Suppose the marginal propensity to consume (MPC)is 0.8 and there is a $2,000 increase in autonomous consumption. Given this information, real GDP will increase by

B)$2,000.
C)$2,500.
D)$10,000.

The multiplier effect is calculated as 1/(1-MPC). With an MPC of 0.8, the multiplier is 1/(1-0.8) = 5. Therefore, a $2,000 increase in autonomous consumption will increase real GDP by 5 * $2,000 = $10,000.
