“…In this study, the level of negative answers (54.4%) was high when compared to other studies in Brazil; Gullo (2010), for example, obtained 34.8% of negative answers for the preservation of a dam, and in the study of Silva and Lima (2004) on the preservation of the Chico Mendes Park, in Rio Branco, 32% of the responses were "zero". Similar results were reported by Saz-Salazar and Guaita-Pradas (2013), which had 52% of "zero" answers and by the study of Dziegielewska and Mendelshon (2007), in which more than 65% of the answers were "zero".…”

This paper estimates the value of environmental damage generated by pollution in the artificial lake Salto Caveiras, evaluating the willingness to pay (WTP) of the local population for its recuperation and conservation. Environmental Concern Scale (ECS) was introduced, in addition to the socioeconomic variables, collected by the Contingent Valuation Method (CVM) and modeled by Logit regression and evaluated by multivariate statistics instruments, utilizing Principal Components Analysis (PCA). We demonstrate that 45.6% of the interviewed are willing to pay monthly. The others answered negatively: 18.9% because of payment incapacity, 12.8% would donate a smaller value than the one proposed and 22.8% gave a protest response.. The introduction of ECS as a new variable to CVM is significant as a unique and innovative variable provided by multivariate analysis indicated to be promising, what recommends such procedures to other studies.Keywords: environmental concern; multivariate analysis; valuation economic; water resource; water pollution. RESUMOO objetivo deste trabalho foi estimar o valor dos danos ambientais gerados pela poluição ao lago artificial Salto Caveiras, a partir da mensuração da disposição a pagar (DAP) da população local pela recuperação e conservação do mesmo. Foi introduzida na análise uma Escala de Consciência Ambiental (ECA), além do perfil socioeconômico, obtidos com a aplicação do Método de Valoração Contingente (MVC) e modelados pela regressão Logit e avaliados por instrumentos da estatística multivariada, utilizando-se da Análise de Componentes Principais (ACP). Os resultados revelam que 45,6% dos entrevistados estão dispostos a contribuir. Os outros responderam negativamente: 18,9% devido à incapacidade de pagamento, 12,8% propuseram um valor menor do que o sugerido e 22,8% deram uma resposta com caráter de voto de protesto. A introdução da ECA como uma nova variável ao MVC se mostrou significativa, bem como a visão holística, inédita e inovadora proporcionada pela análise multivariada se mostrou promissora, recomendando-se tais procedimentos para outros estudos.Palavras-chave: percepção ambiental; análise multivariada; valoração econômica; recurso hídrico; poluição da água.

“…Protest bidders are respondents who may actually place some value on the commodity in question but refuse to pay on the basis on ethical or other reasons. Protest voters should be excluded during analysis of CVM data because they can bias estimations of central tendency measures of WTP [60]. Protesters were identified as respondents who declared zero on all valuation questions, and held at least one effective protest belief.…”

“…Following common practice in the CV literature (e.g. Strazzera et al, 2003;Dziegielewska and Mendelsohn, 2007), these protest responses were omitted from further analysis, while the true zero votes were kept in 1 . This yields a total of 1,315 useable responses.…”

The effect of preference uncertainty on estimated willingness to pay (WTP) is examined using identical payment cards and alternative uncertainty elicitation procedures in three split samples, focusing on air quality improvement in Nairobi. The effect of the stochastic payment card (SPC) and polychotomous payment card (PPC) are compared with a conventional payment card (PC). Substantial financial support is found for improved air quality in Nairobi, with approximately 85 percent of the whole sample stating a positive WTP. The way WTP values are elicited, with and without ability to express preference uncertainty, has significant effect on WTP welfare estimate. Allowing respondents to express experienced uncertainty when stating WTP value yields more conservative, but less accurate WTP values for inclusion in policy analysis. The PPC seems to hold most promise since it is easier to understand and imposes less cognitive burden on survey participants than the SPC in a developing country context.
