In general, no rule satisfies the three central properties Pareto-efficiency, individual rationality, and strategy-proofness \\cite{Sonmez1999}. Recently, it was shown that Top Trading Cycles is $\\NP$-hard to manipulate \\cite{FujitaEA2015}, a relaxation of strategy-proofness. However, parameterized complexity is a more appropriate framework for this and other economic settings.
