  • Rural Development Administration (RDA) has developed a manufacturing technology which can increase the amount of platycodin D in Platycodon grandiflorum. A study is needed to estimate the value of this new technology and predict the market demand for a new product. This study estimates additional amount of willingness to pay (WTP) using contingent valuation method (CVM) for a new product with the technology that RDA has developed. The survey was created under virtual health functional foods market of Platycodon grandiflorums. It was conducted with 1,000 adult males and females aged between 19 and 59 years old in 17 major cities and provinces nationwide from December 4 to December 7, 2018. The amount of WTP for the health functional Platycodon grandiflorum was drawn using maxinum likelihood estimation method. The estimated average and median WTP values are 21,933.85 won per person and 10,000 won per person, respectively. The independent factors, including the ratio of monthly average health function food consumption to income, the average monthly income level of a household, and existence of family members or relatives engaged in food and nutrition-related professions in a household, have been shown to have a statistically significant influence on the WTP. This study presents the potential magnitude of health functional food market and the value of the new technology based on health functional food market.

  • This study aims at integrating economic tools and remote sensing for environmental impact valuation of the Isahaya Bay Wetland (IBW). In doing so, we have used potential behavioral economic valuation technique: contingent valuation method and satellite remote sensing technique: land cover mapping. From the results of the study, we are able to bracket a range of values from (22 to 200 billion yen) for arriving at the true economic value lost due to the initiation of reclamation project on the IBW and would provide a new dimension to get nearer to the more accurate environmental impact assessment.

  • 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.

  • Visual conservation center is a facility for the preservation of visual materials such as film and digital image data, and its construction project is currently being considered. This study evaluates the economic benefit of the project using CVM (Contingent Valuation Method), the main method of nonmarket evaluation in the both domestic and foreign literature. Survey data used in the analysis was collected in seven major metropolitan cities using person-to-person interviews and a logit model is used for the econometric estimation. The economic benefit measured by a household's average willing to pay (WTP) per year is shown to amount to 8,958 won.

  • Abandoned roads, abandoned expressways included, cause a lot of problems such as contamination and environmental damages to underground water, fragmentation of wildlife habitats yet they are not appropriately maintained or managed because of jurisdictional conflicts and, often more importantly, insufficient budget of governments. The restoration of abandoned roads is known to benefit society and its constituents by providing better environment and higher living standards but the monetary value of the benefit is hard to measure because of non-marketability of the good that the restoration brings about. In this case, the contingent valuation method(CVM) is most powerful in evaluating non-marketable value of goods and hence it is used widely. We also used the CVM to value the benefit of restoration of abandoned expressways to find out: about 40% of total households are willing to contribute positive amount for restoration; better awareness of environmental issues leads to higher willingness-to-pay.

  • This study aims to present a new approach to measure the economic value of the public libraries, identifying and suggesting the modified contingent valuation method (CVM) application. The modified CVM, which applied Dissonance Minimizing (DM) format, is presented as a new approach. A cost-benefit analysis is used as a tool to determine if the benefits of public libraries outweigh the cost incurred in providing the services. The benefits of public libraries are based on estimates of how much the user is willing to pay for the library services and costs are based on the prices of providing the services. A comparison between two methods are conducted in a case study in order to measure the economic value of 'J Public Library'. The study also conducts a case study to analyse the WTP value of the 'J Public Library' and demonstrates how public libraries approach the their local studies.

  • Recently, as there are a rise in the standard of living and higher concerns of an electromagnetic wave and environment, undergrounding the aerial cables which are supported by large pylons and generally considered as the least attractive feature of an urban area is on an increasing trend to improve aesthetic benefits and electric reliability. This study applied Contingent Valuation Method (CVM) which is expected to become an effective tool to measure indirect benefit to estimate the substantial benefits of undergrounding overhead power line projects in an urban area. The tunneling construction project of the 345kV Shinsungnam electric power cable in Seongnam city was selected and a hypothetical scenario was given to respondents to determine their levels of Willingness to Pay (WTP) for undergrounding overhead power lines. The result from the estimation of the WTP of undergrounding overhead power lines in Seongnam city was calculated as approximately 17.1 billion won. Placing existing overhead lines underground is difficult to justify economically. Most undergrounding costs appear to be justified by aesthetic and public policy considerations. Therefore, considering the result of this study, undergrounding overhead power lines is of great benefit to public.

  • Purpose: The purpose of this study was to evaluate the economic value of installing public Energy storage system (ESS) facilities using a logit regression analysis and Contingent Valuation Method (CVM). We focused mainly on the environmental benefits of ESS and analyzed how the users' attitude toward environmental protection and knowledge of renewable energy affect their Willingness to pay (WTP) Methods: A single-bounded dichotomous choice (SBDC) survey was used to collect the data. We asked participants whether they are willing to pay a randomly presented cost (KRW 100, 500, 1000, 1500, 2000, 2500, 5000, 10000) along with their attitude to toward environmental protection, knowledge of renewable energy, and perceived cost of electric bill. 417 valid samples were collected and used for the analysis. Results: The results of the logit regression show that the initial bid, attitude toward environmental protection, knowledge of renewable energy, and perceived cost of electric bill significantly affect the user's WTP of public ESS facilities. The CVM results show that users are willing to pay KRW 5,049.1/month to install ESS facilities. Conclusion: : According to results, we conclude that the users agree with the need to install ESSs and that environmental benefits of ESSs are important factors for ESS adoption. Therefore, policy makers need to emphasize environmental aspects to install the ESS facilities.

  • 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.
