The purpose of this paper is to improve our understanding of government solvency in OLG models with a given sequence of government expenditures. In our view, public debt is allowed if its level does not preclude the existence of a competitive equilibrium. We first consider the case where the...

This paper studies macroeconomic consequences of the development of pension funds, assuming they hold a significant share of capital assets. We assume that this concentration introduces imperfect competition, that lowers wages and increases capital return. We show that pension funds tend to...

[fre] Qualité des biens, croissance et cycle du produit dans un modèle à générations imbriquées. . L'article présente un modèle de croissance endogène, dans le cadre d'un modèle à générations imbriquées. La croissance vient de l'activité de recherche des firmes, activité qui leur...

[fre] Cash-in-advance constraints in the overlapping generations model : neutrality of monetary policies and macro-dynamics. . This article is concerned with the role of money in an O.L.G. model. Money is introduced through a cash-in-advance constraint. We show that money is super-neutral if the...

[fre] Une présentation simple des dynamiques complexes. . Sous sa forme la plus simple, le modèle à générations imbriquées utilise les propriétés dynamiques des évolutions non linéaires en dimension un. Dans l'étude de ce modèle, nous explorons systématiquement ces propriétés et...

This paper provides a detailed study of a simple life-cycle consumption model with quasi-hyperbolic discounting and an imperfect financial market. It gives a complete characterization of savings behaviors. The joint assumptions of quasi-hyperbolic discount factors and no-borrowing constraints...

Pareto-efficiency of the competitive equilibrium is studied for a simple economy with overlapping generations and endogenous fertility. For CES utility and production functions, the properties of the economy are closely related to the two elasticities of substitution. The competitive equilibrium...

This paper suggests a new explanation for changes in economic and population growth with a long run perspective, emphasizing the role of land in the development process. Starting from a pre-industrialization state called the "Malthusian regime&qot;, land and labor are the main production factors....
