Título: "Coalitional stability in matching problems with externalities and random preferences"

Expositor: Adriana Piazza (Universidad de Chile)

Resumen:
 
We study coalitional stability in matching problems with externalities,
including marriage markets, roommate problems, and Shapley-Scarf housing markets
as particular cases. When preferences are randomly determined, the probability
of having a coalitionally stable solution is positively affected by three
factors: the prudence of coalitionswhen evaluating a deviation, the social
connectedness of those that can react to it, and the incidence of externalities
in preferences. At the same time, this probability is negatively affected by the
number of agreements that agents can implement to block a matching. In this
context, if agents have a limited capacity to organize themselves into large
coalitions, then coalitional stability holds asymptotically even when
individuals become less and less prudent as the population grows.

Joint work with Juan Pablo Torres-Martinez
