Metric rationalization of bargaining solutions
(2010-03-28)
In this paper we represent bargaining solutions by means of a metric which is defined on games, whereby the solutions are precisely those payoffs which are closest to being unanimously highest.
Mid-point domination and a solution to choice problems on non-convex domains
(2010-03-31)
In this paper we axiomatically characterize a solution to choice problems on non-convex domains, which satisfies mid-point domination and other intuitively reasonable properties.
Dynamic optimization with integral state equations
(2010-03-21)
In this paper we obtain necessary and sufficient conditions for optimality in dynamic optimization problems governed by integral state equations.
Axiomatic analysis of vote aggregators
(2010-01-16)
In this paper a model for the aggregation of ballot profiles is considered. In this framework some new results are obtained: the characterization of oligarchic aggregators, the characterization of the plurality aggregator ...
Axiomatic characterization of indirect utility and lexicographic extensions
(2010-01-16)
The general problem we are interested in this paper is of the following variety: We are given a finite universal set and a linear ordering on it. What is the minimal axiomatic characterization of particular extension of ...
Justifiable preferences for freedom of choice
(2010-01-16)
In this paper we say that a preference for freedom of choice is justifiable if there exists a reflexive and complete binary relation on the set of alternatives, such that one oppurtunity is atleast as good as a second, if ...
Problems of fair division and the egalitarian solution: a reconsideration
(2010-01-16)
The present paper attempts to provide simple proofs of two theorems in the literature of axiomatic bargaining with a variable population. Both theorems deal with axiomatic characterizations of the egalitarian solution due ...
Threshold of median rank solutions
(2010-01-18)
In this paper we consider solutions defined on the class of transitive tournaments. Such solutions are essentially rank solutions i.e. solutions which depend on the ranks of the alternatives and not on any other physical ...
Quasitransitivity and monotonic preference for freedom
(2010-01-16)
We consider a finite universal set of alternatives and the set of all feasible sets are simply the set of all non-empty subsets of this universal set. A choice function assigns to each feasible set a non-empty subset of ...
Weighted fair division problem
(2010-01-18)
The exact problem we are concerned with in this paper is of the following nature. There are a finite number of producers each equipped with a utility function of the standard variety, which converts and input into a producer ...
