Abstract
Concern has been expressed in some quarters about the ability of Agent-Based Modelling to progress rather than merely proliferate arbitrary models. This chapter offers a case study of an elderly Agent-Based Model (hereafter ABM) being resurrected because it seemed suitable to a new use, namely to study the effect of the current UK economic crisis on health and wellbeing. The chapter aims to contribute on two levels. One is to discuss the resurrection of the ABM, replicate its original results (enhanced with explanations) and extend it to the new situation. This is very much research in progress. The other aim is to show how, to be progressive, ABMs need to remain in use and effectively accessible to the research community. The present case study shows how published ABMs alone are unlikely to satisfy that requirement as time passes (and thus facilitate progressive research). Because this is work in progress, it also attempts to show how some modelling commonplaces (for example that arbitrary models still enhance understanding) work in practice. Such aspects are often written out when publishing research that is considered finished.
