A l’heure de l’économie du savoir et de la connaissance, l’éducation est devenue un enjeu majeur et l’enseignement a acquis une place centrale dans le processus de production d’éducation. Dans ces conditions, sont recherchés les moyens d’augmenter la performance des enseignants...

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 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...

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...

The articles gives new answers to the following questions : One, what can be potential source of the twin-peaks of economi growth ? Two, why were some of the countries that were believed to belong to the group of low steady state countries (like Taiwan, South Korea, Japan, etc) able to reach a...

This paper considers a three-overlapping-generations model of endogeneous growth wherein human capital is the engine of growth. It first contrasts the ‘laissez-faire’ and the optimal solutions. Three possible accumulation regimes are distinguished. Then it discusses a standard set of...

We endogenize the discount rate via a broad measure of wealth and provide empirical evidence that wealth the discount rate negatively. We demonstrate that the Pontryagin conditions require positive felicity for intuitive results, whereas the concavity of the Hamiltonian requires negative...

In a competitive overlapping generation model, underutilization of labor and equipment can be due to the combinaison of irreversibility of human capital, physical capital and technology with idiosyncratic productivity shocks. Irreversibilities and uncertainty generate an inefficient allocation...

In an unionized OLG model, it is shown that steady-state underutilization of labour and equipment can be due to the combinaison of the following elements : (i) Irreversibility of capital, technology and skill decision, (ii) Firm specific shocks on productivity. The presence of unions is neither...
