Q. |
Over short period, when income rises, average propensity to consume usually - |
A. | rises |
B. | falls |
C. | remains constant |
D. | fluctuates |
Answer» B. falls | |
Explanation: Keynes postulated that aggregate consumption is a function of aggregate current disposable income. The Keynesian consumption function is written as: C = a + eY a > 0, 0 < c < 1; where a is the intercept, a constant which measures consumption at a zero level of disposal income; c is the marginal propensity to consume (MPC); and Y is the disposal in-come. So asincome increases, average propensity to consume (APC = C/Y) falls. |
