  • BLACKORBY, Charles; BOSSERT, Walter; DONALDSON, David (2004)
    This note reexamines the single-profile approach to social-choice theory. If an alternative is interpreted as a social state of affairs or a history of the world, it can be argued that a multi-profile approach is inappropriate ...
  • BLACKORBY, Charles; BOSSERT, Walter; DONALDSON, David (2001)
    This paper proves a new representation theorem for domains with both discrete and continuous variables. The result generalizes Debreu's well-known representation theorem on connected domains. A strengthening of the standard ...
  • BOSSERT, Walter; QI, Chloe X.; WEYMARK, John A. (2012-09)
    In order to analyze a unicellular-multicellular evolutionary transition, a multicellular organism is identified with the vector of viabilities and fecundities of its constituent cells. The Michod–Viossat–Solari–Hurand–Nedelcu ...
  • BOSSERT, Walter; SUZUMURA, Kotaro (Université de Montréal, Département de sciences économiques, 2006-08)
    We characterize a class of collective choice rules such that collective preference relations are consistent. Consistency is a weakening of transitivity and a strengthening of acyclicity requiring that there be no cycles ...

  • BOSSERT, Walter; SPRUMONT, Yves; SUZUMURA, Kotaro (2002)
    Consistency of a binary relation requires any preference cycle to involve indifference only. As shown by Suzumura (1976b), consistency is necessary and sufficient for the existence of an ordering extension of a relation. ...
  • BOSSERT, Walter (2006)
    Consistency, a natural weakening of transitivity introduced in a seminal contribution by Suzumura (1976b), has turned out to be an interesting and promising concept in a variety of areas within economic theory. This paper ...
  • BOSSERT, Walter; BRAMS, Steven J.; KILGOUR, D. Marc (2000)
    It is well-known that non-cooperative and cooperative game theory may yield different solutions to games. These differences are particularly dramatic in the case of truels, or three-person duels, in which the players may ...
  • BOSSERT, Walter; SPRUMONT, Yves (2000)
    We provide a characterization of selection correspondences in two-person exchange economies that can be core rationalized in the sense that there exists a preference profile with some standard properties that generates the ...
  • BLACKORBY, Charles; BOSSERT, Walter; DONALDSON, David (2002)
    Critical-level generalized-utilitarian population principles with positive critical levels pro-vide an ethically attractive way of avoiding the repugnant conclusion. We discuss the axiomatic foundations of critical-level ...
  • 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 ...
  • BOSSERT, Walter; D'AMBROSIO, Conchita; PERAGINE, Vito (2004)
    Social exclusion manifests itself in the lack of an individual’s access to functionings as compared to other members of society. Thus, the concept is closely related to deprivation. We view deprivation as having two basic ...
  • BOSSERT, Walter; SUZUMURA, Kotaro (2005)
    The rationalizability of a choice function on an arbitrary domain under various coherence properties has received a considerable amount of attention both in the long-established and in the recent literature. Because domain ...
  • BOSSERT, Walter; D'AMBROSIO, Conchita (2005)
    We introduce and axiomatize a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki’s index by multiplying it by a function that is interpreted as measuring the ...
  • BOSSERT, Walter; DERKS, Jean; PETERS, Hans (2001)
    A contingent contract in a transferable utility game under uncertainty specifies an outcome for each possible state. It is assumed that coalitions evaluate these contracts by considering the minimal possible excesses. A ...
  • BOSSERT, Walter; SPRUMONT, Yves (2002)
    We analyze collective choice procedures with respect to their rationalizability by means of profiles of individual preference orderings. A selection function is a generalization of a choice function where selected alternatives ...
  • BOSSERT, Walter; SPRUMONT, Yves (2013-01)
    A choice function is backwards-induction rationalizable if there exists a finite perfect-information extensive-form game such that, for each subset of alternatives, the backwards-induction outcome of the restriction of ...
  • Bossert, Walter; Suzumura, Kotaro (2014-05)
    We generalize the classical expected-utility criterion by weakening transitivity to Suzumura consistency. In the absence of full transitivity, reflexivity and completeness no longer follow as a consequence of the system ...
  • BOSSERT, Walter; QI, Chloe X.; WEYMARK, John A. (2012-07)
    Extensive social choice theory is used to study the problem of measuring group fitness in a two-level biological hierarchy. Both fixed and variable group size are considered. Axioms are identified that imply that the group ...
  • BOSSERT, Walter; D'AMBROSIO, Conchita; LA FERRARA, Eliana (Université de Montréal, Département de sciences économiques, 2008-01)
    The goal of this paper is to contribute to the economic literature on ethnic and cultural diversity by proposing a new index that is informationally richer and more flexible than the commonly used ‘ethno-linguistic ...
