involuntary unemployment

Involuntary unemployment, a concept central to Keynesian economics, occurs when a capitalist economy fails to automatically generate full employment. This situation arises not from workers demanding wages higher than the value of their product, but from a lack of "effective demand"—meaning there's insufficient demand for goods and services.1234

Keynes argued that businesses won't hire workers if they can't sell the resulting products. This can lead to persistent unemployment, especially if wages and prices are inflexible. The theory suggests that government intervention through fiscal policy, such as adjusting taxes and public spending, can stimulate demand and help restore full employment.324
