What was not sold went into unsold inventory. In other words, the producers got stuck with the unsold goods. Because actual sales fell short of planned sales, the producers will adjust the planned sales downward and produce less the next period hoping that the actual sales will be equal to the planned sales.
In a simplified closed economy with no government, households plan to save a certain amount planned leakage , but the actual saving actual leakage may be less than planned if producers do not plan to invest planned injection the same amount as the planned saving. When the planned injection is less than the planned leakage, households are disappointed in their actual saving and try to save even more next period.
If the planned investment again does not match the planned saving, the output pie will shrink even more. Saving and taxes are the two leakages. Investment and government purchases are the two injections. Four-Sector Model : As the name suggests, all four macroeconomic sectors--household, business, government, and foreign--are included in the four-sector Keynesian model.

The first paper currency used in North America was pasteboard playing cards "temporarily" authorized as money by the colonial governor of French Canada, awaiting "real money" from France. It is very easy to say yes. In Keynesian economics this is a simple model of a static economy, based on the assumption of a one-period lag between income and expenditure.
If there were neither injections of new purchasing power into this flow nor leakages out of it, total income in each period would be equal to the spending arising from incomes in the previous period, and total income would remain constant over time.
Injections of new purchasing power not derived from last period's income can be made by investment, government spending, or exports. Leakages from the circular flow, by which this period's income does not lead to incomes next period, are caused by saving, tax payments, or imports. If injections and leakages are equal, incomes will be constant; if injections exceed leakages, incomes rise over time; and if leakages exceed injections, incomes fall.
