Suppose that the economy was initially in a long-run equilibrium. Then the Federal Government decided to increase government spending by 1 trillion dollars on infrastructure. A) Use the the IS-LM and AD-AS diagrams to show the short-run effects of this policy change. Clearly label all axes, curves, and equilibrium values of variables for full credits. B) Use the the IS-LM and AD-AS diagrams to show what happens in the transition from the short run equilibrium to the new long run equilibrium. Clearly label all axes, curves, and equilibrium values of variables for full credits. C) How do the new long-run equilibrium values of r, Y, P, and I compare to their initial values?
