“…The researcher restricted total sample size in to 270, and it was distributed for two kebeles proportionally. Identifying the attributes and attribute levels is the first step to undertake choice experiment survey design (Mesfin, 2010;Getenet, 2012;Latinopoulos, 2014;Birol et al, 2006). This identifies residents' opinions about current issues and problems related to the mountain, and five attributes (biodiversity, water availability for domestic supply and irrigation, recreational quality, job opportunity and annual cost for service improvements) are selected to describe choke mountain wetland ecosystem.…”

“…This identifies residents' opinions about current issues and problems related to the mountain, and five attributes (biodiversity, water availability for domestic supply and irrigation, recreational quality, job opportunity and annual cost for service improvements) are selected to describe choke mountain wetland ecosystem. The CEM is a variant of conjoint analysis, which was primarily developed by Louviere and Hensher (1982), and Louviere and Woodworth (1983), and has its roots in Lancaster's characteristics theory of value, in random utility theory and in experimental design (Latinopoulos, 2014). According to random utility theory (Luce, 1959;McFadden, 1973), utility function for a The assumption is that stochastic components are independently and identically distributed (IID) with a Gumbel distribution.…”

Ecosystem services have not market price. In Ethiopia, choke mountain wetland ecosystem has major contribution for providing water, regulating climate, and offering recreational. Valuing this natural resource helps to protect it from damage. The objective of the study is to value choke mountain wetland ecosystem by using choice experiment. To value it the attributes are biodiversity, recreational service, water availability, job opportunity, and monetary payment. Primary data was collected from 270 sample households. Both descriptive and econometrics analysis were conducted. The study found that households had good awareness about the choke mountain wetland ecosystem services. Mixed logit models were used for valuation, and all attributes are significant to affect the probability of choosing an alternative scenario. The study found that households gave higher value for biodiversity improvement than the rest and water availability is the least preferable attributes. The total WTP for the first and second alternatives was 7,133,034.216 and 7,031,211.146 respectively; it was high in the second alternative. Moreover, compensating surplus which reflect overall willingness to pay for a change from the status quo to alternative improvement scenarios were estimated. Estimated results for high improvement scenario and medium improvement scenario were ETB 2,119,457.028 and 1,955,828.606 respectively.

“…the choice experiment (CE) method. A large number of studies have been conducted using CE over the decades to examine the welfare effects and consumer preferences attributes for water services (Abou-Ali & Carlsson 2004;Willis et al 2005;MacDonald et al 2005;Hensher et al 2005;Kanyoka et al 2008;Poirier & Fleuret 2010;Latinopoulos 2014).

Water service is usually taken for granted as important amenities with required levels needed, however little is known about how much consumers are willing to pay for particular water service levels. Improved water services should be based on the understanding built upon consumers' choice and preferences. Thus, this study aims to estimate willingness to pay (WTP) of consumers in Terengganu, Malaysia for improvement in domestic water services. A choice experiment method was conducted to assess consumer preferences for water service attributes: i.e. water quality, water disruption, water pressure and water price. Primary data were collected using face-to-face interviews of structured questionnaire from a sample of residents in eight districts in Terengganu. A conditional logit model was carried out for data regression. The results showed significant willingness to pay (WTP) and the contribution of the level of education, age and income in supporting the specific attributes of water services improvements. Identifying the attributes and their prices based on consumers' preferences would help water provider to recognize and deliver preferred water service attributes, effective water tariff policy for cost recovery and water service sustainability to consumers.

“…attitudes or information), taking into account the unobserved variables as another source of difference in the respondents preference can help to obtain better insights on respondents' behaviour (Nunes 2002;Hess and Beharry-Borg 2012). Therefore, estimating non-users' WTP and how their participation is affected by their attitudinal, information or sociodemographic factors can provide useful information for future policy-making (Fonseca 2009;Latinopoulos 2014). This later on and based on utility measure could help the policy-makers to choose the policy with highest utility (Hess and Beharry-Borg 2012;Home et al 2014).…”

A contingent valuation study was conducted to investigate the values of Shadegan International Wetland to the non-current users of this ecosystem. Structural equation modelling (SEM) was employed to model the effect of respondents attitudinal and sociodemographic characteristics on their willingness to pay (WTP). Results showed that respondents' concerns on wetland management, income and education had direct effect on their WTP. Results of non-parametric and binary logit models to estimate WTP showed that respondents were willing to donate US$2.75 and US$3.18 per household per month, respectively. Simulation of results for future scenarios showed that only if income increment would be more than price increase, the market share of better conservation scenarios of wetland will increase. Estimated benefit was compared with opportunity cost of the wetland for other land uses. The results concluded that regardless of enormous benefits of wetland in limitless time, the current benefit of preservation wetland is economically valuable.
