Evaluate the following statement: "In an important sense, the term policy irrelevance proposition is misleading because even if the rational expectations hypothesis is valid, economic policy actions can have significant effects on real GDP and the unemployment rate."

Short Answer

Expert verified

As a result,an unanticipated rise in the supply of money may affect changes in prices and realGDP except in the short term, but these changes will not be seen in the long run.

Step by step solution

01

Step: 1 Introduction:

If the money supply is suddenly raised, the quantity demanded will move to the right. This rise in consumer spending will raise both the price level and actual GDP.Workers may seek greater pay in order to preserve their real earnings from falling as a result of price level changes, claiming that nominal wages have increased owing to changes in prices. The total short-run supply curve will move higher vertically as a result of this.

Step: 3 real GDP and the unemployment rate:

It is obvious from the following figure that there is still a growth in the price point as well as gross Domestic product. The shift from SRAS1to SRAS2denotes a shift in the quick aggregate supply curve as a result of this shift in the money supply. As a response, the economy shifts from equilibrium Ato equilibrium B. This will be reflected in pricing adjustments. With a rise in the price, the equilibrium level will shift once more. The equilibrium point has now shifted from Bto C. This adjustment lowers real GDPby role="math" localid="1651835869787" $0.3trillionand raises the prices index from 110-122.To summarise, an unanticipated rise in the supply of money may affect changes in prices and realGDP except in the short term, but these changes will not be seen in the long run.

Suppose that people who previously had held jobs become structurally unemployed due to establishment of new government regulations during a period in which the inflation rate remains unchanged. Would the result be a movement along or a shift of the short-run Phillips curve? Explain your reasoning.

Consider a situation in which a future president has appointed Federal Reserve leaders who conduct monetary policy much more erratically than in past years. The consequence is that the quantity of money in circulation varies in a much more unsystematic and, hence, hard-to-predict manner. According to the policy irrelevance proposition, is it more or less likely that the Fed's policy actions will cause real GDP to change in the short run? Explain.

What is the most recent approximate interval during which the cyclical unemployment rate has been positive? During what most recent approximate interval was the cyclical unemployment rate negative? Explain briefly.

Why would using the U6 unemployment rate instead of the traditional unemployment rate almost certainly yield different "appropriate" activist macroeconomic policies?

Take a look at panel (b) of Figure 17-4, and suppose that the economy initially operates at point A, at which the inflation rate is 0percent and the unemployment rate is 6percent, which is the natural rate of unemployment. Then the inflation rate increases to 3percent. Does reduced cyclical, frictional, or structural unemployment account for the resulting decrease in the unemployment rate at pointB ? Explain briefly.
