Abstract

This paper analyzes how patent protection affects economic growth in a continuous-time overlapping generations model with lab-equipment type R&D-based growth. We show that increasing patent breadth may generate an inverted-U effect of patents on economic growth, an effect which is partly consistent with an empirically observed nonmonotonic relationship between patent protection and economic growth. This paper also shows that the combinations of heterogeneous households with finite lifetimes and the lab-equipment type R&D specification are relevant for deriving the inverted-U effect of patent protection on economic growth.
