IB Economics SL Internal Assessment Example

The student included two relevant, correctly connected diagrams that clearly show the market before and after the tariff change.

The diagrams are generally well labelled and communicate the direction of price, output, and import changes effectively.

Some of the welfare-area labels and references in the student's written explanation are imprecise or misassigned.

The explanation would be stronger if every shaded area were matched explicitly to the correct economic measure.

The student uses a good range of relevant economic terms such as tariff, protectionism, world price, domestic demand, domestic supply, consumer surplus, and producer surplus.

The student's terminology is often linked to the article and helps keep the commentary focused on trade policy.

The student sometimes uses key terms inaccurately, especially when describing the import gap as a shortage.

The student treats the tariff as if it changes the world price, which weakens the precision of their economic language.
