Consider the AD-AS model discussed during the lectures. Assume
that the aggregate demand curve is given by Y=8-0.5 π, that the
long run aggregate supply curve is given by Yp=7, that the short
run aggregate supply curve is given by π = π_expect + 0.3(Y-Yp),
and that the monetary rule is given by r=1+0.3 π.
(b)Suppose the economy is in equilibrium at the potential level
of output, with inflation expectations equal to actual inflation,
which equals 2%. A loss of consumer confidence hits the economy and
leads to a sudden drop in consumption. Use the model to interpret
what happens in the short run and in the long run if the central
bank does not intervene exogenously with an expansionary monetary
policy.
