Inflation was a hot topic at today's press conference. Usually the U.S. Bureau of Labor Statistics Consumer Price Index (CPI) is used to measure price inflation. However, for several years some have found MIT's Billion Prices Project useful in estimating price inflation. The Billion Prices Project collects prices from hundreds of online retailers around the world on a daily basis to conduct economic research. One of the outputs currently produced is an Index of US inflation which is the basis for the chart below.
Project managers readily admit they don't cover all goods and services due to the nature of online sales. Still, can you imagine how little is spent on this effort compared with the cost of producing the government's CPI?
Recently the US Index was unavailable for about a week, then reappeared. The Wall Street Examiner speculates that MIT's explanation of too much work to do is not the entire story. I hope the project's US Index continues to be produced. It's a neat use of technology offering an alternative to the often criticized CPI.
