Until now, in models of endogenous growth with physical capital, human capital and R&D such as in Arnold [Journal of Macroeconomics 20 (1998)] and followers, steady-state growth is independent of innovation activities. We introduce absorption in human capital accumulation and describe the...

A growth model with endogenous innovation and accumulation of high-tech and low-tech human capital is developed. The model accounts for a recently established fact about human capital composition, which stated that \the richest countries are investing proportionally less than middle income...

The convergence features of an Endogenous Growth model with Physical capital, Human Capital and R&D have been studied. We add an erosion effect (supported by empirical evidence) to this model, and fully characterize its convergence properties. The dynamics is described by a fourth-order system...

We use a set of established growth models, which simultaneously include human capital and R&D, to show that the effect of mortality rate in human capital accumulation is quantitatively more important than the effect of perfectly guaranteed patents on research. First, we show that the effect of...

The effect of human capital composition on growth and development has been somewhat neglected in economic literature. However, evidence has suggested the importance of engineering and technical skills to economic growth and international organizations had suggested their shortage in developed...

Research and Development (R&D) endogenous growth models predict and most evidence show that investment in R&D increase with economic development. We consider the type of human capital mainly used in research labs and show that the richest countries are investing proportionally less than middle...

There is a family of models with Physical, Human capital and R&D for which convergence properties have been discussed (Arnold, 2000a; G´omez, 2005). However, spillovers in R&D have been ignored in this context. We introduce spillovers in this model and derive its steady-state and stability...

The years following the Second World War are those of greatest economic growth in Europe. If the countries of the Iberian Peninsula, neutral in the conflict and ruled by dictatorial regimes, enjoyed that growth and had participated in the convergence phenomenon, Ireland, also neutral but...
