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...

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...

In this paper we present a model in which endogenous growth arises in competitive markets. Knowledge is described as a labor-augmenting factor used directly in the final goods' production. Firms demand both basic nonrival knowledge contents, which are supplied jointly and inelastically with raw...
