This study was conducted to evaluating the willingness to pay for marine leisure ships through a contingent valuation method that can estimate the value of non-market economy. The questionnaire adopted a double-bound dichotomous choice Model and the variables for evaluating the amount of willingness to pay consisted of demographic variables and respondent behavior variables, and related information verified through previous studies. As a result of collecting and analyzing a total of 309 questionnaires, the amount of willingness to pay for marine leisure ships was estimated to be 25,510 won. In addition, significant variables affecting the amount of willingness to pay were the experience of visiting the island, satisfaction with the introduction of new maritime transportation, and intention to revisit the island. Through this study, it can be used as a basis for evaluating the economic value of new maritime transportation by estimating the willingness to pay for marine leisure ships using the contingent valuation method.

This study attempted to estimating economic value of environmental resource by using the contingent valuation method(CVM), known as one of the tool measuring the economic benefits. To analysis the preservation value of Bong-seo Mt.. the surveys were conducted for citizens resident in Cheonan city. The sample sizes of the survey were 200 respectively. The survey method adopted face-to-face interview method as a mean of correcting useful response. This study considers models for evaluating the willingness to pay(WTP) based on payment card contingent valuation survey data and has attempted to measure goodness of fit for the data obtained from the survey design. It was estimated that the average WTP of Cheonan citizens for a maintenance and management of Bong-seo Mt. was 5,010 won per month and 60 ,118 won per year. When it is translated by total number of households in Cheonan city, there is the preservation value of approximately 8.8 billion won per year. On the other hand, total expense of development increased about 1.7 times over including application of the preservation value.

Traffic congestion causes enormous social costs as well as loss of travel time and waste of energy. Though the Seoul metropolitan government implemented various forms of transportation policies such as urban road pricing and public transportation reform, traffic volume which across the Seoul metropolitan borders have greatly increased because of housing land development in suburban area. The purpose of this study is to estimate individual's willingness-to-pay(WTP) for extensive implementation of congestion pricing through policy-mix with bus rapid transit(BRT) system. So the field survey interviews carried out. The empirical analysis was done with priority given to the following two topics; derivation of individual WTP and prior evaluation of policy effect from the equity aspect. To estimate individual WTP, we adopted contingent valuation method (CVM). The former is to estimate individual WTP for respondent's maintaining his/her transit pattern when he/she is faced with congestion pricing by using compensating variation(CV) concept. And, the latter aims at evaluating policy effect from the equity aspect by calculating the Proportion of WTP to average income using WTP in income bracket for policy scenarios.

The dichotomous-choice contingent valuation method is applied to estimate the landscape value of Jeju Island's stonewall fencing farming land. A distribution-free approach, Turnbull empirical distribution model, is employed to solve negative willingness to pay and truncation problems. The data used are collected from the interviews with tourist about willingness-to-pay at the various donation amount levels of Jeju stonewall's landscape value. The evaluation result is shown that the average amount of willingness to pay for the Jeju stonewall fencing farming land is 3,001 won per meter with standard deviation of 511.0 won/m.

In this paper, we apply fuzzy theory in a discrete choice Contingent Valuation Method(CVM) in order for dealing preference uncertainty problem. Fuzzy membership function is used in an empirical analysis to estimate the willingness-to-pay(WTP) for the preservation of the endangered Asiatic Black Bear in Korea. The estimated WTP was about 9,090 Korea Won per household with 78 percent of confidence level. The advantage of applying fuzzy theory in the valuation method could be found in its ability to measure the confidence level of the estimated WTP.

Even though consumers' concern about food-safety certified or environment-friendly chicken meat becomes one of the main issues of food consumption in Korea, university students' interest about food-safety certified or environment-friendly chicken meat was not often discussed. We realized that the cafeteria of university is one of the largest consumption points for the chicken meat of university students, and tried to analyze university students' consumption of food-safety certified or environment-friendly chicken meat at the cafeterias of university. The object of this paper is to conduct survey analysis about the students' behavior for consumption of food-safety certified or environment-friendly chicken meat at the cafeterias of university and to measure WTP(Willingness-to-pay) for the food cooked with food-safety certified or environment-friendly chicken meat. The results present that most of students show higher preference of environment-friendly chicken meat than food-safety certified chicken meat, and that they can pay 1,329.9 Korean won for food cooked with environment-friendly chicken meat.

