Law and Innovation in Copyright Industries

Abstract

The impact of copyright law on innovation is a topic of much debate. We use quarterly data on aggregate copyright applications in both the U.S. and Canada to estimate an empirical model of copyright applications. We measure changes in the breadth of copyright protection by tabulating outcomes of important court cases and new statutes pertaining to copyright protection. We find that the flow of applications exhibits a small but significant positive response to court decisions broadening copyright protection. We also find that applications: 1) respond negatively to increases in registration fees 2) move counter-cyclically 3) have a strong seasonal component and 4) may increase as computing technology becomes more widely available.
