Measuring Economic Insecurity
(Université de Montréal. Département de sciences économiques., 2009-03)
We provide a systematic treatment of the notion of economic insecurity, assuming that an individual’s sentiment of insecurity depends on the current wealth level and its variations experienced in the past. We think of ...
Sectoral Price Rigidity and Aggregate Dynamics
(Université de Montréal. Département de sciences économiques., 2009-02)
In this paper, we study the macroeconomic implications of sectoral heterogeneity and, in particular, heterogeneity in price setting, through the lens of a highly disaggregated multi-sector model. The model incorporates ...
Beyond Panel Unit Root Tests: Using Multiple Testing to Determine the Non Stationarity Properties of Individual Series in a Panel
(Université de Montréal. Département de sciences économiques., 2009-10)
Most panel unit root tests are designed to test the joint null hypothesis of a unit root for each individual series in a panel. After a rejection, it will often be of interest to identify which series can be deemed to be ...
Manipulation via Capacities Revisited
(Université de Montréal. Département de sciences économiques., 2009-03)
This paper revisits manipulation via capacities in centralized two-sided matching markets. Sönmez (1997) showed that no stable mechanism is nonmanipulable via capacities. We show that non-manipulability via capacities can ...
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 ...
Relative Egalitarianism and Related Criteria
(Université de Montréal. Département de sciences économiques., 2009-02)
We reconsider the problem of aggregating individual preference orderings into a single social ordering when alternatives are lotteries and individual preferences are of the von Neumann-Morgenstern type. Relative egalitarianism ...
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 ...
Toward a rational-choice foundation of non-additive theories
(Université de Montréal. Département de sciences économiques., 2009-09)
A classical argument of de Finetti holds that Rationality implies Subjective Expected Utility (SEU). In contrast, the Knightian distinction between Risk and Ambiguity suggests that a rational decision maker would obey the ...
The Impact of Recycling on the Long-Run Stock of Trees
(Université de Montréal. Département de sciences économiques., 2009-08)
Interest in recycling of forest products has grown in recent years, one of the goals being to conserve the stock of trees or possibly increase it to compensate for positive externalities generated by the forest and neglected ...
