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.
