Cet article compare les différentes hypothèses d'altruisme qui ont été étudiées dans le cadre du modèle à générations imbriquées. Deux visions concurrentes de l'altruisme se côtoient. La première due à Barro [1974] est proche de l'intuition que l'on peut avoir des solidarités au...

This paper sets up a simple two-country overlapping generations madel to explore the interplay between education, taxation, and labour mobility and to assess the impact of education policies on human capital formation and long-run welfare in both the sending and the receiving country. It...

In the context of a stylised gaine theoretical framework of capital tax competition, we show that when repeated policy interactions are associated to a systematic punishment of the deviating policymaker, a coordinated outcome can be the solution to the non cooperative tax game. This resuit...

The principle of effective demand decomposes in two distinct propositions, one pertaining to the analysis of actual, the other to the analysis of equilibrium states. The authors suggest that Keynes' apparatus of aggregate supply and demand decomposes correspondingly in two pairs of aggregate...

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...

Sous l’hypothèse de prévisions parfaites et en horizon infini, nous proposons un modèle des choix de consommation d’un agent représentatif dont le revenu, à chaque période, se compose de son salaire et du rendement du stock d’actifs qu’il détient. Une partie de sa consommation est...

Given the difficulties of utilitarian and egalitarian social welfare functions in the context of intergenerational equity, an analysis directly based on the potential transfers that can be made between generations is proposed. A consumption path may be rejected if some transfers with infinite...

We address the issue of altruism when standard-of-living aspirations are transmitted from one generation to the other. In that case, the influence of altruistic parents is not limited to the bequest they could leave; indeed, they direct the evolution of children's aspirations toward raising their...

We analyze the effect of a constant debt policy on capital accumulation and provide an in-depth treatment of the dynamics in the economy of Diamond. We derive the conditions for avoiding a debt crisis in both the short-run and the long-run and provide geometrical tools to analyze the issue of...

We compare the dynamics under myopic foresight and under perfect foresight in an overlapping generations model with capital accumulation and two-period lived individuals. When the rational dynamics are defined and the myopic dynamics are monotonic, the study of myopic foresight allows to...
