a) Consider an AD-AS model with Static Expectations. Show how changes in monetary policy generate short-run movements in output.
(b) Consider an AD-AS model with Rational Expectations. Show how changes in the unanticipated component of monetary policy generate short-run movements in output.
(c) Explain how overlapping wage contracts generate persistence in output when there are monetary policy shocks.
In a certain economy, the Dynamic Aggregate Supply (DAS) line is represented by the function

π₁ = Ę ₁ = ₁ π + α ( Y₁ − Ÿ) + D and the inflation expectations formation mechanism is adaptive, that is,
E₁+1 Absent a supply shock (v₁ = 0), in a figure representing period t inflation rate, π, on the
vertical axis, and period t output, Y₁, on the horizontal axis, the period t DAS line will pass through the

Hi, could you help me solve this problem?
Consider an increase in global oil and gas prices from the point of the euro area (that does not produce much oil or gas itself). Think of this shock as a supply shock and use the AD-AS -model to explain how it is likely to affect output (or unemployment) and inflation. How does your result relate to the original Phillips curve? Your answer should include a graph and a short explanation in words.
