We consider a discrete-time two-sector Cobb-Douglas economy with positive sector specific external effects. We show that indetermincay of steady states and cycles can easily arise with constant or decreasing social returns to scale, and very small market imperfections. This is in sharp contrast...

This note constructs a neoclassical growth model of endogenous intergenerational altruism along the lines of Mulligan (1997). It is shown that individuals accumulate altruism in the long run whenever the rate at which concern is accumulated is sufficiently high, and that the endogenous formation...

Nous considerons un modele dans lequel l'accumulation de capital huamin depend de deux inputs: l'effort prive d'education des individus et le poids du systeme educatif public represente par son taux d'encadrement. Ce dernier depend notamment du pourcentage d'enseignants qui est choisi par les...

This paper examines interactions between education policy and growth. The analysis is carried out in an OLG model with two types of individuals: skilled and unskilled.

We consider an overlapping generations model of small open economy with Harrod neutral technical progress. If the interest rate is less that the growth rate, intergenerational public transfers increase welfare of some generations and reduce welfare of others.

This paper analyzes the macroeconomic effects of the patent system within the framework of an endogenous growth model with new products development. We assume that patents not only represent a commercial protection for innovators but also entail a partial property right on information.

This paper discusses the influence of technological externalities on the dynamic properties of accumulation paths in a two-sector growth model in discrete time.

We construct a R&D based endogenous growth model within an overlapping generations framework. We study the properties of the long run growth rate. We define endogenous growth as an equilibrium in which the long run growth rate is always stricly larger than zero. Then, we show that endogenous...

This article is interested in the scope for indeterminacies that originate from capital stock externalities in the technological set of the reference model of the multisectoral optimal growth literature. Sufficient conditions for local indeterminacies and oscillations are established and rest on...
