Intellectual property rights as development determinants

While intellectual property rights (IPRs) are the key drivers of economic performance in R&D based growth models, they have not been fully explored in empirical development studies. We introduce IPRs to this literature, using Two-Stage Least Squares Bayesian Model Averaging to address endogeneity and model uncertainty at the instrument and income stages. We show that IPRs exert effects similar to 'Rule of Law' and therefore provide robust evidence that both physical and intellectual property rights are crucial development determinants. We document that unenforced IPRs exert no effect on development. Instead, it is the level of enforced IPRs that causes development. JEL classification: O1, C1
