        전 세계 해양의 대부분을 차지하는 공해는 해양바이오산업 성장에 필수적인 귀중한 해양 자원을 보유하고 있다. 이러한 글로 벌 노력의 최전선에는 한국의 공해 자원 확보 및 기초효능(기초물질) 탐사사업이 있다. 이 연구는 대중의 인식을 측정하고 프로젝트의 이 점을 정량화하여 향후 정책 결정에 대한 통찰력을 제공하고자 했다. 결과에 따르면, 연평균 지불의사액(WTP)은 3,778.8원으로, 전체 국민 으로 확장하면 약 815.4억 원에 해당하는 것으로 나타났다. 본 연구의 의미는 두 가지이다. WTP를 기반으로 공해상 해양생명자원 확보의 경제적 가치는 연간 약 815억 원에 달할 정도로 상당하다. 이는 투자에 대한 WTP를 고려할 때 향후 정책 수립을 위한 중요한 참고 자료 로 제공 가능하다. 해양생물자원에 대한 관심이 높아지고 있는 반면, 대중의 인식은 상대적으로 낮은 편이다. 그러나 본 사업은 해양바이 오산업에 필수적인 데이터베이스를 구축하고 국제 해양생물자원을 확보하는데 있어서 중요한 역할을 하고 있다. 대중의 관심과 지속적인 지원은 이 사업 뿐만 아니라 향후 정책 구현에도 매우 중요하다. 대중의 인식을 높이는 전략은 필수적이며, 연구 결과는 향후 정책 결정 에 귀중한 의견을 제공한다.

        The purpose of this study was to estimate the economic values of whale watching. The data used in this study were collected with 1,599 coastal tourists and the questionnaire included contingent valuation method questions. The results show that coastal tourists obtained the benefits of about KRW 15,970 from whale watching. Further analyses were conducted to check the differences of willingness to pay for whale watching based on the three variables as follows: previous experience of whale watching and participation intention in whale watching tourism, and previous experience of cruise trips. The results indicate that the respondents, who already participated or intended to participate in this type of tourism activity, were willing to pay higher than those, who did not participated or had no intention of participation, respectively. These results imply that whale watching could be a feasible alternative to the direct consumption of whale meat. Based on the study results, we provide policy and management-related implications for whale watching programs.

        The Korean government has been carrying out the marine ranch development project since 1998 with the purpose of responding to the decrease in coastal fishery resources and fishery income, preparing a systematic management system for the sustainable use of fishery resources and realizing advanced fisheries power by expanding and upgrading fisheries resource development projects. In addition, the government established the Korea Fisheries Resources Agency and promoted projects for the protection and management of fishery resources by increasing basic productivity by artificially creating marine forests in areas where whitening events occur. Since the project of building marine ranches and marine forests requires immense government financial support, it is important to estimate the economic value and thoroughly evaluate the feasibility of the project. In this paper, the project of non-market economic value of the development of marine ranches and the development of marine forests was estimated. CVM (Contingent Valuation Method) was applied as a methodology for benefits estimation. Prior to the analysis, a one-on-one interview survey was conducted with participation of 512 residents and 514 residents respectively for the project of creating a marine ranch and developing a marine forest. A DBDC (Double-Bounded Dichotumous Choice) model was applied in the WTP (Willingness To Pay) analysis model and the socioeconomic variables of the surveyor, such as sex, age, education and income, were reflected in the model. The economic benefits from the two projects, namely, building of marine ranches and developing marine forests were estimated to be equal to 4,608 won and 7,772 won per household per year, respectively. According to the results of the survey, it seems that respondents think that marine forests are more valuable than marine ranches. This is as a result of ordinary citizens’ thought that the marine ranches are more cost-effective than the marine forests. The benefits estimated through this study can be used for analysis of economic feasibility prior to carrying out the project of building marine ranches and developing marine forests, and are considered to be the valuable for policy-making purposes and finding social and economic consensus.

        This study is to compare and evaluate the estimating method of WTP(willingness to pay) for the valuation of oceans and fisheries resources with non-market goods characteristics using contingent valuation method. In general, when estimating parameters of the WTP function, we should take into account the assumption of probability distribution, inclusion of covariates, method of inducement of payment, and the treatment of 0 payment intention and resistance responses. This study utilizes survey data that was used to estimate the value of fisheries resource protection zones, with a total of 1,200 samples. The main results of this study are summarized as follows: First, the final willness to pay amount is estimated at a statistical significance of less than 1 percent, and the distribution of the final willness to pay amount is from ₩6,926 of the double bounded dichotomous model to ₩10,721 of the spike model. Second, the willness to pay amount based on assumptions about the normal and logistic probability distributions are estimated to be ₩9,429 and ₩9,370 respectively, so there was no significant difference. Third, the willness to pay amount of the single bounded dichotomous model and the double bounded dichotomous model are estimated to be ₩8,951 and ₩6,926 respectively, making a relatively large difference. Fourth, the willness to pay amount of the model without covariates and the model with covariates are estimated to be ₩9,429 and ₩8,951, respectively, so the willness to pay amount is underestimated when the covariates are included. Fifth, the Spike model that considers zero payment intention and resistance response estimates ₩10,405 as the highest payment in this study. Finally, the CVM analysis guidelines proposed by the Korea Development Institute (KDI) are estimated to be ₩9,749 and ₩10,405 respectively, depending on including no covariates and with covariates. Compared to other models, the final willness to pay amount is not estimated underestimated. Therefore this study suggests the use of KDI's guidance under government public policy projects. In view of these results, the estimating model for willness to pay amount model will be selected by considering the sample size, the suitability of the model, the sign of the estimated coefficient, the statistical significance, the ratio of the zero payment intention and the payment rejection. And, for CVMs on government public policy projects, it is desirable to estimate by the method proposed by the KDI.

