Each agent in a finite set requests an integer quantity of an idiosyncratic good; the resulting total cost must be shared among the participating agents. The Aumann-Shapley prices are given by the Shapley value of the game where each unit of each good is regarded as a distinct player. The...

We study fairness in economies with one private good and one partially excludable nonrival good. A social ordering function determines for each profile of preferences an ordering of all conceivable allocations. We propose the following Free Lunch Aversion condition: if the private good...

We offer an axiomatization of the serial cost-sharing method of Friedman and Moulin (1999). The key property in our axiom system is Group Demand Monotonicity, asking that when a group of agents raise their demands, not all of them should pay less. Copyright 2010 The Econometric Society.

This paper considers the problem of social evaluation in a model where population size, individual lifetime utilities, lengths of life, and birth dates vary across states. In an intertemporal framework, the authors investigate principles for social evaluation that allow history to matter to some...

This paper introduces and characterizes a new class of solutions to cooperative bargaining problems that can be rationalized by generalized Gini orderings defined on the agents' utility gains. Generalized Ginis are orderings that can be represented by quasi-concave, nondecreasing functions that...
