Pramanik, Anup - 2014

This paper generalizes the results in Aswal et al. (2003) on dictatorial domains. This is done in two ways. In the first, the notion of connections between pairs of alternatives in Aswal et al. (2003) is weakened to weak connectedness. This notion requires the specification of four preference...

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...

ON QUASI-TRANSITIVE RATIONALITY OF FUZZY CHOICE FUNCTIONS

DESAI, SANTOSH - In: New Mathematics and Natural Computation (NMNC) 10 (2014) 01, pp. 91-102

In literature many researchers have studied full rationality of fuzzy choice functions. The aim of the present paper is … to discuss rationality of fuzzy choice functions with rationalization reflexive, complete and quasi-transitive. For this … purpose, we use fuzzy path independent property and fuzzy Condorcet property. We characterize rationality of fuzzy choice …

On the Necessity of Pairs and Triplets for the Equivalence between Rationality Axioms

He, Junnan - In: Economics: The Open-Access, Open-Assessment E-Journal 6 (2012) 2012-31, pp. 1-15

This paper is concerned with the axiomatic foundation of the revealed preference theory. Many well-known results in the literature rest upon the ability to choose over budget sets that contain only 2 or 3 elements. This paper shows that for any given choice function, many of the famous...

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...
