Mondialisation, globalisation, internationalisation autant de concepts qui ont leur signification propre, même si la frontière de démarcation est souvent floue. Le propos ne sera pas d'en faire l'exégèse ni d'en préciser le contenu mais de considérer, au départ, le phénomène...

Convex output set is a common hypothesis in production theory and especially in empirical applications. This often seems to be taken for granted without any reference to returns to scale. However increasing returns to scale have implied a necessary and fundamental revision of general equilibrium...

Power is absent in many economic studies, though everyone knows that social and economic agents often look to increase their own influence on the behaviour of others. In this paper, a power structure is associated to an economic structure, the power resulting from the influence transmitted and...

Convex output set is common hypothesis in production theory and empirical applications such as the Data Development Analysis. This seems to be taken for granted without any reference to returns to scale. This paper focuses on the relation between returns to scale and the nature of output...

Convex output set is common hypothesis in both production theory and empirical applications such as the Data Envelopment Analysis. It seems to be taken for granted without any reference to returns to scale. This paper presents simulations for joint Cobb-Douglas production functions. The output...

La globalisation, terme utilisé à tort et à travers, est souvent accusée de tous les maux par la presse et les livres à grand tirage. Bien que les caractéristiques fondamentales de la globalisation ne soient plus guère contestées, les opinions divergent quant aux effets de la...

Cette introduction aux modèles de croissance endogène comporte trois parties. La première partie est consacrée aux caractéristiques de la croissance exogène, plus particulièrement au modèle de Solow et à ses développements. La seconde partie présente le modèle de Ramsey-Koopmans dans...

Convex output set is common hypothesis in production theory and empirical applications such as the Data Envelopment Analysis. This seems to be taken for granted without any reference to returns to scale. This paper presents the demonstration for joint Cobb-Douglas production frontiers with...

In traditional theory technical progress as a cause of growth is not only artificially separated from increase in factor endowments but it is also exogenous, in the sense that technological improvements fall on the economy like manna from heaven. Technical progress, however, usually derives from...

Depuis plus de vingt ans, la PAC a accentué les disparités entre les agriculteurs et entre les différentes régions agricoles. L'objet de cette étude est à la fois de dresser un bilan de la PAC et d'identifier les évolutions indispensables que la PAC doit encore connaître. Les réformes...
