“…In the remote distance district (>10 km), gender and income both affect WTP decision, such that the government should continue advocating wetland conservation to help the female and low-income people living in relatively remote distance districts internalize appropriate messages and make correct choices. Interestingly, with regard to the WTP amounts of the residents, income is the most important factor, which is in line with the results of Voltaire et al (2013). This finding can be attributed to the fact that when people are asked whether they are willing to pay for wetland restoration, the primary determinant is the knowledge level of the respondents about this subject.…”

Many wetland restoration projects (WRPs) have been conducted to restore the wetland ecosystem since a massive bloom of cyanobacteria in Taihu Lake in the summer of 2007. The willingness to pay (WTP) of residents for wetland restoration was expected to exhibit spatial disparities that were used for decision making. In this study, correlation analysis, binary logistic regression, and linear regression were used to assess 400 questionnaires collected through a contingent valuation survey. Results indicated that WTP amounts and the probability of positive WTP decrease as the distance from the wetlands increases. Knowledge of WRPs was the only factor that influences whether the respondents pay in the close distance (<3 km) and medium distance districts (>3 and <10 km), whereas in the remote distance district (>10 km), gender and income also affected WTP decision aside from the knowledge of WRPs. In terms of WTP amounts, income was the determining factor in the three districts, whereas age was a factor in the medium distance area. Results also showed that the growth rate of the water price should vary according to the distance of the area from the location of the WRPs. The water price was recommended to be increased by US$ 0.522/ton, 0.520/ton, and 0.509/ton in the close, medium, and remote distance districts, respectively.

“…A higher the income level indicated a higher is the probability of being certain about WTP, which was consistent with previous studies (Petrolia and Kim, 2011;Voltaire et al, 2013). The impact of resource development had a strong positive impact on respondent uncertainty at 0.05 and 0.01 significance levels in the hypothetical and real settings, respectively.…”

a b s t r a c tThis paper focuses on examining the validity and reliability of the contingent valuation method (CVM) in the case of evaluation of ecotourism resources in Dalai Lake Protected Area (DLPA). The CVM is a primary method to evaluate resource value, however, it is subject to criticism because of its bias. Many factors result in CVM evaluation bias, which decreases validity of the method. An important factor is that the CVM assumes that all of the respondents are certain about their answers. In fact, many respondents are not very certain about their answer, therefore, identifying the respondents' certainty level and exploring a proper method to address it are critical issues. There are three objectives in the present study: first, to identify the uncertainty treatment that can more significantly reduce the hypothetical bias, resulting in a greater closeness to the Willingness to Pay (WTP) in a real setting; second, to identify the determinants of the respondents' uncertainty; and third, to test the reliability of the respondents' payment in a real setting and a hypothetical setting by comparison with our study in 2010. One thousand three hundred fifty questionnaires about the DLPA were distributed in face-to-face interviews targeted at Hulunbeier inhabitants, and 1142 questionnaires were collected. The primary main conclusions are summarized as follows. First, the treatment of a real setting reduced the hypothetical bias, increased the WTP accuracy and had better reliability compared with the hypothetical setting. Second, income, impact (the impact of resource development on DLPA) and environmental attitudes had a significant positive influence on the respondents' certainty in hypothetical and real settings, and income and impact of resource development on DLPA had more significant influences in the real setting than in the hypothetical setting. Third, the computation of the mean WTP showed that the exposure model and the asymmetric uncertainty model YES6 fell within the 95% interval around the point estimated from the real model. The WTP of the SUM (symmetric uncertainty model) was much higher than that of the real model and the hypothetical model.

“…Respondents' effort is found to be positively and significantly related to WTP US Hammitt and Zhou (2006) CVM is used to elicit people's WTP for air pollution health risk reduction. It is also used as an effective method to compare the effect of public and private vehicle mechanism on respondents' WTP China Voltaire et al (2013) This study deals with preference uncertainty in contingent WTP for a nature protection programme. They found that if a respondent is certain about his/her WTP then he/she will pick a single value for WTP otherwise he/she will go for interval values Gulf of Morbihan…”
