A Class of Two-Group Polarization Measures
(Université de Montréal. Département de sciences économiques., 2007)
Poverty and Time
(Université de Montréal. Département de sciences économiques., 2008-03)
We examine the measurement of individual poverty in an intertemporal context. In contrast to earlier contributions, we assign importance to the persistence in a state of poverty and we characterize a class of individual ...
Multi-Profile Intergenerational Social Choice
(Université de Montréal. Département de sciences économiques., 2008-06)
Ferejohn and Page transplanted a stationarity axiom from Koopmans’ theory of impatience into Arrow’s social choice theory with an infinite horizon and showed that the Arrow axioms and stationarity lead to a dictatorship ...
A Generalized Index of Fractionalization
(Université de Montréal. Département de sciences économiques., 2008-01)
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 ...
Rationality, External Norms and the Epistemic Value of Menus
(Université de Montréal. Département de sciences économiques., 2008-06)
Ever since Sen’s (1993; 1997) criticism on the notion of internal consistency or menu independence of choice, there exists a widespread perception that the standard revealed preference approach to the theory of rational ...
A Characterization of Consistent Collective Choice Rules
(Université de Montréal. Département de sciences économiques., 2006-08)
We characterize a class of collective choice rules such that collective preference relations are consistent. Consistency is a weakening of transitivity and a strengthening of acyclicity requiring that there be no cycles ...
Decisive Coalitions and Coherence Properties
(Université de Montréal. Département de sciences économiques., 2009-03)
In a seminal contribution, Hansson has demonstrated that the family of decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter. If the population under consideration is infinite, his ...
Quasi-Transitive and Suzumura Consistent Relations
(Université de Montréal. Département de sciences économiques., 2009-03)
We examine properties of binary relations that complement quasi-transitivity and Suzumura consistency in the sense that they, together with the original axiom(s), are equivalent to transitivity. In general, the conjunction ...
Multidimensional Poverty and Material Deprivation
(Université de Montréal. Département de sciences économiques., 2009-08)
We examine the measurement of multidimensional poverty and material deprivation following the counting approach. In contrast to earlier contributions, dimensions of well-being are not forced to be equally important but ...
Consistent Relations
(Université de Montréal. Département de sciences économiques., 2006)
Consistency, a natural weakening of transitivity introduced in a seminal contribution by Suzumura (1976b), has turned out to be an interesting and promising concept in a variety of areas within economic theory. This paper ...
