An epistemic utility approach to coordination in the Prisoner's Dilemma

A probabilistic model of single-agent decision making is reviewed which accounts for considerations of both correctness and value. The formalism is then extended to decisions involving multiple agents by the use of a joint coordination function. individual agents are characterized by factoring the coordination function in terms of conditional valuation and belief functions. This formalism is used to explore the parameter space in which cooperative decisions are possible in the Prisoner's Dilemma.
