Sample Questions
Which of the following are characteristics of Laspeyres' Index? (Select all correct answers)
Show answer
Uses base year quantities as weights, Formula: Σp₁Q₀/Σp₀Q₀ × 100, May overestimate cost of living changes
Laspeyres' Index uses base year quantities (Q₀) as fixed weights. The formula is Σp₁Q₀/Σp₀Q₀ × 100. It tends to overestimate price changes because it doesn't account for substitution effects. It does not satisfy the time reversal test.
Calculate Laspeyres' price index for the data: Item A: p₀=₹10, p₁=₹12, q₀=5 units; Item B: p₀=₹20, p₁=₹25, q₀=3 units.
If Fisher's Ideal Index is 115 and Laspeyres' Index is 120, what is Paasche's Index?
Which of the following statements about time series components are correct? (Select all that apply)
Show answer
Secular trend shows long-term direction, Seasonal component repeats within a year, Cyclical component has periods longer than a year
Secular trend shows long-term movement. Seasonal patterns repeat annually. Cyclical patterns have periods > 1 year. Irregular components are random and unpredictable. Mathematical techniques can decompose time series into these components.
