a.k.a. Nash Equilibrium.  In reality of course, the bar scene from Ron Howard’s film, “A Beautiful Mind” is not how the real Nobel Prize recipient for Economics John Forbes Nash Jr. came upon the idea.  Economics is a system for optimizing resources, which is one of several approaches Pactum Factum applies to negotiation and mediation. In a Nash equilibrium, each party’s strategy is optimal when considering the decisions of other parties. Every party wins because everyone gets an outcome they desire, even if it isn’t their preferred outcome individually. A Nash equilibrium teaches us that decisions that are good for individuals can sometimes be terrible for groups. A cooperative strategy is one that leads to the highest joint payoff for all participants.
