Problem: Assume the commodity market and the money market for an economy are described by the following IS and LM curve.
IS: Y = 11,000 - 250r; LM: Y = 8,000 + 250r.
Q1. Compute the equilibrium interest rate (r) and equilibrium real output (Y).
Q2. Suppose that fiscal policymakers raise taxes and cut government spending. As a result, the IS curve shifts left to Y = 10,000 - 250r. Compute the new equilibrium interest rate (r) and new equilibrium real output (Y).
Q3. Suppose that there is no change in fiscal policy, so that ther IS curve is Y = 11,000 - 250r. Instead monetary policymakers take action to reduce the money supply so that the LM curve shifts to Y = 7,000 + 250r. Compute equilibrium interest rate (r) and new equilibrium real output (Y).
