Moshe Hoffman is a Research Scientist at the Max Planck Institute for Evolutionary Biology and Lecturer at Harvard's Department of Economics.
Moshe obtained his Ph.D. in Economics from the University of Chicago, Booth School of Business and his B.S. in Economics from the University of Chicago.
Moshe applies game theory, models of learning and evolution, and experimental methods, to try to decipher the (often non-conscious) motives that shape our social behavior, preferences, and ideologies.
Together with Erez Yoeli, he co-designed and teaches "Game Theory and Social Behavior" which lays out this approach. The approach is also presented in their recent book "Hidden Games", published with Basic Books, and in this research statement.
