These prescriptions balanced consumer and producer interests and accounted for a number of important elements of public enterprise, such as breakeven requirements, service quality and cost tradeoffs, and peak loads. Interest in the topic goes back many years, including the early work of Coase (1946), Lewis (1941) and Ramsey (1927). However, the well developed prescriptions of the theory stand out in contrast to the practice in public enterprise monopoly and even more so with regulated monopoly. In this chapter we review the theory and examine the divergence between it and practice. Despite the elegance and simplicity of the theory, with its obvious appeal to economists, its adoption in practice has been disappointing. While we show the stark contrast between theory and practice, we also point to some unifying principles by which to approach pricing of regulated or public enterprise monopolies. These principles are in the spirit of our now more modest expectations about realistic objectives for regulation. Our ability to derive unifying principles derives from advances that have been made in the last 20 years or so in the understanding of information in economics, the role of rents and rent seeking and information rents. First, we review the theory, including some of its origins and antecedents, but in the interests of readability and accessibility derivations and proofs are confined to the Technical...
