Four axioms are introduced in order to characterize the family of pair-based decomposable inequality measures, which is embraced in the class of weakly decomposable inequality measures. Three axioms, namely, normalization by pairs, aggregation by pairs, and decomposition by pairs enable the...

The goal of this paper is to contribute to the economic literature on ethnic and cultural diversity by proposing a new index that is informationally richer and more flexible than the commonly used ‘ethno-linguistic fractionalization’ (ELF) index. We characterize a measure of diversity among...

Cet article s'intéresse aux modèles non-unitaires de comportement du ménage. Ces modèles supposent explicitement que le ménage est composé de plusieurs personnes ayant des préférences distinctes. Ils se classent alors en deux catégories principales: d'une part, les modèles coopératifs...

In the present paper, we adopt the collective approach to consumer behavior-which supposes that each household member is characterized by his/her own preferences and that the decision process results in Pareto-efficient outcomes-and assume, in addition, that agents are egoistic and consumption...

Single-peaked preferences have played an important role in the literature ever since they were used by Black (1948) to formulate a domain restriction that is sufficient for the exclusion of cycles according to the majority rule. In this paper, we approach single-peakedness from a...

This paper presents a new theory of random consumer demand. The primitive is a collection of probability distributions, rather than a binary preference. Various assumptions constrain these distributions, including analogues of common assumptions about preferences such as transitivity,...

Although the theory of greatest-element rationalizability and maximal-element rationalizability under general domains and without full transitivity of rationalizing relations is well-developed in the literature, these standard notions of rational choice are often considered to be too demanding....

In this paper, we present a collective model of household demand based on Pareto-efficiency. In addition, we suppose that (i) each household member is egoistic and consumption is purely private, (ii) there is a set of distribution factors and (iii) there is one exclusive good. Then we derive the...

Récemment, un nouveau cadre théorique d'analyse s'est développé dans le but d'analyser les comportements des ménages avec deux conjoints. Cette approche, qualifiée de modèle collectif, suppose que chaque conjoint a des préférences individuelles et que les choix du ménage sont...
