Assume the economy is described by the following equations:
Phillips Curve:
Okun's Law:
T = Tt-1 – 1.5% – (ut – 0.05)
AY/Y = 3% - 3(ut– 0.05)
a) How could we know that expectations are not rational in this setup?
b) Imagine that last year's inflation is equal to 11%. Imagine the Federal Reserve raises
unemployment to 8% and keeps it there until inflation reduces to 2%. How many years of
8% unemployment would it take for inflation to reach 2%?
c) What values of inflation would we observe over time as inflation reached 2%?
d) How much output is lost to bring down inflation to 2%?
