This research investigated the effects of university library users' use patterns and their recognition of service benefits on the magnitude of service value assessments derived from users' statements using contingent valuation method (CVM). Library users' use patterns were operationalized by the number of library visits, library website visit counts and the degree of dependence on their own libraries. User benefits variables were measured by the level of satisfaction on the benefits of library use for teaching & instruction, research & writings, and employment & external activities. University library services were divided into circulation, journal articles (domestic & foreign), reference service, user education, reading room service and WTPs for each service were measured. The results from hypotheses testing show that the number of library visits affect WTP amounts for circulation, foreign article use, reference service and user education. The degree of library dependence seems to affect WTP amounts for circulation and user education. With regards to the hypotheses related to the recognition of library service benefits, the degree of satisfaction for teaching & instruction benefits seems to affect WTP amounts for reading room use.

In this study, we estimate the greenhouse farmers' willingness to pay of agricultural water supply through pipeline. First, in the questionnaire design, orthogonal design and block design were used to enhance the ease of survey. Second, the theoretical model was constructed through the setting of the probability utility function, and the parameters were estimated by using the conditional logit model. Third, all of the estimation coefficients were statistically significant at the 1% significance level. The results of analysis are summarized as follows. First, the probability of selection is increased when maintenance is carried out by Korea Rural Community Corporation or local government. Second, the probability of selection is increased when agricultural water supply through pipeline is higher than the current level. Third, if the Korea Rural Community Corporation carries out maintenance management, the marginal willingness to pay is 44 won per ton. And if the local government carries out maintenance management, the marginal willingness to pay is 25 won per ton. Fourth, according to the quality level of agricultural water supply, the marginal willingness to pay is 101 won, 114 won and 120 won per ton, respectively. This study can be used as a basic data on the cost setting for agricultural water supply through pipeline.

환경개선용수의 비용 부담방법과 부담주체를 결정하는 것은 환경개선용수의 효율적 이용과 관리의 핵심적인 요소이다. 환경개선용수의 비용부담 방법은 공공부담, 수익자부담 및 원인자부담이 있다. 그런데, 비용부담 방법은 환경개선용수의 공급에 대한 댓가를 어떠한 형태로 지불받을 것인가? 환경개선용수의 수익자는 누구인가? 그리고 환경개선용수를 어떤 시각에서 바라 볼 것인지에 따라 달라지게 된다. 즉, 환경개선용수가 순수한 공공재로서 당연히 국가가 제공하여야 하는 기본 서비스인지 아니면 일반 재화나 서비스와 같이 수익자 부담원칙에 의거 수요자가 부담해야 하는지, 또는 공공재와 사적재의 양면성을 고려해 공공부담과 수익자부담을 같이 고려하는 형태가 바람직한 지에 대한 검토를 필요로 한다. 아울러, 환경개선용수의 수익자를 설정하는 문제에 있어서는 수요자가 특정한 목적을 위해 물을 사용하는 특정 사업자인지, 아니면 공익적인 측면에서 불특정 다수를 대신하여 환경개선용수를 수요하는 수요자인지에 따라 수익자가 달라지기 때문에 이에 대한 구분도 필요하다. 환경개선용수의 부담방법을 정할 때 수원(水源)을 기준으로 판단하여야 한다. 환경개선용수의 수원으로는 다목적댐, 하수처리장, 빗물, 농업용 저수지, 지하수 및 기타 하천수로 구분할 수 있다. 아울러 비용부담 범위가 물에 대한 부담에 한정하는지 아니면 환경개선용수를 수익지까지 공급하기 위한 공급시설에 대한 부담인지도 명확히 할 필요가 있다. 환경개선용수는 생활 공업용수 등과 같이 하천수를 특정 용도에 사용하는 것이기 때문에 특정 이용자가 국가에 하천수 사용허가를 얻어 이용하는 것으로 수익자가 비용을 부담하는 것을 원칙으로 하는 것이 가장 바람직하다. 왜냐하면 환경개선용수의 확보가 하천관리청의 의무가 되는 경우에는 하천의 물이 공유재산화 됨으로써 나타나는 '공유재산의 비극'(Tragedy of the Commons)을 초래하기 때문이다. 다만, 비용부담의 정도에 있어서는 다른 요인이 고려될 필요가 있다. 원칙적으로 하천의 자연적 기능을 유지하는데 필요한 유량은 하천관리청의 의무이므로 공공부담으로 하고 인위적 기능을 유지하는데 필요한 유량은 수익자 또는 원인자부담이 바람직하다. 이러한 기본 원칙에 따르면, 환경개선용수는 수익자부담 또는 원인자부담이 주(主)원칙이고 공공부담은 부(副)원칙이다. 본 연구는 환경개선용수의 확보 및 공급에 따른 비용부담 원칙에 대한 기준을 제시한다.

This study conducts a choice experiment to estimate the recreational values of major dam reservoirs in Korea. A discrete-choice econometric model is estimated with the data of experimented choices. Not only the recreation value of each dam lake but also the values of the characteristics of the lakes are estimated. It is shown that the value function of the amount of reserved water is not monotonically increasing. Water quality is the most important characteristic that affects the recreation value. Various other characteristics of the dams such as the availability of education facility, restaurants, hotels and parking lots also generate substantial amounts of recreational benefits.

