A Keynesian economy is described by the following equations. Consumption Cd = 250 + 0.5(Y - T) - 250r Investment Id = 250 - 250r Government purchases G = 300 Government taxes T = 300 Real money demand L = 0.5Y - 500r + πe Money supply M = 3000 Full-employment output Y = 1250 Expected inflation πe = 0 (HINT a: The expected rate of inflation is assumed to equal zero so that money demand depends directly on the real interest rate, which equals the nominal interest rate. Domestic Savings, Sd =Y - C - G. In equilibrium set domestic savings equal to domestic investment, so Sd = Id) Calculate the values of the real interest rate (r), consumption (Cd), and investment (Id) for the economy in general equilibrium.

The graph below depicts an economy where an increase in aggregate demand has caused inflation. Assume the government decides to conduct fiscal policy by decreasing government purchases to restore full-employment GDP. Instructions: Enter your answer as a whole number. If you are entering a negative number include a minus sign. a. How much does aggregate demand need to change to restore the economy to its long-run equilibrium? $ -160 Numeric ResponseEdit Unavailable. -160 incorrect. billion b. If the MPC is 0.9, how much do government purchases need to change to shift aggregate demand by the amount you found in part a? $ billion Suppose instead that the MPC is 0.8. c. How much does aggregate demand and government purchases need to change to restore the economy to its long-run equilibrium? Aggregate demand needs to change by $ billion and government purchases need to change by $ billion.
Question 2Explain fully how the AS/AD model is an update of the Keynesian model. Provide a graph of the equilibrium income in the Keynesian model, and compare it with a graph of the equilibrium income in the AS/AD model. Why are negative supply shocks much more harmful to an economy compared with negative demand shocks? Compare the policies which can be used to address negative demand shocks with policies to address negative supply shocks.
The following equations describe a Keynesian model of a closed economy: C = 500 - 0.5(Y - T) - 100r I = 350 - 100r L = 0.5Y - 200i πe = 0.05 G = T = 200 Y = 1850 M = 3560 a.

Draw and properly label an AD-AS model to show Keynesian, intermediate, and neoclassical zones. Then, briefly explain the levels of unemployment, inflation and real GDP in each zone, and also confirm whether all three goals of a macro economy are being achieved in each zone. 2. Draw and properly label the AD-AS graphs or one AD-AS graph to show recessionary and inflationary gaps. Then, discuss in detail how Keynesians suggest that recessionary and inflationary gaps be closed. 3. Draw and properly label AD-AS graphs or one AD-AS graph to show recessionary and inflationary gaps. Then, discuss in detail how neoclassicals suggest that recessionary and inflationary gaps be closed.
In the New Keynesian model, suppose that in the short run the central bank cannot observe aggregate output or the shocks that hit the economy. However, the central bank would like to come as close as possible to economic efficiency. That is, ideally the central bank would like the output gap to be zero. Suppose initially that the economy is in equilibrium with a zero-output gap. (a) Suppose that there is a shift in money demand. That is, the quantity of money demanded increases for each interest rate and level of real income. How well does the central bank perform in relative to its goal? Explain using diagrams. (b) Suppose that firms expect total factor productivity to increase in the future. Repeat part (a). (c) Suppose that total factor productivity increases in the current period. Repeat part (a). (d) Explain any differences in your results in parts (a)–(c) and explain what this implies about the wisdom of following an interest rate rule for the central bank. Problem 6 assumes that…

Explain the concept of “Divine Coincidence” and clearly state the cases where it holds and where it does not hold in the New-Keynesian model. In detail.
Which of the following describes the use of Keynesian macroeconomic policy to resolve an inflationary gap problem in the economy? a) Unemployment, resulting from the short-run product markets equilibrium being below Long-run Aggregate Supply (LRAS), causes wages to decline, which increases short-run Aggregate Supply (AS), until long-run equilibrium is attained at full employment level of income and a lower price level. b) Government spending is increased, increasing Aggregate Demand (AD) to a level sufficient to attain long-run equilibrium at full employment level of income and a higher price level. c) In attempting to produce beyond the economy's natural level of GDP, producers bid up wages and prices of other resources, causing the short-run Aggregate Supply (AS) to decrease to the point where long-run equilibrium is restored. d) Taxes are increased reducing Aggregate Demand (AD) to a level consistent with full employment.
