If a shortage of money stayed where it started, it would be a problem for lenders and no one else. The reason scarcinality is a theory about the whole economy, and not just about banking, is that the shortage does not stay put. It descends. And as it descends it changes its appearance, until what began as a frozen credit market looks for all the world like empty shelves and idle hands. This post traces that descent, which Irving Fisher mapped almost a century ago.
The trap in falling prices
Start at the moment of the scramble. Everyone is reaching for cash, and to raise it they sell whatever they can: inventory, equipment, assets. When a great many sellers all rush the exits at once, prices fall. So far this might sound harmless, even helpful, since cheaper goods could mean buyers step in. But there is a trap, and the trap is debt.
Debts are fixed in money terms. You owe a fixed number of dollars regardless of what those dollars can buy. So when prices fall, the real weight of every debt rises. The dollar you owe now represents more goods, more hours of work, more sacrifice than it did when you borrowed it. The harder borrowers try to escape their debts by selling, the more they drive prices down, and the more the real burden of what remains grows. Fisher put it in a single unforgettable line: the more the debtors pay, the more they owe. The act meant to provide relief makes the situation worse.
The descent into the real economy
Now watch what this does to ordinary business. A firm cannot sell its output at a price that covers its fixed debts, so it cuts production. Not because it has forgotten how to produce, and not because the goods are unwanted, but because producing at those prices loses money. To cut costs it lays off workers. Not because there is no work, but because the wage bill is unbearable against collapsing revenue.
Those laid-off workers were also customers. With their incomes gone, they stop spending, which pulls demand away from other firms, which cut their own production and their own workers in turn. Round and round it goes, each contraction feeding the next. This is the downward spiral every account of a depression describes. Scarcinality adds one thing: a name for what is actually spiraling. It is not goods running out. It is a shortage of money reproducing itself, level by level, dressed up as a shortage of goods and work.
Plenty and want, side by side
At the bottom of the spiral you arrive at the strangest sight in economics, and the one the whole theory exists to explain. The warehouses are full. The shelves are stocked. Factories sit idle, ready to run. And people go without. Want and surplus occupy the same moment.
The textbook image is the Depression, when farmers plowed crops back into the soil and poured milk into ditches while families in the cities went hungry. It is tempting to file this under cruelty or mismanagement. It is neither. The food was not scarce. The money that would have carried it from the field to the hungry was scarce. The suffering was real, but the scarcity that produced it lived one level above the goods that appeared to have run out.
Look one level up
This is the practical heart of the theory. Faced with unsold goods and unemployed workers, the orthodox instinct is to look for a real cause: wages set too high, prices stuck in the wrong place, workers with the wrong skills in the wrong towns. Sometimes those things are present. But in a genuine money crisis they are not the binding problem, and treating them as such means reaching for tools that cannot fix what is actually broken.
Scarcinality says: look one level up. The constraint is not in the goods. It has been imported into the goods from the layer above. The counterfeit is convincing precisely because the want is real, the hunger is real, the lost jobs are real. Only the diagnosis is wrong. The next post takes up the single number people most often reach for when they try to describe this, the speed at which money moves, and explains why it is a symptom rather than the cause.
