Ecology-economic system of bioresource' exploitation with vector payoffs

Abstract

Discrete time game-theoretic model of ecology-economic system is considered. Agents (firms or fishermen's artels) which exploit the fish stock on a finite planning horizon are the participants of the game. Agents wish to achive several goals, hence the vector functions for players' payoffs are considered. The approaches to obtain optimal noncooperative and cooperative behavior in dynamic multicriteria games are constructed. To construct a multicriteria Nash equilibrium Nash bargaining construction (Nash product) is adopted, to find a multicriteria cooperative equilibrium Nash bargaining scheme for whole planning horizon is applied. The main goal of the paper is to construct the cooperative behavior of the participants and to apply the presented scheme for rational exploitation of Karelian bioresources.
