Suppose firms become very optimistic about future business conditions and invest heavily in new capital
equipment.
a. Draw an aggregate-demand/aggregate-supply diagram to show the short-run effect of this
optimism on the economy. Label the new levels of prices and real output. Explain in words
why the aggregate quantity of output supplied changes.
b. Now use the diagram from part (a) to show the new long-run equilibrium of the economy.
(For now, assume there is no change in the long run aggregate-supply curve.) Explain in words
why the aggregate quantity of output demanded changes between the short run and the long
run.
c. How might the investment boom affect the long run aggregate-supply curve? Explain
Assume that the long-run aggregate supply curve is vertical at Y = 3.000 while the short-run aggregate supply curve is horizontal at P=1.0, . The aggregate demand curve is Y = 2(M / P) and M = 1,500.
Suppose the aggregate demand function shifts to Y = (1.5)(M / P) . What are the short- run values of P and Y? Show the change in short and long- run equilibrium graphically . Describe the short- run and long- run effects of the change in demand .
Suppose our economy is in macroeconomic equilibrium (also called "general equilibrium") with an upward-sloping aggregate supply curve and a downward-sloping aggregate demand curve. An increase in aggregate demand will:
Question 5 options:
a)
Increase aggregate supply.
b)
Decrease the price level.
c)
Causes the aggregate supply to shift to the right.
d)
Increase real GDP.
e)
Reduce the number of discouraged workers in the unemployment rate.
