Curiosidade do dia

"the natural experiment, where the recorded music industry removes DRM on music at diff erent times, provides the fi rst evidence on the eff ect of a more "relaxed" digital copyright strategy on sales and, in particular, on the entire sales distribution.
My analysis in this paper, based on a large representative sample of albums from all four major record companies, sheds light on this question. I finnd that the removal of DRM increases digital sales by 10%. More importantly, the e ffect is most pronounced for albums at the long tail of the music sales distribution, providing support for the long tail hypothesis that lowering search costs can facilitate product discovery of non-mainstream fare."
