Robustness assessment of the ‘cooperation under resource pressure’ (CURP) model: Insights on resource availability and sharing practices among hunter-gatherers Zurro, Débora Ahedo García, Virginia Pereda, María Álvarez, Myrian Briz i Godino, Ivan Caro Saiz, Jorge Santos Martín, José Ignacio Galán Ordax, José Manuel Hunter-gatherers Agent-based model ABM Cooperation under resource pressure CURP Resource availability Reciprocity Robustness assessment A well-known challenge in archaeological research is the exploration of the social mechanisms that hunter-gatherers may have implemented throughout history to deal with changes in resource availability. The agent-based model (ABM) ‘cooperation under resource pressure’ (CURP) was conceived to explore food stress episodes in societies lacking a food preservation technology. It was particularly aimed at understanding how cooperative behaviours in the form of food sharing practices emerge, increase and may become the prevailing strategy in relation to changes in resource availability and expectancy of reciprocity. CURP’s main outcome is the identification of three regimes of behaviour depending on the stress level. In this work, the model’s robustness to the original selection mechanism (random tournament) is assessed, as different dynamics can lead to different persistent regimes. For that purpose, three other selection mechanisms are implemented and evaluated, to identify the prevailing states of the system. Results show that the three regimes are robust irrespective of the analysed dynamics. We consequently examine in more detail the long-term archaeological implications that these results may have. 2022-01-25T13:15:55Z 2022-01-25T13:15:55Z 2022-01-25T13:15:55Z 2017-04 info:eu-repo/semantics/article 2056-3264 http://hdl.handle.net/10259/6359 10.3828/hgr.2017.20 2056-3264 eng Hunter Gatherer Research. 2017, V. 3, n. 3, p. 401–428 https://doi.org/10.3828/hgr.2017.20 info:eu-repo/grantAgreement/MICINN/Plan Estatal de Investigación Científica y Técnica y de Innovación 2008-2011/CSD2010-00034/ES/Social and environmental transitions: simulating the past to understand human behaviour info:eu-repo/grantAgreement/EC/H2020/662725/EU/Bridging the gap: from Individual Behaviour to the Socio-tEchnical MaN info:eu-repo/grantAgreement/MICINN//HAR2009-06996/ES/Marcadores Arqueologicos De Relaciones Sociales: Etnoarqueologia De Cazadores-Recolectores En El Canal Beagle info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/HAR2016-77672-P/ES/MODELADO DEL CULTIVO EN LA PREHISTORIA info:eu-repo/grantAgreement/CONICET//PIP-0706/AR/ info:eu-repo/grantAgreement/Wenner-Gren Foundation//GR7846 info:eu-repo/semantics/openAccess Liverpool University Press
