A characterization of the top-trading-cycles mechanism for housing markets via respecting-improvement
在Shapley-Scarf住房市场模型中，首次利用尊重改进性质刻画了顶级交易循环（TTC）机制，证明它是唯一同时满足配对效率、尊重改进和防策略操纵的机制。
We provide the first characterization of the prominent top-trading-cycles (TTC) mechanism in the Shapley–Scarf housing market model (Shapley and Scarf, 1974) that uses respecting-improvement . Specifically, we show that for strict preferences, the TTC mechanism is the unique mechanism satisfying pair-efficiency , respecting-improvement , and strategy-proofness .
