Upstream Innovation Protection: Common Law Evolution and the Dynamics of Wage Inequality

Abstract

What is the most innovation-enhancing level of patent protection for the new ideas generated within the framework of multi-stage sequential innovation? How does increasing early innovation appropriability affect basic research, applied research, education, and wage inequality? What does the common law system imply on the macroeconomic responses to institutional change? We show how the jurisprudential changes in intellectual property rights witnessed in the US after 1980 can be related to the well-known increase in wage inequality and in education attainments. A Schumpeterian general equilibrium approach is followed.Basic and Applied R&D, Sequential Innovation, Skill Premium, Inequality and Education, Research Exemption, Common Law
