The combined heat-and-power (CHP) plant is recently suggested as an effective resolution in response to recent rising oil prices and the Kyoto Protocol. This research provides a model for economic appraisal to evaluate CHP investment. Real option model is developed to incorporate a case where the investment is irreversible and underlying revenue is stochastic. The analysis shows that power plant capacity more than 40 Gcal makes CHP investment profitable while the results may vary 10 modest level with respect to investment cost, heat sales price and discount rate.

The reliability of technology valuation depends on, among other things, the reliability of the discount rate estimate. The weighted average cost of capital, generally accepted as discount rate, consists of cost of equity and cost of debt. The model used to estimate the cost of equity for publicly traded firms can not be used directly for small-sized venture firms. In addition, the estimation of cost of debt become very difficult, given the limited and volatile price history, because these small-sized venture firms do not have associated credit ratings. Since two kinds of cost of capital for the small-sized venture firms can not be estimated directly from market data, this study suggests statistical frame works for estimating unknown two kinds of cost of capital. The estimates of underlying cost of capital will help determine the size of appropriate discount rate with logical and scientific way when the technology valuation for small-sized venture firms is made. This study also suggests the necessity of the risk premium for the technology competitiveness to improve the estimation of the appropriate discount rate for small-sized venture firms.

The purpose of the study is to identify the characteristics of films to be exported into a larger market abroad, especially the Japanese film market which occupies more than a half of the export costs of the Korean movies. Our analysis shows that the factors such as the reputation of a director and actors in Japan, the box-office record in Korea and genres have influence upon the export to the Japanese market. Among genres, comedy movies were less exported, while melodramas was more. We expect that this result will be helpful when film producers plan movies for export from the stage of pre-production.

This study intends to analyze the acquisition process in public libraries. It specifically attempts to survey the collection development policy, staff structure of acquisition departments, overall process of book purchasing, conclusion of contract for book purchasing and discount rate of book. Data are drawn from a survey with 315 public libraries in the country. As a conclusion, this study discusses such as current situation in book purchases in public libraries and possible impetus toward a better collection development process.

This study examined: 1) the effects of fashion luxury product price discounts in social commerce on perceived benefit and purchase intention, and 2) differences in such effects by social commerce trust, brand and design preferences for luxury products as well as social commerce and online luxury product purchase experiences. Three discount rates representing high, mid, and low for a luxury product sold in social commerce were manipulated and tested on female consumers and 486 online responses were analyzed. The results revealed that the price discount affected perceived benefit but did not affect purchase intention. Benefits were highly perceived at high and mid discount rates compared to the low rate. Social commerce trust, brand preference, and design preference affected perceived benefit and purchase intention, but the interaction effect with price discount was observed only in the design preference to perceived benefit. The purchase experience of online luxury products also affected purchase intention. Implications from the results were also discussed.

The aim for this study is to suggest a practical model to measure the financial values of the achievements from corporate research and development(R&D) projects. Performance indicators for R&D projects were identified from the extensive literature reviews and the evaluation methods to convert them into financial values were proposed to overcome the problems of excessive predictions and subjective expert assessments in existing methods. The proposed model was applied to R&D projects of an IT company in Korea for its validity test. The model is expected to be a turning point in economic evaluation of corporate R&D projects in general due to its practical and reasonable scheme.

The physical factor having a great influence among components of making values of profit model in apartment houses is equilibrium change of house and this study suggests an alternative of remodelling. It sets profit models including model dividing household of large scale into that of small scale using value making factor of apartment house and spatial composition techniques and model integrating households of small scale and converting them into those of large scale and finds that its economy is good as over 'average', evaluative value of economy is reduced as discount rate increases and economy of remodelling is superior.

The cost of low-income groups's housing expenses have been weighting since 2000. To solve this problem, governments encourage supplying rental apartments for them. House rental supplement is most common things to solve housing problem in an advanced country but there is neither earning rate nor assessment standards in our country. Therefore, studies on house rental supplement are required to develop this systems. Hence in this study, we try to suggest both proper house rental charge to encourage nongovernmental construction and house rental supplement, considerng ability to pay.

Since so many potentials of services, applications, marketing and regulation, it is difficult to decide the fair pricing scheme of network services. However, these considerations are not particular to the operation of a communications network, which is closely related to technological constraints for QoS guarantee. In this paper, the power spectral analysis of MPEG video based on the P-MMBBP model is discussed in the manner of the QoS degradation to the packet delay. As a consequence of the QoS-degradation, a new fair-pricing scheme with the discount factor is proposed. As a result, the proposed scheme shows good characteristics to guarantee the fairness of the charging in the Internet wide-area network.

Due to the uncertainties resulting from cost projection, evaluation over long term period, and adequacy of applied discount rate, the economic assessment for back-end fuel cycle is different from each organizations or individuals. In this paper, the features and limitations of some noticeable economic evaluations were investigated and analysed to contribute for the public participation and back-end fuel cycle policy related researches. As a result of analysis, we found that the reprocess and recycling is more economical than direct disposal option, but the result includes high uncertainty that depends on the input parameters.
