How do copyright laws affect creativity? Do stronger laws increase profitability -- and, therefore, do they increase creativity? If musicians/filmmakers/authors/software designers/etc. etc. etc. don't have the strong incentive of copyright protection, will they create less or inferior work?
These question are both broad and long; many great minds have wrestled with them, and will continue to do so. Our recurring guest bloggers Kal Raustiala and Chris Sprigman regularly discuss copyright; Levitt touched on it here, and we discussed copyright protection in this podcast.
Now, in a new working paper (abstract; PDF) called "Copyright and the Profitability of Authorship: Evidence from Payments to Writers in the Romantic Period," Megan MacGarvie and Petra Moser take up the argument:
Scott Turow, President of the American Authors’ Guild, warned that regimes that weaken copyright, such as digital piracy may cause the “slow death of the American author” (Turow 2013). Empirical analyses of file sharing, however, reveal no significant effects on the quantity or quality of recorded music (Oberholzer-Gee and Strumpf 2009; Waldfogel 2013), which suggests that the importance of copyright protection may be overstated.
