TWO-SECTOR INJECTIONS-LEAKAGES MODEL: A model used to identify equilibrium in Keynesian economics based on injections (investment) and leakages (saving) for the two basic sectors (household and business). Equilibrium is achieved at the intersection of the saving line, S, and the investment line, I.
