Mangrove, as one of the most unique ecosystems, is a great natural resource potential with high productivity and biodiversity able to adapt to harsh areas between the sea and coast. Its destruction rate is very mild as it is estimated to 1% each year (Ong et al., 1991) and 0.7-3% per year (Pedleton et al., 2012). The destruction of mangrove is usually related with human population density (Alongi, 2002). Widespread mangrove destruction affects the loss of biodiversity and other resources and the functioning of the ecosystem. The huge potential of mangrove must be preserved by managing, maintaining and providing costs to protect and improve ecosystems. This study aims to measure Kuala Langsa community members’ willingness to pay for the preservation and repairationof degrading mangrove. To achieve this goal, Contingent valuation methods was used in this study. Of the 131 respondents involved in this study, 112 or 85.496%  are willing to pay for the preservation of mangrove. While those unwilling to pay account for 19 or 4.504% . WTP with the households 669 earned by  is Rp 18,821,512,200/month or Rp 225,858,146,400/year.

Contingent Valuation Methods

Some of the implications of ethical preferences for traditional welfare analyses of existence values are discussed in this paper and illustrated with a lexicographic model for preference structures. Although willingness-to-pay and willingness-to-sell are well-defined, their connection with Hicksian surpluses is lost when a person is motivated by an ethical commitment to others’ welfare. Researchers need to expand contingent valuation methods to collect information on underlying motives and types of preferences in order to identify respondents who fit the neoclassical model of egoistic man.

Contingent Valuation Methods

This research study investigates the market and non-market benefits and costs of adopting a forest resources policy aimed at environmentally responsible purchasing at a large university. I use benefit-cost analysis and contingent valuation methods to determine the population's willingness-to-pay (WTP) for environmentally responsible forest products. Econometric analysis reveals that past WTP and belief that the forest resources policy will improve the environment positively affect WTP, while position as a staff member decreases WTP. This methodology can be used for other products that have non-market values like cafeteria compost and by other large purchasing entities such as corporations and government agencies.

Objective - The focus of this research is the analysis of vulnerability and factors that influence willingness to pay (WTP) to cope with flood. Other result of this research is economic valuation of flood impact on paddy field in particular. Methodology/Technique - This research used the descriptive and quantitative method. Its data were collected through direct interviews with 380 respondents. Its samples were scattered in 11 sub-districts and 94 villages. The representatives of each village were 4 respondents, by adding two respondents from Wedi Sub-district and 2 respondents from Cawas Sub-district. Proportional sampling technique was employed to determine the research samples with criteria: very close (<50 m), close (50-100 m), and far (> 100 m) from the river. Its data were analyzed by using contingent valuation methods (CVM). Findings - The results of the research are as follows. Many activities have been implemented to mitigate flood in Klaten Regency, but many problems have been encountered due to the limitations of Government Budget (APBD). The variables of income of family/household, water level, distance, and loss have a significant effect on the WTP. In majority, the respondents (72.27%) have the WTP for flood mitigation activities with the average WTP of 15,391 IDR. Novelty - Economic valuation of flood mitigation programs and activities is required as to further enhance the role of the community, taking into account factors affecting the WTP. The local government should take advantage of the public's WTP to support flood mitigation activities among neighbourhood, village, sub-district and regency. Type of Paper: Empirical Keywords: Vulnerability; Flood Mitigation; Contingent Valuation; Willingness to Pay (WTP). JEL Classification: D12, H84.

The environmental drivers of species distributions and abundances are at the core of ecological research. However, the effects of these drivers on human abundance are not well-known. Here, we report how net primary productivity, biodiversity, and pathogen stress affect human population density using global ethnographic hunter-gatherer data. Our results show that productivity has significant effects on population density globally. The most important direct drivers, however, depend on environmental conditions: biodiversity influences population density exclusively in low-productivity regions, whereas pathogen stress does so in high-productivity regions. Our results also indicate that subtropical and temperate forest biomes provide the highest carrying capacity for hunter-gatherer populations. These findings document that environmental factors play a key role in shaping global population density patterns of preagricultural humans.

Contingent Valuation Methods

Approximately 20 years ago, Peter Diamond and I wrote an article for this journal analyzing contingent valuation methods. At that time Peter's view was that contingent valuation was hopeless, while I was dubious but somewhat more optimistic. But 20 years later, after millions of dollars of largely government-funded research, I have concluded that Peter's earlier position was correct and that contingent valuation is hopeless. In this paper, I selectively review the contingent valuation literature, focusing on empirical results. I find that three long-standing problems continue to exist: 1) hypothetical response bias that leads contingent valuation to overstatements of value; 2) large differences between willingness to pay and willingness to accept; and 3) the embedding problem which encompasses scope problems. The problems of embedding and scope are likely to be the most intractable. Indeed, I believe that respondents to contingent valuation surveys are often not responding out of stable or well-defined preferences, but are essentially inventing their answers on the fly, in a way which makes the resulting data useless for serious analysis. Finally, I offer a case study of a prominent contingent valuation study done by recognized experts in this approach, a study that should be only minimally affected by these concerns but in which the answers of respondents to the survey are implausible and inconsistent.

Contingent Valuation Methods

Does willingness to pay a premium for local specialty food products differ between consumers in Maine, New Hampshire, and Vermont? Two food categories are investigated: low-end ($5) and high-end ($20) products. Premia estimates are compared across states and across base prices within states using dichotomous choice contingent valuation methods. Results suggest that the three states of northern New England have many similarities, including comparable price premia for the lower-priced good. However, there is some evidence that the premium for the higher-priced good is greater for the pooled Vermont and Maine treatment than for the New Hampshire treatment. Vermont and New Hampshire residents are willing to pay a higher premium for a $20 than for a $5 food item, while the evidence suggests that Maine residents are not.

The research aims at estimating the level of Willingness to Pay of the tourists for the Tourism Attraction of Jatijajar Cave in Kebumen Regency. The primary data is obtained from 105 respondents by using the Multistage Sampling and five key persons by using the Purposive Sampling. The characteristics of respondents show that some of the tourists are male, around 21 to 30 years old. The result of Contingent Valuation Methods shows that the WTP of the tourists of Jatijajar Cave has the average about Rp 17,000.00 and the total value of WTP is about Rp 5,231,410,000.00. The novelty in this research is using Contingent Valuation Methods approach to educate the visitors through the hypothetical-market that has been built by two scenarios of willingness to pay for the visitors at Jatijajar Cave tourism attraction as a compensation for the development of tourism attraction.

This study sought to determine farmers’ willingness to pay (WTP) for 2-wheel tractor hiring services in Northwestern Ethiopia. Survey questionnaire related to CVM was designed and face-to face interview were made to collect the data. Moreover, focus group discussion used to generate qualitative information on household characteristics. Both purposive and stratified sampling techniques were used based on gender, wealth class and soil type of the sampled households. For the study, a total of 144 farm households were considered using double bounded contingent valuation methods approach with an open-ended follow-up question. The study result indicated that the mean amount of money farmers is willing to pay was 1121.026 ETB (56.05 USD) per hectare. Econometric results confirm that the education level of households, land size of households, male labor availability and soil type were the factors that affecting the farmers’ level of willingness to pay positively. However, age of households and tropical livestock unit (TLU) were the factors that affected the same negatively. About 80% of the sampled farmers were willing to use 2-wheel THS. The finding of this study showed that farmers demand for improved 2-wheel THS is high. Hence, there is a need to consider the above factors to introduce 2-wheel tractor hiring service for cultivation practice in the study area.
