John N. Friedman is an associate professor of economics and international affairs and public policy. His research brings together theory and data, harnessing the power of large administrative datasets to yield policy-relevant insights on a wide range of topics, including taxation, healthcare, and education quality. His work has appeared in top academic journals as well as in major media outlets. His most well-known papers estimate the long-term effects of teachers on student outcomes such as college attendance and earnings; in just one year, a great teacher can raise the lifetime earnings of a single class of students by nearly $1.5 million. This work was cited by President Obama in his 2012 State of the Union Address. Friedman has also worked as special assistant to the President for economic policy at the National Economic Council in the White House from 2013-2014. He holds a PhD in economics, an AM in statistics, and a BA in economics, all from Harvard University. He is a faculty research fellow at the National Bureau of Economic Research.
