Explanatory Macroeconomic Dynamics; Relevant In Any Instance

There are five figures below from CWL 15:  The single figure on the left represents the interrelations of interdependent Monetary Flows; and the figure contains the important condition of dynamic equilibrium: G = c”O” -i’O’ = 0.  The four figures stacked on the right demonstrate aspects of the productive phases constituting a Pure Cycle of Expansion. The bidirectional arrows uniting the two sides signify that the dynamic equilibrium among interdependent flows specified on the left is to be achieved consistently throughout the long-run expansion represented on the right.  This condition of dynamic equilibrium is that the crossover flows between the two interacting circuits must continuously balance even as they continuously vary in magnitude in the succession of phases constituting the expansionary process.  Just as the general laws of simple parabolic or pendular motion are explanatory and applicable to any particular instance of initial angle and velocity, so a) the primary relativities of productive and monetary flows, and b) the primary differentials of long-term expansion explain the economic process, and are normatively relevant in every particular instance.  All five diagrams are unitary.  Each and every velocitous and accelerative flow of products and money has proximate or remote explanatory aspects embedded in all five diagrams.
