Assume that an economy is governed by the Phillips curve p = pe " 0.5(u " 0.06), where
p = (P " P"1)/P"1, pe = (pe " P"1)/P"1, and 0.06 is the natural rate of unemployment.
Further assume pe = p"1. Suppose that, in period zero, p = 0.03 and pe = 0.03that is, that
the economy is experiencing steady inflation at a 3-percent rate.
a. Now assume that the government decides to impose whatever demand is necessary to
cut unemployment to 0.04. Suppose the government follows this policy for periods 1
through 5. Create a table of p and pe for these five periods.
b. Assume that, for periods 6 through 10, the government decides to hold
unemployment at 0.06. Create another table of p and pe for these five periods. Is there
any reason to expect the inflation rate to go back to 0.03?
c. If the government persisted in its behavior under part a, do you think the public
would continue for long forming expectations according to pe = p"1? Why?

rate, the result would be accelerating inflation or deflation.
