PHILADELPHIA -- Speaking at a two-day Behavioral Economics and Health Symposium organized by the Penn CMU Roybal P30 Center, former White House healthcare advisor Ezekiel Emanuel frankly discussed how "push back" altered what became the current regulations for Accountable Care Organizations (ACOs). Now a Penn Vice Provost and chair of the Perelman School of Medicine's Department of Medical Ethics & Health Policy, the Harvard-trained Ezekiel was one of the architects of the Patient Protection and Affordable Care Act. The Penn-CMU Royal Center in Behavioral Economics and Health is a research partnership between the University of Pennsylvania's Leonard Davis Institute of Health Economics and Carnegie Mellon University's Center for Behavioral Decision Research.
