Improving agent-based models of diffusion

Purpose This paper aims to review the validation of assumptions made in agent-based modeling of diffusion and the sufficiency (completeness) of the mechanisms assumed to operate. Design/methodology/approach One well-cited paper is examined. Findings Evidence is presented that casts doubt on the assumptions and mechanisms used. A range of mechanisms is suggested that should be evaluated for inclusion in diffusion modeling. Originality/value The need for validation of assumptions has been stressed elsewhere but there has been a lack of examples. This paper provides examples. The stress on the sufficiency of the mechanisms used is new.
