Overview

Isaac M. Opper is an applied microeconomist who does work primarily on the economics of education, health economics, labor economics, and personnel economics. Much of his research relates to the measurement of teacher quality, including a paper published in the American Economic Review which shows that the positive impact that teachers have on their students spills over to affect their students’ future peers. Other work includes an impact evaluation of the New York City Community School Initiative written about in the New York Times and Wall Street Journal and a paper forthcoming at the Journal of Labor Economics which shows that there are large peer effects in a job training program and that these peer effects impact the optimal assignment of individuals to the treatment. Opper is a member of the Pardee RAND Graduate School faculty. He graduated with a Ph.D. in economics from Stanford University.
