Here are three books I recommend to colleagues interested in gaining a deeper understanding of regulatory principles
Widely considered the bible for regulatory, it provides deep well researched content. Highly recommended for those looking to attain expert level as the book is quite pricey (nearly $200 last time I checked) and with that many pages, its not for the faint of heart.
This is a quick an easy read that I have often recommended to my accounting staff. It’s a great introduction to revenue requirement, rate base, cost of capital and tariff policies. And at around $6 on kindle, the price is right.
Written by a lawyer but try not to hold that against him J because the text is jam packed with cases and will give you an enhanced lens from which to think through your regulatory business.
