We examine the dimension reduction method and prove that it could be isleading if we try to get some insight tinto the dynamics of the original system from the dynamics of the transformed system alone. The reduced system seemingly may give rise to a continuum multiplicity of steady states when,...

We study an extended version of the one-sector AK growth model introducing adjustment and maintenance costs. Agents are allowed to under-use the installed capital and to vary the depreciation rate. The model is analyzed using particular functional forms and is solved in closed-form. We find that...

Este estudio ofrece una evaluación empírica de los efectos económicos de las ayudas europeas de cohesión recibidas por España entre 1989 y 2006, lapso de tiempo que abarca los tres últimos periodos de programación financiera de la Unión Europea y a lo largo del cual nuestro país habrá...

The competitive equilibrium in an endogenous growth model is not Pareto-optimal nor environmentally sustainable in presence of pollution externalities, even if costly abatement activities are allowed to be endogenously decided. In this paper we introduce the possibility of an ecological...

In this paper we propose a method for solving in closed form a general class of non-linear modified Hamiltonian dynamic systems (MHDS). This method may be used to analyze some intertemporal optimization problems With a predetermined structure involving unbounded technological constraints. The...

A comprehensive study of the linkages between demographic and economic variables should not only account for vintage specificity but also incorporate the relevant economic and demographic decisions in a complete optimal control set-up. In this paper, a methodological set-up allowing to reach...

This paper analyzes the equilibrium dynamics of an AK-type endogenous growth model with vingage capital. The inclusion of vintage capital leads to oscillatory dynamics governed by replacement echoes, which additionally influence the intercept of the balanced growth path. These features, which...

We study how economic growth is affected by demographics in an overlapping generations model with a realistic survival law. Individuals optimally chose the dates at which they leave school to enter the labor market and at which they retire. Endoneous growth arises thanks to the accumulation of...
