Knowledge drives the growth of nations and regions in a competitive space-economy. Hence, we would expect a strong correlation between investments in R&D, knowledge and learning processes, on the one hand, and productivity increases, on the other. However, the empirical evidence shows consistent...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer (1990). In the first part, we present different versions of the benchmark linear model with imperfect competition. These include the “labequipment” model, labor-for-intermediates” and...

In this paper, we aim at re-assessing the undisputed positive relationship between innovation and economic growth by questioning the view that R&D (and formal knowledge in general) equates innovation and innovation equates regional growth. We rather propose that these linkages are strongly...
