Inovação endógena e crescimento regional: estimando a função de produção de idéias para as regiões brasileiras

Abstract

Estimating the production function of ideas to provide a better empirical comprehension of the income differential among brazilian regions is the main focus of this paper. By taking endogenous growth models framework, recent theoretical debates have relied on neoschumpeterians models where technological innovation has provided with strong evidenced toward positive externalities on growth. This is the theoretical reason which this paper is relied on. Econometric models provide the measuring of spillovers of ideas, not only over time but also across regions, in the process of generating externalities. The results allow inferring two distinct conclusions. Firstly, there is evidence of a strong feedback in the R&D toward spillover over time with increasing returns in production. Secondly, it is verified a significant regionally negative spillover effect, which indicates that the production of ideas is competitive among regions, therefore, there must have comparative advantage in the regional income distribution.
