IB Economics HL Internal Assessment Example

Three relevant trade diagrams are included and they are accurately labelled.

The diagrams show the tariff effect clearly, including changes in price, output, consumption, and imports.

The final welfare-loss diagram is correctly used to support the argument about efficiency.

A fuller explanation of the diagrammatic movements would make the argument even stronger.

A few terms in the explanation are slightly imprecise, especially around world price versus domestic price.

Explicit titles and more conventional area labels would improve presentation.

A wide range of relevant economic terminology is used throughout the commentary.

The language is generally appropriate and clearly tied to the tariff and trade context.

Key terms such as tariff, world price, imports, consumer surplus, and welfare loss are used to build an economics-focused argument.

There are occasional imprecise uses of terminology, especially when the domestic price is described as the world price.

Some phrases are less conventional than standard economic terminology, such as 'community surplus'.

A few terms are used in a way that could be more precise to avoid confusion.
