How do I solve this?

Transcribed Image Text:Consider an AD-AS model with AD curve Y-Y* = -ay(π*) + ED and AS
curve π = +B(Y - Y*) + Es with parameter values a = 0.5, y = 1, 0 = 1
and 3 = 0.5 and with inflation target * = 0.02 and potential output normalised to
Y* = 1.
Starting from a long-run equilibrium with = *, suppose there is a temporary
demand shock p = -0.05. Which of the following is TRUE?
In the short run, output is 4% below trend
In the short run, output is 4% above trend
In the short run, inflation is 3%
