DIRECT: The mathematical notion that two variables change in the same direction, that is, an increase in X goes with an increase in Y, or a decrease in X goes with a decrease in Y. The alternative to a direct relation is an inverse relation, in which an increase in one variable goes with a decrease in the other. Direct relations are graphically illustrated by positively-sloped curves, a common example being the supply curve.

MARGINAL PROPENSITY TO SAVE The proportion of each additional dollar of household income that is used for saving. The marginal propensity to save (abbreviated MPS) is another term for the slope of the saving line and is calculated as the change in saving divided by the change in income. The MPS plays a central role in Keynesian economics. It quantifies the saving-income relation, which is the flip side of the consumption-income relation, and thus it reflects the fundamental psychological law. It is also a critical to the multiplier process. A related saving measure is the average propensity to save.
