Informational geometry of social choice
Elementary geometry is used to understand, extend and resolve basic informational difficulties in choice theory. This includes axiomatic conclusions...

Market arbitrage, social choice and the core
This paper establishes a clear connection between equilibrium theory, game theory and social choice theory by showing that, for a well defined...

Competitive lobbying for a legislator’s vote: A comment
This comment deals with some imperfections of the analysis presented by Austen-Smith and Wright [1]. It is argued that in [1] being informed is...

Social choice with infinite populations: construction of a rule and impossibility results
We provide a simple construction of social choice rules for economies with infinite populations. The rules are continuous, Pareto and...

Continuity and equity with infinite horizons
In an infinite dimensional space, e.g. the set of infinite utility streams, there is no natural topology and the content of continuity is...

Strategy-proofness on Euclidean spaces
In this paper we characterize strategy-proof voting schemes on Euclidean spaces. A voting scheme is strategy-proof whenever it is optimal for every...

Topological aggregation, the case of an infinite population
The literature on infinite Chichilnisky rules considers two forms of anonymity: a weak and a strong. This note introduces a third form: bounded...

Equitable agendas: agendas ensuring identical sincere and sophisticated voting decisions
Sophisticated voting under amendment procedure using majority rule usually results in a decision that is distinct from the decision obtained through...

Election of vice-president and adding new members to representative bodies
In Tanguiane (1991, 1993, 1994) we have introduced quantitative indicators of representativeness, with which we have estimated the capacity of...

Acyclic sets of linear orders
A set of linear orders on {1,2, ℕ, n } is acyclic if no three of its orders have an embedded permutation 3-cycle { abc, cab, bca }. Let f ( n ) be the...

Outranking methods for multicriterion decision making: Arrow’s and Raynaud’s conjecture
Outranking methods constitute a class of ordinal ranking algorithms for multicriterion decision making. This paper is concerned with four such...

Equitable opportunities in economic environments
In this paper, we extend the axiomatic analysis of equitable opportunities developed in Kranich [6] from finite to continuous opportunity sets. This...

Strategy-proofness versus efficiency on restricted domains of exchange economies
Strategy-proofness has been shown to be a strong property, particularly on large domains of preferences. We therefore examine the existence of strategy-proof...

Reference functions and possibility theorems for cardinal social choice problems
In this paper, we provide axiomatic foundations for social choice rules on a domain of convex and comprehensive social choice problems when agents...

Utilities, preferences, and substantive goods
People’s utility levels are meant to be measures of their well-being . Early utilitarians defined them in terms of people’s happiness. Modern...

Modelling the inflation process in transition economies: Empirical comparison of Poland, Hungary and Czech Republic
This paper starts from the observation that inflation in transition economies appears to be persistently high and volatile and attempts to provide...

Education
Of all the subjects on which statistical material exists, probably none shows less uniformity, both over time and between countries, than education....

The Lucas Critique in Practice
Lucas (1976, p. 41) proposes an explanation for why coefficients in econometric equations might be nonconstant when policy rules change: “[G]iven...

An empirical test of ordinal independence
In this article, we test Green and Jullien's (1988) Ordinal Independence (OI) Axiom, an axiom necessary for any rank-dependent expected utility...
