Using the AD-AS model (short-run and long-run AS) and the Aggregate Expenditure (AE) model and assuming the Singapore economy was at the natural rate of output at the onset of the crisis:

• Illustrate the impact of the crisis on the domestic economy using both the AD-AS model and the AE model. Ensure you clearly label all parts of the diagram, clearly demonstrating the original equilibrium and the COVID-19 outcome equilibrium.
• Discuss your rationale for the outcome you have demonstrated in your diagrams, ie discuss which components of AD/AS/AE have been affected and why - the basis of the shifts you demonstrated in the diagrams.

The 2 models you have used have different underlying assumptions.

• Outline the major underlying difference(s) between the two models.
• Briefly discuss and illustrate how the how the difference(s) in the model assumptions impact the degree of the potential impact on the economy. Use the AD-AS Model and provide ONE diagram to illustrate the potential difference in outcomes depending on the assumptions made. (Hint - consider the assumptions underlying the AE model - what SRAS curve reflects this?)
