Description
  • Abstract

    Copyrights, which establish intellectual property in music, science, and other creative goods, are intended to encourage creativity. Yet, copyrights also raise the cost of accessing existing work - potentially discouraging future innovation. This paper uses an exogenous shift towards weak copyrights (and low access costs) during WWII to examine the potentially adverse effects of copyrights on science. Using two alternative identification strategies, we show that weaker copyrights encouraged the creation of follow-on science, measured by citations. This change is driven by a reduction in access costs, allowing scientists at less affluent institutions to use existing knowledge in new follow-on research.

Geographic Coverage
  • United States, Germany
Sampled Universe
Our main data include BRP books in chemistry and mathematics, a control group of Swiss books in the same fields, and all new articles and books that cite BRP and Swiss books between 1920 and 1970. Two alternative measures for scientific output capture new PhD theses in mathematics and US patents that use knowledge in BRP books.
