The conclusion seems right to me – file-sharing increases social-welfare, so in theory a win-win solution is possible, but in practice the increase comes at the expense of music firms.

That reminded me of Zimran (“winterspeak”) Ahmed’s back-of-the-envelope estimate that the music copyright tax causes a deadweight loss of $3 billion per year.

Longtime readers may remember that I mentioned Zimran’s analysis here, and I probably did in earlier posts as well, but they are not as well archived (I was doing my own archiving when I first started blogging).
