Understanding Consumer Price Index (CPI)

This video tutorial by Mr. Clifford covers the key economic concept of the Consumer Price Index (CPI). It explains the role of the Market Basket in measuring inflation and demonstrates how to calculate CPI using different base years. The tutorial includes examples and practice exercises to help viewers understand how price changes affect consumers over time.

What is the primary purpose of the Consumer Price Index (CPI)?

• To track changes in the cost of living over time

• To measure the economic growth of a country

• To determine the unemployment rate

• To calculate the GDP of a nation

What does a Market Basket represent in the context of CPI?

• A set of goods and services used to measure inflation

• A list of government policies

• A collection of stocks and bonds

• A group of economic indicators

If the CPI is 200 in 2010 with 2009 as the base year, what does this indicate?

• Prices have decreased by 50%

• Prices have remained the same

• Prices have increased by 20%

• Prices have doubled since 2009

How do you calculate the CPI for a given year?

• Subtract the inflation rate from the base year

• Divide the GDP of the year by the base year

• Divide the cost of the Market Basket in the given year by the cost in the base year and multiply by 100

• Multiply the unemployment rate by 100

When switching the base year to 2010, what happens if the CPI is less than 100?

• Prices have doubled since 2010

• Prices have remained constant

• Prices have decreased since 2010

• Prices have increased since 2010

What does a CPI of 125 indicate when 2010 is the base year?

• Prices have decreased by 25%

• Prices have remained the same

• Prices have increased by 25%

• Prices have doubled

If the CPI is 80 with 2011 as the base year, what does this mean?

• Prices have remained the same

• Prices are 20% higher than in 2011

• Prices are 20% lower than in 2011

• Prices have doubled since 2011

What is the significance of a CPI value of 40 when 2011 is the base year?

• Prices have doubled since 2011

• Prices have remained the same

• Prices are 60% higher than in 2011

• Prices are 60% lower than in 2011

In the practice exercise, if the Market Basket in 2010 is $50 and the CPI is 125, what was the cost in the base year?

• $50

• $30

• $60

• $40

What is the first step in calculating the CPI for a new base year?

• Determine the GDP of the new base year

• Identify the cost of the Market Basket in the new base year

• Calculate the unemployment rate

• Find the inflation rate
