We introduce a simple extension of a shifted geometric Brownian motion for modelling forward LIBOR rates under their canonical measures. The extension is based on a parameter uncertainty modelled through a random variable whose value is drawn at an in¯nitesimal time after zero. The shift in...

Generalized Lotka-Volterra (GLV) models extending the (70 year old) logistic equation to stochastic systems consisting of a multitude of competing auto-catalytic components lead to power distribution laws of the (100 year old) Pareto-Zipf type. In particular, when applied to economic systems,...

This paper presents a large-scale application of multi-agent, evolutionary modelling to the proposed new electricity trading arrangements (NETA) in the UK. This is a detailed, plant-by-plant model with an active specification of the demand side of the market. NETA involves a bilateral forwards...

This paper argues that a model in which consumers have accurate knowledge of their own idiosyncratic circumstances but `sticky expectations' about the macroeconomy can reconcile conflicting evidence about consumption dynamics from micro and macro data. Sluggish aggregate spending growth, which...

Computational laboratories (CLs) are computational frameworks that facilitate the study of complex system behaviors by means of controlled and replicable experiments. CLs permit students to engage in open-ended creative research, to explore interesting questions of their own devising for which...
