Copyright is based on a social contract. In return for a government-enforced, time-limited monopoly, artists create - the idea being that without that monopoly, it would not be worth their while to produce works because copies could be made that would undermine their value and hence the artists' livelihood.
Of course, this flies in the face of the fact that Shakespeare, Rembrandt, Bach and all the rest enjoyed no copyright in their works, and yet, demonstrably, produced rather a lot of rather good stuff.
Ah, yes, but, the content industry will retort: things are different now, etc. etc. The trouble is, we have no way of testing whether things really are different now - in other words, whether, in the absence of copyright, people would carry on creating.
Well, actually we do, because the almost universal sharing of music and other content is effectively creating a copyright-free world for digital artefacts. For recorded music, which is now overwhelmingly digital, that means what is more or less a copyright-free world. And so, following the logic of the industry, music creativity should be falling through the floor as musicians everywhere throw up their hands in despair, crying: "oh, where is my old quid pro quo?"
Given this interesting situation, it would of course be fascinating to know whether that is the case or not. That's a non-trivial piece of research for a number of reasons, but Joel Waldfogel at The Carlson School and Department of Economics, University of Minnesota has made a valiant effort to deal with the problems, and published his results [.pdf]:
In the decade since Napster, most observers have concluded that file-sharing undermines the protection that copyright affords recorded music. What matters for consumers, however, is not sellers’ revenue but whether the diminished appropriability will reduce the availability of new recorded works. The legal monopoly created by copyright is justified by its encouragement of the creation of new works, but there is little evidence on this relationship. The file-sharing era can be viewed as a large-scale experiment allowing us to check whether diminished appropriability stems the supply of new works. Using a novel dataset on the supply of new recorded music derived from retrospective critical assessments of music such best-of-the-decade lists, we compare post-Napster album supply to 1) its pre-Napster level, 2) pre-Napster trends, and 3) a possible control, new song supply following the iTunes Music Store’s revitalization of the single. We find no evidence that recent changes in appropriability have affected the quantity of new, acclaimed recorded music or new artists coming to market. We reconcile a stable flow of new works in the face of decreased demand with evidence on reduced costs of bringing works to market and a growing role of independent labels.
Looks like the social contract can now be torn up: even without that copyright monopoly - and remember, monopolies are bad things - artists are still creating.
Now, one study is hardly definitive proof, but it's suggestive to say the least. In particular, taken together with all the other evidence that sharing really doesn't hurt the music industry overall, it provides another shiny nail for the copryight maximalists' coffin. (Via Michael Geist.)
