IB Economics SL Internal Assessment Example

The student includes two relevant AD–AS diagrams that are accurately labelled and clearly tied to the commentary’s central argument.

The diagrams support the written analysis by showing both the supply-side effect of tariffs and the policy response through a shift in aggregate demand.

The visual presentation is economically clear, with the key axes, curves, and recessionary gap identified correctly.

There is a minor numbering inconsistency between the figure label and the in-text reference.

The second diagram’s outcome could be explained more precisely to show whether the economy fully returns to full employment or only narrows the gap.

The student uses a wide range of relevant macroeconomic terminology appropriately and in context.

Key terms such as expansionary monetary policy, recessionary gap, cyclical unemployment, consumer confidence, investment, and time lags are integrated into the explanation rather than listed mechanically.

The commentary generally maintains clear economic language and distinguishes policy transmission from the wider macroeconomic setting.

At one point, the discussion blurs SRAS and AD by implying that higher costs from tariffs directly cause less aggregate demand.

A few word choices could be made more technically precise to keep the language consistently professional.
