A characterization of Top Trading Cycles under trading networks

Abstract

We consider an object reallocation problem within a specific class of trade restrictions. An agent can only receive the object of someone else connected to him, which is referred to as feasibility. We introduce a Network Augmented Top Trading Cycles (NTTC) mechanism. Our main result shows that a mechanism is NTTC if and only if it is feasible, individually rational, constrained efficient, and strategy-proof.
