SLOPE, SAVING LINE: The positive slope of the saving line is also termed the marginal propensity to save (MPS). This slope is greater than zero but less than one, reflecting induced saving and the Keynesian psychological law of consumer behavior that saving increases by less than the increase in income. The slope of the saving line provides the foundation for the slope of the leakages line used in the injections-leakages model. It thus also affects the magnitude of the multiplier process.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants.

Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
