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 a decrease 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.
The optimal term of copyright has been a matter for extensive debate over the last decade. Based on a novel approach we derive an explicit formula which characterises the optimal term as a function of a few key and, most importantly, empirically-estimable parameters. Using existing data on recordings and books we obtain a point estimate of around 15 years for optimal copyright term with a 99% confidence interval extending up to 38 years. This is substantially shorter than any current copyright term and implies that existing terms are too long.
