average propensity to consume การใช้

• Secondly, average propensity to consume falls as income rises.
• In a standard Keynesian model, the MPC is less than the average propensity to consume ( APC ) because in the short-run some ( autonomous ) consumption does not change with income.
• Over the long-run, as wealth and income rise, consumption also rises; the marginal propensity to consume out of long-run income is closer to the average propensity to consume.
