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.

The purpose of this paper is to estimate 'willingness to pay' for mobile data service by using contingent valuation method with double bounded dichotomous choice question. The findings are as follows.: First, the willingness to pay of mobile data service is considerably lower than current retail price. Second, the perceived degree of mobile data service such as awareness and benefit recognition is positively related to the willingness to pay of mobile data service. Our results suggest that active promotion and strengthening of the content of mobile data service are needed in order to enhance the profitability of mobile operators. The analysis results will be used to set the mobile operator's pricing strategy and to build up a successful communication policies in the mobile ecosystem.

조건부가치측정법(CVM)의 지불의사 유도방법인 이중 양분선택형 질문법은 단일 양분선택형 질문 CV자료의 통계적 비효율성을 극복하기 위한 방법으로 제안되었다. 이 방법은 여러 가지 장점에도 불구하고 출발점 편의의 심리학적 근거인 정박효과 (anchoring effect)의 발생 가능성을 의심받고 있다. 그러므로 본 논문에서는 이중 양분선택형 질문 CV자료에서 정박효과를 검토할 수 있는 일반적 지불의사금액모형을 제시하고, 그 모형으로부터 정박효과를 검토할 수 있는 방법을 제안한다. 모형은, Cameron and Quiggin(1994)이 제안한 이변량 모형에 두 번째 내재 지불의사금액의 설명변수로서 처음 제시된 특정금액에 대한 양분선택적 응답결과를 포함시킨 형태이다. 이 모형에서 처음 제시된 특정금액에 대한 양분선택적 응답결과의 계수 부호가 음(-)이고 통계적으로 유의하다면 정박효과가 발생하는 것으로 볼 수 있다. 그러나 만약 이러한 계수 검토에서 정박효과 발생을 확인할 수 없는 경우, 두 번의 응답에서 두 지불의사금액 추정치들의 평균이 다르다고 볼 수 없다면 정박효과를 우려할 필요가 없다. 이 검토 모형 및 방법을 본 연구에서 한강 수질 개선에 대한 CV자료에 적용해 본 결과 정박효과를 우려할 필요가 없음을 확인할 수 있다.

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 evaluated economic value recognized by the residents for the pleasant urban park management using contingent valuation method(CVM) to APEC Memorial Park in Pusan in terms of private fund development for the management of the city park. As a result, the estimated amount payable by each household for the management of APEC Memorial Park in Busan was between 5,673 won and 8,358 won. If such amount is expanded to households in park hosting area, it was 2.2~2.3 times of the park management budget in 2012, which demonstrates the willingness to pay (WTP) of residents for pleasant park was higher than the management budget. Social factors of respondents affecting WTP for city park management operation included age, educational level and income level. Those with high age and high education level had higher WTP. And, WTP was much affected by the use of park and recognition of residents. In particular, those with high frequency in the use of parks had higher WTP, and the users with more than once per week had 1.1 times higher WTP than overall WTP. Then, the satisfaction of park rather than recognition of necessity of park had led to higher WTP. Accordingly, it is necessary to manage park facility management and use program operation to enhance park satisfaction and it is also required to develop a park culture distribution policy to link such recognition to donation.

Recently multifaceted advantages of urban agriculture are emerging in civil society and related policy arena such as food safety, environment, and social welfare. This study tried an estimation of residents' willingness-to-pay for urban farming to examine feasibility of using part of urban green infrastructure as urban farm (e.g. allotment garden). A survey targeting Bundang and Dontan new-town residents was carried out and willingness-to-pay for urban farm rental was estimated by contingent valuation method (CVM). The estimated rent was cross-checked with the rental cost and travel cost paid by hobby farm users in the outskirt of metropolitan area. The result of this study showed that the potential demand for urban farming is ample if urban farms or allotment gardens are planned within new development areas. That is, 72.6 percent of new-town residents questioned had intention of using allotment garden within urban parks and green spaces. Estimated willingness-to-pay for renting a plot, $16.5m^2$ of urban farm, was about 236,000 won(KRW), which is higher than rent for a plot of allotment garden which is located out of city. Variables which were statistically significant to estimated willingness-to-pay for urban farming were sex, age, and occupation of respondents, among other explanatory socio-demographic variables, while expected frequency and duration of visit to urban farm were insignificant.

