Evidencias del impacto de las TIC en la productividad de la empresa. ¿Fin de la «paradoja de la productividad»?

This paper offers a review and an analysis of the available empirical evidence regarding the relationship between ICT and productivity at the firm level. Our aim is to answer the question to what extent and under what sort of conditions, the paradox at the firm level has been refuted. From the theoretical framework of the production function, the literature is classified around various propositions. Results, methodological approaches, techniques and samples are reviewed and compared. Despite the existence of many biases as well as measurement problems and conditioning factors, we conclude that the productivity paradox at microeconomic level seems to be refuted.
