A)real GDP and the price level both fall; real GDP is below its original level with a lower price level
B)real GDP and the price level both rise; real GDP is above its original level with a higher price level
C)real GDP and the price level both rise; real GDP returns to its original level with a higher price level
D)real GDP rises and the price level falls; real GDP returns to its original level with a lower price level
E)real GDP falls and the price level rises; real GDP is below its original level with a higher price level

Question 76

The diagram below shows an AD/AS model for a hypothetical economy.The economy begins in long-run equilibrium at point A. FIGURE 24-3
Refer to Figure 24-3.After the negative aggregate demand shock shown in the diagram (from to ),which of the following describes the adjustment process that would return the economy to its long-run equilibrium?

A)Wages would eventually fall,causing the AD curve to shift to the right,returning to the original equilibrium at point A.
B)Wages would eventually fall,causing the AS curve to shift slowly to the right,reaching a new equilibrium at point E.
C)Wages would increase,causing the AS curve to shift to the right,reaching a new equilibrium at point E.
D)Wages would increase,causing the AD curve to shift to the right,returning to the original equilibrium at point A.
E)Potential output would decrease from 1000 to 900 and a new long-run equilibrium would be established at point D.

Question 77

The diagram below shows an AD/AS model for a hypothetical economy.The economy begins in long-run equilibrium at point A. FIGURE 24-3

A)90; 900
B)110; 800
C)60; 1000
D)60; 700
E)90; 1250

Question 78

C)a large increase in the net tax rate
D)a large increase in the price of raw materials
E)a large increase in labour productivity

Question 79

Suppose Canada's economy is in a long-run equilibrium with real GDP equal to potential output.Now suppose there is an unexpected and sharp reduction in desired business investment expenditure.In the short run,________.In the long run,________.

A)real GDP and the price level both fall; real GDP is at its original level with a lower price level
B)real GDP and the price level both fall; real GDP is above its original level with a higher price level
C)real GDP and the price level both rise; real GDP returns to its original level with a higher price level
D)real GDP rises and the price level falls; real GDP returns to its original level with a lower price level
E)real GDP falls and the price level rises; real GDP is below its original level with a higher price level
