REAL GDP (Billions of dollars)
In the first economy (with MPC = 0.5), the $40 billion decrease in investment causes equilibrium output to decrease by
%3D
billion. In the second
economy (with MPC = 0.6), the $40 billion decrease in investment causes equilibrium output to decrease by S
billion. Therefore, a lower MPC
is associated with a
multiplier.
Now, confirm your graphical analysis algebraically using the oversimplified multiplier formula:
Multiplier
|3|
1-MPC
For the first economy, with an MPC of 0.5, the effect of the $40 billion decrease in investment is as follows:
Change in Equilibrium Output
Change in Total Erpenditure x Multiplier
Using the same method, the multiplier for the second economy is
