While I am absolutely open to the possibility that the GDPR has negative effects on technology venture investment (as their paper suggests), I am a bit disappointed that they did not attempt to correct for the effects of the UK leaving the EU. At the very least it would have been nice if, in addition to graphs for the entire EU, there were graphs for the UK alone, and also for the EU without the UK. That way it might have been possible to get a vague impression of how much these numbers are affected by Brexit instead of the GDPR.
