Understanding CPI and Inflation Rates

This video tutorial explains how to calculate the Consumer Price Index (CPI) and the inflation rate. It begins with an introduction to the CPI, a measure of the overall cost of goods purchased by urban consumers, and its role in calculating inflation. The video presents the formula for the annual inflation rate, which is the percentage change in the CPI from the previous year. A simple economy example with three goods is used to demonstrate the calculation of the fixed basket costs for different years. The tutorial then shows how to construct the CPI index using these costs and concludes with the calculation of annual inflation rates for 2017 and 2018.

What does the CPI-U measure?

• The overall cost of goods purchased by urban consumers

• The average income of urban consumers

• The cost of goods in rural areas

• The total number of goods produced in a year

How is the annual inflation rate calculated?

• By dividing the GDP of two consecutive years

• By subtracting the CPI of the base year from the current year

• By calculating the percentage change in CPI from the previous year

• By adding the CPI values of two consecutive years

In the simple economy example, which data is only needed for the base year?

• GDP values

• Quantities of goods

• Prices of goods

• Inflation rates

What remains constant in the fixed basket calculation?

• Prices of goods

• Quantities of goods

• Inflation rates

• CPI values

How is the CPI for a given year calculated?

• By adding the costs of all goods in the current year

• By dividing the cost of the fixed basket by the base year cost

• By multiplying the base year cost by the current year cost

• By dividing the GDP by the total population

What is the CPI value for the base year always set to?

• 50

• 200

• 100

• 150

What was the CPI in 2017?

• 124.8

• 100

• 113.2

• 150

What was the inflation rate in 2017?

• 15%

• 10.25%

• 20%

• 13.2%

How is the inflation rate for a year determined?

• By adding the CPI values of the current and previous years

• By dividing the CPI of the current year by the previous year

• By calculating the percentage change in CPI from the previous year

• By subtracting the GDP of the previous year

What was the inflation rate in 2018?

• 20%

• 15%

• 13.2%

• 10.25%
