In the Keynesian framework, which of the following events might cause a recession? Which might cause inflation? Sketch AD/AS diagrams to illustrate your answers. A large Increase In the price of the homes people own. Rapid growth in the economy of a major trading partner. The development of a major new technology offers profitable opportunities for business. The Interest rate rises. The good imported from a major trading partner become much less expensive.
The short run aggregate supply curve was constructed assuming that as the price of outputs increases, the puce of inputs stays the same. How would an increase in the prices of important inputs, like energy, affect aggregate supply?
In the AD/AS model, what prevents the economy from achieving equilibrium at potential output?
If the economy goes into a recessionary gap, a.) How will the change in wages affect short run AS and why?b.) As short run AS adjusts, what will happen to price level P and spending for output AD?c.) When will the adjustments in the labor market, wages, and AS stop and why?
09. 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…
Supply shocks and demand management Assume that the economy starts at a natural level if output. now suppose thee is an increase in the price of oil. a) In a AS-AD diagram show what happens to output and the price level in the short run and the medium run b) what happens to the unemployment rate in the short run? in the medium run?
3 . An economy experiences an adverse supply shock. a) Draw an AD-AS diagram to illustrate the effect of the shock. Be sure to include the LRAS line. b) What happens to output in the short run? What form of output gap (positive or negative) is formed? What happens to the aggregate price level in the short run? c) How will the long run equilibrium be restored? (Assume there is no fiscal and no monetary policy to help the process.) Explain and add this to your diagram. d) Does the process create inflation or deflation?
No written by hand solution An economist needs to predict the real wage rate, employment, output, real interest rate, consumption, investment, and price level. The economy is hit with a shock, which the economist thinks is a temporary adverse supply shock. (a) If you were the economist, what would be your forecasts for each of the variables listed above (rise, fall, and no change) in general equilibrium? (b) What if the shock was due to people's reduced expectations about their future income? Which variables did you forecast correctly, and which did you forecast incorrectly in part (a)?
1. Use the AD-AS model attached to explain and illustrate the difference between demand side measures and supply side measures and give an example of each. Also mention which markets are embedded within each curve. 2. Use the AD-AS model to Analyze and illustrate the short run impact of an increase in energy prices on GDP, inflation and employment. Which type of inflation is this?
5. Suppose an economy is hit by a flood and its natural resources decreases. a) Show graphically using AD-AS model how the price level and output are affected in the short-run. b) Can the government use monetary policy to offset the effects on price level and output, explain?
2. Show a AD-AS graph inflation in the short run and the shift in the SAS necessary to eliminate it.
a. What are the short-run equilibrium real GDP and price level in 2019?b. What is the long-run equilibrium real GDP?c. Is the short-run macroeconomic equilibrium a full-employment equilibrium, belowfull-employment equilibrium, or above full-employment equilibrium?d. In transition to the long run, how would the wages in this economy change?e. Following from d, explain how would the short run supply curve move to its long runposition, as the changes in the nominal wages take effect.f. What will the long run price level be?
