The correct option is They are intermediate goods and their value is already included in the final good.
Explanation
Gross Domestic Product (GDP) is defined as the total monetary value of all final goods and services produced within the domestic territory of a country during a specific time period. A fundamental principle in National Income Accounting is the distinction between intermediate goods and final goods to ensure accurate estimation of economic activity.
Analysis
The exclusion of intermediate goods like wheat and flour when the final good (biscuit) is included is based on the following logic:
- Definition of Intermediate Goods: These are goods used as inputs in the production process to create another good. In this case, wheat is processed into flour, and flour is processed into biscuits.
- Embedded Value: The market price of the final good (the biscuit) naturally encompasses the costs of all raw materials (wheat, flour, sugar, fuel) and services used to produce it.
- Problem of Double Counting: If the value of wheat, flour, and the biscuit were all added to the GDP separately, the value of the wheat would be counted multiple times (once as raw wheat, again as part of the flour, and a third time as part of the biscuit). This would result in an artificially inflated GDP figure.
- Resolution: To avoid this error, national income accountants either count only the value of the final good or sum the value added at each stage of production, but never both.
They are agricultural products while biscuits are industrial is incorrect: The sector of origin (agriculture vs. industry) does not determine whether a good is counted; its usage as an input or final product does.
The prices of wheat and flour fluctuate significantly is incorrect: Price fluctuations are a market phenomenon but do not influence the structural methodology of avoiding double counting.
Biscuits are taxed commodities while wheat is not is incorrect: Tax status is irrelevant to the definition of intermediate versus final goods in the context of GDP calculation.
Key Takeaway: GDP calculations strictly include only final goods and services to prevent double counting, as the value of intermediate goods is already absorbed into the price of the final product.
