The Andersen P2P file sharing study on the purchase of music CDs in Canada

In 2006, the highly regarded economics professor Prof. Liebowitz, Director of the Center for Economic Analysis of Property Rights and Innovation at University of Texas, surveyed the entire field of econometric studies on file sharing. On the basis of his comprehensive review (which displayed a remarkable consensus on the issue), he concluded that “file-sharing has brought significant harm to the recording industry”. Prior to that in a comprehensive article published in 2005 Prof. Liebowitz criticized the theory that unlicensed file sharing helps copyright owners.
