Empirical Implications of Sequential Innovation and Legal Action
This article compares two hypotheses, sequential innovation and legal action, and theoretically obtains the testable implications to specify which hypothesis is crucial in empirical evidence. Our main results are that we distinguish between the two hypotheses based on i) whether the cross-term coefficient of the number of patents and the dummy of patent law are positive or negative and ii) whether the variance of the patent distribution is decreased.
