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...

This document presents the proceedings of a workshop on financial incentives for industrial forest plantations, held at the Inter-American Development Bank (IDB) on January 19, 1995. The main objectives of the workshop were, first, to exchange ideas among workshop speakers and participants...

This paper (ENV-126) was originally presented at a National Science Foundation Workshop on Alternatives to Traditional Contingent Valuation Methods in Environmental Valuation, held at Vanderbilt University, Nashville Tennessee, on October 15-16, 1998. This paper reviews the past ten years of the...

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...

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...

This working paper develops upon the idea that economic analysis has a definite role to play in informing decision makers about the desirability of going ahead with an investment project designed to improve environmental quality and also that the role of precision in this matter is not trivial....

This working paper addresses the issues: 1) whether there is a simultaneous equations problem when estimating demand for water with multipart rate schedules and, if there is one, what techniques should be used to correct for it; and 2) whether average or marginal price is the relevant measure in...
