Our paper identifies and estimates the effects of R&D spillovers on total factor productivity with consideration of spatial effects. We first run our estimations on the Coe and Helpman (1995) model introducing spatial correlation. The results show positive R&D spillover effects on TFP and high...

The aim of this paper is to identify the determinants of Research and development (R&D) investment in French firms. For analysis of covariate effects on R&D expenditures, a two-part model that combines a probit regression on the decision to perform R&D and a linear regression on log-positive...

We explore the impact of spatial and technological R&D spillovers on the innovative activities in Europe. We consider a linear feedback model to explain the dynamics of count data processes relative to patents and R&D expenditures. Estimations are made on a panel data set relative to public and...
