Question #1
Fisher's ideal index satisfies the factor reversal test because:
A. Its price and quantity index product equals the value index
B. It ignores quantity changes
C. It uses base period weights
D. It is the arithmetic mean of Laspeyres and Paasche

Correct Answer: Option A


Explanation:
Fisher's index is designed so that (Fisher price index) × (Fisher quantity index) = Σp₁q₁/Σp₀q₀ (value index), fulfilling the factor reversal test for consistency between price and quantity measures.

Question #2
Paasche price index is calculated as:
A. Σ(p₁q₀)/Σ(p₀q₀) × 100
B. Σ(p₁q₁)/Σ(p₀q₀) × 100
C. Σ(p₁q₁)/Σ(p₀q₁) × 100
D. √[Σ(p₁q₀)/Σ(p₀q₀) × Σ(p₁q₁)/Σ(p₀q₁)] × 100

Correct Answer: Option C


Explanation:
Paasche index = Σ(p₁q₁)/Σ(p₀q₁) × 100, using current period quantities (q₁) as weights, which may understate inflation due to substitution effects but reflects current consumption patterns.
