Noncooperative Foundations of the Area Monotonic Solution

Given a finite set of alternatives, players alternate making offers. Player 1 offers some alternative that 2 can accept or veto. If 2 accepts, it is enforced, and the game ends. Otherwise, 2 makes a counteroffer among the remaining alternatives, and so on. If all alternatives are vetoed, a disagreement alternative is enforced. First, we characterize the unique outcome of any subgame perfect equilibrium of this game. Then, we show that this outcome converges to the Area Monotonie Solution if the alternatives are uniformly distributed over the bargaining set, and as the number of alternatives tends to infinity.
