We provide several new characterizations of well known cost sharing methods (CSMs) as maxima of linear (or convex) functionals. For the Shapley-Shubik method the characterization has an interpretation in terms of randomly ordered agents choosing their most preferred CSM, while the...

Communication has been regarded as one of the most effective devices in promoting team cooperation. But asymmetric communication sometimes breeds collusion and is detrimental to team efficiency. Here, we present experimental evidence showing that excluding one member from team communication...

In this paper we study consistency in the context of additive cost sharing mechanisms. We contrast an extremely weak notion of consistency with the standard definition, which we denote strong consistency. First we show that many well known CSMs are consistent in both senses: Aumann-Shapley,...
