Thanks B for yet another interesting article.

What I wonder is if certain models, such as the diminishing ore quality in Simon Michaux's work or population growth models, could be plugged into a set of differential equations to get an idea of the economic development. Then, if one chose a premise of a say 2.5% economic growth per annum, what would be the effect? Alternatively, if one put other constraints in place such as available resources and energy, what could be the achievable economic growth, if any at all? Do you know about some dynamic economic modelling?
