The knowledge production function is central to R&D-based growth models. This paper empirically investigates the knowledge production function and intertemporal spillover effects using cointegration techniques. Time-series evidence suggests there are two long-run cointegrating relationships. The...

This paper re-examines the Romer [1990] "knowledge driven" endogenous growth model in an open economy setting. As an alternative to Rivera-Batiz and Romer [1991], we consider trade between two absolutely identical countries that are characterized by imperfect competition in one of the trade...

The legal monopoly granted by the patent system has often been criticized for its inefficiency, which is exacerbated by the peculiarities of knowledge as a public good. In this paper we aim at studying more deeply the latter concern. Hence we build a model in which monopolistic exploitation does...

The knowledge production function is central to Ramp;D-based growth models. This paper empirically investigates the knowledge production function and intertemporal spillover effects using cointegration techniques. Time-series evidence suggests there are two long-run cointegrating relationships....

The economic prosperity of a region is largely dependent on the accumulation and diffusion of knowledge. In this paper, the scale effects as well as the resource reallocation effects of intra- and interregional knowledge transmission are analysed. Within a model, the optimal levels of knowledge...

We present a macroeconomic growth model in which investment in physical capital exhibits positive externalities which raise the stock of knowledge. Treating physical capital and knowledge as two separate variables, we show that the model can generate endogenous growth. It is demonstrated that...

This paper revisits the debate about the appropriate differential equation that governs the evolution of knowledge in models of endogenous growth. We argue that the assessment of the appropriateness of an equation of motion should not only be based on its implications for the future, but that it...
