The movement to implement market-based approaches to allocating water is gaining ground across California and in other western states. Proponents argue that markets offer an efficient and cost-effective means of promoting conservation -- those who need water would pay for it on the open market, while others would conserve rather than pay increased prices.Rivers of Goldtakes a new look at California's water-reallocation challenge. The author explains the concept of water markets and the economic theory undergirding them. He shows how some water markets have worked -- and others have failed -- and gives the reader the analytic tools necessary to understand why. The book: provides an overview of water-supply issues in California compares the situation in California with that of other western states considers the different property rights regimes governing current use and their fit with water market institutions explains how water markets would work and their benefits and drawbacks as an allocation mechanism presents a series of case studies of water markets currently in effect in California offers a list of principles for water market designRivers of Goldoffers a balanced understanding of both the role that markets can play in reallocating water and the limitations of the market mechanism. In the end, the author offers a comprehensive assessment of the institutional design features that any water market should incorporate if it is to reallocate water effectively, in California or in any other region where water is scarce.Rivers of Goldis the first book to provide a detailed examination of water markets and the institutional design issues associated with them. It is the only book available that presents in-depth case studies of actual water-market transactions, and will be essential reading for water resource professionals and resource economists, as well as for students and scholars of environmental policy, environmental economics, and resource economics.
