In a certain economy, when income is $400, consumer spending is $325. The value of the
multiplier for this
economy is 3.33. It follows that, when income is $450, consumer spending is
a.
$360. For this economy, an initial increase of $50 in consumer spending translates into a
$266.67 increase in
aggregate demand.
b.
$360. For this economy, an initial increase of $50 in consumer spending translates into a
$166.50 increase in
aggregate demand.
c.
$341.67. For this economy, an initial increase of $50 in consumer spending translates into a
$266.67 increase
in aggregate demand.
d.
$341.67. For this economy, an initial increase of $50 in consumer spending translates into a
$166.25 increase
in aggregate demand.

Suppose an economy’s marginal propensity to consume (MPC) is 0.6. Then
a.
1 + MPC + MPC 2 + MPC 3 = 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 + MPC 2 + MPC 3 = 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 + MPC 2 + MPC 3 = 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 + MPC 2 + MPC 3 = 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.
