Abstract

We study the house allocation with existing tenants model (Abdulkadiroglu and Sonmez, 1999) and consider rules that allocate houses based on priorities. We introduce a new acyclicity requirement and show that for house allocation with existing tenants a top trading cycles (TTC) rule is consistent if and only if its underlying priority structure satis es our acyclicity condition. Next we give an alternative description of TTC rules based on ownership-adapted acyclic priorities in terms of two speci c rules,YRMH-IGYT (you request my house - I get your turn) and ecient priority rules,that are applied in two steps. Moreover, even if no priority structure is a priori given,we show that a rule is a top trading cycles rule based on ownership-adapted acyclic priorities if and only if it satis es Pareto-optimality, individual-rationality, strategy-proofness, consistency, and either reallocation-proofness or non-bossiness.
