Designing practical mechanisms for indivisible good allocation

In indivisible good economies such as auction or matching, we studied the problem of designing economic mechanisms。For example, in an auction model without the quasi-linearity assumption on preferences, we offered an(axiomatic) characterization of second price auctions on the basis of equity and strategy-proofness。Furthermore, we characterized a rule that is stable and one-sided strategy-proof rule in a matching model。We also characterized the uniform rule on the basis of a weak version of strategy-proofness in allotment economies。In our discussions, we weakened various assumptions or conditions to obtain practical mechanisms.
