Description: The Joint Utility Function is a concept in game theory and economics that represents the preferences of multiple agents within a single framework. This function allows for the combination of individual utilities from different participants in a decision-making situation, thus facilitating the analysis of how a group’s decisions can affect all its members. The joint utility is used to evaluate collective well-being and is based on the premise that a group’s decisions should consider the preferences and needs of all its members. This function is particularly relevant in contexts where decisions are interdependent, such as in resource allocation, negotiation, and cooperation among agents. By integrating individual utilities, the aim is to find solutions that maximize overall well-being, thereby promoting efficiency and equity in resource distribution. The Joint Utility Function is fundamental for the development of optimization models that address complex problems involving multiple actors, allowing for a better understanding of social and economic dynamics.
