Abstract

We introduce participation uncertainty to the theory of cooperative TUgames. Under participation uncertainty, each coalition’s effective value is an expected value taken over the (full) value of its subsets. We identify ‘constant-marginal’ participation as a key property for various economic problems to be well-behaved. This class of uncertainty environments is closed for mixing and composition. Under this property, solution concepts are easily calculate, two-sided markets clear and are insurable, and voting power under uncertain participation can be characterized and efficiently computed.
