CHAPTER 10: OUTPUT, INFLATION, AND UNEMPLOYMENT:
ALTERNATIVE VIEWS
Additional Questions
Essay Questions and/or Problems:
1. According to the theory of the natural rate of unemployment, can the policymaker "peg" the
unemployment rate at some arbitrarily determined target rate? Why or why not? What is the
eventual result of attempting such an action?
2. What is meant by the natural rate of unemployment? Is the natural rate of unemployment a
constant value? According to the monetarist view, does expansionary monetary policy
lower the natural rate of unemployment temporarily or permanently?
3. Assume that there is a positive supply shock, such as an increase in the productivity of
labor. What impact will this have on the short-run and long-run Phillips curve? What will
be the observed relationship between inflation and unemployment? Provide a graph of the
Phillips curve and AD/AS to illustrate.
4. Use the natural rate Phillips curve to analyze a change in regime at a central bank that is
committed to maintaining a lower level of inflation than previous regimes. What will be the
short-run impact of such a change in policy? The long-run impact?
5. Does the Keynesian view of the short-run Phillips curve differ from the monetarist view?
6. If Keynesians acknowledge that there does exist a vertical aggregate supply curve in the
long-run, then, does that invalidate their belief in the use of monetary and fiscal policy to
stabilize output? Explain.
7. What is meant by "hysteresis?" Is hysteresis consistent with Friedman's natural rate
hypothesis?
8. The divergent behavior of unemployment in the United States and Europe, especially in the
1990s, been attributed to different structural characteristics of labor markets in the two
regions. Describe the labor market in the United States, making sure to discuss differences
in the natural rate of unemployment across the two regions.
9. Milton Friedman argued that the Phillips curve is most accurately described by the
following equation:
e
10. Milton Friedman often referred to money as "neutral". What do you think that he meant by
this? He also termed the phrase "the natural rate of unemployment". What is natural about
the natural rate of unemployment?
Additional Essay Questions and/or Problems:
11. Suppose that a central bank thinks that the natural rate of output is above where the “true”
natural rate of output actually is (i.e. Utarget < UNR). What will be the long run impact of
such a policy? Use a Phillips curve graph to illustrate. How does your answer depend upon
what you assume to be true about how the public forms their expectations?
12. Milton Friedman believes that there will be only a temporary trade-off between inflation
and unemployment. Explain why.
13. Suppose that there is a decline in autonomous investment. Would a monetarist favor an
expansionary monetary policy to offset the short-run effects of this shock? Explain why or
why not.
14. Why is the assumption that the expected inflation rate is constant crucial to the concept of
the Phillips curve? Why is it crucial to its use in stabilization policy? Under what
circumstances do you think that constant expected inflation is a good assumption?
15. Suppose that there is a permanent increase in the level of government spending financed by
a larger budget deficit. What would Keynesians predict would happen to inflation and
unemployment as a result? What would Monetarists predict would happen to inflation and
unemployment as a result? Provide graphs of the Phillips curve to illustrate.
16. Consider the following quote from Milton Friedman in his article The Role of Monetary
Policy (pg. 11):
17. Suppose that an economy begins at the natural rate of unemployment and that the expected
inflation rate is equal to the actual price level in the preceding period. If the central bank
makes a permanent reduction in the money supply, draw a graph illustrating the path of
inflation and unemployment over time. Illustrate your intuiton using IS/LM, AD/AS, and
Phillips curve graphs.
18. Suppose that an economy has the following Phillips curve:
)04.(25.−−= uPP e
a. What is the natural rate of unemployment in this economy?
b. What is the tradeoff between inflation and unemployment in this economy?
c. Graph this Phillips curve if the expected rate of inflation is 3percent, or .03.
d. If current inflation is 4 percent and expected inflation is 3 percent, what is current
unemployment?
