LEAKAGE LINE: A line used in the injection-leakage model representing the relation between non-consumption uses of income (that is, leakages) and national income. The three leakages are saving, taxes, and imports. The foundation of the leakages line is the saving line, which is then enhanced by adding taxes and imports.
