"What the Commission found out about copyright infringement but ‘forgot’ to tell us"
"Does copyright infringement negatively affect legal sales? This is a fundamental question with profound implications on the way copyright and copyright enforcement policy should work.
In January 2014, the European Commission awarded the Dutch company Ecorys a contract worth €360.000 to conduct a study on the question."
"The study’s conclusion: With the exception of recently released blockbusters, there is no evidence to support the idea that online copyright infringement displaces sales. While this result is not unique, but consistent with previous studies, it begs the question:
Why did the Commission, after having spent a significant amount of money on it, choose not to publish this study for almost two years?"