        PURPOSES: This study was initiated to estimate the benefits from the campaign to prevent drowsy driving crashes on expressways. The study was conducted by the Korea Expressway Corporation using a contingent valuation method. METHODS : First, a questionnaire was designed for a preliminary survey. From the survey’s results, the initial willingness to pay for the campaign was determined by averaging different amounts of payments chosen under virtual scenarios in the survey. The willingness to pay data was used to find a first bid price for the open-ended method used for the second survey. After that, a primary questionnaire was designed and conducted using a single dichotomous choice question (SDBCQ). Drivers at expressway resting areas were asked their willingness to pay for the campaign. Based on statistical analysis using data collected from the second survey, the mean willingness to pay was estimated using a probability utility function. Finally, the benefit from the campaign was calculated using the estimated willingness to pay and accident data on expressways. CONCLUSIONS : Based on the result from the contingent valuation method, the benefit from the campaign to prevent drowsy driving crashes was estimated to be 170.6 won per expressway trip. The benefit is to be paid as an additional toll. In addition, the traffic crash cost estimate is about 2,209,680,000 won less than the cost during the same period in 2014.

        본 연구는 전국의 686개 농가에 대한 설문조사를 통해 농가의 GM 기술과 GM 작물 및 이를 활용한 사료에 대한 인식, 농가의 생산 현황과 속성을 바탕으로 농가의 GM 벼 (쌀)와 GM 사료작물에 대한 기술 수용성을 분석하였다. 개 별적인 농가 속성에 따라 수용 의사가 다르지만, 2개의 GM 기술 수용성 추정에서 공통적으로 GM 기술 수용 의 사를 높이는 변수는 GM 농작물의 필요성에 대한 인식과 잡곡이나 조사료 재배여부로 나타났다. 평균적인 경종 농 가의 경우 7.8% 유의수준에서 농가소득이 47% 증가할 경 우 벼 (쌀)에 대한 GM 기술을 수용하고, 벼 (쌀)를 제외한 사료작물의 경우에는 14.1% 유의수준에서 농가소득이 43% 증가할 때 GM 기술을 수용하는 것으로 분석되었다. 벼 (쌀)와 비교해서 사료 작물은 상대적으로 적은 소득 증가 에도 불구하고 수용 가능성이 나타났다. 그러나 두 가지 경우 모두 통계적 유의성이 5%를 넘어가 신뢰도에 문제가 있다. 앞으로 GM 기술에 대한 신뢰성이 높아짐에 따라 CVM에서 발생하는 가상적 편의가 줄어든다면 통계적 유 의성이 높아질 것으로 기대되므로 이에 대한 추가 연구가 필요하다.

        The paper is to estimate willingness-to-pay (WTP) for tap water quality improvement in Busan, using parametric approach in contingent valuation method(CVM). For parametric approach linear logit model and log logit model are employed in double-bounded dichotomous choice format of CVM. For the reliability and the validity of contingent valuation method a survey was conducted for 665 respondents, who were sampled by stratified random sampling method, by personal interview method. The result of mean WTP for the tap water quality improvement in Busan was estimated to be 3,687 won and 3,660 won per month per household, while median WTP being 1,884 won and 1,892 won per month per household, respectively by linear logit model and log logit model. Provided that our sample is broadly representative of the Busan’s population, an estimate of the annual aggregated benefit of residential water improvement for all Busan households is approximately 29.7 billion won to 29.8 billion won based on median WTP.

        In accordance with the 1996 London Protocol, the marine dumping of wastewater generated from food was totally banned from 2013. Therefore, establishing a food wastewater bio-gasification facility for stable and continuous food wastewater treatment is necessary. The biogas produced from the wastewater can be used as fuel for electricity generation or for heating in power plants and can be sold as gas in cities as well as fuel for vehicles after undergoing a refining process. Thus, the South Korean government is trying to expand the bio-gasification facility of wastewater generated from food. In this study, we try to obtain information about the public value of such an expansion. For this purpose, the household willingness to pay (WTP) for the expansion is determined by applying the contingent valuation (CV) approach. A total of 1,000 South Korean households were involved in the CV survey, which had questions with dichotomous choices. The mean yearly public value WTP for expansion is estimated at 2,564 KRW per household. If this WTP is extrapolated from the sample to the nation’s population, the expansion in the national value is worth 50.1 billion KRW per year. These results indicate that the expansion of food wastewater bio-gasification facility is supported by Korean households.

        As economic growth and development of the living standard causes increasing production of organic waste, the desire to take advantage of organic waste to produce energy is also increasing. Organic waste-to-energy can contribute to improving energy independence through domestic energy security as well as improving the environment by reducing the need for landfills. This paper attempts to quantitatively analyze the non-market benefits arising from the organic waste-to-energy policy. To this end, we apply a contingent valuation (CV) that is most widely used to measure the nonmarket benefits. As for the willingness to pay (WTP) elicitation method, we employed the one-and-one-half-bounded dichotomous choice (DC) model, which produces higher statistical efficiency than the single-bounded DC model and yields greater consistency than the double-bounded DC model. In the CV survey result of 1000 Korean households, a total of 586 households (58.6%) revealed zero WTP. This implies that the use of the mixture model to deal with zero WTP responses was a suitable approach in our study. The yearly mean WTP was computed as KRW 3598 for the next ten years per household, which is statistically significant at the 1% level. Expanding the value to the national population gives us KRW 67.3 billion per year and this value demonstrates the non-market benefits of the organic waste-to-energy policy. This quantitative information could be utilized as a significant reference in the implementation of the organic waste-to-energy policy.
