Theoretical Foundations for the Rotterdam Model.

A now widespread critique of the Rotterdam Model correctly observes that the model's properties and theoretical implications are known exactly only in a highly restrictive and uninteresting special case. Hence the model currently can be related exactly to available theory only if that unacceptably restrictive special case is maintained. In this paper, we shall fill the gap in our knowledge which has been observed to exist by the model's critics. We shall derive the model's theoretical properties at the aggregate level over a much larger region of the macroparameter space than the tiny region within which the currently understood special case is defined.
