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...

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...

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...

En este artículo se discute el papel que juega la edad del capital en el crecimiento económico. Con este objetivo revisamos algunos resultados al respecto en modelos de crecimiento endógeno en los que el capital físico es heterogéneo por razón de la edad (vintage capital). Cuando las...

In this paper, we build up a general equilibrium model explicitly incorporating Schumpeterian growth à la Aghion and Howitt (1992) and a vintage capital structure in line with Solow (1960). Technological progress is embodied. We show that the investment rate is a fundamental determinant of the...
