Term leakage line Definition: 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. The other part of the injection-leakage model is a line representing injections. The intersection of the injection and leakage lines identifies equilibrium aggregate output, or Keynesian equilibrium.
