This manuscript contributes to the literature on firm cooperation with universities and Knowledge Intensive Business Services (KIBS) by framing the analysis according to the literature on causal effects, comparing the effect of each of the agents and exploring which firms benefit the most from cooperation with a specific partner. The results have shown that the bias-adjusted effect is around a 27-30% increase in sales from new products for both types of partners. After covariates and fixed effects are used, it is considered unlikely that this effect is driven by time-varying unobservable factors. Moreover, we have seen that firms that benefit the most from cooperation with universities are different from those firms that benefit the most from cooperation with KIBS.
Este manuscrito contribúe á literatura sobre a cooperación de empresas con universidades e Knowledge Intensive Business Services (KIBS) enmarcando a análise segundo a literatura sobre efectos causais, comparando o efecto de cada un dos axentes e explorando qué empresas se benefician máis da cooperación cun socio específico. Os resultados mostraron que o efecto axustado polo sesgo provoca ao redor dun 27-30% de aumento das vendas de novos produtos para ambos os tipos de socios. Unha vez utilizadas as covariables e os efectos fixos, considérase pouco probable que este efecto sexa debido a factores inobservables que varían co tempo. Ademais, temos mostrado que as empresas que máis se benefician da cooperación coas universidades son diferentes das que máis se benefician da cooperación cos KIBS.
