This paper analyzes the link between the fact that fully endogenous growth models exhibit (or not) the non-desirable scale effects property and assumptions regarding the intensity of knowledge diffusion. In that respect, we extend a standard Schumpeterian growth model by introducing explicitly...

What is the social value of innovations in Schumpeterian growth models? This issue is tackled by introducing the concept of Lindahl equilibrium in a standard endogenous growth model with vertical innovations which is extended by explicitly considering knowledge diffusion on a Salop (1979)...

What is the social value of innovations in Schumpeterian growth models? This issue is tackled by introducing the concept of Lindahl equilibrium in a standard endogenous growth model with vertical innovations which is extended by explicitly considering knowledge diffusion. Assuming that knowledge...

By assuming that grandparents take care of grandchildren, in this paper we aim at studying the effects of longevity on economic growth in the basic OLG model with endogenous fertility. We show that a rise in longevity can actually reduce long-run growth. Moreover, we also find that an increasing...

This paper examines the implications of an environmental policy for growth performances. We develop a model where growth is driven by human capital accumulation. Firms invest in research to develop new technologies to reduce their pollution emissions and education is treated as product which not...

This paper exploits the formalization of a circular product differentiation model of Salop (1979) to propose an endogenous growth quality ladder model in which the knowledge inherent in a given sector can spread variously across the sectors of the economy, ranging from local to global influence....

We offer an analysis of the existence of a positive relationship between minimum wages and economic growth in a simple one-sector overlapping generations economy where the usual Romer-typed knowledge spill-over mechanism in production represents the engine of endogenous growth, in the case of...

This article analyses how long-run pay-as-you-go public pensions react to a change in fertility in the basic overlapping generations model of neoclassical growth. While it would seem well established both in the academic and political debates that the decline in fertility represents a...

This paper proposes a Schumpeterian growth model generalizing the existing theory : we exploit the formalization of a circular product differentiation model of Salop (1979) to take into account the fact that knowledge inherent in a given sector can diffuse variously among R&D sectors, ranging...
