Biography
Professor Ziebarth is an economist whose research focuses on insurance markets and health risks. Dr. Ziebarth studies the interaction of (social) insurance systems with labor markets and population health. In particular, he is an international expert on the economics of sick leave. Another focus of his work is the driving forces and implications of risky health behavior such as smoking, drinking, or overeating. 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, he 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.
