Professor Ziebarth is an economist whose research focuses on health, public and labor economics. Dr. Ziebarth studies the interaction of (social) insurance systems with labor markets and population health. Another focus of Dr. Ziebarth's work is the driving forces and implications of risky health behavior such as smoking, drinking, or overeating.
In particular, Nicolas Ziebarth is an international expert on the economics of sick leave. Over the past years, his sick leave research has been featured by the New York Times, the Washington Post, the Wall Street Journal, the WHO or the Economist, and cited as a reason for the Healthy Families Act, the initial FFCRA emergency sick leave provision as well as its extension.
Dr. Ziebarth has won several awards for his research. According to RePEc, he ranks among the top 0.5% of young economists with less than 15 years of research activity.
At Cornell, Professor Ziebarth teaches a comparative health care system course for undergraduate students (PAM 3870), a Sloan MHA introductory course to the U.S. health care system (PAM 5570), and the second sequence of health economics for PhD students (PAM 6420).
Professor Ziebarth is Associate Director of the Cornell Institute for Healthy Futures.
