Herbert Mohring


Herbert Mohring was a transportation economist who taught at the University of Minnesota from 1961–1994. He received his Ph.D. from Massachusetts Institute of Technology in 1959, with a thesis on the life insurance industry supervised by Robert Solow.
He is widely known for his identification of what was dubbed the Mohring effect of increasing returns in public transportation.
Mohring and Harwitz also showed that the revenues from the first-best congestion tax exactly cover the capacity costs of highways when highways possess constant returns to scale.
