Fixed Charges in Rates: 1938 Classic on Rate Design
Havlik’s timeless analysis: Justification for fixed charges in rates, their just level relative to variable charges.
I found this book at the Library of Congress and had to have it. Fortunately AbeBooks, that has just about anything old and obscure, did have for sale this 1938 classic on rate design. And that's how I came to own a copy of "Service Charges in Gas and Electric Rates" by Dr. Hubert Havlik.
