The record price development in commodity markets during the economic boom period lasting from early 2000 to mid 2008 highlighted a perceived scarcity particularly in metal markets that contrasted the preceding period beginning in the late 1970s of largely abundant availability and falling real...

A methodology is offered which can be used to construct an econometric model in the presence of structural change of an evolutionary type. The theoretical basis for such modelling is drawn from the self-organisation approach and operationalised in the context of the logistic diffusion growth...
