Some day, may be something like this will replace the inflation numbers that governments publish?
From the website:
The Billion Prices Project is an academic initiative that collects prices from hundreds of online retailers around the world on a daily basis to conduct economic research.
This webpage showcases a series of experimental inflation indexes. We upload our most recent research leveraging high-frequency price data and focus on price indexes that can enhance policy decisions. Currently, we are showing the US daily index, a price and product availability index in Japan, as well as a World Inflation Index that provides real-time information on global inflation trends.
