Weighting of Items in the CPI Basket
To ensure the Consumer Price Index accurately reflects household spending, each good and service in the representative basket is weighted. This weight corresponds to the proportion of a typical household's budget that is spent on that particular item.

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.

An economy experiences several events over a year. Which of the following events represents an expenditure that is not included when calculating the total planned expenditure, also known as aggregate demand?
A country's price index is calculated using a basket of goods. The table below shows the main categories in the basket, the percentage of a typical household's budget spent on each (its weight), and the price change for each category over the past year.
Category Expenditure Weight Price Change Housing 40% +5% Transportation 15% +20% Entertainment 5% +30% Food 25% +4% Based on this data, which category's price change contributed the most to the overall increase in the price index?

Volatility of Expenditure Components
A national statistics agency reports that the average price of housing increased by 5% last year, while the average price of table salt increased by 50%. A media commentator argues that the sharp rise in the price of salt was the more significant factor driving up the overall cost of living for the typical household. Which of the following statements best evaluates the commentator's argument?

A monetary union of several African nations uses a currency that is maintained at a constant, fixed value against the euro. If the euro experiences a significant appreciation against the U.S. dollar, what is the most likely impact on the value of the African nations' currency relative to the U.S. dollar?
Inflation Dynamics under a Currency Peg
Suppose that retired individuals spend a much larger proportion of their income on healthcare than the average household. If the price of healthcare services increases by 10% while all other prices remain constant, how would the change in the cost of living for retirees compare to the change in the official, nationally-calculated price index?
