IPR protection and innovation, but the evidence is stronger for developed countries than for developing countries. Thirdly …, the optimal level of IPR protection should tradeoff the social benefits of enhanced innovation against the social costs of …

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current … debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form … of blocking patents. We show that patent protection changes the direction of innovation by having asymmetric effects on …

This study analyzes how patent protection affects innovation in an R&D-based growth model with elastic labor supply. We … find that increasing patent breadth may generate an inverted-U effect on innovation depending on whether the model features … the knowledge-driven or lab-equipment innovation process. This result highlights an important interaction between elastic …

This study develops an R&D-based growth model that features both vertical and horizontal innovation to shed some light … on the current debate on whether patent protection stimulates or stifles innovation. Specifically, we analyze the growth … ladder. We show that patent protection has asymmetric effects on vertical innovation (i.e., quality improvement) and …

We construct a tractable general equilibrium model of cumulative innovation and growth, in which new ideas strictly … the rate of innovation, as well as a separate optimal required inventive step that maximizes welfare, with the former …
