This paper introduces &tao;-fairness as a compromise solution reconciling Pareto efficiency and equity in School Choice Problems. We show that, by considering a weak notion of equity that we refer to as ¿-equity, it is possible to contribute positively to solve an open debate, originated by the...

This paper provides three simple mechanisms to implement allocations in the core of matching markets. We analyze some sequential mechanisms which mimic matching procedures for many-to-one real life matching markets. We show that only core allocations should be attained when agents act...

We implement the core correspondence in Subgame Perfect Equilibrium using a simplesequential mechanism in which firms propose a salary to each worker (in the first stage). Then ,each worker accepts at most one proposal (second stage). Moreover, we show that, if agents'preferences are additive,...

This paper studies the sequential mechanisms which mimic matching procedures formany-to-one-real-life matching markets. We provide a family of mechanisms implementing thestudent´ optimal allocation in subgame perfect equibrium.

This paper studies a class of NTU coalition formation games in which every player's payoff depends only on the members of her coalition. We identify four natural conditions on individuals' preferences and show that, under each condition, stable (core) allocations exists.
