Google to map inflation using web data (Robin Harding, October 11 2010, Financial Times)

Google is using its vast database of web shopping data to construct the ‘Google Price Index’ – a daily measure of inflation that could one day provide an alternative to official statistics.

The work by Google’s chief economist, Hal Varian, highlights how economic data can be gathered far more rapidly using online sources. The official Consumer Price Index data are collected by hand from shops, and only published monthly with a time lag of several weeks.

At the National Association of Business Economists conference in Denver, Colorado, Mr Varian said that the GPI was a work in progress and Google had not yet decided whether to publish it.

While the Federal Reserve is unlikely to panic just yet, Mr Varian said that the GPI shows a “very clear deflationary trend” for web-traded goods in the US since Christmas. Although the data are not seasonally adjusted, Mr Varian said that prices rose during the same period a year ago. The ‘core’ CPI in the US, which excludes food and energy, rose 0.9 per cent on a year ago in August.
