# Raj Chetty The Indian-American economist who has **pioneered the use of large-scale administrative-data analysis to study economic opportunity and mobility in the United States**. Chetty (b. 1979) is currently William A. Ackman Professor of Economics at Harvard and Director of Opportunity Insights, the research center he founded. His work has been hugely influential on contemporary economic-policy debates about inequality, intergenerational mobility, and the structural barriers to economic opportunity. ## Career and contribution **Background.** Harvard (BA 2000), Harvard (PhD 2003) at age 23. Initially at UC Berkeley (2009–2014), then Stanford (2014–2018), then Harvard (2018–present). **Methodological approach.** Chetty's distinctive contribution is the systematic use of de-identified IRS tax data and other administrative records to study economic-opportunity questions at scales previously impossible. Where earlier research used relatively small survey samples, Chetty's team works with full-population administrative datasets (tens of millions of records). The methodology produces statistical precision and the ability to study small populations that survey-based research couldn't address. **Major findings.** Chetty's work has produced multiple influential findings: *Intergenerational mobility.* The "Equality of Opportunity Project" mapped intergenerational mobility across U.S. neighborhoods, identifying that mobility varies dramatically by location and revealing the specific neighborhood characteristics that predict mobility (school quality, family stability, racial segregation, income inequality). *The Lost Einsteins finding.* The 2017-2019 work with Alex Bell, Xavier Jaravel, Neviana Petkova, and John Van Reenen documented that talent for innovation appears approximately uniformly distributed across the population, but exposure to inventing during childhood is sharply unequal — producing dramatic gaps in eventual patenting rates between children with otherwise similar abilities but different backgrounds. See Lost Einsteins for the full treatment. *COVID-economic-impact tracking.* During the COVID pandemic, Opportunity Insights produced real-time tracking of economic activity that became a major resource for policy-makers. The work demonstrated how administrative-data methodology could support real-time policy analysis. ## KB significance **Empirical refutation of strict-meritocracy claims.** Chetty's body of work substantially complicates the right-wing political claim that the U.S. is broadly meritocratic. The data show that mobility opportunities vary dramatically by where you grow up; that talent for innovation is wasted by unequal exposure; that intergenerational economic position is much more predictive than meritocratic frameworks suggest. The findings are empirical, methodologically rigorous, and politically inconvenient for right-wing economic narratives. The research is widely respected across the political spectrum; the policy implications are contested. ## See also - Lost Einsteins — Chetty's most-cited framework - [[Veil of Ignorance]] — Rawlsian framework whose practical implications Chetty's work informs
