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.

In Korea, a proton linear accelerator complex is being built as a part of the 21st Century Frontier Projects. Contingent valuation method (CVM) is a main evaluation method of nonmarket goods for which markets either do not exist at all or do exist only incompletely. This study shows the method can be applied to the benefit assessment of the proton accelerator complex. Using the discrete choice CVM method, this study estimates the willingness-to-pay (WTP) of a would-be user for the proton accelerator complex as 20,133 won per month.

DMB data broadcasting has recently come into the spotlight as a platform for a new business opportunity and an application of various contents. This paper estimates the willingness to pay for the DMB data broadcasting services and explains the demand characteristics for TPEG, BIFS and BWS services, using the Double-bounded dichotomous choice Contingent Valuation Method. Consumers are willing to pay 2,039 Korean won for TPEG service and 1,612 Korean won for BIFS and BWS services per month, which corresponds to the market size 87.6 billion Korean won for TPEG and 195.2 billion Korean won for BWS and BIFS a year respectively. It is also found that the more consumers show usage intentions, have experiences in the similar services, and know of the DMB data broadcasting services, the more they are likely to pay for the DMB data broadcasting services.

The purpose of this paper is to introduce and test an extension of dichotomous choice contingent valuation(DC-CV) methods of pre-test-market evaluation using the specific case of a cable telev-ision service. Specifically we used a double-bounded DC-CV approach. On the whole respondents accepted the contingent market and were willing to contribute a significant amount on average. This willingness varies according to individual characteristics and concerns about the service. It is concluded that the methods are potentially a useful tool for decision-makers in measuring the po-tential demand for a new cable television service and considering the provision of the service.

본 연구는 사용자 경험(UX)에 대한 경제적 가치 평가 모델을 탐색하고 적용하는 것을 목적으로 수행되었다. 스마트폰 잠금해제 UX를 대상으로 터치형, 지문인식, 홍채인식에 대해 조건부 가치측정법(contingent valuation method, CVM)을 적용하였다. 경제적 가치를 산출하기 위한 가치추정법 중에서 조건부 가치측정법을 선택한 이유는 잠금해제와 같은 인터페이스 요소들은 스마트폰을 이용할 때 중요한 사용자 경험적 가치이지만 시장에서 별개로 거래되지 않는 비 시장 재화이기 때문이다. 스마트폰 잠금해제를 조건부 가치측정법 중 이중 양분선택형 방식(double-bounded dichotomous choice)으로 설문조사하여 로짓 모형으로 분석한 결과 터치형 잠금해제 인터페이스는 529원, 지문인식 잠금해제는 4,214원, 홍채인식 잠금해제는 1,376원으로 경제적 가치가 나타났다. 즉, 지문인식 잠금해제가 가장 높은 경제적 가치를 나타냈으며, 그 다음으로 홍채인식, 터치형 순이었다. 이 연구의 주요 기여점은 UX 디자인에 대해 경제적 가치를 평가하는 방법론적 시도를 수행하였고, 체계적이고 신뢰도 있는 결과를 산출하였다는 점이다.

Contingent valuation method (CVM) is a main evaluation method of nonmarket goods for which markets either do not exist at all or do exist only incompletely; an example is environmental good. A dichotomous choice approach, the most popular type of CVM in environmental economics, employs binary discrete choice models as statistical estimation models. In this paper, we propose a semiparametric dichotomous choice CVM method using local linear model of Fan and Gijbels (1996) in which probability distribution of error term is specified parametrically but latent structural function is specified nonparametrically. The computation procedures of the proposed method are illustrated with a simple design of simulations.

The purpose of this study is to estimate the utility value of boat fishing experience marine tourism activity in Jeju Island's Chagwido. The utility value is estimated by single bounded and double-bounded dichotomous choice contingent valuation method. The contingent valuation method is used to estimate economic values for all kinds of coastal ecosystem services. The method involves directly asking people, in a survey, how much they would be willing to pay for specific environmental services. So, the method has great flexibility, allowing valuation of a wider variety of non-market goods and services than is possible with any other non-market valuation technique. This study collects the effective 504 questionnaires from boat fishing experience tourists in Jeju Island's Chagwido. The results show that the average willingness to pay amount(WTP) is estimated to be about 17,000 Korea won by single bounded and double-bounded dichotomous choice contingent valuation method. This indicates that the utility value of boat fishing experience marine tourism activity is estimated to be about 17,000 Korea won in Jeju Island's Chagwido.

본 연구는 조건부가치측정법(CVM)의 지불의사유도 방법으로 가장 많이 적용되고 있는 양분선택형 응답자료를 활용하여 WTP 함수의 추정과 편익의 측정단계에 쟁점이 될 수 있는 경제이론적 근거, 확률분포의 가정, 확률모형의 표기, 함수형태 그리고 편익의 범위 등 분석자의 입장에서 중요한 제요소들에 대해 이론적으로 검토하고 산림보존을 위한 가치추정 자료를 사용하여 실증적으로 분석하였다. WTP 함수를 선형으로 표기하는 한, 확률효용모형과 확률지출모형은 쌍대적 접근으로 해석할 수 있었고, 또한 확률모형의 오차항의 분포를 정규분포로 하든지 로지스틱분포로 가정하든지 계수들의 추정치와 이들을 사용하여 측정된 표본 WTP도 차이가 없었다. 그러나 이중양분선택모형은 WTP 함수 추정과 편익측정 결과는 두 CV 제시금액에 대한 응답이 같은 WTP 분포로 왔다고 보기 어려워 단일양분선택형 모형이 갖는 유인일치성이 약화되었다. 나아가서 WTP를 비음의 영역으로 제한하는 WTP 함수형태의 경우 척도모수가 클 경우 표본 WTP의 평균과 중앙값이 크게 다른 것으로 나타났다.

This study intended to estimate the willingness-to-pay amount by farmers for the automatic guidance technology of Combine. Contingent Valuation Method was employed for this estimation using survey data from 65 Combine using farmers. Based on the dichotomous choice model, farmers’willingness-to-pay for the automatic guidance technology was ranged from ￦4,772,000(median) to ￦5,268,000(mean). The estimated willingness-to-pay by the for the new technology was approximately one quarter of the average value based on the willingness-to-pay for the new technology was approximately one quarter of the average value of Combine in sample farms. This implies that there is an economic rationals for developing the new technology as long as it will be available with the cost less than the amount of estimated willingness-to-pay.

The paper is to estimate willingness-to-pay (WTP) for tap water quality improvement in Busan, using parametric approach in contingent valuation method(CVM). For parametric approach linear logit model and log logit model are employed in double-bounded dichotomous choice format of CVM. For the reliability and the validity of contingent valuation method a survey was conducted for 665 respondents, who were sampled by stratified random sampling method, by personal interview method. The result of mean WTP for the tap water quality improvement in Busan was estimated to be 3,687 won and 3,660 won per month per household, while median WTP being 1,884 won and 1,892 won per month per household, respectively by linear logit model and log logit model. Provided that our sample is broadly representative of the Busan's population, an estimate of the annual aggregated benefit of residential water improvement for all Busan households is approximately 29.7 billion won to 29.8 billion won based on median WTP.
