The objective of this study was to estimate social cost on rehabilitation of existing water pipes by investigating the willingness-to-pay (WTP) of residents at INJE County to avoid the loss and inconvenience of transportation and business resulting from the sudden failure and leaks of old water pipes. Contingent valuation method was used through conducting survey to 180 residents in Inche County, with questions of double-bounded dichotomous choice. The resulting WTP of residents at Inche was 7,682 won/month/household. The annual social cost could be estimated as 960 million won, which might be caused by the failure of the old water pipes at INJE County.

이 논문은 대기오염 개선에 따른 부수적 가치를 분석하기 위하여 가상가치평가법을 이용하였으며, 지불의사 유도방법으로는 이중 양분선택법을 적용하였다. 온실가스의 감축, 특히 이산화탄소 감축은 화석연료의 사용감소를 통해 대기오염물질의 감소라는 부수적 효과를 갖는다. 주요 분석결과를 정리하면 다음과 같다. 첫째, 대기오염 개선에 따른 부수적 가치는 연간 329,236원으로 분석되었다. 둘째, 지불의사금액의 가치 추정에 있어 사회 경제적 특성변수와 환경에 대한 인식을 포함한 분석모형의 적합성이 다소 개선되는 것으로 나타났다. 따라서 제시금액뿐만 아니라 사회 경제적 특성변수들을 포함한 분석모형을 적용하고 이를 통한 지불의사금액의 가치가 보다 타당할 것으로 판단된다.

A project to build a large oceanographic research ship was proposed to improve the level of ocean research. This paper attempts to measure the non-market benefits of the project. To this end, the dichotomous choice contingent valuation method is used. In particular, the recently proposed one and one-half bounded model is applied. The model can reduce the potential for response bias compared to the double bounded model, while maintaining much of its efficiency. Moreover, in order to deal with zero WTP observations, a spike model is adjusted for our data. A survey of 500 randomly selected households was implemented in the Metropolitan area. The respondents were asked in person-to-person interviews about how they would be willing to pay for implementing the project. Overall, respondents accepted the contingent market, and were willing to contribute a significant amount (3,244 won), on average, per household per year. The aggregate value of the project nationwide would amount to approximately 40.1 billion won per year.

The main purpose of this study is to estimate willingness to pay (WTP) by the general publics, assuming that they pay tax or charge for protecting marine living resources and environment through developing and supplying biodegradable fishing nets. This study employed a contingent valuation method (CVM) which is an econometric method. The survey was conducted by using both double-bounded dichotomous choice and open-ended survey. Tobit model was used for the analysis. The variables included concerns about marine environment and fishing net discarded, sex, age profile, number of family members, educational level and personal disposable income. Annual average WTP per family for the biodegradable fishing net development and supply was estimated at 5,294 won and national WTP amounted to some 84.2 billion won. This includes both of use and non-use value of biodegradable fishing nets.

The paper is to estimate the economic value of ecotourism in Anmyeondo tidal wetlands using a double-bounded dichotomous choice (DBDC) model of the Contingent Valuation Method (CVM). For the reliability and the validity of CVM a survey was conducted for 511 visitors by personal interview method in Anmyeondo during August 2000, and respondents were asked for maximum Willingness-To-Pay (WTP) to buy a ticket fer the tidal flat's ecotourism. Overall, respondents answered that they would be willing to pay 55,879 won for a ticket under the study. All equations and results estimated are statistically significant at the 1% or 5% level. For the aggregation of WTP estimates, the sample values are extended to the total annual number of visitors in Anmyeondo area during 1998. A conservative estimate, which considers the calibration factor (0.5) recommended by NOAA (1994) and a positive response rate (83.17%), is 73 billion won.

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.

The public value of agriculture and rural areas is closely associated with the concept of multifunctionality of agriculture and rural areas, which in turn signifies economic values other than the production function of agriculture and rural areas. Based on the survey results, virtual scenarios were set up and the contingent valuation method (CVM) was used to estimate the amount consumers are willing to pay (WTP) for the public functions of agriculture and rural areas. This study selected five domains of the public value (environment conservation, maintenance of landscape and cultural tradition, enhancement of national prestige, local community maintenance and socio-economic functions, and food security) and 21 value items as components of the public value. An economic assessment of the public value of agriculture and rural areas was conducted using a binomial logistic regression model. The estimation results showed that the public value consumers are willing to pay ranges from a minimum of 6,346.8 billion won to a maximum of 9,327.2 billion won.

