Consider the effects of a permanent decrease in the rate of nominal money growth
Suppose that the economy can be described by the following three equations:
πΌπ β πΌπβπ = βπ. π(πππ β π%)
Okunβs law
π π β π πβπ = βπ. π(πΌπ β π%)
Phillipβs curve
πππ = πππ β π π
Aggregate demand
(a) Reduce the three equations to two by substituting gyt from the aggregate demand
equation into Okunβs law. Assume initially that πΌπ = πΌπβπ = π%, gmt = 13%, and Ξ t =
10%, what was the rate of inflation last year?.
(b) Explain why these values are consistent with the statement βInflation is always and
everywhere a monetary phenomenon.β
Now suppose that money growth is permanently reduced from 13% to 3%, starting in
year t.
(c) Compute unemployment and inflation in years t, t + 1, β¦, t + 10.
(d) Does inflation decline smoothly from 10% to 3%? Why or why not?
