2. What
assumptions cause the immediate-short-run aggregate supply curve to be
horizontal? Why is the long-run aggregate supply curve vertical? Explain the
shape of the short-run aggregate supply curve. Why is the short-run curve
relatively flat to the left of the full-employment output and relatively steep
to the right? LO2

3.
Other things equal, what effects would each of the following have on aggregate
demand or aggregate supply? In each case
use a diagram to show the expected effects on the equilibrium price level and
the level of real output. LO3
a. A

b. A
major increase in Federal spending for health care (with no increase in taxes).
c. The
complete disintegration of OPEC, causing oil prices to fall by one-half.

f. A
12 percent increase in nominal wages (with no change in productivity).
g. A

4.
Other things equal, what effect will each of the following have on the
equilibrium price level and level of real output? LO3
a. An
increase in aggregate demand in the steep portion of the aggregate supply
curve.
b. An
increase in aggregate supply with no change in aggregate demand (assume that
prices and wages are flexible upward and downward).
c. Equal
increases in aggregate demand and aggregate supply.
d. A
reduction in aggregate demand in the flat portion of the aggregate supply
curve.
e. An
increase in aggregate demand and a decrease in aggregate supply.

In early 2001 investment spending sharply declined in the United States. In the 2 months following the September 11,
2001, attacks on the United States, consumption also declined. Use AD-AS analysis to show the two impacts on
real GDP. LO4
