Abstract
This paper investigates the effects of illegal file sharing (piracy) on music and movie sales. The Swedish implementation of the European Union directive IPRED on April 1, 2009 suddenly increased the risk of being caught and prosecuted for file sharing. We investigate the subsequent drop in piracy as approximated by the drop in Swedish Internet traffic and the effects on music and movie sales in Sweden. We find that the reform decreased Internet traffic by 18 percent during the subsequent six months. It also increased sales of physical music by 27 percent and digital music by 48 percent. Furthermore, it had no significant effects on the sales of theater tickets or DVD movies. The results indicate that pirated music is a strong substitute for legal music whereas the substitutability is less for movies.
Main Results of the Study
This article empirically investigates the effects of copyright protection reform on Internet piracy and on sales of music and movies. More specifically, This article argues that:
- The Swedish implementation of the IPRED law on April 1, 2009 suddenly increased the risks of piracy. Piracy decreased and that music sales increased after the law reform.
- Pirated music is a strong substitute to legal music, whereas the substitutability is less for movies. After six months, piracy recovered to a large extent, which resulted in a decrease in the demand for legal music and decreased physical as well as total sales.
- This raises some doubts regarding the effectiveness of such law reforms in the long run, but it also points towards better legal alternatives to piracy as a possible way forward for the music industry.
Policy Implications as Stated By Author
- Law reform can be effective in preventing piracy and in increasing music sales for the first six months. Some of these effects must be attributed to a combination of the law and widespread public interest. - It is possible that convictions would restore an effect that is more long-lasting.
