”As a matter of accounting, for aggregate output to be sold, total spending must equal the total income generated in production (whether actual income generated in production is fully spent or not in each period).
Involuntary unemployment is idle labour offered for sale with no buyers at current prices (wages). Unemployment occurs when the private sector, in aggregate, desires to earn the monetary unit of account through the offer of labour but doesn’t desire to spend all it earns, other things equal.
As a result, involuntary inventory accumulation among sellers of goods and services translates into decreased output and employment.
In this situation, nominal (or real) wage cuts per se do not clear the labour market, unless those cuts somehow eliminate the private sector desire to net save, and thereby increase spending.”
