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.

The generally known important functions of forests include air purification and the health benefits that humans can receive when relaxing and enjoying recreation in the forests. In recent years, people have appreciated the value of the natural environment but it is not easy to answer the question how much monetary value a natural environment has. Because environmental property is public property, which is not traded on the market, market prices cannot be established, so it is not easy to assess the currency value. Methods for estimating environmental property value have been studied by economists. The representative method for measuring environmental property value is a contingent valuation method, or CVM. Various methods have been researched and attempted along with the development and fusion of mathematics, statistics, and economics. Representative methods of CVM are single-bound and double-bound logit and probit methods. This study has been carried out to compare four estimates. Estimates are as follows: the lowest estimate is derived from a single-bound logit WTPmedian while the highest estimate is from double-bound probit WTPmean. While there are some preceding studies on price estimation and methods of measurement through CVM, they offer only partial comparisons. This study suggests four analytic methods and prices through 1,123 questionnaires. The results can be used for the subsequent comparison of estimate prices and the methods of measurement

The purpose of this paper is to estimate 'willingness to pay' for mobile data service by using contingent valuation method with double bounded dichotomous choice question. The findings are as follows.: First, the willingness to pay of mobile data service is considerably lower than current retail price. Second, the perceived degree of mobile data service such as awareness and benefit recognition is positively related to the willingness to pay of mobile data service. Our results suggest that active promotion and strengthening of the content of mobile data service are needed in order to enhance the profitability of mobile operators. The analysis results will be used to set the mobile operator's pricing strategy and to build up a successful communication policies in the mobile ecosystem.

Recreational forests are catching on as places for personal development through recreation, association with people, education about nature, mind relaxation and spiritual peace. However, the value and significance of recreational forests with various functions are easily overlooked. Whoever pays fees for admission to facilities are able to enjoy fresh air, a comfortable environment, and space for rest. It should be taken into consideration whether the fee which customers pay is appropriate for the value of nature they are enjoying. This study is involved in giving the right recognition to the value of recreation and environment by estimating economically the value of the environment in which visitors stay, and presenting the appropriate price. The most efficient way to achieve this goal is through an economic approach, which suggests following established research skills and yielding suitable and accurate amounts of money. The environmental value of a recreational forests is estimated through contingent valuation method(CVM), which is chosen among several methods to estimate public facilities because the value of recreational forests has strong characteristics as public facilities which are not traded in the market. The annual recreation value per person of surveyed recreational forests is Willingness To Pay(WTP) with a mean between about 16,000 won and 25,400 won. The recreation value of one recreational forest surveyed is annually between approximately 1.7 billions won and 2.7 billions won. The annual recreation value of 85 national and public recreational forests is presumed to be between about 140 billions won and 230 billions won. The presumed amount of money is the environment in which visitors can enjoy whenever they invest some money and time. Indeed, it is more than that; it provides visitors with a greater sense of satisfaction and the recognition of the preciousness of nature and the environment.

In this study, the economic value and economic ripple effect of the Jeju Inland Port redevelopment project were estimated. The economic value was estimated from the viewpoint of amenity, the value of non-market goods such as landscape improvement, environmental improvement, and recreation effects. As a result of the estimation, the population was divided into Jeju Island and other regions and the individual's willingness to pay was estimated to be 2,952.9 won in Jeju Island and 4,722.8 won in other regions. On the other hand, the economic ripple effect of the Jeju Inland Port redevelopment project was estimated during the project period and after the completion of the economic ripple effect was estimated. As a result of the estimation, the production inducement value was KRW 84,387 million, the value-added inducement effect was KRW 37,292 million, and the employment inducement value was 5,846 employment when the (direct employment + indirect employment) effect was combined. After the end of the project period, as of 2022, there were 518,000 foreign tourists, and the value-added inducing effect was estimated to be about 149,885 million won.

