MARGINAL PROPENSITY TO CONSUME: The proportion of each additional dollar of household income that is used for consumption expenditures. Or alternatively, this is the change in consumption expenditures due to a change in disposable income. Abbreviated MPC, the marginal propensity to consume is the slope of the consumption or propensity-to-consume line that forms the foundation for Keynesian economics. As such, it also takes center stage for the slope of the aggregate expenditure line and the multiplier effect. The sum of the marginal propensity to consume and the related concept, the marginal propensity to save, is equal to one.

INTERCEPT, SAVING LINE The intercept of the saving line indicates autonomous saving, saving that does not depend on the level of income or production. This can be thought of as the baseline level of saving that would be undertaken if income falls to zero. Autonomous saving is affected by the consumption expenditures determinants, which cause a change in the intercept and a shift of the saving line. The value of the intercept of the saving line is the negative of the value of the intercept of the consumption line.
