Paper labels are an unofficial, independently authored grouping, applied only where a question's own format genuinely matches a real paper convention (such as IB Mathematics AA's non-calculator/calculator split). They do not reproduce any exam board's real paper numbering or mark allocation, and uncertain questions are labelled general practice instead.
1 The government of a small country imposes a specific tax of $2 per unit on sales of sugary drinks, a good with relatively price-inelastic demand. (a) Explain, describing the demand curve in words, why inelastic demand means most of the tax burden is likely to fall on consumers rather than producers. (b) State the likely effect of this tax on government tax revenue. (c) Explain one reason a government might choose to tax a good with inelastic demand specifically to raise revenue. Paper 1 style Medium 4 marks No calculator + 2 Marking analysis: A learner attempts the following task: “The government of a small country imposes a specific tax of $2 per unit on sales of sugary drinks, a good with relatively price-inelastic demand. (a) Explain, describing the demand curve in words, why inelastic demand means most of the tax burden is likely to fall on consumers rather than producers. (b) State the likely effect of this tax on government tax revenue. (c) Explain one reason a government might choose to tax a good with inelastic demand specifically to raise revenue.” Their response addresses only this point: “States that with inelastic demand, quantity demanded changes proportionally less than price.” Evaluate the response against the complete 4-mark task. Identify what earns credit and state every additional requirement needed for full marks. Marking analysis Medium 4 marks No calculator + 5 When the price of a particular smartphone model rose from $600 to $660, the quantity demanded fell from 5,000 to 4,200 units per month. (a) Calculate the price elasticity of demand using the percentage change method. (b) State whether demand is elastic, inelastic or unit elastic. (c) Calculate the resulting percentage change in total revenue. (d) State whether the manufacturer's total revenue increased or decreased as a result of the price rise. Paper 2 style Medium 5 marks Calculator + 6 Marking analysis: A learner attempts the following task: “When the price of a particular smartphone model rose from $600 to $660, the quantity demanded fell from 5,000 to 4,200 units per month. (a) Calculate the price elasticity of demand using the percentage change method. (b) State whether demand is elastic, inelastic or unit elastic. (c) Calculate the resulting percentage change in total revenue. (d) State whether the manufacturer's total revenue increased or decreased as a result of the price rise.” Their response addresses only this point: “Calculates the percentage change in quantity as −16% (from 5,000 to 4,200).” Evaluate the response against the complete 5-mark task. Identify what earns credit and state every additional requirement needed for full marks. Marking analysis Medium 5 marks No calculator + Self-assessed 0 / 0
