Suppose that the relationship between inflation rate (π) and unemployment rate (u) is described by the following equation: πt – πte = (m + z) – αut where m = 0.05, z = 0.04, and α = 2. In this economy, the authorities keep unemployment rate at 4% forever. a. If the modified Philips curve describes the relationship between π and u correctly, how should “πte” be specified? Rewrite the equation using this specification. Assume that πt–1 = 1%. Compute πt, πt+1, and πt+2. b. Do you believe the answer in part (a)? Why or why not? c. Derive the natural rate of unemployment.

Question
Suppose that the relationship between inflation rate (π) and unemployment rate (u) is described by the following equation:
πt – πte = (m + z) – αut
where m = 0.05, z = 0.04, and α = 2. In this economy, the authorities keep unemployment rate at 4% forever.
a. If the modified Philips curve describes the relationship between π and u correctly, how should “πte” be specified? Rewrite the equation using this specification. Assume that πt–1 = 1%. Compute πt, πt+1, and πt+2.
b. Do you believe the answer in part (a)? Why or why not?
c. Derive the natural rate of unemployment.
