= Negotiation set
{synonym}

For a <compact convex set> of feasible <payoff> <vectors> $F$ and a specified <disagreement point> $d$, the <negotiation set> is its individually rational <Pareto frontier>. It is the set of efficient agreements each player prefers at least weakly to disagreement. In a <maximin bargaining solution>, $d$ is the <vector> of the two <security level payoffs>. This usage is distinct from objection-and-counterobjection bargaining sets in coalitional-game theory.
