A note on binary strategy-proof social choice functions

Basile, Achille; De Simone, Anna; Tarantino, Ciro - In: Games 13 (2022) 6, pp. 1-19

Let 𝝫𝑛 be the set of the binary strategy-proof social choice functions referred to a group of n voters who are … the analogous number of social choice functions when only strict preferences are admitted. A comparison is given for the … known values. Based on our results, we present a graphical description of the binary strategy-proof social choice functions …

A characterization of single-peaked preferences via random social choice functions

Chatterji, Shurojit; Sen, Arunava; Zeng, Huaxia - In: Theoretical Economics 11 (2016) 2, pp. 711-733

The paper proves the following result: every path-connected domain of preferences that admits a strategy-proof, unanimous, tops-only random social choice function satisfying a compromise property, is single-peaked. Conversely, every single-peaked domain admits a random social choice function...

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...

Further results on dictatorial domains

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...
