Thus, if the price index leaves out new goods, it overlooks one of the ways in which the cost of living is improving. - In addition, the price of a new good is often higher when it is first introduced and then declines over time. If the new good is not included in the CPI for some years, until its price is already lower, the CPI may miss counting this price decline altogether. ### CPI and core inflation index ![CPI and core inflation index](https://image-v2.cdn.app.senecalearning.com/2020-01/f53ba8e0-f3f2-4a91-be57-fc15bd929f3b/bread-1284438_1920-min.jpg) - Economists typically calculate a core inflation index by taking the CPI and excluding volatile economic variables. In this way, economists have a better sense of the underlying trends in prices that affect the cost of living. - Examples of excluded variables include energy and food prices, which can jump around from month to month because of the weather. ## Test yourself on The Consumer Price Index [Practise this topic for free](https://app.senecalearning.com/classroom/course/7b55fd22-05a1-435c-9704-355732f0e415/section/66b38989-cbb9-422c-94db-33a821cf5a6c/session) -
