March 2020Copyright and Creativity. Evidence from Italian Opera During the Napoleonic Age
with Petra Moser: w26885
This paper exploits exogenous variation in the adoption of copyrights – as a result of the timing of Napoléon’s military victories in Italy – to examine the effects of copyrights on creativity. To measure changes in creative output we compare changes in the creation of new operas across states with and without copyrights. Difference-in-differences analyses show that basic copyrights increased both the number and the quality of operas, measured by their popularity and durability. Notably, there is no evidence of comparable benefits for extensions in copyright lengths. Complementary analyses for other types of musical compositions confirm the main results.
June 2019Scientific Education and Innovation: From Technical Diplomas to University STEM Degrees
with Nicola Bianchi: w25928
This paper studies the effects of university STEM education on innovation and labor market outcomes by exploiting a change in enrollment requirements in Italian STEM majors. University-level scientific education had two direct effects on the development of patents by students who had acquired a STEM degree. First, the policy changed the direction of their innovation. Second, it allowed these individuals to reach top positions within firms and be more involved in the innovation process. STEM degrees, however, also changed occupational sorting. Some higher-achieving individuals used STEM degrees to enter jobs that required university-level education, but did not focus on patenting.
January 2019Does Scientific Progress Affect Culture? A Digital Text Analysis
with Nicola Lacetera, Astrid Marinoni: w25429
We focus on a unique episode in the history of science, the elaboration of the theory of evolution by Charles Darwin, to study the interplay between scientific progress and cultural change. We perform text analysis on a corpus of hundreds of thousands of books, with the use of techniques from machine learning. We examine, in particular, the diffusion of certain key ideas of the theory of evolution in the broader cultural discourse and imaginary. We find that some concepts in Darwin’s theory, such as Evolution, Survival, Natural Selection and Competition, diffused in the cultural discourse immediately after the publication of On the Origins of Species. Other concepts such as Selection and Adaptation were already present in the cultural dialogue. Moreover, we document semantic changes for mo...
