This paper studies the impact of the shift in the U.S. patent system towards the patentability and commercialization of the basic R&D undertaken by universities during the early 1980s. We interpret this change as rendering universities responsive to "market" forces. Prior to 1980, universities undertook research using an exogenous stock of researchers motivated by "curiosity." After 1980, universities patent their research and behave as private firms. This move, in a context of two-stage inventions (basic and applied research) has an a priori ambiguous effect on innovation and welfare. We build a Schumpeterian model and match it to the data to assess this important turning point from an innovation as well from a welfare-enhancing perspective.enInnovation PolicyInstitutionsPublic Basic ResearchQuality LadderUntargetable Basic Researchworking paper
