Group strategy-proofness in private good economies without money: matching, division and house allocation

Abstract: We observe that three salient solutions to matching, division and house allocation problems are not only (partially) strategy proof, but (partially) group strategy-proof as well, in appropriate domains of de.nition. That is the case for the Gale-Shapley mechanism, the uniform rule and the top trading cycle solution, respectively. We embed these three types of problems into a general framework. We then notice that the three rules, as well as many others, do share a common set of properties, which together imply their (partial) group strategy-proofness. This proves that the equivalence between individual and group strategy-proofness in all these cases is not a fortuitous event, but results from the structure of the functions under consideration.
