P&D, inovação e produtividade na indústria: uma abordagem para o Brasil

Abstract

The following literature suggests that R&D and human capital measures are the main inputs for innovation. Furthermore, it is well established that innovation is fundamental for productivity and development. This study, from a structural model in line with the CDM model, analyzes the impact of innovative activities on the productivity of Brazilian industrial firms connecting innovation input, innovation output and firms' economic performance. This paper aims to evaluate two parallel measures of innovative input, internal R&D expenditure and workers classified as PoTec. For this purpose, mainly data from the Pesquisa de Inovação (PINTEC) will be used, which were released by the IBGE, and in regards to workers, RAIS data, provided by the MTE, in order to create panel data. From an econometric perspective, one can submit this database to Chamberlain's random effects probit model to estimate the decision to invest in research and innovation production function. For the R&D expenditure equation, one uses an estimator proposed by Wooldridge (1995) for selection bias correction, and finally, uses a fixed effects model for the estimation of the firm's production function. To provide consistent estimates, the importance of controlling unobserved effects and considering an alternative measure to R&D expenditure is noted. For Brazil, it can be observed that the intensity of PoTec workers positively affects the probability of innovation in the market and highlights the importance of innovation for increased productivity of the domestic industry. The results point to the importance of controlling unobserved effects and using alternative measures to R&D expenditure in order to provide consistent estimates. For Brazil, it can be observed that the extent PoTec workers positively affects the probability of leading to innovation in the market and it is important to highlight that innovation increases domestic industry productivity.
