Investing in Water Quality: Measuring Benefits, Costs and Risks, explores the methods and analytical tools available for making better investment decisions when our knowledge of the costs and benefits of water quality improvement is imprecise and the future is uncertain. The study demonstrates...

This technical paper argues that Monte Carlo risk analysis offers a more comprehensive and informative way to look at project risk ex-ante than the traditional (and often arbitrary), one-influence-at-atime sensitivity analysis approach customarily used in IDB analyses of economic feasibility....

This study uses contingent valuation (CV) methods to estimate the benefit of an environmental water quality project of the Tietê River and its tributaries that flow through the São Paulo, Brazil, Metropolitan Area (SPMA). This paper demonstrates the range alternative central tendency measures...

One of the first questions that has to be answered in the survey design process is "How many subjects should be interviewed?" The answer can have significant implications for the cost of project preparation, since in Latin America and the Caribbean costs per interview can range from US$20 to...

Fundamentally, this paper is about the value of information. Whenever a cost-benefit analysis has to be undertaken using benefits that are estimated from household survey data the size of the survey sample must be specified. The most obvious case in the valuation of environmental amenity...

The Bank is receiving an increasing number of requests from state and municipal governments to finance publicly owned convention centers. This paper suggests that few of these projects will bring the benefits expected and may impose fiscal burdens on states and municipalities that will make it...
