Papers: Ib Econ Past

She wrote her answer with cold precision. No waffle. Every sentence linked back to the text.

She grabbed a blank sheet of paper and set a timer for 45 minutes.

When the timer buzzed, her hand was cramped, but her confidence was not. She compared her answer to the markscheme. She had missed one key point: the role of cross-elasticity of demand for substitutes. A point lost, but a lesson learned.

It was three days before the final IB Economics exam, and Maya had a problem. Not a problem of supply and demand—though her anxiety was certainly spiking—but a problem of strategy. Her textbook was highlighted into a rainbow blur, her flashcards had fused together in a coffee spill, and her brain could define “allocative efficiency” in her sleep. But she knew, deep down, that knowing the definition wasn’t enough. The IB didn’t ask for definitions. It asked for application . Ib Econ Past Papers

Maya highlighted the article like a surgeon. She underlined: “Farmers are switching to durian production.” That was opportunity cost. “Global demand for robusta beans has surged.” That was a demand shifter. The calculation? 12% price increase, 8% quantity decrease. PED = -0.67. Inelastic.

She walked out of the exam hall into the spring sun. Two more papers to go. But she wasn’t worried. She had the archives on her side.

Then she wrote: “While demerit goods (e.g., cigarettes) generate negative consumption externalities, taxation is not always the optimal solution. If demand is inelastic, the tax may not reduce quantity significantly, and deadweight loss may be small, but the tax becomes regressive.” She cited a real-world example: Singapore’s high tobacco taxes versus the black market in e-cigarettes. She wrote her answer with cold precision

The first paper she pulled out was Paper 1, May 2023 (TZ2). The title alone sent a shiver down her spine. She remembered her teacher, Mr. Choudhury, saying, “The past paper is a mirror. It shows you what you actually know, not what you hope you know.”

So she did what any desperate HL student would do: she opened the creaking drawer of her desk, pulled out a thick, dog-eared folder, and began looking into IB Econ past papers.

Next, she pulled out Paper 2, November 2022. The insert was a news article about rising coffee prices in Vietnam due to a drought. The questions were brutal: calculate the PED, explain two supply-side factors, and evaluate the effectiveness of a price ceiling. She grabbed a blank sheet of paper and

She wrote steadily. Diagrams first. Then definitions. Then real-world examples: carbon taxes in Sweden, sugar taxes in Mexico. For evaluation, she used the “depends on” framework: “The effectiveness depends on the elasticity of demand, the presence of merit good alternatives, and the government’s ability to enforce the tax.”

She began to sketch. Demand and supply curves. A vertical wedge for the tax. The shrinking of consumer and producer surplus. And there it was—the Harberger triangle. Deadweight loss. Not just a term from a glossary, but a real loss of total welfare. She labeled everything: Pc for consumers, Pp for producers, Qt for quantity after tax, Qe for equilibrium.

At first, she froze. Her mind was a tangle of elasticities and externalities. But then she forced herself to look past the panic and look into the structure of the question. The command terms: “Explain” (10 marks) and “Evaluate” (15 marks). The hidden trap: students often forget that “always” is the keyword in part (b). The IB examiners loved an absolute.

By the end of the night, she had done three papers. Her room was a sea of diagrams, evaluation points, and examiner’s notes scribbled in red. But something had changed. The exam was no longer a monster hiding in the dark. It was a predictable machine. Paper 1 was always theory and evaluation. Paper 2 was data response and real-world application. Paper 3 (HL) was calculation and policy.
