Difficulty: EasyOutput (Value Added) Method of Measurement

Match each stage of production in a leather shoe manufacturing process with its correct Value Added contribution to National Income.

  • Cattle Ranching (Raw hides sold for ₦4,000; Intermediate inputs = ₦0)Value Added = ₦4,000
  • Leather Tanning (Tanned leather sold for ₦10,000; Purchases raw hides for ₦4,000)Value Added = ₦6,000
  • Shoe Manufacturing (Shoes sold to retailer for ₦18,000; Purchases tanned leather for ₦10,000)Value Added = ₦8,000
  • Retail Distribution (Shoes sold to consumer for ₦25,000; Purchases shoes for ₦18,000)Value Added = ₦7,000

Answer

Cattle Ranching matches Value Added = ₦4,000; Leather Tanning matches Value Added = ₦6,000; Shoe Manufacturing matches Value Added = ₦8,000; Retail Distribution matches Value Added = ₦7,000.
Each stage's contribution to national income is determined by subtracting the value of intermediate inputs purchased from the value of gross output generated at that specific stage.

Step-by-Step Solution

1
Calculate Value Added for Cattle Ranching
Value Added = ₦4,000 - ₦0 = ₦4,000
Value added is calculated as Gross Output minus Intermediate Inputs.
2
Calculate Value Added for Leather Tanning
Value Added = ₦10,000 - ₦4,000 = ₦6,000
Subtract the cost of raw hides from the selling price of tanned leather.
3
Calculate Value Added for Shoe Manufacturing
Value Added = ₦18,000 - ₦10,000 = ₦8,000
Subtract the cost of tanned leather from the wholesale price of shoes.
4
Calculate Value Added for Retail Distribution
Value Added = ₦25,000 - ₦18,000 = ₦7,000
Subtract the wholesale price of shoes from the final retail price.

Key Concept

The Output (Value Added) Method calculates National Income by summing the net value added at each production stage (Gross Output minus Intermediate Consumption) to avoid double counting.
