effect on non-EU-based websites and on other policy domains, such as competition or trade policy. Both EU-based and non-EU-based websites switched to more privacy-sensitive technologies following GDPR, but only in the short term. The market for web tracking technologies became more concentrated, with Google gaining the most market share among large providers. Privacy regulations can function as nonpecuniary barriers to trade, especially if enacted by a large economic area.

There is a developed public discourse on the need for more enforcement, regulation and legislation of digital platforms. Regulating ‘gatekeeper platforms’ has emerged as a major plank of the new European Commission mandate, with a consultation process underway this week for a plan to introduce both ex-ante regulation and a new market investigation tool with quasi-regulatory powers. This column asks how economists can contribute to rationally progressing the debate, so that it is not based on subjective priors, but uses applied theory to make testable predictions, and data to discriminate between theories.
