In a long-run, a price reduction of shine muscat that is one type of grapes is expected due to an increase of cultivated area. To come up with this problem, expanding exports of shine muscat considering that domestic demand is restricted in Korea. This study investigates the China consumers preference for shine muscat from Korea since exports to China have increased a lot after the quarantine agreement in 2015. Specifically, this paper analyzes a probability of shine muscat exports to China based on willingness to pay (WTP). Moreover, we derive long-run and short-run export strategies for Korean shine muscat. Our results show that a probability of exports to China is high. However, this probability is lowered at the sample of consumers who have the experience of tasted shine muscat. Considering the relative important characteristic for buying shine muscat at the sample of eating experienced consumers in China is sweetness, there is a need to develop cultivation technologies for enhancing sweetness to attain a sustainable development in the grape sector of Korea.

This study evaluated economic value recognized by the residents for the pleasant urban park management using contingent valuation method(CVM) to APEC Memorial Park in Pusan in terms of private fund development for the management of the city park. As a result, the estimated amount payable by each household for the management of APEC Memorial Park in Busan was between 5,673 won and 8,358 won. If such amount is expanded to households in park hosting area, it was 2.2~2.3 times of the park management budget in 2012, which demonstrates the willingness to pay (WTP) of residents for pleasant park was higher than the management budget. Social factors of respondents affecting WTP for city park management operation included age, educational level and income level. Those with high age and high education level had higher WTP. And, WTP was much affected by the use of park and recognition of residents. In particular, those with high frequency in the use of parks had higher WTP, and the users with more than once per week had 1.1 times higher WTP than overall WTP. Then, the satisfaction of park rather than recognition of necessity of park had led to higher WTP. Accordingly, it is necessary to manage park facility management and use program operation to enhance park satisfaction and it is also required to develop a park culture distribution policy to link such recognition to donation.

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.

This study analyzes the economic effect of rehabilitation and upgrading of reservoirs as a prevented method against natural disasters under recent abnormal weather conditions and dam-break. For the analysis, we divide the purpose of rehabilitation and upgrading of reservoirs into the stable supply of rural water under uncertain weather conditions and the prevention of collapse due to the aging of the reservoir. We measure the economic effect of rehabilitation and upgrading of reservoirs by estimating the resident's willingness-to-pay for the project through Contingent Valuation Method(CVM). The result shows that distributions of willingness-to-pay to prevent natural disasters and dam-break are similar to each other. About 66% of the residents in sample regions are willing to pay for the project. The resident's willingness-to-pay to protect natural disasters and dam-break are 32,250 to 46,147 won and 28,427 to 47,308 won respectively on average for all sample regions. The comparison of willingness-to-pay by type of regions shows that paddy field areas are the highest followed by facility cultivation areas and urban areas. In addition, total expected value of the projects calculated based on the resident's willingness-to-pay for paddy field areas and facility cultivation areas are much larger than actual project costs. This implies that rural residents are fully aware of the importance of the project to prevent natural disasters and dam-break and are willing to pay for additional costs if needed.

Proposing a method for the estimation of the social cost for global warming impact (external cost) is the aim of this paper. Both the endpoint approach and conjoint analysis were applied to estimating the social cost for global warming. The endpoint approach was used to assess the damage on the safeguard subjects by global warming due to the emission of greenhouse gases into the atmosphere. The conjoint analysis was used to estimate the economic values for safeguard subjects which measure the social preferences and willingness to pay (WTP) on safeguard subjects. The economic values of human health and social asset were estimated at 62,261,700 Won / DALY (yr) and 10,000 Won / 10,000 Won, respectively. Moreover, cost factors of GHGs were calculated by multiplying the damage factor which is quantified the unit damage on safeguard subject and the economic value. In the case of CO$_2$, the cost factor was calculated at 13.52 Won / kg (13,520 Won / ton). External cost of products or services can be calculated by multiplying the GHG inventory result of products or services by the cost factor of each GHG. inventory.

In the coming ubiquitous society, the importance of developing advanced public transportation systems (APTS) corresponding to individuals' needs and useful in their daily life is profound. In these regards, the study proposed new APTS services: Free internet access service and On-board real time traffic information service in public modes. A stated preference (SP) survey was performed to investigate individual's preference and willingness-to-pay (WTP) for the proposed APTS services. Multinomial logit models (MNL) incorporating the heterogeneity of respondents were developed to analyze individuals' preference and the difference of WTP. Some results of the study showed that the respondents' preferences were significantly different by in-vehicle travel times (30 min, 60 min) and their socioeconomic background. More respondents prefer new APTS services when invehicle travel time takes longer. For the housewife and self-employed group, the mean WTP for on-board realtime traffic information was higher than that of free internet access services, while for the company employees and students group, the mean WTP was similar in both services.

Korea has become the highest nitrogen balance (228 kg/ha) among 34 OECD member countries, and has the stigma of being a 'Nutrient overload country' as of 2019. Accordingly, research on the derivation and utilization of nutrient balance indicators and the 'regional nutrient management system' are being promoted to improve Korea's nutrient balance. It is necessary to support these policies and studies, form a public consensus on improving the nutrient balance, and evaluate the function of the public benefit. This paper aims to estimate the public benefit value of improving the nutrient balance based on an analysis of consumers' willingness to pay and recognition of Korea's nutrient excess for 600 consumers nationwide. As results, 21.2% of the respondents said they were aware of excessive nutrients in Korea, and 76.7% of the respondents said they were aware of the need for nutrient management. The average amount of intention to pay for the improvement of three pollution (soil, water quality, and air) that can occur due to a nutrient overload was ￦2,321.1 for soil pollution improvement, ￦2,391.2 for water pollution improvement, and ￦2,377.9 for air pollution improvement. The average willingness to pay for the three pollution reduction was ￦6,002.3. These results are expected to be used to form a public consensus on the balance of payments and to establish measures to enhance public interest values in the future.

In an aging society, as the number of people with disabilities increases concerns are raised about the quality of life of these people and their access to a safe environment becomes important. The purpose of this study is to find out the value of accessibility as an attribute of housing. To estimate the value of accessible, barrier-free housing, this study uses the Contingent Valuation Method (CVM) and analyzes the factors which affect the Willingness To Pay (WTP) of survey respondents by using Survival Analysis. In addition, the importance and satisfaction of barrier-free facilities in the dwellings of survey respondents was investigated. Since aging could be an important factor in influencing the need for accessibility, this study surveyed two age groups, one group (212 respondents) of people below the age of 65 and the other (162 respondents) of people above 65. The results of this study show that respondents would pay on average 2.67% more for being barrier-free when answering an open-ended question and 3.87% more for barrier-free housing when using the double referendum model. This is the increase in value that the respondents perceive as a consequence of removing all the architectural barriers from a dwelling. On average, elderly respondents would pay 2.99% of housing price for accessible features compared to 4.40% of the younger group. However, if the elderly who have willingness to pay for accessibility, the value the older group put on barrier-free housing was higher than the value perceived by the younger group. Factors that influence the WTP are importance of barrier-free facilities, education level and housing type. The value of dwellings without barriers estimated in this study shows the potential size and value of this kind of housing market to the housing development sector.