This study analyzes the economic effect of rehabilitation and upgrading of reservoirs as a prevented method against natural disasters under recent abnormal weather conditions and dam-break. For the analysis, we divide the purpose of rehabilitation and upgrading of reservoirs into the stable supply of rural water under uncertain weather conditions and the prevention of collapse due to the aging of the reservoir. We measure the economic effect of rehabilitation and upgrading of reservoirs by estimating the resident's willingness-to-pay for the project through Contingent Valuation Method(CVM). The result shows that distributions of willingness-to-pay to prevent natural disasters and dam-break are similar to each other. About 66% of the residents in sample regions are willing to pay for the project. The resident's willingness-to-pay to protect natural disasters and dam-break are 32,250 to 46,147 won and 28,427 to 47,308 won respectively on average for all sample regions. The comparison of willingness-to-pay by type of regions shows that paddy field areas are the highest followed by facility cultivation areas and urban areas. In addition, total expected value of the projects calculated based on the resident's willingness-to-pay for paddy field areas and facility cultivation areas are much larger than actual project costs. This implies that rural residents are fully aware of the importance of the project to prevent natural disasters and dam-break and are willing to pay for additional costs if needed.

The purpose of this study was to define the relationship between respondents' social economic condition and willingness to pay on forest landscape. From the result of analyzing the difference of willingness to pay amount with considering social economic condition by using statistical technique, it was found that willingness to pay amount was highest when people are able to access forests landscape. In addition, it was found that women's willingness to pay amount was higher than that of men and the person such as laborer and public employee, who could spare enough time, had the intention to pay higher amount, than the person such as specialist and self-employed person, who spare enough money. For age, it was found that the retired people in their sixties showed low willingness to pay amount on forest scenery. For income per household, it was interesting that although willingness to pay amount increased as income increased, it was rather low in high income class, whose income was more than KRW 10 million.

Although the wine industry continues to grow, little empirical research on consumer preferences has been conducted. Thus, our objective was to analyze consumer views on wine attributes. A choice experiment (CE) was designed to detect a marginal willingness to pay for particular characteristics of wine (balance, flavor, color, clarity, and value-for-money). A questionnaire was administered and 286 responses were received. A multinomial logit model was estimated using the maximum likelihood method. The results indicated that balance, flavor, color, clarity, and price were all important to consumers. The CE data revealed that estimates of marginal willingness to pay were 31,899 won/bottle for balance, 23,088 won/bottle for flavor, 3,230 won/bottle for color, and 25,936 won/bottle for clarity. The balance of a wine was most important, and the flavor, clarity, and color were also significant. The results of this work will be of assistance in promoting the domestic wine industry.

Willingness-to-pay (WTP) for pork produced by quality test was determined using a contingent valuation method. Three model studies including a dichotomous-choice and two double dichotomous-choice types were conducted. The respondents in this study appropriately understood the contingent valuation and the suggested price was significant as a characteristic variable. The results imply that there is lower chance to select pork produced by the quality test, as the price difference is greater between conventional and quality-tested pork. WTPs in double and single contingent valuation models were 735 and 547 won/100 g, respectively. WTP was increased with increasing the educational level of respondents. The average WTPs analyzed by convariate were 1,015 won/100 g for double contingent valuation and 580 won/100 g for single contingent valuation. Considering the minimum price of WTP of pork produced by quality test (547.4 won/100 g), the total economic value was estimated to be 5,173,600 million won and per capita customer value was 106,000 won. Therefore, providing an institutional strategy for pork quality test will be beneficial for the consumers.
