Abstract
According to the available evidence, stronger patent protection exerts, at best, a modest positive effect on economic growth. Different variants of Schumpeterian growth models predict a wide range of outcomes, from strongly positive to strongly negative effects. We propose a Schumpeterian growth model with endogenous innovation scale, a generalized innovation function that combines R&D lab-equipment and labor-embodied technical knowledge, and a complexity-of-innovation effect. Consistent with the evidence, plausible calibrations of the model suggest that a typical OECD economy lies near the peak of an inverted-U-shaped curve, where the effect of stronger patent protection on growth is close to zero. In some cases, this effect may even be negative.
