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.

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.

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.

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 한강 수계의 수변경관 및 생태계의 보전 가치를 이중양분선택법에 의한 조건부 가치평가법 (Contingent Valuation Method, CVM)을 사용하여 추정하였다. 음이 아닌 지불의사를 구하기 위해 지수지불의사 모형을 사용하였는데 이 모형이 특히 이중양분선택법에서 매우 중요한 것으로 분석되었다. 한강수계권역의 경관 및 생태계 보전에 대한 총 지불의사는 연간 약 7,055억원으로 추정되었다. 이는 한강 등 수계권역의 수변경관 및 생태계 보전을 위하여 필요한 예산규모가 더욱 확대될 필요성이 있음을 시사한다고 해석된다.

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.

This research was conducted to estimate the use and preservation values of Jirisan national park, using a dichotomous choice contingent valuation. Jirisan national park was estimated to have the use value of 6,377 won per visitor. In terms of preservation value was estimated 13,030 won per housed per year. The results of this research show that Jirisan national park generated considerable use and preservation values, exceeding far greater than current admission fees. The findings also indicate that the estimated economic value provides enough justification for the national park service to increase admission fees in order to maintain the quality of the natural environment. This result may contribute to guidance on the pricing policy of national park managers and practitioners, although public policy may be made in the political arena.

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.

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.

As an alternative to classical maximum likelihood approach for analyzing dichotomous choice contingent valuation (DCCV) data, this paper develops a Bayesian approach. By using the idea of Gibbs sampling and data augmentation, the approach enables one to perform exact inference for DCCV models. A by-product from the approach is welfare measure, such as the mean willingness to pay, and its confidence interval, which can be used for policy analysis. The efficacy of the approach relative to the classical approach is discussed in the context of empirical DCCV studies. It is concluded that there appears to be considerable scope for the use of the Bayesian analysis in dealing with DCCV data.
