While both DA-STB and DA-MTB mechanisms make it safe for students to reveal their true preferences, they naturally produce very di erent assignments.

WebThe deferred acceptance mechanism (DA) replaced the Boston mechanism (BM) in college admissions in China. In this paper, I compare the empirical performance of these two mechanisms in the Chinese context by developing an empirical model and applying it to college admissions in Guangxi, Hebei, and Sichuan provinces. Webby deferred acceptance, since both are Pareto e¢ cient for students. Thus, there is a tradeo⁄ between strategy-proofness and e¢ ciency, a tradeo⁄ that hinges on stability. Deferred acceptance with tie breaking, a stable mechanism, is on the e¢ cient frontier of all strategy-proof mechanisms. do you still have bursa after hip replacement

It is a truthful mechanism with strategic properties that make it particularly suitable to complex auctions such as the radio spectrum reallocation auction.
