Bargaining may have to concern itself with an “incentive” system as well as the division of gains. Oligopolists may lobby for a “fair-trade” law; or exchange shares of stocks. An agreement to stay out of each other’s market may require an agreement to redesign the products to be unsuitable in each other’s area. Two countries that wish to agree not to make military use of an island may have to destroy the usefulness of the island itself. (In effect, a “third-party commitment” has to be assumed when an effective “second-party commitment” cannot be devised.)

XREF: This connects to commitment and threat-credibility themes in bargaining theory, likely from Schelling's work on strategy.
