This paper addresses a set of methodological problems arising in the empirical validation of agent-based (AB) economics models and discusses how these are currently being tackled. These problems are generic for all those engaged in AB modelling, not just economists. The discussion is therefore of direct relevance to JASSS readers. The paper has two(More)
The paper uses a two-stage, multi-agent simulation model to examine the conditions under which technological successions can occur in the presence of network externalities. Data is used to identify a robust econometric model of the probability of succession. Four key factors are identified. First, the trade-off between higher direct utility from new(More)
This paper addresses the methodological problems of empirical validation in agent-based (AB) economics models and how these are currently being tackled. We first identify a set of issues that are common to all modellers engaged in empirical validation. We then propose a novel taxonomy, which captures the relevant dimensions along which AB economics models(More)
Organisational innovation, information technology, and outsourcing to business services Abstract This paper examines the relationship between organisational innovation, the introduction of new internet-based ICTs, de-verticalisation, and the rapid growth in business service outsourcing over the last decade. In order to examine this issue, we develop a model(More)
This paper addresses the problem of finding the appropriate method for conducting empirical validation in agent-based (AB) models, which is often regarded as the Achilles' heel of the AB approach to economic modelling. The paper has two objectives. First, to identify key issues facing AB economists engaged in empirical validation. Second, to critically(More)
