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.
