The Economic Policy Institute (EPI) is a 501(c)(3) non-profit American think tank based in Washington, D.C., that carries out economic research and analyzes the economic impact of policies and proposals. Affiliated with the labor movement, the EPI is usually described as presenting a left-leaning and pro-union viewpoint on public policy issues. Since 2021, EPI has been led by economist Heidi Shierholz, the former chief economist of the Department of Labor.
