The purpose of this study is to evaluate the benefits of flood control reservoir and to derive the policy implication by significant variables of willingness to pay. As a result of analyzed using contingent valuation method, variables that affect the amount of willingness to pay are housing area, frequency of disasters, educational background, and family income. All variables are analyzed as the plus effect for the willingness to pay, and the annual benefits of flood control reservoir per family are estimated as approximately 32,000 won. The implication of this study is as followed. First, the value of the respondents about public goods is not small. Second, the contingent valuation method can be useful plan to estimate the value of public goods. Finally, the benefits should be compared with various aspects because of the wide deviation of the demand population.

The word is endeavoring to reduce greenhouse gases with the sense of crisis caused by the continuous climate change. As a method to decrease greenhouse gases, motors driven by fossil fuels are being substituted by EV in the field of transportation. Meanwhile, for the spread of EV, charging installations are divided into general charging type and quick charging type. Also, charging amount and time are main factors to decide charging pay. But, because the opportunity coast for the charging time varies depending on the private situations, it is very important to understand exact phenomenon for the spread of EV charging installations and charging pay policy. Therefore this paper suggested the choice model of charging installation and time value in various situations by using Logit model to make clear the relationship between a choice of charging installation, charging time and willingness to pay for charge.

This paper is concerned with the assessment of benefits from water quality improvements. The contingent valuation method (CVM) is employed to directly measure the value of the project for the improvement of the water pollution in the Kumgang area. The perceived value of the improved water quality is investigated by using questionnaires to those concerned living near water-polluted area. The questionnaire includes such questions as the amount to willingly pay, the motivation to pay, the reasons of rejecting the payment, and some socio-economic data. The results of the survey show that (1) non-use value of the environmental goods is perceived to be more important than use-value of the environmental goods; (2) "willingness to pay" for the improved water quality varies according to the degree of educational level. income level and ages; (3) the resistance to pay for the project comes from the "polluter's pay principle".

Objectives : The purpose of this study was to estimate the willingness to quit cigarette price among Korean male adults, and to examine the factors affecting the willingness to quit cigarette price. Methods : The data was collected by a random digit dial telephone survey. 702 samples were analyzed by using t-tests, ANOVA and OLS regression analysis. To estimate the willingness to quit cigarette price, smokers were asked dichotomous questions with open-ended follow-up and the starting point of the price was randomized by one of 5 bid prices elicited from a pilot study. Results : The mean of the willingness to quit cigarette price was 4,287 Won per package, which was about 2,000 Won higher than the mean of the actual price the smokers now paid. About 41% of respondents were willing to quit smoking if the price of cigarette would be increased by 3,000 Won, and if the price would be increased by 20,000 Won, all respondents were willing to quit smoking. The factors associated with the willingness to quit cigarette price were the place of residence, the amount of smoking and the degree of exposure to smoking through the mass media. Conclusions : The results showed that to get people to quit smoking, increasing the cigarette price would obviously be effective and much higher prices have a greater effect. Furthermore, to enlarge the effect of increased cigarette prices, providing more cessation programs to small towns, reducing the amount of smoking and decreasing or prohibiting advertisements of cigarettes and smoking in the mass media will be efficient.

According to rapid increase of the population of senior citizens, there has been growing concern of Long-Tenn Care(LTC) services recently. Long-Tenn Care services, however, haven't been established systematically in Korea and the supply of LTC services is not sufficient despite the increase in the current social demand. This study aims to estimate the 'Willingness to Pay(WTP)' for LTC insurance which the government plans to introduce by means of social insurance, using Contingent Valuation Method(CYM). In addition, this study analyzes the factors affecting WTP for LTC insurance. An interview survey was carried out to derive WTP for LTC from 450 people who lived in Seoul aged 20 and above during the period from 16th to 21st of June 2003. Double-Bounded Dichotomous Choice Method was applied among several CVMs available to estimate both use value and no-use value of goods. There was pilot survey carried out prior to the main survey. The results show that the average monthly. WTP for LTC provided in home and residential setting is 18,192Won and 19,293Won, respectively. In the case of home care, WTP goes higher depending on reliability of LTC insurance policy and need for LTC insurance, as well as marital status, education and average monthly income. On the contrary, WTP is conversely affected by higher age and higher bids. In the case of institutional care, the factors affecting WTP are similar to those of home care, except age. This study followed NOAA's suggestions generally and the value derived through survey could be reliable. However, there can be the least bias in the process of survey because the CVM should be used under the supposed circumstances. Despite those limitations, it can be concluded that the amount the citizens are willing to pay for LTC is high enough to meet the costs needed to provide LTC.

