In A recent paper Rubinstein, Safra, and Thomson2 (hereafter, RST) have provided ?. interesting re-examination of the widely applied Nash solution for a two-person bargain-ing problem. They recast the usual Nash bargaining problem into a more "natural" setting ot feasible alternatives with a disagreement outcome. The two players are then described by their risk preferences denned on the set of lotteries over the alternatives and me disagreement outcome. This enables them to define an ordinal Nash solution in terms of the agents' risk preferences. Essentially their ordinal solution is an outcome that is immune" against possible objections.
