Robust design in monotonic matching markets : a case for firm-proposing deferred-acceptance
(Université de Montréal. Département de sciences économiques., 2018-05)
We study two-sided matching markets among workers and firms. Workers seek one position at a firm but firms may employ several workers. In many applications those markets are monotonic: leaving positions unfilled is costly ...
Gale's fixed tax for exchanging houses
(Université de Montréal. Département de sciences économiques., 2018-06)
We consider the taxation of exchanges among a set of agents where each agent owns one object. Agents may have different valuations for the objects and they need to pay taxes for exchanges. Using basic properties, we show ...
Robust minimal instability of the top trading cycles mechanism
(Université de Montréal. Département de sciences économiques., 2020-03)
In the context of priority-based resource allocation, we formulate methods to compare assignments in terms of their stability as binary relations (on the set of possible assignments) that depend on the preference and the ...
Organizing time banks: Lessons from matching markets
(Université de Montréal. Département de sciences économiques., 2018-07)
A time bank is a group of people that set up a common platform to trade services among themselves. There are several well-known problems associated with this type of time banking, e.g., high overhead costs and difficulties ...
Dynamic refugee matching
(Université de Montréal. Département de sciences économiques., 2018-10)
Asylum seekers are often assigned to localities upon arrival using uninformed matching systems, which lead to inefficient and unfair allocations. This paper proposes an informed dynamic mechanism as an intuitive and ...
Sharing a River among Satiable Countries
(Université de Montréal. Département de sciences économiques., 2006-07)
With diminishing global water reserves the problem of water allocation becomes increasingly important. We consider the problem of efficiently sharing a river among a group of satiable countries. Inducing countries to ...
Free Triples, Large Indifference Classes and the Majority Rule
(Université de Montréal. Département de sciences économiques., 2007-03)
Blocking pairs versus blocking students: Stability comparisons in school choice
(Université de Montréal. Département de sciences économiques., 2020-04)
It is known that there are school choice problems without an efficient and stable assignment. We consider comparing assignments in terms of their stability by comparing their sets of blocking (student-school) pairs or ...
Oligarchies in Spatial Environments
(Université de Montréal. Département de sciences économiques., 2007)
In spatial environments we consider social welfare functions satisfying Arrow’s requirements, i.e. weak Pareto and independence of irrelevant alternatives. Individual preferences measure distances between alternatives ...
Strategy-proof and envyfree random assignment
(Centre interuniversitaire de recherche en économie quantitative, 2020-12-22)
We study the random assignment of indivisible objects among a set of agents with strict
preferences. We show that there exists no mechanism which is strategy-proof, envyfree
and unanimous. Then we weaken the latter ...
