Note (General): * Revised: [05-23, 2005]
This paper examines the growth effects of intellectual property right (IPR)protection in a quality-ladder model of endogenous growth. Stronger IPRprotection, which reduces the imitation probability, increases the reward forinnovation. However, stronger protection also gradually reduces the number ofcompetitive sectors, in which innovation is easier than in monopolistic sectors.With free entry to R&D, the number of researchers in each remaining competitivesector increases, but the concentration of R&D activity raises the possibilityof unnecessary duplication of innovation, thereby hindering growth. Consequently,imperfect rather than perfect protection maximizes growth. Welfareand scale effects are also examined.
