Axiomatic characterization of the lexicographic utilitarian collective utility function
(2010-03-29)
In this paper we axiomatically characterize the family of lexicographic utilitarian collective utility functions. As a by-product we obtain the utilitarian collective utility function by imposing a shift anonymity condition. ...
Logarithmic relative egalitarian solution: an axiomatic characterization
(2010-03-27)
In this paper we propose and axiomatically characterize the Logarithemic Relative Egalitarian Solution for social choice problems.
On a theorem due to sobel
(2010-03-27)
In this paper we prove that any bargaining solution to group decision problems which satisfies individual rationality, strong symmetry, efficiency and strong improvement sensitivity also satisfies mid-point domination.
Note on a reduced game property for the egalitarian solution
(2010-03-27)
In this paper we obtain an axiomatixation of the egalitarian solution using a reduced game property.
Shifts in multiattribute choice problems
(2010-03-27)
In this paper we study the responsiveness of choice functions to shifts in multiattribute choice problems.
Restricted Expansion Independence for Choice Problems
(2010-03-27)
In this paper we propose restricted expansion independence as a criterion which may be satisfied by desirable choice functions and axiomatically characterize the proportional solution by using this criterion. We also show ...
On the existence and efficiency of a voting equilibrium for a public good economy
(2010-03-27)
The main purpose of this paper is to formalise the concept of a compromise function. Subsequently, given a compromise function, we define a voting equilibrium and prove the existence of such an equilibrium. Finally, we ...
Sharing costs and sharing revenue: the proportional solutions
(2010-07-27)
Consider a group of people who have just been awarded a sum of money to undertake a consultancy for a research project. The problem that now confronts them is to share the revenue as well as the costs of the overheads ...
Reduced game property for the egalitarian solution
(2010-07-27)
In this paper we obtain an axiomatization of the egalitarian solution using a reduced game property.
Rationing and the private provision of a public good
(2010-07-27)
In this paper we study a solution concept for resource allocation in an economy with public goods and a fixed set of cost-shares for each agent. This solution is originally due to Champsaur (1979). We study the existence ...
