Why has physical piracy of music grown globally in recent years despite international efforts to reduce the problem? This research employs cross-country time series data analysis to examine physical music piracy rates across developed and developing economies. We provide 1999-2004 cross-country evidence from 70 countries that mean global music piracy rates grew over this period, and observe different mean rates for OECD and non-OECD countries. We examine the effect of per capita income, legal enforcement and technology on piracy rates in the developed and developing economies and choose a fixed-effects model. Our model indicates that variations in piracy of CDs and digital music on CD-Rs among all countries are largely due to growing Internet subscriptions. For non-OECD countries, the model suggests that the increase in Internet use coupled with poor copyrights enforcement has worsened piracy. For OECD countries, however, the growth in Internet subscriptions has not had a significant effect on piracy rates.
