This study evaluates the economic benefit of the project constructing the international riding arena having been built at Sangju in Gyeongsangbuk-Do by the willingness to pay (WTP) of residents in the province. As the evaluation method, the dichotomous choice contingent valuation method (CVM) is adopted with the additional questions of whether his/her WTP is zero, to improve the statistical accuracy of evaluation results. Considering the arena's administrative location, the population of the surveys for analysis is confined to residents of Daegu and Gyeongsangbuk-do. The survey is conducted through personal interviews. It turns out that the WTP per household per year is evaluated as 1,847 won and the total yearly benefit of the Sangju international horse riding arena is estimated as 3.56 billion won.

As the aged and physically disabled people are expected to increase in the next several years, traffic demand especially for the 'mobility handicapped people' will be stronger. According to this trend, our society needs the improvement of social overhead capital for the aged and the disabled. First of all, Barrier-free of public transport facilities is urgent case. The purpose of this study is to estimate value of the Barrier-free facilities at subway stations by using Contingent Valuation Method(CVM) with Double Bounded Dichotomous Choice Question and to analyze the factor which affects the WTP(Willingness To Pay) of subway users by using Survival Analysis. As a result of this study, 'Elevators' and 'Escalators' are higher than 'Handicapped Gate Machines' and 'Ramps for Wheelchair' in the aspect of the average willingness to pay. Therefore the government is recommended to install the Barrier-free facilities for going up and down such as 'Elevators' and 'Escalators', and then supply others for just using subway, and passing such as 'Handicapped Gate Machines' and 'Ramps for Wheelchair'. Also, the average willingness to pay of 'mobility handicapped people' is higher than that of 'normal people'. It indicates that 'mobility handicapped people' value each Barrier-free facility high compared to 'normal people'.

The National Land Census Project aims to survey the national land regularly to resolve the land category disagreement and reflect the actual land use. The objective of this study is to investigate whether not only the National Land Census Project but also related land and housing surveys bring about the improvement of social welfare in light of the invested budget, and to measure the project feasibility. The potential benefit after the National Land Census Project is not traded in the market. To determine the economic value of this potential benefit, the Contingent Valuation Method was used. This study utilized the single-bounded and double-bounded dichotomous choice models simultaneously to estimate the project feasibility of the cadastral system improvement. According to this study, cost-benefit ratio of the project was estimated larger than 1, which means that social benefits are larger than social costs.

The purposes of this study are to estimate mean willingness to pay (WTP) for preventing forest fires by contingent valuation method (CVM), and to calibrate the variables affecting WTP. The forest fire prevention fund was utilized as a payment vehicle to elicit respondents' willingness to pay (WTP). A total of 500 adults who reside in Seoul Metropolitan area were selected by two-stage cluster sampling and conducted the face-to-face interview. The scenario was designed to meet the requirements for double-bounded dichotomous choice CVM. More than half of the respondents (64.6%) have a willing to pay for the fund. The mean WTP was \4,532. Therefore a total WTP for the population was \34,165,758,000. The calibration of Weibull proportional hazard model showed that education level, environmental conservation intention and negative consciousness about the effect of forest fire were independent variables strongly influencing the WTP.

This study aims at estimating the consumer's demand and willingness to pay(WTP) for horse meat in Korea. Three econometric models are employed to examine the multiple layers of the demand, including the current demand, the potential demand and latent demand. Findings indicate a substantial demand for horse meat. Dichotomous choice contingent valuation method is used to elicit the WTP. We assess the mean WTP for horse meat using a double-bounded logistic model. As a result, consumers are willing to pay at 67.8 percent of the beef prices of the third quality grade to purchase horse meat. And, for the factors that influence on WTP, only sex, age and recognition of horse meat are statistically significant.

As interest in 'Forest therapy' continues to increase, local governments as well as Korea Forest Service (KFS) are actively promoting a project to create 'healing forests' nationwide. In this situation, it is necessary to examine whether such a policy is suitable. Therefore, the main purpose of this study is to estimate the use value of Jangseong healing forest which is the most-visited place among the national healing forests. To achieve this aim, a survey of randomly selected 400 visitors was conducted in Jangseong healing forest. 391 surveys were used for analysis, excluding 9 untruthful answers. And 1.5 bounded dichotomous choice contingent valuation method (CVM) was used to estimate the economic value of Jangseong healing forest. As a result, the average willingness to pay ($wTP_{mean}$) for the use fee of Jangseong healing forest was 35,010 won per visitor per day. And the annual use value of Jangseong healing forest was estimated to be worth almost 7.5 billion won.

It is time to develop new renewable energy that could fundamentally replace fossil fuel, which has been increasingly needed due to environmental pollution and energy security. Korean marine bio-energy development project is planned to produce 50% of total bioenergy. This study attempts to measure the greenhouse gas emission reduction benefits of marine bio-energy development project through contingent valuation method. Single bounded dichotomous choice (SBDC) is applied with spike model. The results show that the average willingness to pay are estimated to be KRW 4,190 at SBDC, per household per year. If the result has been expanded to the region which is survey conducted, KRW 50.1 billion annually. These quantitative information can be usefully utilized in the cost benefit analysis to implement project and policy-making for the industrialization of marine bio-energy development project.

The critical temperature and the rate of increase in excess death caused by heat waves in the age group of 65 years and older are derived. The value of statistical life method was used to quantify economic damages, and the willingness to pay after 71 years of age for 10 years was measured based on the dichotomous choice contingent valuation method survey. The result shows about KRW 481,110,000 is required annually to reduce the possibility of death by climate change to 1/1000.

This study evaluates citizen's willingness-to-pay for the benefits from improved water quality of the Taehwa river in Ulsan, Korea, using a contingent valuation method with double-bounded dichotomous choice. The estimation results of the bivariate probit model shows the amounts of willingness-to-pay are monthly 3,458.5 Korean Won per household and yearly 14,760 million Korean Won for total households in Ulsan, Korea. These estimates are equivalent to the social values of improved water quality of the Taehwa river. This study also tests the inter-dependence between two answers, which may occur in the responses of the questions for the double-bounded dichotomous choice, and all the null hypotheses on the inter-dependence are rejected in this study.

Recently, the problem of noise has received much attention in the urban environment. This paper attempts to measure the economic benefits of urban noise reduction in the metropolitan area. To this end, the dichotomous choice contingent valuation method is applied. In particular, recently proposed one and one-half bound model that reduces the potential for response bias in the double bound model while maintaining much of its efficiency. We surveyed a randomly selected sample of 800 households in the metropolitan area and asked respondents questions in person-to-person interviews about how they would willing to pay for the noise reduction. Respondents overall accepted the contingent market and were willing to contribute a significant amount (997 to 1,778 won), on average, per household per month. This willingness varies according to individual characteristics such as concerns about noise, dwelling area, and income. The aggregate value of the noise reduction in the sampled metropolitan area amounts to approximately 79.26 to 141.35 billion won per year.
