D1 Production and installed capacity

Topic

The gap between installed capacity and effective demand—the very same gap that triggers the shift from one mode to another within the Production component—is the central element organizing the four indicators in this block. When installed capacity utilization approaches its maximum, this gap pushes the Production track toward expansion; when utilization moves away from the maximum, the same gap pushes it toward contraction; and when effective demand falls steadily while production continues, inventories accumulate as a direct symptom of that gap between capacity and demand.

The industrial production index measures the physical volume of goods produced during a given period. A sustained decline in this index, accompanied by rising inventories, foreshadows a phase of structural overcapacity: when the industrial production index falls while inventories continue to build up, the gap between installed capacity and effective demand is already widening.

Installed capacity utilization measures the fraction of productive capacity actually in use; it is the very variable that organizes the four indicators in this block: a sustained rise toward maximum capacity acts as the direct trigger pushing the Production track into an expansion phase, while a sustained decline pushes it toward contraction.

Inventory levels measure the stock of produced but unsold goods. A sustained accumulation of inventory above normal levels is the most direct signal of structural overcapacity, whereas a drop to minimum levels signals a supply shortage; depending on which extreme it moves toward, the inventory level itself foreshadows one of these two anomalies.

Productivity per worker measures the output generated per unit of labor. Its stagnation—occurring as installed capital ages—serves as an early warning sign of abrupt technological obsolescence: it is not that productivity per worker suddenly drops, but rather that it ceases to grow precisely when the installed capital ought to be yielding higher returns than it currently does.

Taken together, these four indicators allow for monitoring the gap between installed capacity and effective demand from various angles: the industrial production index and inventory levels signal structural overcapacity or supply shortages depending on the direction in which that gap shifts; installed capacity utilization directly triggers the transition between expansion and contraction; and productivity per worker, when viewed alongside the aging of installed capital, foreshadows abrupt technological obsolescence.
