Intellectual Property Rights and Crop-Improving R&D under Adaptive Destruction
AbstractThis paper studies how the strength of intellectual property rights (IPRs) affects investments in biological innovations when the value of an innovation is stochastically reduced to zero because of the evolution of pest resistance. We frame the problem as a research and development (R&D) investment game in a duopoly model of sequential innovation. We characterize the incentives to invest in R&D under two competing IPR regimes, which differ in their treatment of the follow-on innovations that become necessary because of pest adaptation. Depending on the magnitude of the R&D cost, ex ante firms might prefer an intellectual property regime with or without a Ã¯Â¾âresearch exemptionÃ¯Â¾â provision. The study of the welfare function that also accounts for benefit spillovers to consumersÃ¯Â¾âwhich is possible analytically under some parametric conditions, and numerically otherwiseÃ¯Â¾âshows that the ranking of the two IPR regimes depends critically on the extent of the R&D cost.
