The worked question on this page is original educational practice. It is not represented as a question from an official previous-year examination paper.
01 / UNDERSTANDING
Review the question
Write an original production-chain problem that includes a tempting but double-counted gross-sales answer. Include gross sales as a tempting answer that counts the same grain repeatedly. An original checkpoint is: What is the mill’s value added in the example? Supported answer: 30 units. Explain the decisive fact, then alter one condition and solve again. This is an original practice method, not a claim that the question appeared in an official past paper.
02 / UNDERSTANDING
The concept in context
GDP and GVA comparisons require attention to valuation conventions, including the relevant treatment of product taxes and subsidies. A useful study check is to map the production chain and intermediate inputs, then reconcile total value added with final output. Explain why the method fits the stated facts before applying it to a changed situation.
03 / UNDERSTANDING
A worked learning case
A farmer sells grain for 40 to a mill, which sells flour for 70 to a bakery. The bakery sells bread to final buyers for 100. Assuming no other intermediate inputs, value added is 40 at the farm, 30 at the mill and 30 at the bakery. Their sum is 100, matching final output rather than gross sales of 210.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
What is the mill’s value added in the example?
Show the answer and reasoning
30 units.
The mill’s output is valued at 70, and its intermediate grain purchase costs 40. Subtracting the intermediate input gives value added of 30. Adding the entire 70 to the farm’s 40 without adjustment would count the grain’s value twice. The calculation uses the deliberately simplified input assumptions in the example.
Two traps to watch for.
- Adding intermediate sales to final output without adjustment.
- Comparing differently valued GDP and GVA measures as identical totals.
