IB Economics HL 3.2.7 Comparing macroeconomic models Question Bank

Answers may include:
- definitions of inflation, inflationary, aggregate demand (AD), monetarist/new classical model, Keynesian model
- diagrams to show the impact of an increase in AD in the two different models
- explanation why in the monetarist/new classical model an increase in AD will be inflationary
- examples of cases where an increase in AD either has or has not been inflationary
- synthesis and evaluation (discuss).

Discussion may include: consideration of an increase in AD not being inflationary in the Keynesian model if the economy is operating with spare capacity, consideration of an increase in AD not being inflationary in the monetarist/new classical model if the economy is recovering from equilibrium below the full employment level of output, consideration of the impact of simultaneous improvements on the supply side of the economy as AD increases, a consideration of the word "inevitably", a consideration of the word "inflationary" in the context of the AD/AS model.

Marking guidance:
Award a maximum of level 2 if the response considers either the monetarist/new classical model or the Keynesian model (but not both).

Opinions or conclusions should be presented clearly and should be supported by appropriate examples.

Examiners should be aware that candidates may take a different approach which, if appropriate, should be rewarded.
