IB Economics HL Internal Assessment Example

Relevant diagrams are included and they follow the basic tariff/free-trade structure clearly.

The diagrams use appropriate market labelling, including price, quantity, and import references.

The free-trade diagram is broadly accurate and helps set up the policy change well.

The tariff diagram contains inaccuracies in the tariff amount and welfare-area identification.

The explanation of the welfare losses does not fully match standard tariff analysis.

The diagram work is relevant, but accuracy and precision are not yet fully secure.

The student uses a wide range of economic terminology accurately and naturally.

Key terms such as tariff, protectionism, world price, consumer surplus, producer surplus, and tariff revenue are integrated into the argument.

Technical language is often used to support reasoning rather than just being listed or defined.

A few phrases could be more precise, especially when discussing self-sufficiency and welfare impacts.

Some terminology is linked to the wrong welfare interpretation in the tariff diagram discussion.

Precision would improve if the student distinguished more carefully between redistribution and net welfare loss.
