Suppose an economy’s marginal propensity to consume (MPC) is 0.6. Then
a. 1 + MPC+ MPC2+ MPC3= 1.844 and, if we continued adding up terms in this
geometric series, we would get closer and closer to the multiplier value of 1.96.
b. 1 + MPC+ MPC2+ MPC3= 1.844 and, if we continued adding up terms in this
geometric series, we would get closer and closer to the multiplier value of 3.
c. 1 + MPC+ MPC2+ MPC3= 2.176 and, if we continued adding up terms in this
geometric series, we would get closer and closer to the multiplier value of 3.
d. 1 + MPC+ MPC2+ MPC3= 2.176 and, if we continued adding up terms in this
geometric series, we would get closer and closer to the multiplier value of 2.5.
