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. Our research continues through related projects listed below. Additional and more recent papers can also be found in our personal academic pages.
