In this paper, we develop a model in which human being constitutes the sole asset and is a production factor which can be combined with a fixed factor, say land, to produce a homogeneous commodity. Saving, so to speak, can only be made through having children, the number of which is an...

In this paper, we develop a growth model in which human being is a production factor which can be combined with a fixed factor, say land, to produce a homogeneous commodity. Saving, so to speak, can only be made through having children, the number of which is an endogenous decision to the...

In this paper, we investigate a dual class of bi-polarization indices, namely rank-dependent bi-polarization indices. We show that these indices may be characterized with the generalized positional transfer sensitivity property. We find necessary and sufficient conditions in order to identify...

This paper analyzes the definition of economic efficiency. The standard definition used in economic literature is the Pareto Optimum which is based in the space of individual utilities. This paper proposes new definitions based on alternative spaces. The paper also introduces a dominance...

Dans cette note, nous développons un modèle dans lequel l'embauche d'un travailleur sans expérience comporte une caractéristique de bien public en révélant à tous les employeurs le type du travailleur. Dans ce contexte, nous démontrons que l'embauche de travailleurs sans expérience est...

An axiomatic approach is used to propose a measure of extreme poverty which is not only multidimensional in nature, but also recognizes the fact that there are interaction effects between different deprivations, and that the length of time during which deprivations are felt may also have a...

The concept of horizontal inequality is generally used in economics to refer to the unequal treatment of equal individuals by the fiscal system. For example, an economic system can treat unequally two individuals who hold identical levels of production factors. The following note will present a...

We propose simple graphical methods to identify poverty-reducing marginal reforms of transfer programs. The methods are based on Program Dominance curves that display cumulative program benefits weighted by powers of poverty gaps. These curves can be decomposed simply as sums of targeting...

A new tool is presented to test for the robustness of the impact on poverty of marginal tax reforms for pairs of commodities. Consumption Dominance Curves exist for every order of stochastic dominance while the more standard concentration curves are only linked to the second order of dominance....
