(a) As a response to the recent COVID-19 outbreak, the Commonwealth Government put in place lockdown restrictions. Using the dynamic AD-AS framework, analyse and demonstrate the impact of the COVID-19 pandemic on the level of output (or real GDP), unemployment, and inflation.
(b) In response to the COVID-19 pandemic, in March 2020 the Commonwealth Government announced a fiscal stimulus which included income support for workers and businesses hit by the pandemic. Using the same dynamic AD-AS framework used in part (a), explain and illustrate the effect of the fiscal stimulus on the level of output (or real GDP), unemployment, and inflation.
(c) Using the same dynamic AD-AS framework used in part (b), show what the impact of the fiscal stimulus would have been if Australia had no interactions in trade or finance with other economies (i.e. if Australia was a closed economy).
Within the Keynesian model with both a flexible price and flexible money wage, illustrate graphically and explain the effect of a decline in expectations. Include in your answer the effects of this policy shift on real output, the price level, employment, the money wage, and the interest rate. Explain what this question has to do with the typical Keynesian view of what causes recessions.
Consider a standard AD-AS model.
The economy is affected by the following sequence of events. In period 1 there is a shock to the economy that is temporary. In period 2, the shock ends. But having observed an inflation outcome different to the inflation target, inflation expectations change from the inflation target to a value exactly equal to the observed inflation in period 1 (that is, expectations are not `anchored’).
A temporary positive demand shock would lead to output above potential in period 1, but below potential in period 2.
Answer true or false. Please briefly explain your answer.

- Two potential causes of inflation above target in the AD-AS model: Demand-pull inflation: This occurs when aggregate demand (AD) increases more than the long-run aggregate supply (LRAS). In the AD-AS diagram, this would be represented by a rightward shift of the AD curve. The result is a higher price level and real GDP beyond the long-run macroeconomic equilibrium level. Cost-push inflation: This occurs when the short-run aggregate supply (SRAS) curve shifts to the left due to increased production costs, such as rising wages or input prices. In the AD-AS diagram, this would be represented by a leftward shift of the SRAS curve. The result is a higher price level and a reduction in real GDP. how do i graph this information in an ad-as diagramarrow_forwardConsider a standard AD-AS model.

- 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.arrow_forwardFigure 1: Hayek’s (Classical) AD-AS Model Economics Online.

- Please note I only need help with Part 4 and 5. I have answers for the other parts. Thank you so much for your time and effort! Figure 2: Keynes’s AD-AS Model (Image normally goes here) Part 1:Changes in which factors could cause aggregate demand to shift from AD to AD1? What could happen to the unemployment rate? What could happen to the inflation rate? Part 2: 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. Please note the followong for the next 3 parts of this.

- Consider the AD-AS model below. The economy is in long-run equilibrium at point in period 1. Consider an increase in government spending. If the public has rational expectations, the economy will move to point If the public has adaptive expectations, the economy will move to point . In period 3 the AS will pass through point In the long run the AS will move to pointarrow_forwardb) There is a change in expectations and firms in the economy now expect the price level to be lower in the future. In the context of the AS-AD model, and with the aid of a diagram, explain the short run effects this has on the price level output, and unemployment in the economy.arrow_forwardUse a standard dynamic AS-AD model to explain how the macroeconomy adjusts following a favourable supply shock (vt < 0) for one period which reverts to zero for all subsequent periods. Assume that the economy starts from its long-run equilibrium. As a reminder, the DAD and DAS curves, respectively, are provided below: Y =Y - αθη 1+aly Tt = t_1+ ¢(Y - Y)+v where Y is output, πt is inflation, 0 and Oy capture the responsiveness of the central bank to inflation and output, a is the sensitivity of output to the real interest rate and is the sensitivity of inflation to the output gap.
