Like the Nash solution to the cooperative bargaining problem, several alternative solutions suggested by Raiffa in the early 1950's were originally proposed for the two-person case. All of these solutions have a number of appealing properties, and all of them have been extended for the case of more than two persons.
We discuss several modifications and generalizations of the discrete Raiffa solution for a number of domains of the n-person case. Moreover, we present some open problems concerning axiomatic characterization.
