Question
Suppose the Phillips curve is
and the Aggregate Demand curve is
Tt = Tt1+3ytot
Yt = at 5(πt - 0.02)
where at = Ot = 0 in the steady state.
(a) Calculate the steady state values of output and inflation in this economy.
(b) Calculate the short- and long-run responses of the economy to the following shocks (use a
table to report your answers, as well as show them graphically on the AD-AS graph, as well
as plot inflation and output against time):
(1) A one-time decrease in ot to -0.05.
(2) A one-time increase in at to 0.05 (at returns to 0 thereafter).
(3) A permanent decrease in the Fed's inflation target from 0.02 to 0.
