overcoming these collective action problems. Without the data, empirical researchers will be frustrated in their efforts to illuminate the copyright system. On the other hand, making data available will enable the community of academic and industry investigators to propose, design, and carry out policy-relevant studies well beyond those we discuss in this report.
Drawing on work commissioned by the committee, the next part of this report presents the case for developing a broad empirically-based research agenda on copyright law and policy. It begins with an overview of the logic and evolution of copyright and then surveys the importance of copyright-impacted industries and copyrighted works to the nation’s economy and how they have been affected by digital technology. It concludes by briefly reviewing how the existing literature reveals the limits of our knowledge about the efficacy and intended and unintended effects of copyright protection.
