Special Case

An agent- based model of social dynamics is introduced using a deformable fitness landscape, and it is shown that in certain clearly specifiable situations, strategies that are different from utility maximization outperform utility maximizers. Simulation results are presented and intuitive interpretations of the results provided. The situations considered occur when individuals' actions affect the outcomes for other agents and endogenous effects are dominant. The Tragedy of the Commons is merely a special case of this. Arguments are given that constraints are to be encouraged in some circumstances. The appropriate role of constraints in various types of society is assessed and their use justified in identifiable types of situations.

Over Time

Electronic communication allows interactions to take place over great distances. We build an agent-based model to explore whether networks that do not rely on geographic proximity can support cooperation as well as local interactions can. Adaptive agents play a four-move Prisoner's Dilemma game, where an agent's strategy specifies the probability of cooperating on the first move, and the probability of cooperating contingent on the partner's previous choice. After playing with four others, an agent adjusts its strategy so that more successful strategies are better represented in the succeeding round. The surprising result is that if the pattern of interactions is selected at random, but is persistent over time, cooperation emerges just as strongly as it does when interactions are geographically local. This has implications for both research on social dynamics, and for the prospects for building social capital in the modern age.

Comparison Of The Results

Abstract Background and Purpose: The purpose of this study is to describe the principles of the development of parallel system-dynamics and agent-based models of organic farming for the case of Slovenia. The advantage of agent-based modeling is demonstrated by including geospatial information as an agent attribute. The models were compared by the validation, confirming the appropriate level of similarity. Design/Methodology/Approach: Both system-dynamics and agent-based modeling approaches were applied. Statistical methods were used in the validation. Results: The results of the validation confirm the appropriateness of the proposed agent-based model. Introducing additional attributes into the agent-based model provides an important advantage over the system-dynamics model, which serves as the paradigmatic example. Conclusion: A thorough validation and comparison of the results of the system-dynamics and agent-based models indicates the proper approach to combining the methodologies. This approach is promising, because it enables the modeling of the entire agricultural sector, taking each particular farm into account.
