There's some evidence showing trends like that I think. Iron Maiden some years back looked at the places their music was most pirated and set up concerts in those areas, which IIRC then proceeded to sell tickets incredibly well.

There's that Gabe Newell quote, "Piracy isn't a cost issue, it's a service issue" or something like that. That's great discussion to be had on how copyright protections have prevented art of any kind from really gaming the impacts they can in the modern day, as well as interference driven by the profit motive or ingrained systems of abuse like sexual assault and crunch.
