Beyond the theoretical and historical arguments about the effects of enclosure on real property lie the question of how well those arguments translate to the world of the intangible and intellectual. It is that question which this chapter raises. Christopher May, A Global Political Economy of Intellectual Property Rights: The New Enclosures? (London: Routledge, 2000) offers a similar analogy—as do several other articles cited in the text. The key differences obviously lie in the features of intellectual property identified in the earlier chapters—its nonrivalrousness and nonexcludability—and on the ways in which a commons of cultural, scientific, and technical information has been central to the operation of both liberal democracy and capitalist economy. I owe the latter point particularly to Richard Nelson, whose work on the economics of innovation amply repays further study: Richard Nelson, Technology, Institutions, and Economic Growth (Cambridge, Mass.: Harvard University Press, 2005)."
