Consider two closed economies that are identical except for their marginal propensity to consume (MPC). Each economy is currently in equilibrium with real GDP and total expenditure equal to $100 billion, as shown by the black points on the following two graphs. Neither economy has taxes that change with income. The grey lines show the 45-degree line on each graph. The first economy's MPC is 0.5. Therefore, its initial total expenditure line has a slope of 0.5 and passes through the point (100, 100). The second economy's MPC is 0.70. Therefore, its initial total expenditure line has a slope of 0.70 and passes through the point (100, 100). Now, suppose there is an increase of $30 billion in investment in each economy.

The second economy's MPC is 0.70. Therefore, its initial total expenditure line has a slope of 0.70 and passes through the point (100, 100).
Now, suppose there is an increase of $30 billion in investment in each economy.
