Determinants of aggregate demand
The following graph shows a decrease in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the left from AD1AD1 to AD2AD2, causing the quantity of output demanded to fall at all price levels. For example, at a price level of 140, output is now $200 billion, where previously it was $300 billion.
The graph below is associated with a hypothetical country. Consider an increase in aggregate demand (AD). Specifically, aggregate demand shifts to the right from AD1AD1 to AD2AD2, causing the quantity of output demanded to rise at each price level. For instance, at a price level of 140, output is now $400 billion, where initially it was $300 billion.
Fill in the missing values in the table by selecting the change in each scenario required to increase aggregate demand.
Change required to increase AD
Expected rate of return on investment. (decrease/increase)
Incomes in other countries (decrease/increase)
Consumer expectations about future profitability. (improve/worsen)
Government spending (increase/decrease)
Suppose that the price level is constant and that investment decreases sharply. How would you show this decrease in the aggregate expenditures model? What would be the outcome for real GDP? How would you show this fall in investment in the aggregate demand–aggregate supply model, assuming the economy is operating in what, in effect, is a horizontal section of the aggregate supply curve?

Assuming that the aggregate price level is constant, the interest rate is fixed in both countries, and there are no taxes and no foreign trade, complete the accompanying tables to show the various rounds of increased spending that will occur in both economies if the marginal propensity to consume is 0.5 in Westlandia and 0.75 in Eastlandia.

Economists forecast that if the government takes no action and the economy continues to grow at the current rate, aggregate demand in 2028 will be given by the curve labeled ADAADA, resulting in the outcome given by point A. If, however, the government pursues an expansionary policy, aggregate demand in 2028 will be given by the curve labeled ADBADB, resulting in the outcome given by point B.
