In the basic New Keynesian model, suppose that there is an increase in government spending.
• First, suppose that the central bank does nothing (accommodates the shock). Illustrate onthe graphs and explain what will be the effects on inflation and output?
• Second, suppose that economy initially has inflation equal to the central bank’s inflationtarget and an output gap of zero. What action do you expect the central bank wouldundertake? Illustrate you answer on the graph and explain.
PLEASE SHOW ALL HAND WRITTEN STEPS AND WORK!
Using the AD-AS model, discuss the money neutrality in the short-run and in thelong-run.

This economy has been hit by a positive demand shock (represented by point B). Before the shock the economy was at equilibrium (represented by point A).

If the demand shock is temporary, once the adjustment process guided by the central bank finishes, the economy will be back at the same output (Yt=ye) and interest rate (rt = rs). At point B there is a positive bargaining gap between the WS-PS which puts pressure on prices to increase.

Suppose Central Bank A cares only about keeping the price level stable and Central Bank B cares only about keeping output and employmentat their natural levels.
