Chapter 17: Q. 15 (page 395)

The policy relevance of new Keynesian inflation dynamics based on the theory of small menu costs and sticky prices depends on the exploitability of the implied relationship between inflation and real GDP. Explain in your own words why the average time between price adjustments by firms is a crucial determinant of whether policymakers can actively exploit this relationship to try to stabilize real GDP.

Short Answer

Expert verified

There would be a brief run trade-off between real GDP and inflation

Step by step solution

01

Given Information 

Its exploitability of inferred link among price and economic GDP is crucial to a notion of little menu costs and sticking price.

02

Explanation

  • Considering the policy relevance of recent Keynesian inflation dynamics, initially there's slow adjustment of the worth level in response to the increased aggregate demand followed by later higher inflation.
  • If the everyday time between price adjustments by firms is critical, then within the short run aggregate supply curve would be considered as horizontal, as hypothesized by the new Keynesian theorists.
  • As a result, there would bea brief run trade-off between real GDP and inflation.

Suppose that more unemployed people who are classified as part of frictional unemployment decide to stop looking for work and start their own businesses instead. What is likely to happen to each of the following, other things being equal?

a The natural unemployment rate

b The economy's Phillips curve

How might low inflation expectations on the part of the public help to hold down actual inflation? Explain.

Explain whether the cyclical unemployment rate is positive, zero, or negative at the point E2, after the shift in the aggregate demand curve from AD1to AD2. In addition, explain whether the cyclical unemployment rate is positive, zero, or negative at a point E3, following the shift in the short-run aggregate supply curve from SRAS, toSRAS.

Take a look at Figure 17-3. Explain whether the cyclical unemployment rate is positive, zero, or negative at point E2, after the shift in the aggregate demand curve from AD1to AD2. In addition, explain whether the cyclical unemployment rate is positive, zero, or negative at point E3the shift in the short-run aggregate supply curve from SRAS1to SRAS2.

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.
