Consider the Economy using the Aggregate Demand (AD) and Aggregate Supply (AS). MPC is the Marginal Propensity to Consume, The RR is the Required Reserves. The MPC is 0.75; The RR is 10% The full employment equilibrium GDP is 900. Price Level AD1 800 AS Real GDP Using the spending multiplier calculate the amount of change in government spending that would bring this economy to full employment. Show the change. Part 2 (Part 1 Continued) Monetary Policy_(5 Points) The Money Supply is 400. Money Demand (MD) = 200 - 625r +0.75 Y and the Money Supply (MS) = 400. Equilibrium is where MD = MS, thus the equation to solve for the interest rate is 400 = 200 - 625r +0.75 Y. Recall Real GDP is 800 before the fiscal policy action. Note: Y is Real GDP; r is the interest rate. i. Calculate the interest rate when GDP is 800. (when MD = MS) ii. Calculate the MD when Y = 900 at the current interest rate. iii. What is the change in MD when Y increases from 800 to 900? iv. Using the RR, by how much will the Federal Reserve need to increase the Money Supply to keep the interest rate at the current level?