The aim of this study was to analyse the cost-benefit-ratio of a soil remediation project. The target of the study was the 'Altablagerung Osnabrueck-Wueste' the largest inhabited former landfill site in Germany. The determination of benefit resulting from the soil remediation was quantified with the help of willingness-to-pay(WTP) analysis (contingent valuation method, CVM). 400 households participated in the survey. The average WTP was 6.5 Euro per household per month or 78 Euro per house-hold per year. The projected benefit generated by the remediation (consumer value) for the population in the landfill area was determined to be 0.7 million Euro per year. Factors which influence the will-ingness to pay were evaluated. The most important factors were age, garden use and the prevailing concern about personal health. A computation of the cost-benefit relationship was made on the basis of three different scenarios, which differed in terms of the projected benefits. Finally the economical efficiency of the project was determined. With a projection of 18 years and upwards the remediation of the soil is economically worthwhile.

The contingent valuation method (CVM) is one of the most commonly used and effective methods to evaluate non-use value of resources. Reasonable application of CVM to value the cultural heritage is the key process of evaluation. CVM was used to evaluate the non-use value of cultural heritage of Taishan Mountain combined with questionnaire survey and field research in this study. The results indicated that the importance of the degree of the three components of non-use value was heritage value ranked highest (40.22%) > followed by existence value (38.58%) >then option value (21.20%). In addition, the rate of willingness to pay was 54.52%, the average and median values of per person were 40.17 CNY·a^-1 and 20.00 CNY·a^-1 and the non-use values of Taishan Mountain cultural heritage was 33 million CNY·a^-1. The median value of WTP was consistent with Asian countries but was lower than European and American countries. Factors influencing WTP showed that monthly income and satisfaction with Taishan Mountain were correlated to WTP, and family location and willingness to revist were correlated remarkably with WTP. In addition, monthly income was correlated remarkably with WTP value, however other factors were not. The results showed the importance and necessity of protective development of Taishan Mountain cultural heritage, which would be used as an important reference for decision makers.

The purpose of this study is to analyze the effect of local area concentration of particulate matter on life satisfaction, by matching subjective satisfaction in the Korea Labor & Income Panel Study data with daily data of $PM_{10}$ and $PM_{2.5}$. We find that the concentration of particulate matter has a significant negative effect on satisfaction. A $1{\mu}g/m^3$ increase in $PM_{10}$($PM_{2.5}$) leads to lower the probability of choosing 'satisfaction' by 0.042%p~0.091%p(0.034%p~0.153%p) and a 1% increase in annual income per household raises the probability of choosing 'satisfaction' by 0.16%p~0.18%p respectively. To estimate the monetary value of reducing $PM_{10}$ and $PM_{2.5}$, we calculate willingness-to-pay for mitigating air pollution, which represents the tradeoff between the reduction in particulate matter and income. We find that people on average are willing to pay \108,787($96)~209,519($186) for a $1{\mu}g/m^3$ reduction in $PM_{10}$ and to pay 89,345($79)~362,930($322) in $PM_{2.5}$. This amount corresponds to 0.26%~0.50%(0.22%~0.88%) of the average annual household income in South Korea.

Although coal-fired power generation has played a role as base load unit, it has incurred various social costs in the process of generating and providing electricity. It is necessary to extend the proportion of low-carbon power generations, and reduce the ratio of coal-fired power generation to cope with global climate changes. This study, therefore, attempts to estimate the public's willingness-to-pay (WTP) for substitution of supplied electricity from hydro-electricity generation, a representative renewable energy, for coal-fired power generation. To this end, we apply the contingent valuation (CV) method, widely used technique when valuing non-market goods, to elicit the public's WTP. In addition, a spike model is employed to consider zero WTPs. After the empirical analysis with 1,000 households CV survey data, the results show that mean household's WTP for replacing supplied electricity from hydro-electricity generation with coal-fired power generation is estimated to be about 54 KRW per kWh. The results of this study are expected to contribute to determining energy-mix and provide benefit information of hydro-electricity generation.
