Zack Cooper is an Assistant Professor of Health Policy and of Economics at Yale University. He is also a Resident Fellow at the school’s Institution for Social and Policy Studies (ISPS), where he directs the ISPS Health Center. Professor Cooper’s work is focused on using big data analysis and economic research to improve health care policy. There are three strands to his work. The first is examining the growth and variation in health care spending in the United States. The second is analyzing how competition in hospital and insurance markets impacts health care providers’ quality, prices, and productivity. The third is examining how information and incentives influence how individuals choose doctors and hospitals and spend on health care services. Professor Cooper received his undergraduate degree from the University of Chicago and his PhD from the London School of Economics where he remains a Faculty Associate at the school’s Centre for Economic Performance.
