Background: ▪ Well-known measures of resilience based on ecosystems modelling. ▪ Some socio-economic conceptualisations but few decision-theoretic formulations to date. Objectives: ▪ To set out a (simple) model of renewable resource use and conceptualise resilience in a rigorous decision-theoretic way. ▪ To derive a model-based measure of resilience and apply it to assess resilience of resource use.
