Raihan Alam is a third year PhD student in Management and National Science Foundation Graduate Research Fellow. He studies the causes and consequences of moral disagreement, with applications to criminal justice, violence, and political polarization. In recent work, he has found that incentivizing punishment can destabilize cooperation and that stock trading by members of Congress can reduce ordinary citizens' willingness to comply with the law. Moving forward, he is investigating how moralistic anger drives political action. His interest in CARTA lies in understanding the evolution of large-scale cooperation in Homo Sapiens.
