π $\bar u$

Essay

The relationship between inflation and unemployment is given by
π = π^e - 4(u - $\bar u$ ).(a)Draw a diagram showing a long-run Phillips curve and two short-run Phillips curves that contain the following points:
A: π = .04,π^e = .04
B: π = .08,π^e = .08
C: π = .04,π^e = .08
D: π = .08,π^e = .04
Label points A,B,C,and D in your diagram.
The unemployment rate at point A equals .05.
(b)What are the values of the natural rate of unemployment and the unemployment rates at points B,C,and D?
