Founded in 2010, the Human Capital and Economic Opportunity Global Working Group (HCEO) is a collaboration of over 400 researchers, educators, and policy makers focused on human capital development and its impact on opportunity inequality. HCEO’s unique approach enables collaboration among scholars with varying disciplines, approaches, perspectives, and fields. This means the integration of biological, sociological, and psychological perspectives into traditionally economic questions. The result is innovative thinking and approaches to inequality and human capital development research.
