Martin Carnoy (firstname.lastname@example.org) is the Vida Jacks Professor of Education at Stanford University School of Education. Dr. Carnoy is a labor economist with a special interest in the relation between the economy and the educational system. To this end, he studies the US labor market, including the role in that relation of race, ethnicity, and gender, the US educational system, and systems in many other countries. He uses comparative analysis to understand how education influences productivity and economic growth, and, in turn, how and why educational systems change over time, and why some countries educational systems are marked by better student performance than others'. He has studied extensively the impact of vouchers and charter schools on educational quality, and has recently focused on differences in teacher preparation and teacher salaries across countries as well as larger issues of the impact of economic inequality on educational quality. Dr. Carnoy received his BA in Electrical Engineering from California Institute of Technology, MA and PhD in Economics from the University of Chicago.