우리나라 정부는 해양 오염원의 관리와 해양생태계 개선을 위해 해양환경 위해성 평가 및 관리기술 개발사업을 추진 중이다. 그러나 이 사업에는 막대한 예산이 소요되므로, 본 기술의 편익을 정량적으로 분석한 후 사업의 경제적 타당성 여부를 평가해야 한다. 이에 본 연구는 CVM을 활용하여 엄밀한 경제이론에 근거하여 해양환경 위해성 평가 및 관리 기술의 편익을 정량적으로 규명하고자 하였다. 분석결과 해양환경 위해성 평가 및 관리 기술을 위한 연간 가구당 평균 지불의사액은 2,663원으로 나타났다. 이를 전국의 전체 가구로 환산하여 경제적 총편익을 구한 값은 연간 462.82억원이었다. 이 값을 활용하여 해양환경 위해성 평가 및 관리 기술의 경제성 분석을 하였더니 비용편익비율의 하한값이 1.76으로 1을 초과하여 본 사업은 경제적으로 타당성이 존재한다고 판단되었다.

본 연구에서는 가치추정방법의 하나인 조건부 가치측정법(Contingent Valuation Method : CVM)을 이용하여 교통사고 긴급통보시스템 도입을 위한 지불의사액을 산정하고자 하였다. 분석을 위해 이중양분선택법 질문양식을 이용하여 긴급통보시스템에 대한 이용자들의 지불의사액(Willingness to Pay : WTP) 추정방안을 제시하였다. 기존 연구들의 경우 지불의사액 산정에 사용되는 질문 유형별 분석 모델별로 지불유무에 따른 절단데이터가 다르게 처리되고 있음을 알 수 있었다. 이에 따라 본 연구에서는 이중양분 선택법으로 구성된 절단 데이터를 처리하는 방법으로 모형별 지불의사액의 차이를 비교하였다. 연구에 사용된 설문지는 약 500부 수준으로 응답자의 지역적인 편차(bias)가 반영되지 않도록 온라인과 오프라인에서 동시에 진행하였으며, 연령대별 편차를 고려하기 위해 2010년 인구주택 총 조사 결과를 참조하여 자료를 구성하였다. 최종적으로 더 나은 자료의 해석을 위해 생존분석, 다중회귀분석, 토빗분석 등 다양한 통계기법을 적용하여 결론을 도출하였다.

The purpose of this study is to estimate conservation value of fisheries resource protected area by the double-bounded dichotomous choice contingent valuation method. The data in this analysis come from a survey of respondents of resident in fisheries resource protected area using a proportional stratified sampling from the population. The questionnaires covered all the 5 fisheries resource protected area and the sample size of every protected area was 120 questionnaires. The survey period was from August to October in 2016. Above all, the average willingness to pay amount(WTP) per person of Namhae-Tongyoung I, Namhae-Tongyoung II, Jindong bay, Hansan bay, Cheonsu bay is estimated \6,215, \13,215, \6,405, \9,785, and \10,390 respectively. And, the total value of Namhae-Tongyoung I, Namhae-Tongyoung II, Jindong bay, Hansan bay, and Cheonsu bay is evaluated \108.8 billion, \357 billion, \118 billion, 210.2 billion, \ 245.8 billion respectively. Moreover, the yearly value of Namhae-Tongyoung I, Namhae-Tongyoung II, Jindong bay, Hansan bay, and Cheonsu bay is evaluated \6 billion, \19.6 billion, \6.5 billion, 11.6 billion, \ 13.5 billion. In conclusion, fisheries resource protected area has the higher conservational value. Consequently, it is essential for now or future generation's use of fisheries resources. In light of the fisheries resource protected area's value and importance, this should be promoted to the public including the local community who utilizes fisheries resource protected area wisely. Also, this suggests that the policy for fishery resource's creation and management is needed in fisheries resource protected area.
