  • This study strengthens importance of farm land has possessed rurality. Thus the amenities of farm village were offered to the symbolical attributes of rurality and it was extracted four amenities attributes for valuing the amenities. Possessing the importance of rurality for agricultural and rural development and rural tourism evaluated each attribute by Choice Experiment(CE) for sustainable development make full use of rurality. Applying for Conditional-Logit model estimated the value of attributes then consumer's benefit feeling form each attributes was offered to the value of a unit change. Through this study, I wish to apply for the direction of rural development as important material and the compensation in the operation of agricultural output offering social benefit as political reference materials.

  • This article estimates the economic values of changes in water quality of the Paldang Watershed by using the Choice Experiment (CE). The conditional logit model estimation results show that a small improvement in water quality from the 'status quo' level to the level of 'very good' increases average household's monthly utility by 3,157 Won, whereas a water quality degradation down to the 'normal' level gives rise to an increase in the monthly average utility by 9,649 Won. The corresponding social gain and loss of water quality changes to the Metropolitan Area were thus estimated about 285 billion Won and 872 billion Won, respectively. This article seems meaningful in that it resorts to the new water ecosystem classification criteria and indices that are respondent-friendly. They help a CE study like this to overcome one of its critical weakness that the number and contents of attributes of a CE study can quickly add to the information overload problem, especially where the environmental good under investigation is hard for ordinary respondents to understand.

  • This study applied the choice experiment (CE) method to measure values of statistical lives from multi-attributed mortality risk reduction choices. The four characteristics of mortality risk (i.e. cause of death, voluntariness of mortality risk, timing of death, magnitude of mortality risk reduction) are utilized to design the alternatives of choice sets. The estimation results for the multinomial logit model show that individuals are willing to pay 27,930 won per year for a change from the status quo to a $\frac{1}{100}$ mortality risk reduction for 10 years, 116,773 won per year for mortality risk reduction associated with adults, 97,682 won per year for voluntary mortality risk reduction, 77,234 won per year for involuntary mortality risk reduction. There were several estimates of VSL related to different attributes of mortality risk. The mean VSLs of infant/child/young adult ranged from 1,165 million won to 1,367 million won. The mean VSLs ranged from 1,631 million won to 1,833 million won for adult, and were between 1,128 million won and 1,330 million won for old person.

  • The Korean government is considering the implementation of a project to develop a deep-sea human-operated vehicle (HOV) to improve the level of deep-sea research. Information on the scientific benefits from the project is urgently needed in order to come to a decision about whether to implement the project. This paper measures the conservation value of developing nine attributes associated with HOV by using the choice experiment (CE). A survey of about 356 experts was undertaken and 132 experts completely responded to the survey. To deal with the CE data from the survey, we employed a multinomial logit model. All the coefficient estimates are statistically significant and consistent with prior expectations. Therefore, we can judge that the respondents' works required in the CE survey were within their cognitive abilities and they reported responsible and significant values. Each marginal willingness to pay for each attribute associated with the HOV is statistically significant and provides good information on the scientific values with regard to developing the HOV. The results can be utilized in evaluating and planning several alternatives related to developing the HOV.

  • Recently, there have been a lot of studies for the value for wetlands with increased interest about wetlands. However, the value assessment for wetlands was usually conducted for 송 natural wetlands only, without consideration for Dam-wetlands. In this study, we assumed that a dam carried out a function of wetlands and defined such dams as Dam-wetlands. Choice Experiment(CE) was used in value assessment method. Study area of this study is Boryeong-dam. We performed questionnaire survey in six metropolitan cities and Boryeong city for the value assessment of Dam-wetland. The result of questionnaire survey was analyzed using a Conditional Logit(CL) and a Random Parameter Logic(RPL). Therefore, the total values of a Boryeong-dam is estimated as 72.8 billion-won when consider the wetlands of surrounding area.

  • One of the most important factors that determine the quality of a stated preference study is questionnaire design. This study introduces strategies for enhancing the rationality and testing for the validity of choice experiments(CE) using "example" choice questions that mimic the main choice questions. From the case study of WTP for reduced radon radiation exposures in the home, the study found that screening out irrational responses, 12% of the effective responses, resulted in a meaningful increase in model fit. Meanwhile the study tested for anchoring effects, as a way of confirming the divergent validity of the study, by looking at equality of models estimated for two subsamples. The overall test results were mixed. The pros and cons of the questionnaire design strategy employed are also reported.

  • The coast of Incheon reaches Incheon itself, Gimpo, Siheung, and Ansan of Gyunggi-do. Because this area has been seriously polluted, the Ministry of Oceans and Fisheries has established the Incheon Special Area Management Plan (SAMP) to preserve sea water quality as a marine environment asset. However, there is concern that actions taken in this area may change the surrounding marine ecology, being effected by farms, via a river that flows from waste lands, abandoned fishing activities and fishing nets, etc. Given this background, this study estimates the value of SAMP sea water quality using a choice experiment (CE). A CE survey of 1,000 households was undertaken, investigating trade-offs involving price and four attributes for selecting a preferred alternative to obtain a marginal willingness to pay (MWTP) estimate for each attribute. The estimation results showed that MWTP for a 1 %p improvement in sea water quality, the diversity of fauna species, the diversity of flora species, and a 1 %p reduction in marine litter as a result of conserving Incheon coastal sea water quality are estimated to be KRW 75, 135, 309 and 72 per household per year, respectively. All estimation results were statistically significant at the 1 % level. These findings can provide policy makers with useful information for evaluating and planning marine environmental management policies.

  • The purpose of this study is to survey on parents' preference and estimate parents' Willingness to pay(WTP) for after-school rural experience program in daegu city by choice experiment(CE). The results of this study are as follows; First, we divided after-school rural experience program into three types, namely: nature seeing, play exercise and learning experience. Second, the study has shown that parents prefer learning experience among those after-school rural experience programs. Among attributes which form a experience program, instructor certificates, consuming time and expense for participant are statistically effecting significant impact. Third, the result of estimation on willingness to pay for development of after-school rural experience program is as follow. The willingness to pay for learning experience is 6,337won, willingness to pay for instructor certificates is 14,102won and it for consuming time is 2,926won. Therefore, composition centering learning experience is better and instructor who has expert certificate is required. It is much better to compose that the consuming time is longer and the expense for experience is lower. But there is limitation because this survey was conducted based on an assumption, so it could read over estimation problem. The result of this study may provide useful information to develop after-school rural experience program using rural resources and to improve rural tourism policy.
