This book arose out of a paper that I wrote for the World Bank at the request of Ariel Dinar, the editor for the series in which this volume appears. I began that paper by pointing to the growing importance of demand-side considerations in water resources: "The provision of potable water is one of government's oldest functions with evidence of this activity stretching back thousands of years. During much of that time, water demands were taken as exogenously given and the principle task of authorities was defined as an engineering one: how to supply a given quantity of water at least cost. In recent years, however, concerns have arisen from observations of excessive water use, degraded water quality and continued inadequate service for many, especially the very poor. As a result of these and other concerns, there is a growing effort to view water resource allocation from a perspective that incorporates consumers' preferences along with supply constraints into management plans. " (Renzetti, 2000, p. 123). The purpose of this volume is to examine, in greater detail than was possible in that article, what is known regarding the economic characteristics of the demand for water. Thus, this book is meant to be an extended critical review of the state of the art.

Water provides benefits as a commodity for agriculture, industry, and households, and as a public good such as fisheries habitat, water quality and recreational use. To aid in cost-benefit analysis under conditions where market determined price signals are usually unavailable, economists have developed a range of alternative valuation methods for measuring economic benefits. This volume provides the most comprehensive exposition to-date of the application of economic valuation methods to proposed water resources investments and policies. It provides a conceptual framework for valuation of both commodity and public good uses of water, addressing non-market valuation techniques appropriate to measuring public benefits - including water quality improvement, recreation, and fish habitat enhancement. The book describes the various measurement methods, illustrates how they are applied in practice, and discusses their strengths, limitations, and appropriate roles. In this second edition, all chapters have been thoroughly updated, and in particular the coverage of water markets and valuation of ecosystem services from water has been expanded. Robert Young, author of the 2005 edition, has been joined for this new edition by John Loomis, who brings additional expertise on ecosystem services and the environmental economics of water for recreational and other public good uses of water.

Water institutions establish the incentives, information, and compulsions that guide behaviour and influence economic outcomes. Water pricing policies that reflect the marginal cost of supply can bring about several positive benefits in the pipe-borne water sector including: 1) greater water use efficiency; 2) an increase in revenues that can be utilised to improve services; and 3) additional funds to enhance and expand the operation and maintenance of pipe-borne water supply systems. In order to design an appropriate pricing policy and bring about these positive changes, managers of pipe-borne water supply systems require an understanding of the determinants of water demand, supply and welfare changes. Further, the use of economic methodologies to estimate the effects of factors that influence pipe-borne water demand, supply and welfare in developing nations can assist water utility operators and policy makers to predict consumption responses to changes in water pricing. In turn, this provides important evidence for these decision makers to determine if price changes will result in higher revenues that can be used to fund critical infrastructure extension and maintenance. This is particularly important for developing nations where revenue constraints on water authorities can limit access to pipe-borne water supplies for large sections of the population. This book identifies under-pricing as the major problem faced by the Sri Lankan pipe-borne water sector. Recently, the water authority in Sri Lanka restructured its pricing strategy for pipe-borne water with the objectives of reducing water consumption and expanding the network. However, the success of the current pricing structure in achieving these objectives is uncertain. Therefore, to overcome the problems, this study examines the use of cost-reflective alternative pricing strategies for pipe-borne water distribution services. The book evaluates current and alternative pricing strategies for water against the criteria of efficiency and equity while maintaining the financial viability of the national water utility. In order to analyse the welfare impacts, understanding the demand for pipe-borne water by different user groups and the cost of pipe-borne water provision must be considered.

This book focuses on the structural analysis of demand under block rate pricing, a type of nonlinear pricing used mainly in public utility services. In this price system, consumers are presented with several unit prices, which makes a naive analysis biased. However, the response to the price schedule is often of interest in economics and plays an important role in policymaking. To address this issue, the book adopts a structural approach, referred to as the discrete/continuous choice approach in the literature, to develop corresponding statistical models for analysis. The resulting models are extensions of the Tobit model, a well-known statistical model in econometrics, and their hierarchical structure fits well in Bayesian methodology. Thus, the book takes the Bayesian approach and develops the Markov chain Monte Carlo method to conduct statistical inferences. The methodology derived is then applied to real-world datasets, microdata collected in Tokyo and the neighboring Chiba Prefecture, as a useful empirical analysis for prediction as well as policymaking.

This book was stimulated by and sets out to analyse a political battle over water pricing by a municipal system. Originally published in 1984, this title provides improved methods for demand function estimation where block rates are involved, suggests procedures for rational pricing of municipal water, and explains how politics can dominate when real decisions are made. Due to the additional virtue of this title being easy to read, it is ideal for students interested in environmental studies, economics, and policy making, as well as for those involved with municipal services and resource management in general.
