Social choice of convex risk measures through Arrovian aggregation of variational preferences

Herzberg, Frederik - Institut für Mathematische Wirtschaftsforschung, … - 2010

It is known that a combination of the Maccheroni-Marinacci-Rustichini (2006) axiomatisation of variational preferences with the Föllmer-Schied (2002,2004) representation theorem for concave monetary utility functionals provides an (individual) decision-theoretic foundation for convex risk...

General aggregation problems and social structure: A model-theoretic generalisation of the Kirman-Sondermann correspondence

Herzberg, Frederik; Eckert, Daniel - 2009

This article proves a very general version of the Kirman-Sondermann [Journal of Economic Theory, 5(2):267-277, 1972] correspondence by extending the methodology of Lauwers and Van Liedekerke [Journal of Mathematical Economics, 24(3):217-237, 1995]. The paper first proposes a unified framework...
