  • Decisive Coalitions and Coherence Properties 

    Bossert, Walter; Suzumura, Kotaro (Université de Montréal. Département de sciences économiques., 2009-03)
    In a seminal contribution, Hansson has demonstrated that the family of decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter. If the population under consideration is infinite, his result implies the existence of ...
  • Multi-Profile Intertemporal Social Choice 

    Bossert, Walter; Suzumura, Kotaro (Université de Montréal. Département de sciences économiques., 2012-08)
    We provide a brief survey of some literature on intertemporal social choice theory in a multi-profile setting. As is well-known, Arrow’s impossibility result hinges on the assumption that the population is finite. For infinite populations, there exist ...
  • Product Filters, Acyclicity and Suzumura Consistency 

    Bossert, Walter; Suzumura, Kotaro (Université de Montréal. Département de sciences économiques., 2010-11-25)
    In a seminal contribution, Hansson (1976) demonstrates that the collection of decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter. He goes on to show that if transitivity is weakened to quasi-transitivity as ...
