Billion Prices Project

The Billion Prices Project was an academic initiative at MIT and Harvard that used prices collected from hundreds of online retailers around the world on a daily basis to conduct research in macro and international economics. It was founded in 2008 by Alberto Cavallo and Roberto Rigobon, and remained active until 2016.
