Suppose the price of a standard smartphone, a key item in the fixed basket of goods used to measure consumer prices, increases by 20% in one year. In that same year, the new standard model includes a significantly better camera, a faster processor, and longer battery life. Based on this information, what is the most accurate evaluation of how this price change affects the measurement of the cost of living?
Calculating Inflation in a Simplified Economy
An economist is tasked with creating a price index to measure the change in the cost of living for a typical urban family. Which of the following approaches best aligns with the methodology and purpose of the Consumer Price Index (CPI)?
Consider an economy where the following events occur simultaneously: (1) The price of imported coffee, a popular beverage, rises by 15%. (2) The price of domestically manufactured jet engines, sold to airplane manufacturers, falls by 10%. (3) The government increases the sales tax on clothing, which consumers pay at the point of purchase. Which of these events will be directly captured in the calculation of the Consumer Price Index (CPI) for that period?

CPI vs. Personal Cost of Living
In a simplified economy, the basket of goods used to measure consumer prices consists of only two items: Housing (which makes up 70% of a typical household's budget) and Movie Tickets (which make up 5% of the budget). In a given year, the price of housing increases by 2%, while the price of movie tickets increases by 20%. Which statement best describes the resulting change in the overall price index?
A major technological innovation makes solar panels significantly cheaper and more efficient. As a result, a large number of households switch from using natural gas for heating to using electricity generated by their new solar panels. The basket of goods used to measure consumer prices, which was last updated five years ago, gives a significant weight to natural gas but does not include residential solar panels. How would this shift in consumer spending patterns likely affect the accuracy of the price index as a measure of the change in the cost of living?
The Consumer Price Index (CPI) is designed to measure the change in the cost of a fixed basket of goods and services that a typical household consumes.

Calculating the Cost of a Fixed-Quantity Basket for CPI
An economist observes that a country's Consumer Price Index (CPI) was 150 in one year and rose to 159 in the following year. Based on this data, what was the country's inflation rate between the two years?
An economist is tasked with calculating the annual rate of price level change using a country's price index data for two consecutive years. Arrange the following actions into the correct sequence to complete this calculation.
Calculating and Interpreting Inflation
If a country's Consumer Price Index (CPI) is higher at the end of Year 3 than it was at the end of Year 2, and also higher at the end of Year 2 than at the end of Year 1, then the inflation rate must have been higher in Year 3 than it was in Year 2.
Explaining the Inflation Rate Calculation
A country's consumer price index was 100 in Year 1, 110 in Year 2, and 121 in Year 3. Based on this data, which of the following statements accurately describes the rate of price changes?
A country's price index was 120 in a given year. If the rate of price increase for the following year was exactly 5%, the price index for that following year would be ____.
Evaluating Economic Well-being Based on Inflation Data
Match each scenario describing a change in a country's consumer price index over a year to the correctly calculated annual inflation rate.
An economic analyst is comparing the change in a country's general price level over two separate one-year periods. In the first period, the price index rose from 120 to 132. In the second period, the price index rose from 150 to 162. Which of the following statements accurately compares the rate of price increase between these two periods?