This paper attempts to examine households' willingness to pay (WTP) for ground water pollution improvement which can be used in cost-benefit analysis on the project for developing the soil pollution control technique. We applied a contingent valuation (CV) method to obtain at least a preliminary evaluation of the WTP. The CV survey was rigorously designed to comply with the guidelines for best-practiced CV studies. We surveyed a randomly selected sample of 500 households in Seoul metropolitan area and asked respondents questions in person-to-person interviews about how they would be willing to pay for the program. Respondents overall accepted the contingent market and were willing to contribute a significant amount (1,195 to 1,552 won), on average, per household per year. The aggregate value of the project for developing the soil pollution control technique amounts to approximately 20.3 billion won per year. The household values can be the benefits that ensue from the project and compared with the costs of the program to determine whether the project is economically desirable.

This study aims to determine the value of the willingness to pay(WTP) admission fees through surveying the level at which visitors to national science museums in Korea are willing to pay for admission fees. The determination helps objectively identify ways to substantially increase admission-based revenues, thereby enhancing managerial efficiency of national science museums. Using the contingent valuation method(CVM), we analyzed the WTP for admission fees of 250 visitors to Gwacheon National Science Museum. The statistical analysis revealed that the average amount of WTP was far higher than the current admission fees(4,000 won for adults and 2,000 won for children and adolescents). WTP of questionnaire respondents was normally distributed at the mean of 8,447 won for adult admission and 6,535 won for non-adult admission to Gwacheon National Science Museum. This result can be used as basic evidence to redetermine admission fees of national science museums and ultimately improve financial vitality.

Background: The purpose of this study is to emphasize the importance and necessity of the government's old-age preparation service by measuring the economic value of the old-age service and the policy direction and policy implications of the government's old-age preparation service project. Methods: Contingent Valuation Method (CVM) was used as an analytical method. CV methodology was used to calculate the Willingness to pay (WTP) for old-age preparation service and its value was estimated and the economic benefit of the project was estimated. Results: As a result of the analysis, the average monthly payment amount for the old service was calculated as 5,100 won, and the annual average payment amount was estimated to be 61,197.1 won. Conclusion: The present value of the benefit for 10 years with the discount rate of 5.5% is 484,651 won. Based on the value of peruser benefit, the total benefit value calculation result of the old-age preparation service considering the Willingness to pay for the next 10 years shows that the total benefit value of the old service, which occurs during the period from 2016 to 2025(10 years) was estimated at 415.1 billion won. As a result of calculating the benefit for each scenario, the present value of basic service is higher in all scenarios than the linked service.

In this research, photo images of uncultivated marginal lands were simulated to visualize alternative land use patterns using image capture technology. Based on an original photos, 3 simulated images were created ; barren condition, aforested condition and shrub-covered condition. The simulated images were then used to evaluate respondents' visual preference(SBE value) and willingness to pay for the agricultural development tax as a hypothetical payment vehicle. The SBE values for barren condition are the lowest, as expected. When original condition is changed to forested or shrubbed, the SBE values are increased significantly. The logistic models for the willingness to pay for the various alternative land uses performed significantly, ${\rho}$ statistics for 6 models ranges from 0.3 to 0.4 and correct percentage for predicted probability are about 75%. Among independent variables, the amount of tax offered is the most influencing factor to predict the probability. Income also shows some relationship with no statistical significance. Other variables behave inconsistently in the model. When SBE and WTP are correlated, rather consistent trends can be observed. With the increase of SBE, WTP predicted by the model increases accordingly. It can be concluded that enhancement of scenic quality of the agricultural lands leads to increase of people's willingness to pay to support the rural environmental conservation.

This study attempts to estimate the benefits of environmentally-enhancing water ensuing from Sangkwan multi-purpose reservoir. To this end, we apply a survey technique, the contingent valuation (CV) method to elicit the public willingness to pay (WTP). Two CV surveys of randomly selected households were administrated to on-site and off-site areas. As it happens, a number of respondents reported zero WTPs for the environmentally- enhancing water. To deal with the zero WTPs, this study employs a spike model. The results show that average household's WTP for the environmentally-enhancing water ensuing from Sangkwan multi-purpose reservoir is estimated to be 1,393.7 won for on-site area and 2,237.7 won for off-site area per year. The benefits of environmentally-enhancing water ensuing from Sangkwan multi-purpose reservoir amount to about 38.3 billion won per year. Our findings are expected to contribute to determining an appropriate level of investment and making management policies with regard to the benefits of environmentally-enhancing water.
