Question

John is creating a presentation on the consumer price index, for his business class. He wants students to understand that food and energy prices have risen more rapidly than other market items that the government traditionally measures for inclusion in the CPI calculation. He will show students that the core inflation figure will be _______ than the CPI. He will then inform the class that if consumers begin substituting, for example: If the prices at full service hair styling salons get too exorbitant, consumers may substitute by going to cheaper hair cutting salons. This will make the ___________ calculation lower.

A. higher; C-CPI
B. lower; C-CPI
C. lower, PPI
D. higher, PPI

Answer 1

A. higher; C-CP

Step-by-step explanation:

As the exercise says, John wants students to see that food and energy prices have risen more rapidly than other market items used in the Consumer Price Index (CPI) calculation. He wants students to see the increase in the core inflation, because food and energy are the main expenses of people. But for CPI calculation there are other items to consider. So the core inflation will be higher than the CPI (inflation, considering all items), as food and energy prices increased more than the other products considered in the CPI.

The second part of the excersise says that there might be substitution, that is people consuming less expensive goods or services, which will lead to a change in the measuring of the C-CPI as the prices to consider will be lower, so C-CPI will be less
