The Nicholas C. Petris Center is a health economics research center that focuses on empirical research on important health policy topics. Our mission is to guide public policy by creating the data and conducting the research needed to understand today’s complex healthcare market. It provides up-to-date information on changes in the healthcare system that may impact the healthcare marketplace and alter its capacity to provide high-quality care at competitive prices. The Petris Center focuses on consumer protection, affordability, and access to health care, especially for low and middle-income individuals. Our current research is centered around concentration, regulation, and competition within healthcare markets, as well as topical issues in mental health, the health workforce, integrated care, and universal healthcare initiatives, particularly in California. It conducts studies and provides objective information to lawmakers, regulators, consumer-advocates, health care providers, and the public at large.
