The Billion Prices Project is an academic initiative that uses prices collected from hundreds of online retailers around the world on a daily basis to conduct economic research.
This page shows our most recent research leveraging high-frequency price data, as well as the US daily inflation index (updated monthly on this page).
Our research uses high-frequency item-level data to study pricing topics in Macroeconomics and International Economics. Here are some of the papers we have recently written with online data:
