IB Economics HL Internal Assessment Example

Multiple relevant diagrams are included and each is accurate, clearly labelled, and directly tied to the economics being discussed.

The visuals do more than decorate the work: they show the market failure, policy intervention, macro transmission mechanism, and tariff welfare effects in a way that supports the argument.

Diagram explanations are generally full and accurate, with clear links between the graphical changes and the article evidence.

A few explanations could be even more explicit in naming individual curves, shifts, and welfare areas.

In one place, the written explanation cuts off before the full mechanism is completed, so the reader has to infer part of the policy effect.

A small refinement would be to distinguish more carefully between the welfare loss caused by the original market failure and the effects of the intervention itself.

Relevant economic terminology is used appropriately throughout the commentary.

Precise terms such as negative externality of consumption, social optimum, cost-push inflation, AD, SRAS, tariff revenue, and consumer surplus are applied in context.

The terminology helps the commentary remain economically grounded and supports the analytical argument.

There are a few imprecise formulations that would benefit from tighter economic language.

Some trade language could be made more precise, especially where interdependence is discussed alongside dumping and unfair competition.

A small number of explanations would be stronger if the terms were used with slightly more exact causal meaning.
