Suppose the economy is in a long-run equilibrium.
a. Draw a diagram to illustrate the state of the economy. Be sure
to show aggregate demand, short run aggregate supply, and long-run
aggregate supply.
b. Now suppose that a stock market crash causes aggregate demand to
fall. Use your diagram to show what happens to output and the price
level in the short run. What happens to the unemployment
rate?
c. Use the sticky-wage theory of aggregate supply to explain what
will happen to output and the price level in the long run (assuming
no change in policy). What role does the expected price level play
in this adjustment? Be sure to illustrate your analysis in a
graph.
