Rajiv Sethi is a Professor of Economics at Barnard College, Columbia University and an External Professor at Santa Fe Institute. He has previously held visiting positions at Microsoft Research and at the Institute for Advanced Study in Princeton. He is on the editorial boards of the American Economic Review and Economics and Philosophy

His current research deals with information and beliefs. In collaboration with Brendan O’Flaherty, he has examined the manner in which stereotypes affect interactions among strangers, especially in relation to crime and the criminal justice system. Their book, Shadows of Doubt: Stereotypes, Crime, and the Pursuit of Justice was published by Harvard University Press in 2019. 

Rajiv is also currently working on the forecasting of geopolitical events using methods that combine machine models with human judgment. This involves the development of prediction markets in which trading bots representing machine models interact with human traders to generate hybrid forecasts.
