- 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.Complete the following table by matching the macroeconomic assumptions about aggregate supply to the appropriate school of thought. Assumption Classical Keynesian Only an increase in aggregate demand can move an economy out of a recession and back to potential real GDP quickly. Product prices and wages tend to be inflexible. The following graph shows the aggregate demand (ADAD) and aggregate supply (ASAS) curves for a hypothetical economy that is currently operating below its full-employment output level. That is, the economy is currently in a recession. The aggregate supply curve (ASAS) in this diagram is consistent with the view of aggregate supply. According to this viewpoint, the government should spending in response to the recession. Shift the appropriate curve on the graph to illustrate the impact of this change in government spending. ADASPRICE LEVELREAL GDP (Trillions of dollars)AD AS The prescribed…suppose a Keynesian macroeconomic model is characterized with the following equations: Y = C + I + G Goods markets C = C = 320 + 0.8YdYd = Y − TI = 40 − 40rG = 80T = 50 Money marketsMoney demand:(M/P)d = 500 + 0.8 − rMoney supply: MSP = 800Derive IS and LM equations and derive equilibrium income level and interest rate.
- Consider two standard Keynesian models. In Model 1, there are two types of consumers, Type A,who have low marginal propensities to consume, and Type B, who have high marginalpropensities to consume. In Model 2, there are only Type A consumers. Then, a decrease in theexogenous taxes would lead to higher output in Model 2 than in Model 1Consider a 4-sector Keynesian model like that discussed in class with the following characteristics: exogenous consumption=10000, exogenous taxation=4000, government spending=5000, exports=5000, planned investment=2000. The marginal propensity to save=50%, the marginal tax rate (t)=30% and the marginal propensity to import (m)=20%. The potential output for the economy is 16000. Note that import demand is given by M=m(1-t)Y. 1. What is the output gap?What effect do you think this federal government shutdown may have had on the Keynesian C + I + G + X curve? As part of your answer, make sure to address how each component of the curve is affected, as well as how APC, APS, MPC, MPS, and the multiplier contribute to the changes
- 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…Draw and properly label an AD-AS model to show Keynesian, intermediate, and neoclassical zones. Then briefly explain the level of unemployment, inflation and real gdp in each zone, and confirm wether all three goals of a macro economy are being achieved in each zone .Assume a Keynesian AS curve. In the short run, when there is a large negative output gap (AD-AS intersection far to the left of the full employment level of output), then 1.expansionary demand management policy is likely to be highly inflationary 2.expansionary demand management policy does not cause much inflation 3.the government should use contractionary demand management policy 4.contractionary demand management policy is likely to be highly inflationary
- 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.Pls help with below homwork. Explain and illustrate graphically the possible fiscal and monetary policy responses to a demand shock in the Keynesian model. What are the limitations of fiscal and monetary policy in the Keynesian model when a demand shock disturbs the economy?A principle difference between the new Classical and the new Keynesian models has to do with the choices made by business firms. We find that: a)new classical business firms choose the output level given the price level, while new Keynesian firms choose the price level given the level of output. b)new classical business firms choose the price level given the output level, while new Keynesian firms choose the output level given the level of output. c)both new classical and new Keynesian firms select the price level, but only new classical firms select the output level. d)both new classical and new Keynesian firms select the output level, but only Keynesian firms select the price level.
