 A more empirically minded approach follows Schelling’s (1960) early work on bargaining and game theory by looking at the way actual people bargain and reach agreement. The pioneers of experimental economics used laboratory experiments to look at how subjects behaved in division problems (Hoffman et. al. 2000, Smith 2003). Some of the most interesting results came, perhaps surprisingly, from asymmetric bargaining games like the ultimatum game (Smith 1982). Since these early experiments, considerable experimental work has been done on bargaining problems and cooperative agreement in economics. Much of the most philosophically relevant work involves the importance of social norms and conventions in determining the result (Bicchieri 2016, Vanderschraaf 2018).
