This paper will explore the effects of errors in floating point arithmetic in two published agent-based models: the first a model of land use change (Polhill et al. 2001; Gotts et al. 2003), the second a model of the stock market (LeBaron et al. 1999). The first example demonstrates how branching...

Agent-based models, perhaps more than other models, feature large numbers of parameters and potentially generate vast quantities of results data. This paper shows through the FEARLUS-G project (an ESRC e-Social Science Initiative Pilot Demonstrator Project) how deploying an agent-based model on...

This paper summarises some previously published work on imitation, experimentation (or innovation) and aspiration thresholds using the FEARLUS modelling system and reports new work with FEARLUS extending these studies. Results are discussed in the context of existing literature on imitation and...

In this paper social dilemmas are modelled as n-player games. Orthodox game theorists have been able to provide several concepts that narrow the set of expected outcomes in these models. However, in their search for a reduced set of solutions, they had to pay a very high price: they had to make...

We report on replications of early experiments with FEARLUS, using larger numbers of agents, larger numbers of land parcels, and greater network connectivity than in the original work. We find that results from the larger-scale experiments differ from the smaller environments used previously....

This study analyses the impact of a priori identified determinants of adoption of innovative animal health and welfare technologies by Scottish livestock farmers. The analysis uses a dataset of 1,764 observations for livestock farmers collected through a large scale survey of Scottish...

This paper addresses the question of farmer objectives associated with private farming in Eastern Europe. Drawing on qualitative interviews with private farmers in Bulgaria and southern Russia, the instrumental objectives of business development and job-replacement consistent with recent...
