- Suppose the economy of the hypothetical country “X” is currently in equilibrium at point A on thegraph. There were two major shocks to the economy in 2020.First shock was related to oil prices; the other was related to consumer confidence about futurebusiness conditions. Oil Shock: The economy X faced a rise in the average price of oil along with the rise of world price ofoil.E) Would an increase in oil prices cause a demand shock or a supply shock? Redraw the diagram toillustrate the effect of this shock by shifting the appropriate curve. What happens to theAggregate output and price level after the shock? (3)F) If policymakers wish to prevent the equilibrium output from changing in response to the oilprice increase, should they use contractionary or expansionary fiscal policy? (Redraw the graphfrom part E and show the change) (4)G) Even if the economy moves back to original Aggregate output, will there be any drawback? (1)Consumer Confidence Index: The Consumer Confidence Index…1. a) Construct the AD-AS model showing AD, short run AS and long run AS intersecting at the potential output level and label this intersection Eo. Assume that this represents the Philippine economy before the pandemic. b) From the initial condition, illustrate in your graph how the pandemic affected the economy in the short run (was there a demand shock or supply shock or both)? c) Explain the reason for the shift in the curve or curves? d) Explain how the changes in the AD-AS model above have affected equilibrium real GDP, unemployment, and price level.What, precisely, are the two shocks? (For the purpose of this question,let’s ignore the signifcant role played by the fnancial crisis itself.)
- Now suppose that droughts in the Southeast and floods in the Midwest substan-tially reduce food production in the United States. Suppose you are an economistworking for the Federal Reserve.d. Use the aggregate demand–aggregate supply model to illustrate graphically the im-pact in the short run and the long run of this adverse supply shock. Be sure to label:i. the axes; ii. the curves; iii. the initial equilibrium values; iv. the direction the curvesshift; v. the short-run equilibrium values; and vi. the long-run equilibrium values.State in words what happens to prices and output in the short run and the long run.e. Use the aggregate demand–aggregate supply model to illustrate graphically your pol-icy recommendation to accommodate this adverse supply shock, assuming that yourtop priority is maintaining full employment in the economy.f. Would you recommend the same policy if your top priority was maintaining the pricestability? Why?The imaginary country of Harris Island has theaggregate supply and aggregate demand curves as Table24.3 shows. a. Plot the AD/AS diagram. Identify theequilibrium.b. Would you expect unemployment in thiseconomy to be relatively high or low?c. Would you expect concern about inflation in thiseconomy to be relatively high or low?d. Imagine that consumers begin to lose confidenceabout the state of the economy, and so ADbecomes lower by 275 at every price level.Identify the new aggregate equilibrium.e. How will the shift in AD affect the originaloutput, price level, and employment?.SOlVE ONLY HIGHLIGHTED QUESTION Suppose we observe that US economy is experiencing low unemployment (3%), faster-than-average real GDP growth (4%), and increasing inflation (rising from 2% to 4%). a. Draw the AS/AD graph for the kind of shock that would generate these symptoms, and give an example of how that kind of shock might happen. What kind of change in the economy leads to this kind of AS/AD graph? b. Briefly discuss what you see in the graph that corresponds to each of the symptoms. E.g. what part of the picturetells you we have low unemployment? b)Describe the two goals that the Federal Reserve is required to pursue with monetary policy. Given these two goals, what specific actions will the Fed take in reaction to the shock, and how will these affect real GDP in the short run? Be sure to explain how the proposed action helps achieve the Fed's goals.
- The Covid-19 crisis and lockdown has been a supply-side shock to the South African economy. In response, the government offered a R500bn stimulus package to help cushion the blow. Use the AD-AS model, in conjunction with the IS-LM-BP, to explain the supply and demand dynamics of the shock and policy response. Where will equilibrium income and prices settle? Draw the graphs and explain the complete chain reaction, VuwaniAfrica @matenzhes Apr 22, 2020 ... Summary of RS00bn South Africa stimulus package: R200bn: Loan guarantee scheme R100bn: Jobs protection/creation R70bn: Tax relief R20bn: PPE R20bn: Municipalities RS0bn: Social grants R40bn: UIF (payment for layoffs) Ria livhuwa @CyrilRamaphosa,S09.,hello, I know for sure that answer "positive supply shock; LRAS to the right," is wrong. ?1) According to the Phillips Curve, as unemployment falls what happens to inflation? Why? 2) According to the Phillips Curve, as unemployment rises what happents to inflaiton? Why? 3) According to the Aggregate Supply/ Aggrgeate Demand model, if AD increases what happebs to Price Level GDP and Unemployment 4) Accroding to the AS/AD model, if AD decreases what happens to PL, GDP and unemployment? 5) According to the AS/AD model if AS decreases what happens to PL GDP and unemployment? 6) Based on your answer to #5 how would you show the decrease in AS on the Philips Curve?
- How does a credible nominal anchor help improve theeconomic outcomes that result from a positive aggregatedemand shock? How does a credible nominal anchorhelp if a negative aggregate supply shock occurs? Usegraphs of aggregate supply and demand to demonstrate.Countries like China and other developed economies are in the Neo dasmcal zone. What is the best option for these countries to sustain ther economies? a Increase aggregate supply b. Move back to Keynesian Zone c Move back to intermediate zone d. Decrease aggregate demand1. Using the AS-AD model, graph and explain the effects of Covid-19 on the U.S. macroeconomy by comparing 2019 vs. 2020. Label the years on all curves, the axis, and the equilibrium. Ignore macroeconomic policy responses, such as the CARES act. Which curves shifted which direction, and why? 2. Now introduce any macroeconomic policy response. What curves shift which direction, and why? 3. What were the equilibrium quantities for both axis?
