Nathan W. Tefft

Associate Professor of Economics



Pettengill Hall, Room 274


Tefft’s research reflects his interests in risky health behaviors and health policy. He has worked on projects studying outcomes including obesity, smoking, vaping, mental health, alcohol consumption, fatal automobile crashes, and dietary supplements, typically in the context of labor markets, macroeconomic fluctuations, or government policies that impact these behaviors.

He has also been involved in interdisciplinary projects that more broadly intersect with public health and public policy.  Some examples include the relationship between health and early childhood intervention programs, soft drink tax policies, SNAP participation, dietary supplements, and drunk driving.

Tefft also serves as an Associate Editor for Health Economics.

He teaches courses in health economics, microeconomics, econometrics, and statistics.

Outside of his academic work, he serves as a board member of Onpoint Health Data, board member and Treasurer of the Friends of Baxter State Park, and is always looking forward to the next opportunity to camp and hike with his family. He also enjoys CrossFit, running, skiing, and playing with his kids in whatever activity currently excites them.
