Modélisation non-linéaire de l'impact des TIC sur la productivité du travail

This paper focuses on dynamic of diffusion of Information and Communications Technology (ICT) and their impact on labor productivity. Our contribution lies in taking into account the non-linearity of this relationship arguing successively integration time and a time when new productivity gains appear. The existence of this particular sequence is modeled using a Logistic Smooth Transition model (LSTR) which permits to verify the delayed effect assumed for nine of the twelve countries studied. Different values of the adjustment periods across them are related to the structural characteristics of economies considered.
