Securely Implementable Social Choice Functions in Divisible and Non-Excludable Public Good Economies with Quasi-Linear Utility Functions
Nishizaki, Katsuhiko - 2016
This paper studies the possibility of secure implementation (Saijo, T., T. Sjöström, and T. Yamato (2007) "Secure Implementation," Theoretical Economics 2, pp. 203-229) in divisible and non-excludable public good economies with quasi-linear utility functions. Although Saijo, Sjöström, and...

A representative individual from arrovian aggregation of parametric individual utilities
Herzberg, Frederik - 2009
This article investigates the representative-agent hypothesis for an infinite population which has to make a social choice from a given finite-dimensional space of alternatives. It is assumed that some class of admissible strictly concave utility functions is exogenously given and that each...

Concavity of Utility, Concavity of Welfare, and Redistribution of Income
Kaplow, Louis - 2003
The marginal social value of income redistribution is understood to depend on both the concavity of individuals' utility functions and the concavity of the social welfare function. In the pertinent literatures, notably on optimal income taxation and on normative inequality measurement, it seems...

Interpersonal Comparisons of Utility : An Algebraic Characterization of Projective Preorders and Some Welfare Consequences
Candeal Haro, Juan Carlos; Indurain, E.; Molina, Jose … - 2021
It is shown that any completely preordered topological real algebra admits a continuous utility representation which is an algebra-homomorphism (i.e., it is linear and multiplicative). As an application of this result, we provide an algebraic characterization of the projective (dictatorial)...

Extended Gini index
Dubey, Ram Sewak; Laguzzi, Giorgio - 2022
We propose an extended version of Gini index defined on the set of infinite utility streams, $X=Y^\N$ where $Y\subset \R$.For $Y$ containing at most finitely many elements, the index satisfies the generalized Pigou-Dalton transfer principles in addition to the anonymity axiom

Judgment aggregation theory can entail new social choice results
