Water resource management is complicated in practice on account of the diverse nature of the resource and its many uses. This volume reports economic research on the theory, practice, and policy of water management. It is distinguished by the number and the range of the applications it considers. Chapters consider problems in the estimation of water demand in residential and agricultural contexts. Efficiency and externality considerations are considered in chapters concerning common aquifers as well as domestic conservation. Management policies are discussed in regard to chemical contamination, reservoir construction, and industrial regulation.
