Comment: The student included a relevant diagram of the chosen concept and topic. Figure 1 shows the negative externality diagram related to carbon emissions, showing the difference between marginal social and private costs. Since this is microeconomics, the student made a good decision in choosing an externality diagram to illustrate the impact of carbon emissions on South African society. The diagram also captured why there was a need for a carbon tax as highlighted in the article.

Comment: The diagrams included are labeled and illustrate the economic concepts discussed. The negative externality diagram shows the relationship between marginal social cost and marginal private cost, helping to visualize the welfare loss. The student made the diagram accurate by adding the price/cost/benefit (y-axis) of the diagram in currency (Rand) mentioned in the article. The distance between MSC1 and MSC2 also has shown the key concept of 'change' as a shift, which is illustrated if the carbon tax were implemented accordingly. The shift closer to MSC1 and not closing the gap also displayed the full understanding of the article since the carbon tax had to be implemented in phases to realistically reduce the negative externality.

Comment: The student includes diagrams in the IA, each with a clear explanation. For example, Figure 1 illustrates the negative externality and welfare loss associated with carbon emissions, enhancing the reader's understanding of the economic concepts discussed. In the highlighted parts, the student clearly explained why a negative externality existed here (about the article). The student also established how a tax implementation could reduce the losses.

Comment: The student correctly uses subject-specific terminology relevant to the chosen article and the key concept of sustainability. Terms such as carbon tax, negative production externality, and marginal social cost are utilized. The student demonstrates an understanding of these concepts in their analysis, particularly in discussing the implications of the carbon tax on firms and society. The use of diagrams illustrates the student’s comprehension of the economic principles involved. Though not required, the student defined negative production externality and welfare loss at the beginning of the commentary. This is okay however, the correct and consistent use of these terms throughout the essay allowed the student to showcase an understanding of the terms used for the commentary.

Comment: The student incorporates subject-specific terminology throughout the commentary. Terms such as "negative production externality," "Carbon tax," "marginal social cost," and "welfare loss" are used accurately to discuss the implications of the carbon tax policy. It is important to remember to stick to the area of the syllabus to which the commentary is about - Microeconomics.
