As tourist are becoming increasingly environmentally conscious, government and related companies need to establish policies or strategies that encourage ecotourism. The aim of this study is to analyze individual preferences and estimate shadow prices, namely, willingness to pay for coastal wetland ecotourism. This study applies a contingent choice method to measuring marginal WTP for each attribute (tour duration, number of visitors, guide, program) of coastal wetland ecotourism. The finding herein contribute to complementing the valuation methods by estimating various attributes of coastal wetland ecotourism and providing policy-makers with useful methodological framework and quantitative information in the decision-making process related to ecotourism.

Many online content providers who use the Internet to distribute contents, such as news, music, games, books, and other types of information, have been experiencing an extremely competitive business environment. To survive in this environment, they have started charging a fee for the contents that they provide. However, there have been very few success stories in commercializing online contents. One of the biggest hurdles may be customers' psychological resistance against paying a fee for the contents that have been free of charge previously. Without examining customers' perceived prices for online contents, many online content providers have tended to decide their prices by themselves. Online games are not exceptional cases. Although many online game-related research works have focused on psychological and technical aspects, very few works have examined online garners' preference carefully. This study alms at exploring online garners' preference by measuring their WTP (willingness to pay) for online games.

The mobile telecommunication sector is increasingly gathering way becoming a key area for the economic development in Uzbekistan. One way to promote competition among providers is the introduction of a number portability service. This paper estimates subscriber's willingness to pay (WTP) for the MNP service in the mobile communication market in Uzbekistan. Consumer valuation was estimated using a conjoint analysis. Since number portability had not been introduced at the time of the study, stated preference data from the conjoint survey was used. Results indicate that currently subscribers do not attach a lot of importance to the MNP service, while price and service quality are most valuable components. The results of this study provide important implication for mobile network operators and policy developers on potential MNP implementation.

This paper reports the results of a study to elicit willingness to pay (WTP) for changes in health risks from exposure to As, Pb, THM in tap water using experimental market method. The experimental market method, compared with other non-market valuation methods, allows us to use incentive compatible demand revealing scheme, to acquire market-like experience through repetitive auctions, and to incorporate learning process by providing new information during the session. Participants seemed to utilize the objective risk information in a 'rational' manner, and to change their WTP bids accordingly. Moreover they were able to reduce the 'ambiguity' in risk perception processes when objective risk probabilities provided are quite different from their subjective perceptions. Nonetheless, anchoring effects appeared to be still persistent in spite of market-like experience and learning opportunity. And implicit values entailed by WTP bid/risk tradeoffs indicate a wide variation in values across alternative risk reductions and overrated responses to very small risk reductions.

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.

The purpose of this research is to valuate the economic value of the arboretum which will be provided in Multifunctional Administrative City by estimating citizens' willingness to pay with double-bounded dichotomous choice contingent valuation method, and to provide the basic information necessary for designing and managing it for the future by identifying the types of the variables affecting the WTP. It was found that respondent's average WTP for arboretum was \23,508, and when this figures applied to all the Seoul citizens aged between 20 and 59, the economic value of it was \157,000,000,000. The variables affecting the amount of WTP were visit intention, variety seeking tendency, level of income and environmental attitude. However, environmental attitude negatively affected the amount of WTP. Average WTP for the entrance fee was \5,090, and both variety seeking tendency and visit intention were influencing factor affecting the amount of WTP. Respondents were taking charging entrance fee for granted because most of arboretums are commercial. It can be expected that much of maintenance cost will be covered from the entrance fee.

The purpose of this paper is to analyze the difference of the value in main production areas affected through the hedonic price model and the conjoint analysis. In addition, the partial value of each attribute level, and the consumers' willingness to pay(WTP) for change in each attribute level are analyzed. For this, we compared the value of apple determined in Garak market with the value that consumers' WTP. The result showed that there is a gap between the market value and the consumers' preferences on apple. It means that it is necessary for the local branding to be more developed to receive higher sales. Furthermore, understanding the consumers' preferences on the apple attributes can enhance the consumer utility and the competitivity. As a result, this study provides an apple marketing direction for main production areas that has been changing due to climate change.

The main purpose of this study is to estimate willingness to pay (WTP) by the general publics, assuming that they pay tax or charge for protecting marine living resources and environment through developing and supplying biodegradable fishing nets. This study employed a contingent valuation method (CVM) which is an econometric method. The survey was conducted by using both double-bounded dichotomous choice and open-ended survey. Tobit model was used for the analysis. The variables included concerns about marine environment and fishing net discarded, sex, age profile, number of family members, educational level and personal disposable income. Annual average WTP per family for the biodegradable fishing net development and supply was estimated at 5,294 won and national WTP amounted to some 84.2 billion won. This includes both of use and non-use value of biodegradable fishing nets.

The purpose of this study is to estimate economic value of document delivery services(DDS) at foreign journal supporting center in K University library. For this study, Bass diffusion model, which is widely used in forecasting, especially new product and new service forecasting, was adopted. User survey was also carried out from September 10 to 20, 2007. As a result, useful value(UV) of DDS is estimated about not less than 2,000,000,000 won, and willingness to pay(WTP) is estimated about less than 2,000,000,000 won. This study, economic value analysis at foreign journal supporting center, was limited to DDS, and used methodology for the study is also limited to UV and WTP. Demographic analysis(i.e., sex, age, occupation, educational level) for UV and WTP is also conducted.

This paper is aimed to recognize trends of various social groups about multiple transportation policies such as the crosswalk restoration by eliminating the pedestrian overpasses and the improvement or continuous extension of existing pedestrian overpasses, currently implemented in Busan, following the globally prevailing pedestrian-oriented transportation environment. Also, this paper utilizes Contingent Valuation Method (CVM) to evaluate the efficiency of individual alternatives in terms of respondent's willingness-to-pay (WTP). Consequently, survey participants preferred the crosswalk or improvement of the pedestrian overpasses rather than depending on the existing pedestrian overpasses. In addition, the WTP value for the crosswalk restoration is approximately 42,452 won per household per year, and, on the other hand, the WTP value for the improvement of existing pedestrian overpasses is approximately 36,793 won per household per year, implicating that the transportation policy makers are suggested to place more priorities on crosswalk restoration than the improvement of the existing pedestrian overpasses.