The government recently implemented policies to improve transportation for the disabled passengers. On the other hand, metropolitan public transport still lacks adequate services for these individuals. Many new cities lack urban rail lines and focus on high-floor buses for expansion. Wheelchair users can only access to double-decker low-floor seat express buses for intercity travel. This study examined the necessity and rationale for introducing low-floor seat buses by estimating the user's willingness to pay through a contingent valuation method. Two methods for eliciting the willingness to pay were adopted: open-ended and dichotomous choice questions. The binomial logit model was used to estimate the willingness to pay. The results indicated that the general public is willing to pay an additional 126.7 Korean won, while the disabled passengers are willing to pay an additional 117.5 Korean won. When translated into annual economic benefits, this amounts to approximately 35 billion Korean won.

This study is intended to check economic value of and factors influencing children's library. To this end, data on a total of 614 questionnaires to which parents among users of 6 children's libraries responded were collected. The results of analysis by contingent valuation method after selecting library fee per person as payment vehicle were as follows. First, willingness to pay was estimated to be a monthly average of KRW 9,243 per person. Second, it was shown that factors influencing willingness to pay included the frequency of utilization, satisfaction, the number of children per family, gender, age, and income and so on. Third, with regard to influence according to each factor, an additional unit in all the rest of factors except gender increased probability of willingness to pay such as the frequency of utilization(1.140), satisfaction(1.335), the number of children per family(1.417), age(1.124), income(2.426). On the other hand, in terms of gender, probability of willingness to pay was lower in female by 0.364 than in male. The implication of this study is that an interview is held with actual user and specific amount of money is presented regarding the economic value of children's library, which has been little known until now.

This study estimates the willingness-to-pay(WTP) for conserving Sindu coastal sand dune and asset value of Sindu coastal sand dune by means of contingent valuation method. CV market scenario is designed to elicitate his/her WTP considering use value and nonuse value of Sindu coastal sand dune. The yearly WTP for Sindu coastal sand dune is 3,059 won(95% C.I. 2,591~3,612 won) in the case of a househodl, therefore amounts to 44 billion won(95% C.I. 37~52 billion won) for the whole nation. We estimate the asset value of Sindu coastal sand dune by 7.5% discount rate to be 587 billion won with 95% confidence interval of 497 to 693 billion won. The direct use value which has accounted for 13.4% is 79 billion won(95% C.I. 67~93 billion won), and the indirect use value which has accounted for 30.2% amounts to 177 billion won(95% C.I. 150~209 billion won), and the option value which has accounted for 19.4% is 114 billion won(95% C.I. 97~135 billion won), and the conservation value which has accounted for 37.0% amounts to 217 billion won(95% C.I. 184~256 billion won).

An arboretum is defined as a collection of facilities that conserve plant species by surveying, collecting, and proliferating and preserving the plants in nature, perform diverse researches on plants and display the plants in exhibition spaces or outdoors as well as provide the public with educational programs and refreshment spaces according to the laws concerned. The public, however, recognizes the exhibition and education functions on plants of arboretum more importantly compared with the roles to survey, collect, and proliferate plants as regulated by the laws. In particular, arboretum plays a role to offer a pivotal educational place in urban area where the public can obtain an hands-on experience and understanding on a wide range of plant species and natural environment. The study aims to estimate the non market environmental values of Daegu Arboretum operated by Daegu Metropolitan City government by using the Contingent Valuation Methods (CVM), which yields the current monetary estimates for the arboretum. The value estimation was undertaken by using the Double-Bound Dichotomous Choice (DBDC) method, and each estimated value was derived from respective functions based on a logit distribution known to include relatively stable estimates according to the shape of the distribution. Considering the statistical fitness test results, the author estimated the amounts of the Willingness To Pay (WTP) such as mean WTP of 12,718 KRW, median WTP of 11,033 KRW, and truncated mean WTP of 11,468 KRW, which represented the annual recreational values per a person visiting Daegu Arboretum respectively. The analysis showed that Daegu Arboretum created the annual environmental values which were estimated to be approximately 16 to 19 billion KRW. The study also has an implication that the valuation method for the environment of Daegu Arboretum may be effectively applied for estimating the values of other types of environmental goods by altering the locations or goods to be analyzed.
