Expected utility without full transitivity

Walter Bossert, Kotaro Suzumura
2015 Social Choice and Welfare  
We generalize the classical expected-utility criterion by weakening transitivity to Suzumura consistency.  ...  This class is characterized by means of standard expected-utility axioms in addition to Suzumura consistency.  ...  Details on this alternative result are available from the authors on request. The remaining axiom is Suzumura consistency.  ...

Product filters, acyclicity and Suzumura consistency

Walter Bossert, Kotaro Suzumura
2012 Mathematical Social Sciences  
We examine the notion of decisiveness with acyclical or Suzumura consistent social preferences and without assuming that the social relation is complete.  ...  In a seminal contribution, Hansson (1976) demonstrates that the collection of decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter.  ...  In this paper, we consider an environment where social preferences are assumed to satisfy alternative weakenings of transitivity, namely, acyclicity or Suzumura consistency.  ...

Revealed preference and choice under uncertainty

Walter Bossert, Kotaro Suzumura
2011 SERIEs: Journal of the Spanish Economic Association  
In addition to rationalizability per se, we characterize transitive and Suzumura consistent rationalizability in the presence of dominance.  ...  Rather than focusing on a specific theory of choice, our objective is to formulate a general approach that is designed to cover the various decision criteria that have been proposed in the literature.  ...  This is an immediate consequence of the observation that Suzumura consistency and transitivity coincide in the presence of reflexivity and completeness; see Suzumura (1976b) .  ...

An Interview with Kotaro Suzumura

Walter Bossert, Marc Fleurbaey
2014 Social Choice and Welfare  
How and when did you develop an interest in these topics?  ...  It was an extreme example of non-standard education in these days. I was then a third year undergraduate.  ...  It did not take long before I formulated a new concept of consistency, viz., Suzumura- consistency A t-tuple of alternatives (x 1 , x 2 , . . . , x t ) in X is an S-cycle of order t if and only if (x  ...

A Note on Incompleteness, Transitivity and Suzumura Consistency [chapter]

Richard Bradley
2015 Studies in Choice and Welfare  
Suzumura consistency of preferences is shown to be both necessary and su¢ cient for non-empty strongly maximal choice.  ...  Nor therefore that they be transitive: Suzumura consistency su¢ ces. This paper examines the implications of these claims for the theory of rational choice.  ...  both Suzumura consistent and complete is strongly consistent.  ...

Rationality, external norms, and the epistemic value of menus

Walter Bossert, Kotaro Suzumura
2011 Social Choice and Welfare  
Ever since Sen's (1993; 1997) criticism on the notion of internal consistency or menu independence of choice, there exists a widespread perception that the standard revealed preference approach to the  ...  Gaertner and Xu (1999a) discuss an alternative approach covering cases where external norms may lead to the choice of the median alternative(s) according to some antisymmetric relation on X.  ...  See Bossert and Suzumura (2008) for a detailed discussion of rationalizability with alternative coherence requirements on the rationalizing relation, such as quasi-transitivity, acyclicity and consistency  ...

EXTERNAL NORMS AND RATIONALITY OF CHOICE

Walter Bossert, Kotaro Suzumura
2009 Economics and Philosophy  
Ever since Sen (1993) criticized the notion of internal consistency of choice, there exists a widespread perception that the standard rationalizability approach to the theory of choice has difficulties  ...  We are grateful to Bhaskar Dutta, Prasanta Pattanaik, Donald Saari, Thomas Schwartz as well as an editor and two referees of this Journal for their helpful comments.  ...  As shown by Suzumura (1976b) , consistency is necessary and sufficient for the existence of an ordering extension; see Suzumura (1976b, pp.389-390) .  ...

A Representation of the Maximal Set in Choice Problems Where Information Is Incomplete

Andrikopoulos Athanasios
2018 Theoretical Economics Letters  
Suzumura and Xu [2] extended Banerjee and Pattanaik's result by relaxing the axiom of transitivity to the axiom that Suzumura calls consistency.  ...  Arló Costa in [3] pointed out that in general, an optimizing model cannot require the transitivity of the binary relation used in an optimizing model.  ...  Suzumura and Xu [2] extended Banerjee and Pattanaik's result by relaxing the axiom of transitivity to the axiom that Suzumura calls consistency [6] .

Multi-Profile Intertemporal Social Choice: A Survey [chapter]

Walter Bossert, Kotaro Suzumura
2015 Studies in Choice and Welfare  
We review contributions that explore whether this possibility in the infinite-population context allows for a richer class of social welfare functions in an intergenerational model.  ...  Packel The second approach involves replacing classical stationarity with a multi-profile variant of stationarity and an alternative domain restriction due to Bossert and Suzumura (2011) .  ...  Packel's (1980) approach consists of restricting the domain of a social welfare function to profiles where the individual preferences (or generation one's preferences) are themselves stationary.  ...

A variant of non-consequentialism and its characterization

Yukinori Iwata
2007 Mathematical Social Sciences  
This paper presents an axiomatic characterization of a nonconsequentialist extended preference whose opportunity evaluation is based on the leximax ordering.  ...  Acknowledgements We are grateful to Kotaro Suzumura and Naoki Yoshihara for their helpful suggestions and encouragement.  ...  An approach to this issue is to make a lexicographic comparison between two criteria.  ...

Existence of Order-Preserving Functions for Nontotal Fuzzy Preference Relations under Decisiveness

Paolo Bevilacqua, Gianni Bosi, Magalì Zuanon
2017 Axioms  
We further present conditions for the existence of an upper semicontinuous order-preserving function for a fuzzy binary relation on a crisp topological space.  ...  Looking at decisiveness as crucial, we discuss the existence of an order-preserving function for the nontotal crisp preference relation naturally associated to a nontotal fuzzy preference relation.  ...  By contraposition, assume that is not Suzumura consistent.  ...

Are most people consequentialists?

Olof Johansson-Stenman
2012 Economics Letters  
Overall, people's perceptions are largely consistent with consequentialism.  ...  Suzumura (1999) and Suzumura and Xu (2001 , 2003 .  ...  Table 1 around here As seen in Table 1 , the result is quite consistent with the consequentialist ethics underlying conventional economic welfare theory, since almost two-thirds chose this alternative  ...

書評

Wulf Gaertner
1985 The Economic Studies Quarterly  
The author takes great pains to characterize all these approaches in terms of choice-consistency properties.  ...  Chapter 5 focuses on the fairness-as-no-envy approach. Fairness concepts proposed by Foley, Feldman, Kirman, Pazner, and others are examined in the light of choice-consistency requirements.  ...

On Non-Welfarist Social Ordering Functions [chapter]

Naoki Yoshihara
2008 Studies in Choice and Welfare  
For instance, let us take the Kaldor principle, which declares an alternative x to be superior to an alternative y if and only if there is another alternative z which is reached through redistribution  ...  Such an approach is one way to expand the limited informational basis of conventional welfarist's welfare economics.  ...  Note that for any z u , z Define an ordering R 0 e,J over Z(s) as follows: for any z, z 0 ∈ Z(s), Denote the set of maximal elements over Z(s) in terms of R 0 e,J by B ¢ .  ...

Compatible extensions and consistent closures: a fuzzy approach [article]

Irina Georgescu
2017 arXiv   pre-print
Two notions of consistent closure of a fuzzy relation are introduced.  ...  From this general result are obtained as particular cases fuzzy versions of some important extension theorems for crisp relations (Szpilrajn, Hansson, Suzumura).  ...  An agent chooses between different alternatives; the rationality of the act of choice is defined by a preference relation acting on the alternatives.  ...
