This paper analyzes the determinants of labor productivity in the services firms of Colombia. In particular, we examine the relation between information and communication technologies –ICT– (in terms of investment and use) and productivity. The study finds that ICT investment and use jointly increase labor productivity in about 18% on average. The empirical evidence supports the hypothesis that ICT technological resources (both in equipment investment and ICT use), together with non-ICT capital, training, and the proportion of foreign capital and permanent workers are the main determinants of productivity increase in the Colombian services firms
