Dr. Meiselbach's research investigates how policy and market forces shape insurer and employer decisions in health insurance markets and how these decisions affect enrollee access, affordability, and health outcomes. His work spans labor economics, insurance design, market power, and behavioral health. He frequently publishes in leading journals such as Health Affairs, Journal of Health Economics, and Medical Care Research and Review.
