  • 본 논문은 정보재화로서 개인정보의 특징과 개인정보에 대한 경제적 고찰을 통해 개인정보 침해의 부정적 효과를 방지하기 위한 지불의사 비용, 즉 Willingness To Pay(WTP)를 분석하였다. 개인정보 보호를 위한 지불의사비용 결정요인에 대한 학술적 연구는 아직 미흡한 현실이다. 따라서 본 논문에서는 개인정보 보호를 위한 지불의사비용에 영향을 미치는 요인을 이중양분선택법(double-bounded dichotomous choice)에 근거하여 개인정보 침해를 예방하기 위한 비용을 결정하는 요인을 찾고자 하였다.

  • The purposes of this study are to estimate the economic value and reasonable entrance fee of the Yeido Park, which is under construction in Seoul, by conduct the face-to-face interview. A total of 645 daults were selected by two stage cluster sampling. The senario was designed to meet the requirements for doubgle-bounded dichotomous choice CVM, and distributed with the photograph to epict and compare the current and suggested conditions. A donation vehicle and entrance fee were utilized to find the possibility of strategic behaviors and protest zero, and to make the data estimatable tfor interval censored survival analysis. Date was calibrated by the survival analysis to eleminate the 'fat-tail problem'. Weibull distribution was assumed as a baseline distrubution. The mean WTP of donation and entrance fee was ₩5,281 and ₩783, respectively. The economic value of this park was determined by aggregating the mean value, giving a total WTP for the population of ₩36,861,645,000. This economic value was composed with the use value and existence value. The calibrationi of the Weibull proportional hazard model showed that nearness to the park, age, intention to isit the park, and educational attainment were significant independent variable to influence an amount of donation.

  • 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.

  • 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 연구에서는 도로투자 사업으로 인한 편익 중 일반적으로 계상하고 있는 통행시간 절감 및 차량운행비용 절감 등 직접적인 편익 이외에 추가적으로 이용자입장에서 체감할 수 있는 도로 주행 중 운전쾌적성 편익을 산정하고자 운전쾌적성의 정의를 마련하였고 운전쾌적성 산정방법론을 개발하였다. 도로특성(도시부/지방부) 및 차량 밀도(차간거리)에 따른 이용자의 지불용의액을 CVM 방법 중 가장 최근에 활발히 활용되고 있는 이중양분선택형(double-bounded dichotomous choice)질문법을 활용하여 설문조사한 후 그 결과를 로짓모형에 적용하여 운전쾌적성 가치를 도출하였다. 도시부 및 지역간 도로에서 공히 지불용의액의 크기는 전반적으로 기존 차간거리가 짧을수록 큰 것으로 분석되었고, 도로의 차간거리 변화가 같더라도 사업 전의 차간거리와 사업 후의 차간거리에 따라 지불용의액이 다른 것으로 나타났다. 즉, 도로의 차간거리가 증가하더라도 기존 차간거리가 어느 정도인지에 따라 지불용의액이 다르게 나타나 지불용의액이 기존 차간거리에 영향을 받는 것으로 분석되었다.

  • PURPOSES : Benefits for improvement of travel time reliability obtained from construction of new highways should be considered as a major factor in the feasibility study for highway constructions. The purpose of this study is to develop a method of estimation for the value of travel time reliability. METHODS : Highway type (urban/rural highway) and traffic flow type(interrupted/uninterrupted) was considered to estimate he value of travel time reliability. And Double-bounded Dichotomous Choice among Contingent Valuation Method(CVM) was applied to survey the willingness-to-pay of drivers when travel time reliability is improved. Finally the value of travel time reliability was estimated using the results of survey and logit model. The value of travel time reliability was estimated considering travel objectives, time constraint travel and non-time constraint travel. RESULTS: The value of travel time reliability of business trip is higher than that of non-business trip. The value of travel time reliability of time constraint travel is higher than that of non-time constraint travel. The value of travel time reliability in urban area is higher than that in rural area. CONCLUSIONS: It was concluded that the proposed method in this study is more realistic and proper to estimate the value of travel time reliability because it reflects the situations of time constraint travel and non-time constraint travel.

