Agent-based Simulations for Examining Stability and Efficiency of Societies with Respect to Partnership Structures

In this paper, we deal with partnership among agents in an economic situation with different production skills and abilities where they are free to form coalitions, alliances or partnerships. And from the viewpoints of stability and efficiency we examine the resulting partnership structure. To take into account restrictions on partner selection, various production skills, and environmental changes, we employ an artificial social model in which such aspects can be incorporated in a relatively easy way, and perform the agent-based simulations for analyzing the partnership structure. From the experimental results, we find that the stability and the efficiency of the partnership structures depend on cost, production function, or number of agent types.
