Resumen

This paper constructs a dynamic model to estimate the impact of adjustment costs on the productivity of investment in R&D. In order to take into account the possible endogeneity of adjustment costs, the model is estimated by means of Instrumental Variables (IV), using a panel of Spanish companies. The results show that the elasticity of the productivity of R&D investment with regard to adjustment costs is high, with a value close to 1 (-0.96). This confirms that it is essential to include adjustment costs in the empirical analysis of R&D productivity, as suggested by Jones and Williams (1998) and Comin (2003, 2004).
