Answer: Imported goods are sometimes referred to as a source of "leakage" because they can have the effect of transferring income that was earned in one country to another country. The funds used to purchase the imports leave the immediate area, resulting in an outflow from the domestic area.

Leakages from the spending stream include savings, taxes and imports. Injections include investment spending, government spending and exports. When leakages equal injections, total spending will equal total output and the macroeconomy will be in equilibrium.
