Jean-Michel ETIENNE a présenté un article à la “8th Conference on Micro Evidence on Innovation and Development (MEIDE)” co-organisée par l’OCDE et la Banque Mondiale, les 10, 11 et 12 Février 2015 à New Delhi (Inde). Ce papier s’intitule “Inclusive growth and innovation: a dynamic simultaneous equations model on a panel of countries” (co-écrit avec Georges Bresson et Pierre Mohnen).
Based on the work of Anand et al. (2013) we measure inclusive income growth, which combines growth in GDP per capita and growth in the equity of the income distribution.
Extending the work of Causa et al. (2014), we estimate a dynamic simultaneous structural equations model of GDP per capita and inclusive income on panel data for 63 countries over the 1990-2013 period. We estimate both equations in error correction form by difference GMM. Among the explanatory variables of the level and the distribution of GDP per capita we include R&D expenditure per capita. In OECD countries we obtain a large positive effect of R&D on GDP. R&D is found to have a positive effect on the social mobility index but its impact on the income equity index at first decreases, then switches around to become slightly positive in the long run. In non-OECD countries R&D is found to decrease inclusive income, mostly through a negative growth effect but also because of a slightly increasing income inequity effect.
