Characterizing TTC via endowments-swapping-proofness and truncation-proofness
In the object reallocation problem introduced by Shapley and Scarf (1974), Fujinaka and Wakayama (2018) showed that Top Trading Cycles (TTC) is the unique rule satisfying individual rationality, strategy-proofness, and endowments-swapping-proofness. We show that the uniqueness remains true if strategy-proofness is weakened to truncation-proofness.
期刊介绍：
Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
