Bargaining is a research area within game theory that focuses on the strategic interactions between individuals or groups who have conflicting interests and need to reach a mutually acceptable agreement. The goal of bargaining is to divide a set of resources or benefits among the parties involved in a way that maximizes their own outcomes while considering the preferences and constraints of the other parties. This research area explores different bargaining strategies, negotiation tactics, and mechanisms for reaching agreements, such as haggling, ultimatums, and cooperative bargaining. Some common models used in bargaining research include the Nash bargaining solution and the Rubinstein bargaining model.
