Optimal patent policy, research joint ventures, and growth

Abstract

The patent-and-growth studies have found that there may be welfare loss without optimizing both patent breadth and the division of profit in competitive research joint ventures (NJs). This paper examines the effects of patent policy on an R&D-based growth model where innovations are produced by cooperative research joint ventures (CJs). We show that CJs always generate a higher equilibrium growth rate than NJs, and the social optimum can be achieved with CJs in equilibrium when only patent breadth is chosen optimally.
