“…Once the product is established on the market, increased demand from other applications might restrict the availability of marginal elements such as REEs and PGMs. Such potential supply restriction can be seen as an emergent property of interacting agents across the supply-demand network, which can be captured with agent-based modelling (ABM) (Axelrod, 1997;Janssen, 2002;Tesfatsion and Judd, 2006). ABM as a bottom-up approach is commonly used for analysing transition dynamics in socio-technical systems Chappin and Dijkema, 2010;.…”

Abstract:Emerging technologies such as information and communication-, photovoltaic-or battery technologies are expected to increase significantly the demand for scarce metals in the near future. The recently developed methods to evaluate the criticality of mineral raw materials typically provide a 'snapshot' of the criticality of a certain material at one point in time by using static indicators both for supply risk and for the impacts of supply restrictions. While allowing for insights into the mechanisms behind the criticality of raw materials, these methods cannot account for dynamic changes in products and/or activities over time. In this paper we propose a conceptual framework intended to overcome these limitations by including the dynamic interactions between different possible demand and supply configurations. The framework integrates an agent-based behaviour model, where demand emerges from individual agent decisions and interaction, into a dynamic material flow model, representing the materials' stocks and flows. Within the framework, the environmental implications of substitution decisions are evaluated by applying life-cycle assessment methodology. The approach makes a first step towards a dynamic criticality assessment and will enhance the understanding of industrial substitution decisions and environmental implications related to critical metals. We discuss the potential and limitation of such an approach in contrast to state-of-the-art methods and how it might lead to criticality assessments tailored to the specific circumstances of single industrial sectors or individual companies.

“…However, if the game is iterated and "the shadow of the future" is long enough, there will be an incentive for two actors to disarm. The peaceful strategy may spread in a population and become evolutionarily stable (Axelrod 1984(Axelrod , 1997.…”

The Kula Ring of Bronislaw Malinowski: Co-evolution of an Economic and Ceremonial Exchange System

The Kula Ring described by Bronislaw Malinowski is a system of the ceremonial exchange of gifts among a number of tribal societies inhabiting various island groups in the region east of Papua New Guinea. Two ceremonial gifts continually circulate in opposite directions: necklaces clockwise and armshells counterclockwise. After a brief description of the social system of Kula exchange, a game-theoretic interpretation of the ceremonial exchange as a signaling system for peaceful relationships, with inbuilt checks against cheating, is given. A simulation model of the starting mechanism is presented to account for the emergence and stability of the observed pattern of circular exchange of the two ceremonial gifts. Three processes are distinguished: the development of an economic trading network, the spread of peaceful relationships and the evolution of a ceremonial exchange network of Kula valuables. These processes are systematically linked to model the spontaneous emergence and co-evolution of the Kula Ring.

“…A impossibilidade de se testar hipóteses relativas a eventos ocorridos no passado sempre foi um problema para a arqueologia, mas avanços tecnológicos recentes viabilizaram alternativas metodológicas através da construção de modelos computacionais, que permitem simular dinâmicas socioambientais (Axelrod, 1997). Esses modelos já possibilitaram importantes avanços em outras áreas como na sociologia, antropologia, economia e biologia (Axelrod, 1997;Helbing & Balietti, 2012;Janssen, 2005;Terano, 2011;Wallick, 2012). Modelos computacionais permitem construir cenários hipotéticos tendo como base teorias propostas na literatura, utilizando dados primários e secundários, tornando possível realizar testes de hipóteses relativas a períodos pré-históricos (Bowles & Choi, 2013;Freeman et al, 2015;Gallagher, Shennan & Thomas, 2015).…”

“…Trata-se de um conjunto de técnicas computacionais que simulam agentes heterogêneos e comportamentos adaptativos (Wallick, 2012), cujo propósito é compreender as propriedades envolvidas em sistemas adaptativos complexos, através da simulação (Axelrod, 1997). Conforme Terano (2011), com esses modelos é possível tornar as ciências sociais operacionais, comunicáveis e experimentais.…”
