Our review of existing econometric studies suggests that P2P file-sharing tends to decrease music purchasing. However, we find the opposite, namely that P2P file-sharing tends to increase rather than decrease music purchasing. Among Canadians who engage in P2P file-sharing, our results suggest that for every 12 P2P downloaded songs, music purchases increase by 0.44 CDs. That is, downloading the equivalent of approximately one CD increases purchasing by about half of a CD.
