The model of the labor market naturally describes only a part of an economic system - the one which was idealized in the models in Volume 1 [4] via the aggregation of all working forces. As the simulation of fluctuating working forces has worked so well with my model it is a tempting task to integrate the labor market model with the models of national economies. Since this task, including the sub-problems that are still to be expected, means a greater effort, I have to postpone it. But I can't help but at least take the first step and then briefly discuss some expected problems.
