5. In 2022, the average price of a car was $25,000, and in 2023, it increased to $28,000. If the inflation rate for the period was 5%, what was the real price change of the car from 2022 to 2023? A) $3,000 B) $2,500 C) $2,000 D) $1,750

Solution: Real Price Change = Nominal Price Change - Inflation Rate Nominal Price Change = $28,000 - $25,000 = $3,000 Real Price Change = $3,000 - (5% × $25,000) = $3,000 - $1,250 = $1,750

Answer: D

Solution: CPI Increase = (220 - 200) / 200 = 0.10 or 10% Inflation Rate (Paasche) = CPI Increase × 100 = 10% × 100 = 10%

Answer: C

7. The GDP deflator for a country in 2020 was 110, and in 2021, it was 105. Calculate the disinflation rate for the period. A) 4.55% B) 4.76% C) 4.17% D) 5%

Solution: Disinflation Rate = (GDP Deflator in Earlier Year - GDP Deflator in Later Year) / GDP Deflator in Earlier Year × 100 Disinflation Rate = (110 - 105) / 110 × 100 ≈ 4.55%

Answer: A

8. The Producer Price Index (PPI) for a set of goods in the base year was 140. In the current year, the PPI for the same goods decreased to 120. What is the percentage change in the producer prices? A) -14.29% B) -16.67% C) 14.29% D) 16.67%

Solution: Percentage Change = [(Current PPI - Base PPI) / Base PPI] × 100 Percentage Change = [(120 - 140) / 140] × 100 ≈ -14.29%

Answer: A

9. In 2022, the average salary for a profession was $60,000, and in 2023, it increased to $68,000. The CPI for 2022 was 180, and for 2023, it was 190. Calculate the real wage change between 2022 and 2023. A) $4,000 increase B) $6,000 increase C) $2,456 increase D) $8,000 increase

Solution: Real Wage Change = (Nominal Wage / CPI) * 100 (From 2022 to 2023) Real Wage Change = ($68,000 / 190) * 100 - ($60,000 / 180) * 100 Real Wage Change = $35,789 - $33,333 ≈ $2,456

Answer: C

10. A country experienced an inflation rate of 6% last year and 12% this year. If the inflation rate follows a geometric progression, what will be the inflation rate for next year? A) 10% B) 12% C) 15% D) 9%

Solution: Geometric Mean = √(Inflation Rate of Last Year × Inflation Rate of This Year) Geometric Mean = √(6% × 12%) = √(0.06 × 0.12) ≈ 0.09 or 9%
