ון רבSuip Reset the graph and click on the blue square to apply a negative supply shock the the economy. Then adjust the movable point to view the effects of potential policy responses to the negative supply shock. Use what you observe to answer the questions that follow. a. In response to the effects of a negative supply shock, policymakers decide to decrease aggregate demand. What are the effects of this choice? O an increase in aggregate output, and an increase in the aggregate price level an decrease in aggregate output, and an decrease in the aggregate price level an increase in aggregate output, and an decrease in the aggregate price level an decrease in aggregate output, and an increase in the aggregate price level b. What are the overall tradeoffs with regard to this choice? Policymakers have chosen to fight inflation by increasing AD, but this further reduces aggregate output and makes the recession worse. Policymakers have chosen to fight inflation by decreasing AD, but this…

Suppose an economy is in long-run equilibrium.a. Use the model of aggregate demand andaggregate supply to illustrate the initialequilibrium (call it point A). Be sure to includeboth short-run aggregate supply and long-runaggregate supply.b. The central bank raises the money supply by5 percent. Use your diagram to show whathappens to output and the price level as theeconomy moves from the initial equilibrium to thenew short-run equilibrium (call it point B).c. Now show the new long-run equilibrium (call itpoint C). What causes the economy to move frompoint B to point C?d. According to the sticky-wage theory of aggregatesupply, how do nominal wages at point Acompare with nominal wages at point B? How donominal wages at point A compare with nominalwages at point C?e. According to the sticky-wage theory of aggregatesupply, how do real wages at point A comparewith real wages at point B? How do real wages atpoint A compare with real wages at point C?f. Judging by the impact of the money…
Assume an economy is initially operating at the natural rate of output. a. Draw an AD-AS model. Label the initial equilibrium point as point A. Use the model to illustrate graphically the short-run effects on price and output when the world oil price suddenly increases. Label the new equilibrium as point B. b. What happens to inflation and unemployment in the short run? c. Label in your diagram the long-run equilibrium point if the economy recovers on its own. Name it Point C. d. What monetary policy should the Fed use to help the economy recover in the short run? Label the equilibrium point in your diagram if the Fed took the proposed action. Name it Point D.

3)Show and explain the effects of an increase in aggregate demand in the long-run and short-run by using AD–AScurves.2)Show and explain by using a graph, what will happen to the price level and real GDP if the quantity of moneyincreases and the increase is not anticipated; that is, the price level is not expected to change.1)By using aggregate demand (AD) and aggregate supply (AS) curves, show and explain the effects of ananticipated increase in money supply on macroeconomic equilibrium according to Rational ExpectationsHypothesis.

The left-hand Which of the following statements is tru about the diagrams above depicting the macroeconommy in both Keynesian and Classical frameworks and a change from AEo to AE* and ADo to AD*? a) The left-hand diagrams show the effect of an increase in Aggregare Expenditures (and Aggregate Demand), where the short-run Aggregate Supply is horizontal, meaning a constant products price level. b) The right hand diagrams show the effect of an increase in Aggregate Expenditrues (and Aggregate DEmand), where short-run Aggregate Supply is vertical (constant Aggregate Quantity Supplied). c) The left-hand diagrams illustrate the Keynesian range of the shor-run Aggregate Supply curve, where Keynesian expansionary policy does not cause any inflation and thus is very effective. d) The right-hand diagrams illustrate the Classical or Monetarist range of the short-run Aggregate Supply curve, where Keynesian expansionary policy is totally dissipated in…
Prompt We have been discussing major macroeconomic concepts like the ADAS Model and Fiscal Policy. This is an opportunity to apply that knowledge to a real-world scenario. Choose one of the following scenarios and identify whether it is an example of a recessionary economy or inflationary economy. Next, analyze possible Neoclassical solutions for it. Then, analyze possible Keynesian solutions for it. What would the impact on the economy be in the short-run? Long-run? Scenario 1: An increase in the unemployment rate to 7.4% has occurred. Inflation has increased causing a decline in consumer spending. Exports have declined by more than $4 billion. This has caused a decrease in GDP by 3.7%. Scenario 2: An increase in consumer and government spending has occurred. This has increased GDP by 4.4%. Currently, inflation rate has increased to 1.6%. Unemployment has remained at 5.5%. Scenario 3: An increase in the stock market by 26.5% has occurred. Companies are stockpiling the earnings…

1. Suppose that the oil price sharply increased for a while, which increased production costs, causing an adverse supply shock. A. Use the AD-AS model to show the effects on output and the price level in both the short- run and long-run. B. Show the adjustment process of the economy from the short-run to the long-run. C. What is the effect on unemployment in short-run and long-run? D. Can policymakers do something to accommodate this shock? Would the outcome be different in this case?
1.) The Keynesian AD-AS model describes what happens with price levels when aggregate demand increases. Could you find any evidence from the last ten-fifteen years that might support AD-AS model descriptions of demand-pull inflation, cost-push inflation, and recession? For example, you could find data on the GDP’s of any two countries from 2000 to 2017 to support your findings. 2.) In macroeconomics, the immediate short run is known as a length of time when both input prices and output prices are fixed. In the short-run, input prices are fixed but output prices are variable. In the long run, input prices and output prices can vary. What happens in the immediate short-run when AD falls from AD to AD2 to the price level and output? What happens in the short-run when AD falls from AD to AD2 to the price level and output? What will happen in the long-run?
5. Show how to derive the aggregate demand curve using the fixed-price Keynesian model.
