Optimal Copyright Over Time: Technological Change and the Stock of Works
14 Pages Posted: 13 Jun 2008
The optimal level for copyright has been a matter for extensive debate over the last decade. Using a parsimonious theoretical model this paper contributes several new results of relevance to this debate. In particular we demonstrate that (a) optimal copyright is likely to fall as the production costs of 'originals' decline (for example as a result of digitization) (b) technological change which reduces costs of production may imply an increase or a decrease in optimal levels of protection (this contrasts with a large number of commentators, particularly in the copyright industries, who have argued that such change necessitates increases in protection) (c) the optimal level of copyright will, in general, fall over time as the stock of work increases.
