Causes and Impact of the 2021-2022 Global Inflation Surge

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?

Evaluating a Price Index's Accuracy

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.
