Web21 Jul 2016 · "Ordinal mechanisms" are systematic procedures to make such decisions based on the agents' preference orders over the alternatives. A mechanism is "strategyproof" if it makes truthful... WebTwo important (randomized) matching mechanisms are Random Serial Dictatorship (RSD) and Probabilistic Serial Rule (PS) . Both mechanisms have important economic properties and are practical to implement. The RSD mechanism has strong truthful incentives but …

WebRandom priority (RP), also called Random serial dictatorship (RSD), is a procedure for fair random assignment - dividing indivisible items fairly among people.. Suppose partners have to divide (or fewer) different items among them. Since the items are indivisible, some partners will necessarily get the less-preferred items (or no items at all). RSD attempts to … WebThe system and method provides new authentication mechanisms that allow any entity to publicly verify a proof attesting the correctness of primitive set operations such as intersection, union, subset and set difference. Based on a novel extension of the security properties of bilinear-map accumulators as well as on a primitive called ...
WebWith binary utilities, the PS-lottery algorithm is group-strategyproof, ex-ante PO, ex-ante EF and ex-post EF1. These combinations of properties are best possible: it is impossible to … Webde ne a new notion of e ciency, called ordinal e ciency, and prove that the probabilistic serial mechanism nds an envy-free ordinally e cient assignment. However, the restrictive ... we show that on the full preference domain it is impossible for even a weak strategyproof mechanism to nd a random assignment that is both ordinally e cient and ...
WebSevere impossibility results restrict the design of strategyproof random assign-ment mechanisms, and trade-offs are necessary when aiming for more demanding efficiency requirements, such as ordinal or rank efficiency. ...

However, the class of sequential dictatorships mechanisms no longer character-izes all non-bossy, Pareto efficient, and strategyproof social choice mechanisms. To address this issue, Pápai [41] and Hatfield [27] stud-ied the multiple assignment problem where objects are assigned to
