Private property in land has often been criticized because it is supposed to bring about a waste of productive resources weakening economic growth. Indeed, because it is non reproductible, land earns a rent which increases in a growing economy and whose capitalization decreases the "productive"...

This paper investigates the macroeconomic portfolio implications of monopoly rents. We make use of a two-sectors overlapping generations model with a Cournot oligopoly in one sector. We show that when the competitive equilibrium is characterized by under-capitalization with respect to the golden...

A major issue in reforming previously planned economies is the creation of assets markets. In this paper, it is argued that the mere characteristics of the assets to be privatized matter. Indeed, private ownership of land. It is the purpose of this paper to provide a theory of such rate. We make...

Cet article étudie les effets sur l'épargne d'une incertitude sur le taux de croissance de la population dans un modèle à générations imbriquées. Nous montrons que les hypothèses nécessaires à la formation d'une épargne individuelle de précaution ne suffisent pas dans un cadre...

Ce papier présente certains développements théoriques récents sur la crédibilité des politiques économiques. Après avoir souligné les limites des analyses traditionnelles à la Barro Gordon, on expose les différentes approches utilisées pour résoudre les problèmes de crédibilité....

This paper addresses the issue of the determination of return to capital when there is no exogenous ownership in firms. Hahn and Solow have proposed a notion of equilibrium for this setting and we consider this notion from a partial equilibrium point of view (i.e. under the assumption that the...

This paper is a study of money in overlapping generations models with cash-in-advance constraints. We first offer a brief review of different features of the cash-in-advance constraint. Then we propose a general formulation and study the neutrality of money. We show that both neutrality and...

This paper relies on Benhabib (1996)’ s immigration model to analyze the political sustainability of selling immigration permits, an idea proposed by Gary Becker. To simplify the analysis, we focus on the effects of immigration flows on input prices. We find that immigration quotas almost...
