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...

Equitable Preference Relations on Infinite Utility Streams

Dubey, Ram Sewak; Laguzzi, Giorgio - 2021

We propose generalized versions of strong equity and Pigou-Dalton transfer principle. We study the existence and the real valued representation of social welfare relations satisfying these two generalized equity principles. Our results characterize the restrictions on one period utility domains...

A complete and strongly anonymous leximin relation on infinite streams

Asheim, Geir B.; Zuber, Stéphane - 2011

Various extensions of the leximin order to the infinite dimensional setting have been suggested. They relax completeness and strong anonymity. Instead, by removing sensitivity to generations at infinite rank this paper defines a complete and strongly anonymous leximin relation on infinite...

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...

Level r consensus and stable social choice

Mahajne, Muhammad; Nitsan, Shemuʾel; Volij, Oscar - 2014

We propose the concept of level r consensus as a useful property of a preference profile which considerably enhances the stability of social choice. This concept involves a weakening of unanimity, the most extreme form of consensus. It is shown that if a preference profile exhibits level r...
