This paper gives an overview of the way the issue of poverty measurement is typically addressed in economics. After having briefly defined what is meant by poverty in economics, I examine successively the unidimensional approach to poverty based on the income or expenses, and the...

Using a model of bivariate decision under risk of disease, with separates the financial losses from the health losses, we analyse the curative demand for healthcare and the determinants of overconsumption care problem. We also study the demand for self-protection and the demand for...

This paper proposes and characterises a model of uncertainty averse preferences that can simultaneously accommodate three divergences from subjective expected utility: imprecision of beliefs (or ambiguity), imprecision of tastes (or multi utility), and state dependence of utility. Moreover, it...

We study portfolio allocation and characterize contracts issued by firms in the international financial market when investors exhibit ambiguity aversion and perceive ambiguity in assets issued in foreign locations. Increases in the variance of their risky production process cause firms to issue...

We decompose the generalized Lorenz order into a size and a distribution component. The former is represented by stochastic dominance, the latter by the standard Lorenz order. We show that it is always possible, given generalized Lorenz dominance between two distributions F and G, to find...

We reformulate Grandmont's and its successors' notion of behavioral heterogeneity such as to get the exact insensitivity of the aggregate budget share function with respect to changes in prices and income, instead of a mere approximate insensitivity. We propose a non parametric set-up such that,...

We give in this note an overview of the way income inequality is approached in economics.\r\nWe first recall the basic properties that any inequality index is required to possess and\r\nwe insist on the distinction between the indices of relative inequality and the indices of\r\nabsolute...

Presumably, foreign banks open subsidiaries and branches in Luxembourg to perform different tasks. This paper studies the balance sheet structure of banks in Luxembourg, testing for differences across groups and across periods. Non-parametric methods yield several findings. First, specialisation...

Les impôts et les transferts en espèces réduisent en France les inégalités de revenu plus que dans beaucoup d’autres pays de l’OCDE en raison de la taille importante des flux concernés. Mais le système est complexe dans son ensemble. Son efficacité pourrait être améliorée à bien...

In the standard consumption capital asset pricing model (CCAPM), the curvature of the investor's utility function captures two aspects of preferences: as the concavity of the function increases so does his aversion to risk as well as his desire to smooth consumption intertemporally. This...
