Multiplayer Bargaining Situations : A Decision Theoretic Approach

The problem of ex ante choice between conflict situations is studied in an axiomatic model where individuals know the available surplus but are ignorant of the exact bargaining procedure. Furthermore, allowing for side-payments in a single good, a bargaining solution that is immune to ordinal transformations of players' preferences for the underlying set of alternatives is constructed. This solution requires that each player receive a weighted average of his marginal contribution to various coalitions. In fact, these weights coincide with the Shapley weights
