Assume , and suppose that is initially equal to 0. Suppose that the rate of unemployment is initially equal to the natural rate. In year , the authorities decide to bring the unemployment rate down to 3% and hold it there forever. b. Determine the rate of inflation in years , , , and . c. Do you believe the answer given in (b)

The question is incomplete. The complete question is :

Suppose that the Phillips curve is given by :

a). What is the natural rate of unemployment ?

Assuming , and suppose that is initially equal to 0. Suppose that the rate of unemployment is initially equal to the natural rate. In year t, the authorities decide to bring the unemployment rate down to 3% and hold it there forever.

b). Determine the rate of inflation in years t, t+1, t+2 and t+5.

c). Do you believe the answer given in (b)? Why or why not?

Solution :

Given the equation :

a). At ,    (Inflationary exponents are constant)

    ∴  

               = 5%

b).

   Let , then ,

    Now for year t

c). No, I do not believe as

    , but πt comes out to be 4%, but .

If inflation is consistently positive, why to make the expectations of zero percentage.

answer; /// the correct answer is (shared); /// good luck

there's 11 people for the 1st position. then, no matter who gets it, there's only 10 left for the second, and then 9 left for the third. 11 x 10 x 9 = 990.   the answer is there are 990 different ways the positions can be filled by these applicants
