Abstract
Previous empirical results on the determinants of R&D intensity have indirectly suggested the relevance of unobserved R&D-related capabilities. Cohen and Klepper (1992) have developed a probabilistic model that is able to conform with well known stylized facts on the R&D intensity distribution such as clustering around zero, unimodality and positive skewness and generates well defined predictions about the correlation between the different distribution moments (mean, variance, coefficient of variation and skewness). The evidence for 3-digits sectors of the manufacturing industry in São Paulo is to a great extent consistent with the referred theoretical model.References