This study applied the choice experiment (CE) method to measure values of statistical lives from multi-attributed mortality risk reduction choices. The four characteristics of mortality risk (i.e. cause of death, voluntariness of mortality risk, timing of death, magnitude of mortality risk reduction) are utilized to design the alternatives of choice sets. The estimation results for the multinomial logit model show that individuals are willing to pay 27,930 won per year for a change from the status quo to a $\frac{1}{100}$ mortality risk reduction for 10 years, 116,773 won per year for mortality risk reduction associated with adults, 97,682 won per year for voluntary mortality risk reduction, 77,234 won per year for involuntary mortality risk reduction. There were several estimates of VSL related to different attributes of mortality risk. The mean VSLs of infant/child/young adult ranged from 1,165 million won to 1,367 million won. The mean VSLs ranged from 1,631 million won to 1,833 million won for adult, and were between 1,128 million won and 1,330 million won for old person.

A key issue in the development and application of stated preference nonmarket valuation is the incorporation of unobserved heterogeneity in utility models. Two approaches to this task have dominated. The first is to include individual-specific characteristics into the estimated indirect utility functions. These characteristics are usually socioeconomic or demographic variables. The second employs generalized models such as random parameter logit or probit models to allow model parameters to vary across individuals. This paper examines a third approach: the inclusion of psychological or 'latent' variables such as general attitudes and behaviour-specific attitudes to account for heterogeneity in models of stated preferences. Attitudinal indicators are used as explanatory variables and as segmentation criteria in a choice modelling application. Results show that both the model significance and parameter estimates are influenced by the inclusion of the latent variables, and that attitudinal variables are significant factors for WTP estimates.

A green market for a product refers to the market where the more willingness to pay for the product consumers have, the greener is the product. As the green markets begin to spread out, researches have been carried out mostly on the effects of various environmental policy measures such as unit emission standard, environmental taxes as they are applied in the green markets. This paper focus on a different issue in the green markets, that is, the effects of the greener market on pollution emission. We consider two kinds of markets, which are fully or partially covered. In the fully covered market where the products sold are necessities such that all consumers purchase the product, as the market gets greener, the amount of pollution emission decreases. On the other hand, in the partiaily covered market, it is shown that the amount of pollution emission could increase as the market becomes greener. This critically depends on whether the total output decreases or increases as the market turns greener.

Due to the existence of asymmetry of information between doctor and patient, it has been believed that doctor might affect patient's decision making process of purchasing medical care. Based on this notion, doctor's reimbursement method has been suggested as an effective policy device of improving efficiency of patient's medical care use by way of its affecting doctor's practice pattern. By using the Community Tracking Study (CTS) household and physician data set, which includes not only various information on patient's medical care use, but doctor's practice arrangements and sources of practice revenue, this paper investigates the effect of community doctor's characteristics of reimbursement method on community patient's medical care use under the control of patient's socio-demographic characteristics and community doctor's practice type. In the process of estimating econometric model, the endogeneity problem of individual health insurance purchase was corrected by using 2818. And due to the existence of sample selection problem, Heckman's two-step estimation method was used for strengthen the robustness of estimation which was adversely affected by sample selection problem The empirical results show that as the average value of community doctor's portion of practice revenue determined by prospective method out of total revenue increases, the community patient's total out-of-pocket medical cost decreases. This results suggest, as doctor's practice revenues are mainly determined by prospective method, such as capitation, doctors would be more conscious about practice cost, which might affect doctor's practice pattern and by which his/her patient's use of medical care would decrease.

This study aims to compare the experience of selected countries in operating separate payment system for new healthcare technology and to find implications for price setting in Korea. We analyzed the related reports, papers, laws, regulations, and related agencies' online materials from five selected countries including the United States, Japan, Taiwan, Germany, and France. Each country has its own additional payment system for new technologies: transitional pass-through payment and new technology ambulatory payment classification for outpatient care and new technology add-on payment for inpatient care (USA), an extra payment for materials with new functions or new treatment (C1, C2; Japan), an additional payment system for new special treatment materials (Taiwan), a short-term extra funding for new diagnosis and treatment (NUB; Germany), and list of additional payments for new medical devices (France). The technology should be proven safe and effective in order to get approval for an additional payment. The price is determined by considering the actual cost of providing the technology and the cost of existing similar technologies listed in the benefits package. The revision cycle of the additional payment is 1 to 4 years. The cost or usage is monitored during that period and then integrated into the existing fee schedule or removed from the list. We conclude that it is important to set the explicit criteria to select services eligible for additional payment, to collect and analyze data to assess eligibility and to set the payment, to monitor the usage or cost, and to make follow-up measures in price setting for new health technologies in Korea.

We established economic models for economic performance analysis in order to respond to changes in a rapidly changing environment. We tried to maximize business efficiency and performance of science and technology information management distribution project. The science and technology information management distribution project is significantly different from general R&D project. In this paper, it is meaningful to develop economic models to analyze economic outcomes for science and technology information management distribution project. We anticipate that these models will contribute greatly to economic performance analysis for science and technology information management distribution project.
