This paper begins with a summary of the Bank's involvement with large infrastructure projects, including dams, since the 1960s. In the energy sector, the IDB has provided financing for the construction of a large number of hydroelectric projects. A large proportion of IDB's financing for...

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...

In this note, the authors detail the mechanics of the nonparametric mean and variance calculations of finding willingness to pay (WTP) estimates. There are (at least) three nonparametric estimators of mean WTP that can be obtained from referendum CV survey data. The logic behind all three...
