Pairwise partition graphs and strategy-proof social choice in the exogenous indifference class model

Pramanik, Anup; Sen, Arunava - 2014

In this paper we consider the exogenous indifference classes model of Barberá and Ehlers (2011) and Sato (2009) and analyze further the relationship between the structure of indifference classes across agents and dictatorship results. The key to our approach is the pairwise partition graph. We...

Symmetry vs. complexity in proving the Muller-Satterthwaite theorem

Ninjbat, Uuganbaatar - In: Economics Bulletin 32 (2012) 2, pp. 1434-1441

In this short note, we first provide two rather straightforward proofs for the Muller - Satterthwaite theorem in the baseline cases of 2 person 3 alternatives, and 2 person n â‰¥ 3 alternatives. We also show that it suffices to prove the result in the special case of 3 alternatives (with...

Group strategy-proof social choice functions with binary ranges and arbitrary domains: characterization results

Barberà, Salvador; Berga, Dolors; Moreno, Bernardo - Departament d'Economia i Història Econòmica, … - 2010

We define different concepts of group strategy-proofness for social choice functions. We discuss the connections … between the defined concepts under different assumptions on their domains of definition. We characterize the social choice … functions that satisfy each one of them and whose ranges consist of two alternatives, in terms of two types of basic properties. …

Sincere and sophisticated players in an equal-income market

Velez, Rodrigo A. - In: Journal of Economic Theory 157 (2015) C, pp. 1114-1129

We study the simultaneous direct revelation mechanism associated with each equal-income competitive social choice function in the allocation of objects and money among sincere and strategic agents. Strategic agents take advantage of sincere agents. They non-cooperatively coordinate on the...
