This introductory but innovative textbook on the economics of cities is aimed at students of urban and regional policy as well as of undergraduate economics. It deals with standard topics, including automobiles, mass transit, pollution, housing, and education but it also discusses non-standard topics such as segregation, water supply, sewers, garbage, fire prevention, housing codes, homelessness, crime, illicit drugs, and economic development. Its methods of analysis are primarily verbal, geometric, and arithmetic. The author achieves coherence by showing how the analysis of various topics reinforces one another. Thus, buses can tell us something about schools and optimal tolls about land pr...
The substantial and growing interest in the monetary valuation of preferences for environmental improvement, and against environmental damage, has prompted a demand for case studies illustrating methodologies and applications of valuation techniques. In this book, the first of two volumes, the authors provide detailed case studies of valuation techniques that have been used in developing countries. They demonstrate that valuation works and that it can yield significant insights into policy-relevant issues regarding conservation and economic development. The authors address a whole range of environmental issues under the broad themes of water and air quality, biological diversity and forest f...
Leonardo da Vinci, the eminent Renaissance scholar and philosopher said, "water is the driver of nature". Many may have considered it to be an overstatement in the past, but at the beginning of the third millennium, no sane individual would disagree with Leonardo's view.

The current trends indicate that the overall situation is likely to deteriorate further, at least for the next two decades, unless the water profession eschews its existing "business as usual" practices, which can only allow incremental changes to occur. Somewhat surprisingly, the water profession as a whole neither realised nor appreciated t...
To preserve the environment with the lowest possible cost to the social sector means that private costs should be aligned with social costs. Many governments in the Latin American and Caribbean Region are doing this now using market-based instruments (MBIs). This publication investigates the use of MBIs in the Latin America and the Caribbean (LAC) context. The investigation covers a sample of eleven countries in the region and a cross-section of environmental issues in an urban setting.
