Copyright and Creativity: Evidence from Italian Operas
This paper exploits variation in the adoption of copyright laws – due to idiosyncratic variation in the timing of Napoléon’s military victories – to investigate the causal effects of copyright laws on creativity. To measure variation creative output, we use new data on 2,598 operas that premiered across eight states within Italy between 1770 and 1900. This analysis indicates that the adoption of basic levels of copyright laws raised both the level and the quality of creative output in states with copyrights. The benefits of additional years of copyright, however, decline with the existing length of copyrights. Composer-level analyses indicate that much of the observed increase in creativity was driven by immigrants, who were attracted to states with favorable copyright terms. Consistent with agglomeration externalities, we also find that cities with a better pre-existing infrastructure of performance spaces benefitted more copyright laws.
