Professor Ziebarth is an international expert on the economics of sick leave. He has published numerous peer-reviewed articles on paid sick leave in the United States and Europe. More generally, Dr. Ziebarth studies the interaction of social security systems with labor markets and population health. 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. At Cornell, he teaches a comparative health care system course for undergraduate students (PAM 3870), an 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).
