ALTRUISTIC BEHAVIOR IN GAME-THEORETIC ENVIRONMENTAL MODELS
We consider a game-theoretic environmental model described by a differential game with an infinite horizon. The traditional approach is that players are rational and use selfish behavior that maximizes their personal winnings. But the selfish behavior of the players can have a negative impact on the environment. The reason is the limited supply of resources, which is influenced by all players (the tragedy of communs). We propose the concept of altruistic equilibrium in a differential game related to environmental issues and compare them with the Nash equilibrium. We assume that the players are connected by some network structure. According to the concept of altruistic equilibrium, players can offset a portion of other players’ related payoffts with a portion of their own profits. We conduct numerical simulations and demonstrate the effectiveness of this approach in solving problems related to the use of natural resources related to the exploitation of natural resources.
