We describe a new complex system model of an evolving production economy. This model is the simplest we can envisage which incorporates the new observation that the rate of an economic production process depends only on the minimum of its supplies of inputs. We describe how this condition gives rise to a new type of complex multiple timescale dynamical evolution through a novel type of bifurcation we call a `trapping bifurcation', which is also shown to be one cause of non-equilibrium economic b...
