Competition and Innovation: the effects of scientist mobility and stronger patent rights

Abstract
We analyze the relationship between innovation attributes and competition intensity in a framework of endogenous knowledge spillover due to scientist mobility, and identify the effects of stronger patents on innovation at different levels of product market competition. We �nd non-monotone relations of patenting propensity, innovation incentives and investment in R&D, and monotone relation of scientist mobility, with potential product market competition intensity. The study further shows that stronger patent laws reduce (increase) innovation profitability (R&D expenditure) when the market for the new product is moderately competitive, and have no effect otherwise. The results suggest important implications for patent policy reforms.
