On the optimality of progressive income redistribution
(Université de Montréal. Département de sciences économiques., 2012-08)
We compute the optimal non-linear tax policy for a dynastic economy with uninsurable risk, where generations are linked by dynastic wealth accumulation and correlated incomes. Unlike earlier studies, we find that the optimal ...
Multi-Profile Intertemporal Social Choice
(Université de Montréal. Département de sciences économiques., 2012-08)
We provide a brief survey of some literature on intertemporal social choice theory in a multi-profile setting. As is well-known, Arrow’s impossibility result hinges on
the assumption that the population is finite. For ...
Strategy-proof preference aggregation
(Université de Montréal. Département de sciences économiques., 2012-08)
An aggregation rule maps each profile of individual strict preference orderings
over a set of alternatives into a social ordering over that set. We call such a rule strategyproof if misreporting one’s preference never ...
Strategy-proofness makes the difference: deferred-acceptance with responsive priorities
(Université de Montréal. Département de sciences économiques., 2012-09)
In college admissions and student placements at public schools, the admission decision can be thought of as assigning indivisible objects with capacity constraints to a set of students such that each student receives at ...
Some effects of asymmetries in a common pool natural resource oligopoly
(Université de Montréal. Département de sciences économiques., 2012-08)
Nous envisageons le cas d'une ressource naturelle renouvelable exploitée en commun par des firmes qui se concurrencent à la fois dans le marché du produit et dans l'exploitation de la ressource. Nous montrons que ...
Intertemporal Material Deprivation
(Université de Montréal. Département de sciences économiques., 2012-06)
Individual well-being is multidimensional and various aspects of the quality of life
need to be jointly considered in its measurement. The axiomatic literature on the
subject has proposed many indices of multidimensional ...
Did Gold Remain Relevant in the Post-1971 International Monetary System?
(Université de Montréal. Département de sciences économiques., 2012-05)
The central hypothesis to be tested is the relevance of gold in the determination of the value of the US dollar as an international reserve currency after 1971. In the first section the market value of the US dollar is ...
Single-plateaued choice
(Université de Montréal. Département de sciences économiques., 2012-05)
Single-plateaued preferences generalize single-peaked preferences by allowing for multiple best elements. These preferences have played an important role in areas such as voting, strategy-proofness and matching problems. ...

Single-plateaued preferences generalize single-peaked preferences by allowing for multiple best elements. These preferences have played an important role in areas such as voting, strategy-proofness and matching problems. ...
Extensive Social Choice and the Measurement of Group Fitness in Biological Hierarchies
(Université de Montréal. Département de sciences économiques., 2012-07)
Extensive social choice theory is used to study the problem of measuring group fitness in a two-level biological hierarchy. Both fixed and variable group size are considered. Axioms are identified that imply that the group ...
