Berkman Center

At the Berkman Center for Internet & Society at Harvard Law School you can read this paper about DRM "Why DRM Should Be Cause for Concern" by Paul Petrick:

In response to piracy and online file trading, the music industry has begun to adopt technological measures, often referred to as digital rights management (DRM), to control the sale and distribution of music over the Internet. Previous economic analysis on the impact of DRM implementation has been overly simplistic. A careful analysis of copyright law and the microeconomic principles governing the music industry demonstrates that commentators have failed to account for factors relevant to the measure of social welfare within the music industry. This paper develops a more refined economic model that is better suited to accurately assessing how legal or technological changes like DRM will affect the music industry.
