Patents and quality growth in OLG economy

  • Sorek, Gilad

Abstract

This paper shows how heterogeneity in patent ownership across generations and lifecycle saving considerations qualitatively change the conventional implications of patent policy for quality growth. We study a close Overlapping Generations economy that grows through sequential quality improvements (“quality-ladder”), to show that for plausible values of the Inter-temporal Elasticity of Substitution (a) shorter patent length enhances growth (b) under exogenous innovation size loosening patent breadth protection spurs R&D investment and quality growth and (c) the effect of loosening lagging breadth protection on R&D investment and quality growth under endogenous innovation size depends on patents length. Our findings explore a new channel through which strong patents may hinder innovation and emphasize the importance of coordination in patent-policy across the different dimensions of the patents system.
