A concise treatment of water-resource economics. Based upon political economy perspectives, it draws upon a worldwide range of case-studies. There is guidance on abbreviations, acronyms, and technical terms.
Most of the books published previously in the field of water resource eco nomics focus on particular aspects of water economics such as institutions, pricing or water markets, but none of them have given particular attention to methodological questions. However, the applied methodology within economic research has made some remarkable advances over the last 10-20 years. Some of these advances are of particular interest to the field of water economics. Therefore, we think that a book that focusing on methodological advances within the field of water resource economics and showing how these advances can be applied in economic analysis of water issues makes a nice complement to the existing literature in this field. We identified five areas where we consider the methodological advances to be of particular importance: 1) asymmetric information and game theory, 2) un certainty, 3) space, 4) water quality and 5) production and technology adoption. The selected papers for the book fall entirely within these categories. The book ''Frontiers in Water Resource Economics" draws to a great extent on papers which were presented at the 7^^ Conference of the International Water and Re source Economics Consortium, June 3-5,2001 held in Girona, Catalonia, Spain, This conference was jointly organized with the 4^^ Conference of Environmen tal and Resource Economics by the Department of Economics, University of Girona.
Bringing together 14 papers previously published in refereed journals, The Price of Water provides information that many readers would not otherwise have access to through their professional and academic libraries. The basic disciplines of the articles are economics and philosophy, built upon by discussion of hydrology, civil engineering, water law and water resource planning. The scope of the book is broad, dealing with a diverse range of subjects such as regional and catchment planning and integrated water resources management. Topics considered include: both water quantities and qualities, drought management, the ‘virtual water’ controversy, farmers’ water-rights, the economic demand for water, the design of abstraction charges, the cost and use of irrigation water, the design of effluent charges, the ‘willingness-to-pay’ methodology. The Price of Water aims to link up economics with the other dominant water resource disciplines, establishing an economics of the real world, rather than an academic abstraction - the hydrosocial balance. In providing a new and practicable basis for planning outsream water investments, as well as understanding the baseline situation, the development and use of the hydrosocial balance to modelling water resources supply and use at the regional (or river basin) scale delivers this link.
This book uses resource economics costing approaches incorporating externalities to estimate the returns for the country’s irrigation and demonstrates how underestimating the cost of water leads farmers to overestimate profits. The importance of the subject can be judged in light of the fact that India is the largest user of groundwater both for irrigation and for drinking purposes, pumping twice as much as the United States and six times as much as Europe. Despite water’s vital role in ensuring economic security for the nation and farmers alike by supporting more than 70% of food production, water resource economists are yet to impress upon farmers and policymakers the true value of water and the urgent need for its sustainable extraction, recharge and use. In an endeavor to promote more awareness, the book further delineates the roles of the demand side and supply side in the economics of irrigation, and explains how the cost of water varies with the efforts to recharge it, crop patterns, degrees of initial and premature well failure and degrees of externalities. It also discusses the importance of micro-irrigation in the economics of saving water for irrigation, estimating the marginal productivity of water and how it improves with drip irrigation, the economics of water sharing and water markets, optimal control theory in sustainable extraction of water, payment of ecosystem services for water and how India can effectively recover. In closing, the book highlights the role of socioeconomic and hydrogeological factors in the economics of irrigation, which vary considerably across hard rock areas and the resulting limitations on generalizing.
Updated edition of a comprehensive introduction to the economics of water management, with self-contained treatment of all necessary economic concepts. Economics brings powerful insights to water management, but most water professionals receive limited training in it. The second edition of this text offers a comprehensive development of water resource economics that is accessible to engineers and natural scientists as well as to economists. The goal is to build a practical platform for understanding and performing economic analysis using both theoretical and empirical tools. Familiarity with microeconomics or natural resource economics is helpful, but all the economics needed is presented and developed progressively in the text. The book focuses on the scarcity of water quantity (rather than on water quality). The author presents the economic theory of resource allocation, recognizing the peculiarities imposed by water, and then goes on to treat a range of subjects including conservation, groundwater depletion, water law, policy analysis, cost–benefit analysis, water marketing, privatization, and demand and supply estimation. Added features of this updated edition include a new chapter on water scarcity risk (with climate change and necessary risk tools introduced progressively) and new risk-attentive material elsewhere in the text; sharper treatment of block rates and pricing doctrine; expanded attention to contemporary literature and issues; and new appendixes on input–output analysis, water footprinting and virtual water, and cost allocation. Each chapter ends with a summary and exercises.
This second edition includes updated information and an exploration of water issues outside the United States, as well as a new application of behaviorial and experimental economics to the topic. A concise introduction to issues of water quality and quantity in both urban and agricultural settings, Water Resource Economics and Policy will be a valuable resource or text for students and researchers in the fields of agricultural economics, geography, law and hydrology. Those involved in water resource agencies and private utilities will also find the book a useful reference.
The purpose of this book is to develop a general economic model which integrates the quantity and quality issues of water resource management and to provide, along with a detailed criticism of the policy instruments now in use, alternative proposals concerning the efficient allocation and distribution of water. In particular we treat water as a multi-product commodity where the market plays a major role in determining water quality-discriminant pricing and its value to the user. We examine the process of moving from administrative allocation and regulation to privatization of the water industry as the key element in promoting effective competition and in providing economic incentives for greater efficiency. Water quantity and quality, considered independently of each other, have been the subject of numerous studies during the last twenty years. Let us recall briefly the most outstanding among them. A variety of models have been constructed concerning the optimal scheduling and sequence of water-supply projects: dynamic programming for solving multi-bjective functions in water resource development; planning models for coordinating regional water-resource supply and demand, etc. Other studies have devised water-quality management models, including multi-period design of regional or municipal wastewater systems; cost-allocation methods to induce effluent dischargers to participate in regional water systems; models to predict the quality of effluent (in particular, whether it meets certain established standards); models for finding optimal waste-removal policies at each of the polluting sources, and so on.
Water scarcity, whether in the quality or quantity dimension, afflicts most countries. Decisions on water management and allocation over time, space, and among uses and users involve economic considerations. This Handbook assembles research that represents recent thinking and applications in water economics. The book chapters are written by leading scholars in the field who address issues related to its use, management, and value. The topics cover analytical methods, sectoral and intersectoral water issues, and issues associated with different sources of water.
The marginal price elasticities estimated by Martinez-Espineira conforms to expectation. The price specification that accounts for the changing proportion of water users in each block yields a higher elasticity (-0. 47) compared to the spec ification ignoring this feature of the data. However, this difference is not found to be statistically significant, a result attributed to the low power of the test (small sample size limiting the accuracy of estimates). In conclusion, the paper provides a theoretically correct price specification for demand functions under block pricing and aggregate data. The empirical findings in the paper, however, are not conclusive and further empirical work using more data and alternative (nonlinear) demand functions, is needed to show the practical implications of the arguments put forward by the Martinez-Espineira's paper. Static empirical consumer demand functions estimated with aggregate data are well known to suffer form serial correlation and other statistical problems asso ciated with misspecified dynamics. These dynamics arise because consumers do not react immediately to a change in prices due to their largely predetermined lifestyle. In the case of demand for water, for example, current purchases can be largely predetermined due to commitments arising from past purchases such as swimming pools, bathtubs, dishwashing machines, etc. Muellbauer and Pashardes (1992) show that the autoregressive nature of consumer demand data can be cap tured in a theoretically consistent manner by incorporating intertemporal aspects of consumer behaviour in the model through habit formation and durability.
