An Introduction To Financial And Economic Modeling For Ultity Regulators

The most effective regulators in developing countries are following remarkably similar approaches. The main common element across "best practice" countries is the use of relatively simple quantitative models of operators' behavior and constraints to measure the impact of regulatory decisions on some key financial and economic indicators of concern to the operators, the users, and the government. The authors provide an introduction to the design and use of these models. They draw on lessons from international experience in industrial and developing countries in ordinary or extraordinary revisions and in the context of contract renegotiations. Simplifying somewhat, these models force regulators to recognize that, in the long run, private operators need to at least cover their opportunity cost of capital, including the various types of risks specific to the country, the sector, or the projects with which they are involved. Because these variables change over time, scheduled revisions are needed to allow for adjustments in the key determinants of the rate of return of the operator. These revisions are a recognition of the fact that all these determinants-tariffs, subsidies, quality, investments, and other service obligations-are interrelated and jointly determine the rate of return. At every revision, the rules of the game for the regulator are exactly the same: to figure out the changes in the cost of capital and to adjust the variables driving the rate of return to ensure that it continues to be consistent with the cost of capital. If they can draw on reasonable data, these models do everything any financial model would do for the day-to-day management of a company but take a longer term view and include an explicit identification of the key regulatory instruments. They can monitor the consistency between cash flow generated by the business on the one hand and debt service and operational expense needs on the other to address the main concerns of the operators. They can also account for a large number of key policy factors including access and affordability concerns for various types of consumers. They generally account for the sensitivity of operators and users to various regulatory design options.

This monograph is concerned with the determination of the allowed rate ofreturn in rate cases which, in part, determines the rates ofcharge to customers of public utilities. Rate of return determination has been a central topic in utility regulation for a century. Recent changes in the traditionally regulated markets - electricity, gas, and telephone - have shoved discussion of rate of return determination into the background, replacing it by technology changes, competition, downsizing, deregulation, and reg'ulatory incentive systems. These new issues have made the regula tory sector, which had the reputation of being stodgy and uninteresting, an exciting field ofstudy. But rate ofreturn is not dead. It will playa key role in whatever the new structure ofthe regulated sector. Separating generation from transmis sion and distribution will not eliminate the need for rate of return analysis in the electric utility industry. Rather, it may well increase the number of companies for which the rate of return needs to be determined. It will playa fundamental role in the new regulatory environment. Incentive systems in the regulated sector may be the wave of the future but they will use the required rate ofreturn as a benchmark. Rate case will persist. Most rate cases include opposing testimony as to the "fair" rate of return or even the cost ofcapital for a public utility whose rates are at issue.

This title provides a practical guide for regulators, policy-makers, and utility managers for establishing regulatory accounts that can be the cornerstone for better, more complete, and more reliable information. It sets out the essential accounting features of regulatory accounts and provides practical guidance on controversial areas such as cost allocation, asset valuation, and depreciation. It emphasizes the essential requirements for consistency with Generally Accepted Accounting Principles (GAAP).

"Estache reviews the recent economic research on emerging issues for infrastructure policies affecting poor people in developing countries. His main purpose is to identify some of the challenges the international community, and donors in particular, are likely to have to address over the next few years. He addresses six main issues: (1) the necessity of infrastructure in achieving the Millennium Development Goals; (2) the various dimensions of financing challenges for infrastructure; (3) the debate on the relative importance of urban and rural infrastructure needs; (4) the debate on the effectiveness of infrastructure decentralization; (5) what works and what does not when trying to target the needs of the poor, with an emphasis on affordability and regulation challenges; and (6) the importance of governance and corruption in the sector. The author concludes by showing how the challenges identified define a relatively well integrated agenda for both researchers and the international infrastructure community. This paper,a product of the Office of the Vice President, Infrastructure Network,is part of a larger effort in the network to stimulate more analytical assessments of emerging issues in the sector"--World Bank web site.

During the 1990s, infrastructure concessions were hailed as the solution to Latin America's endemic infrastructure deficit, by combining private sector efficiency with rent dissipation brought about by competition. This publication examines the design and implementation of over 1,000 examples of concession contracts, in order to identify the problems that have occurred in the process. It goes on to highlight lessons to be learned for the future, in order to realise the potential benefits of infrastructure reform and to contribute to economic growth and poverty reduction.
