a. under this assumption that the expected inflation rate does not adjust, what will be the final inflation rate?
b. What will be the final output level under the same assumption?
c. What will be the final inflation rate if the expected inflation rate is allowed to adjust?
d. What will be the expected inflation rate if th expected inflation rate is allowed to adjust?
e.What will be the final output level if the expected inflation rate is allowed to adjust?

2. Assume that the economy is operationg at the natural output level (Y=100) with an inflation rate, nominal GDP growth rate, and inflationary expectation rate all at 2 percent .Assume that a supply side shock occurs that shifts the SP curve up by an additional 3 percent.
