In Tutorial 4 we discussed what impact Covid-19 would have upon output in a simple Keynesian model. In this question, we extend this analysis by examining the impact of Covid-19 in the context of the AD-AS model.
a) Suppose Covid-19 reduces the exogenous component of consumption (C), planned investment, IP and exports X. What impact will this have upon the position of our AD andAS curves. Explain your reasoning by using a diagram.
b) Explain how the macroeconomy would adjust to the Covid-19 shock (as described above) in the long run if there was no change in the monetary policy reaction function or fiscal policy in response to the pandemic. Explain your reasoning using a diagram.
c) In response to the pandemic, the government has pursued a policy of increasing payments to unemployed individuals (ie. Jobkeeper). In addition, it has foreshadowed a reduction in taxes in the October budget update. Explain what impact these policies will have upon the macroeconomy with reference to the AD-AS model.
