Solution: CPI Increase = (165 - 150) / 150 = 0.10 or 10% Inflation Rate (Laspeyres) = CPI Increase × 100 = 10% × 100 = 11.11%

Solution: Paasche Price Index = (Current Year Expenditure / Base Year Expenditure) × 100 Current Year Expenditure = 120 units × $15 per unit = $1800 Base Year Expenditure = 100 units × $10 per unit = $1000 Paasche Price Index = ($1800 / $1000) × 100 = 180% Percentage Increase in Price Level = Paasche Price Index - 100 = 180% - 100% = 80%

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

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%

- 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
