The economic importance of innovation brings with it an active debate on the impact public policy has on the innovation process. This annual series, sponsored by the National Bureau of Economic Research, brings the work of leading economic researchers to the broader policy community. Issues covered in Volume 11 include an exploration of innovation challenges in the health care and cleantech industries and the implications for public policy; a reconsideration of static antitrust analysis on innovation incentives, an examination of innovations in governance that encourage investment and growth, and the impact of the dynamic nature of scientific research and technological innovation on science policy.
