- 1 1A) Using the static AD/AS model to explain how the job keeper (wage subsidy) policy worked to sustain the economy even though unemployment rate in Australia had increased during Covid-19 period? 1B) justify in detail the difference between U shaped recoveries and V shaped recoveries?Two main macroeconomic concerns are the problems of inflation andunemployment.a. What are the social costs of inflation? Explain TWO of them? b. What is natural rate of unemployment? Explain the TWO main causesof natural rate of unemployment. With reference specifically to ONEof these causes, suggest ONE practical government policy that reducesthe natural rate of unemployment.4Consider a baseline long run equilibrium where output is 22 trillion dollars, and the price level is 100. Note: In the Long Run Steady State Equilibrium, Price expectation is the same as price level & unemployment is 5% or lower. None of these are guaranteed in the short run. Usually, short run equilibrium is called an underemployment equilibrium.Starting from the baseline, suppose COVID 19 hits this economy. If this disease only makes workers sick (everything else remaining constant) A Keynesian Macroeconomist proposes the use of a massive expansionary fiscal policy. Step 1) What will be the shape of the Phillips Curve (Upward / Downward/ Vertical/Horizontal). I want you to think about what variable is measured on the horizontal axis of the Phillips Curve Graph and what variable is measured in the Phillips Curve Vertical axis. Then tell us what it means to say that Phillips Curve is upward or downward sloping or vertical or horizontal Step 2) why did this policy create a…
- 2. Show a AD-AS graph inflation in the short run and the shift in the SAS necessary to eliminate it.The CPI tracks the average change in prices of a basket of goods and services overtime, whereas the UNRATE is the percentage of the labour force that is unemployed.By examining the cointegration between these two variables, you can gain insightsinto the relationship between inflation and unemployment in the US economy. Thequarterly series is complete and seasonally adjusted. a) From a theoretical perspective, are these two series expected to becointegrated? Justify your answer. b)How do expectations about future economic conditions influence the speed ofadjustment? Are there any other factors that might affect the speed of adjustment?Suppose Chino is a closed economy. A large portion of the work force has joint astrong labor union. As such, the nominal wages of most workers are downwardrigid.Suppose most households lose their wealth in a recent clash of the stock market.How would the price and output level of Chino be affected in the short run?Explain by using the AD-AS model. Particularly, use the sticky-wage model ofaggregate supply to explain the magnitude of the effects on price and output.
- a) If a country's natural unemployment rate is 5.5 percent and its actual unemployment rate is 3.5 percent, what is its cyclical unemployment rate? ___________percent Instructions: Enter the value for the output gap as an absolute number. b) According to Okun's law, this country would have (Click to select) a recessionary an expansionary output gap of _________percent.Suppose, initially the Australian economy is atfull employment(in other words the economy is atthe potentialGDP). Using AD-AS model, explain how would each of the following events aectthe economy both in theimmediate and in the long term.a) A slowdown in China’s economic growth due to the sub-prime crisis in the US.b) Union wage settlements push the wage rate up.c) An increase in consumer confidence.Aggregate demand functionwas Y=3300-3P last year, current year it looks likeY=3390-3P. SRAS curve is horizontal. Potential GDP is $3000 bln and it hasn'tchanged.Find out equilibrium GDP in the short-run and inflation rate in the long-run.Using AD-AS model illustrate the task.
