Herbert Mohring is a transportation economist
who taught at the University of Minnesota
for many years. He received his Ph.D.
from Massachusetts Institute of Technology
in 1959.
He is widely known for his identification of what was dubbed the Mohring effect
of increasing returns in public transportation.
Mohring and Harwitz (1962) also showed that the revenues from the first-best congestion tax
exactly cover the construction costs of highways when highways possess constant returns to scale.