  • In Korea, the industry and marketing of livestock has grown because of increases in consumers' income and changes in food consumption trends. Livestock production and consumption increased tenfold from 1970 to 2018, and this rise will continue. However, the quality of marketing information for Korean livestock has remained low. The Korea Institute for Animal Products Quality Evaluation (KAPE) operates programs that provide marketing information on livestock, but the social benefits of these programs have not been objectively evaluated. The purpose of this study was to estimate the social benefit of the programs offering marketing information on Korean livestock. Survey and analysis using an economic model (double-bounded dichotomous choice contingent valuation model), revealed a few findings. First, the users of the marketing information programs offered by KAPE recognized the value of these programs and demonstrated their willingness to pay for this marketing information. Second, the social values of the programs offering marketing information on livestock were estimated as 1.1 billion won (marketing information on main livestock) or 5.3 billion won (price information on poultry), and these social values were 2 or 6 times greater than the cost to operate the programs for offering information. Finally, the program that provides marketing information on domestic livestock provides sufficient social benefits, so KAPE should expand these programs.

  • 본 연구는 고령친화용품 체험공간의 확대 설치를 위한 근거를 파악하기 위해 체험공간에 대한 경험유무에 따른 가상가치를 평가하였다. 추정방법은 고령자 152명을 대상으로 조건부 가치측정 방법인 이중경계형(double-bounded dichotomous choice) 로그로짓모형(log-logistic model)과 로그노말모형(log-normal model)을 적용하였다. 추정결과, 로그로짓모형의 절단평균은 3,401원, 평균은 4,937원으로, 로그노말모형은 절단평균이 3,433원, 평균은 4,144원으로 나타났다. 체험공간이 삶의 질과 산업육성을 위해 필요성이 높음에도 지불의사에 대한 부정적 답변이 많았으며 체험공간의 미경험자가 가치를 상대적으로 높게 평가하였다. 체험공간 추가설치의 문제는 체험공간에 대한 가치평가의 제고뿐만 아니라 복합 기능의 도입, 다양한 고령친화용품 구비, 개인맞춤형 지원, 나아가 접근 편의성과 서비스 수준을 제고해야 할 필요성을 보여주었다.

  • 향후 장애인과 고령인구의 지속적인 증가로 인해 교통약자의 통행수요는 확대될 것이며, 이에 따라 고령자, 장애자들이 안전하고 쾌적하게 생활할 수 있도록 지원하는 사회간접자본의 정비가 요구되고 있다. 무엇보다도 대중교통관련 시설의 Barrier-free화(무장애화)는 시급한 사안이라 보아진다. 본 연구의 목적은 공공재의 가치추정에 있어 효율적인 방법론인 이중양분선택형 질문법에 의한 CVM(조건부가치측정법)을 이용하여 지하철 역사의 Barrier-free 시설의 가치를 추정하고, 생존분석을 통해 지하철 이용자들의 지불의사금액에 영향을 미치는 요인을 분석하고자 한다. 본 연구의 결과, 에스컬레이터와 엘리베이터에 대한 평균지불의사금액이 장애인개찰기나 단차해소시설의 평균지불의사금액에 비해 상대적으로 높게 나와 실제 Barrier-free 시설의 확충에 있어서 이용편의시설보다는 이동편의시설을 먼저 시급히 설치해 나가야 함을 시사하고 있다. 또한 각 Barrier-free 시설에 대한 교통약자의 평균지불의사금액이 일반인의 평균지불의사금액에 비해 훨씬 높아 일반인과 비교할 때 교통약자들이 Barrier-free 시설의 가치를 상대적으로 높게 평가하고 있었다.
