چکیده

We show that feasible elimination procedures (Peleg, 1978) can be used to select k from m alternatives. An important advantage of this method is the core property: no coalition can guarantee an outcome that is preferred by all its members. We also provide an axiomatic characterization for the case k = 1, using the conditions of anonymity, Maskin monotonicity, and independent blocking. Finally, we show for any k that outcomes of feasible elimination procedures can be computed in polynomial time, by showing that the problem is computationally equivalent to finding a maximal matching in a bipartite graph.

Choosing k from m: Feasible elimination procedures reconsidered

We show that feasible elimination procedures (Peleg, 1978) can be used to select k from m alternatives. An important advantage of this method is the core property: no coalition can guarantee an outcome that is preferred by all its members. We also show that the problem of determining whether a specific k-tuple can result from a feasible elimination procedure is computationally equivalent to the...

Feasible Elimination Procedures in Social Choice: an Axiomatic Characterization

Feasible elimination procedures (Peleg, 1978) play a central role in constructing social choice functions which have the following property: in the associated game form, for any preference profile there exists a strong Nash equilibrium resulting in the sincere outcome. In this paper we provide an axiomatic characterization of the social choice correspondence resulting from applying feasible eli...

Bezalel Peleg and Hans Peters: Strategic social choice. Stable representations of constitutions

Many sincere compliments should be addressed to Bezalel Peleg and Hans Peters, the authors of the book Strategic Social Choice. Stable Representations of Constitutions published last year by Springer. Our experience with the previous books of these authors on game theory (Peleg 1984; Peleg and Sudhölter 2003; Peters 1992, 2008) induces very high expectations with respect to this jointly written...

Constitutional implementation of social choice correspondences

A game form constitutionally implements a social choice correspondence if it implements it in Nash equilibrium and, moreover, the associated effectivity functions coincide. This paper presents necessary and sufficient conditions for a unanimous social choice correspondence to be constitutionally implementable, and sufficient and almost necessary conditions for an arbitrary (but surjective) soci...
