The Electronic Shelf Label (ESL) is an alternative to the paper price label attached to merchandise shelves and is attracting attention as a retail IoT infrastructure that will lead the innovation of offline retail outlets. In general, when introducing a substitute product, the company tends to consider the financial factors such as the efficiency of the investment cost compared to the existing product or the reduction of the operating cost. However, considering only financial factors in the decision-making process, it may not properly reflect the various values associated with corporate strategy and the requirements of stakeholders. In this study, 8 evaluation items (Investment Cost, Operating Cost, Quality Level, Customer Management, Job Efficiency, Maintenance, Functional Expandability, and Store Image) based on BSC's 4 perspectives (Financial, Customer, Internal Business Process, Learning & Growth), and using AHP (Analytic Hierarchy Process) to measure the priorities of evaluation items for domestic small supermarket employees. As a result of the research, priority was given in order of Customer, Learning & Growth, Internal Business Process, and Financial aspects among the evaluation items for adopting the price label, and the electronic price label was supported with higher importance than the paper price label. In contrast to the priorities of the financial aspects of most prior studies, the items of Learning & growth and customer perspectives have relatively high priorities. In particular, respondents classified by job group, The priorities of the 8 evaluation items were different among the groups. These results are expected to provide implications for both companies (retail outlets) and ESL providers (manufacturers and service providers) who are considering the introduction of ESL.

Although recent policies and regulations in Korea strongly advocate and encourage cultivation of venture foundations, studies on venture foundation and success are very limited and often primarily focus on entrepreneurship or individual quality as a venture founder in addition to such studies' validity in question. Therefore, this study primarily focuses on venture preparation process which is subject to venture founder's effort to verify the policy effectiveness in the relationship between venture preparation and business performance. Major goal of this study is to reduce social cost of venture failure by suggesting systematic policy support for venture foundations and analyzing the relationship between following variables: first, venture preparation and financial performance, second, venture preparation and non-financial performance, and third, venture preparation and business performance. 400 initial venture foundations less than 5 years are selected from KISED(Korea Institute Startup & Entrepreneurship Development) trend analysis to carry out statistical analysis using SPSS 18.0. To organize the data features, frequency analysis as well as descriptive statistics are performed to verify the hypothesis. As a result, sub-factors in measurement of venture preparation which are venture education period, venture benefit, and experience of incubating organization are selected as independent variables. Likewise, sub-factors in measurement of business performance which are financial performance and non-financial performance are used as dependent variables. To validate interactive effect, venture preparation period is selected as control variable to perform hierarchical regression analysis. The analysis result verifies that venture benefit has positive influence on financial and non-financial performance while venture education period has positive influence on non-financial influence and experience of incubating organization has negative influence on non-financial performance without influence on financial performance. In addition, interaction of venture preparation period has positive influence solely between venture benefit and non-financial performance. Through this study, appropriate supporting plans depending on the level of venture preparation can be derived to improve business performance of initial venture foundations for policy designer of venture support, and quality rather than quality improvement of venture businesses is possible through investigation of structural issues of individual venture businesses. Ultimately, this study suggests venture founders to determine whether to focus on venture preparation process or to start a venture business.

이 논문은 자본시장이 무작위 행보를 운동법칙으로 삼고 있는가, 아니면 정상성의 시계열에 의하여 움직이고 있는가를 심도있게 분석한다. 주가가 무작위 행보를 따른다는 가설을 긍정적 입장에서, 부정적 측면에서, 그리고 이 양자가 공존하고 있다는 관점에서 각 측면에 합당한 방법론을 통한 실증적 분석에 의하여 검정한다. 여러 검증방법을 사용하여 종합주가지수 수익률을 분석하였는 바, 주가 시계열은 무작위 행보가 아니라 정상성의 확률과정(stationary precess) 임이 밝혀졌다. 이와 같은 결과는 우리나라의 증권시장의 성질 중의 하나가 평균회귀라는 것을 입증하는 증거이다. 그리고 평균회귀가 단기적으로 발생하여 그 속도가 매우 빠르다. 주가 시계열에 충격이 가해져 영향을 받을 때 3일 정도가 경과하면 그 충격이 거의 모두 소멸하고 있다. 우리나라 증권시장은 volatility가 높다. 주가는 상당히 높은 자기상관 관계를 갖고 있으며, 이 상관계수가 음수로서 약 -0.50이다. 무척 빠른 속도의 평균회귀와 높은 시계열 상관에 비추어 볼 때 우리나라의 자본시장이 효율적 시장이라는 가설에는 큰 의심이 든다. 뿐만 아니라 이 실증적 결과는 단기적 예측 가능성이 존재할 수 있음을 시사하고 있다. 주가 시계열은 이분산성(異分散性)이 꽤 높다.

This paper test the relationship among determinants of environmental investments, level of environmental investments, eco-efficiency (carbon productivity). The results show that profitability, leverage and R&D costs have a negative impact on environmental investments, and controlling ownership have a positive impact on environmental investments as well as environmental protection costs. The analysis also show that firms increasing environmental investments are able to gain superior environmental performance ($CO_2$ emission), but are negatively relationship with financial performance. Finally, the findings prove that differences exist in the relationship between determinants and effect of environmental investments when grouped by industry characteristics.

The megatrend of convergence in finance, telecommunication, and service industries is being spread over the whole industry. It has generated various kinds of contractual alliance or joint venture. Our paper builds a theoretical model for the profit sharing between two firms that participate in a joint venture. The model shows how the profit sharing rule affects the incentives of the participants, and, eventually, the efficiency. We derive the first-best solution of the profit sharing, where no incentive distortion exists. Then, we compare the incentive-affecting cases with the first best outcome, and assess the efficiency and the fairness of distribution. Our analysis shows that if we properly design the decision-making structure on transfer price and production quantity, we can reach the socially optimal efficiency.

This research outlined the factors influencing the business management success via analyzing a survey of business principles. The research process has been tested in comparison of both financial factors, which come out of objective data and non-financial factors so relevantly prioritized by combining these factors. In order to specify the factors, a check-list and analyzed essential features of category have been done with interviews and surveys. As consequently proceeding, the authors could deduce that non-financial but analytic factors such as business do-able, technician workability, compensation and benefits etc. play major roles in construction sector. The outcomes consider a construction business as fundamental human labor job as opposed to a manufacture business. On reasoning necessarily more objective research works to be done as developing this research's outcome, it is meaningful in suggesting the pivotal factors influencing the construction business management. Therefore, this research is expected to guide the direction to induce the improvement of business management to be done by further exemplary researches.

According to asymmetric information hypothesis (for example, Ross (1977), Myers and Majluf (1984)), the impact of seasoned equity offering (SEO) announcement on the stock price depends mainly on the informational market efficiency. Despite of the importance of this fact, most of the previous SEO-related studies have done under the assumption of equal informational market efficiency among sample firms. This study intends to solve this problematic assumption and explores the real impact of SEO announcement on the stock prices. For this purpose, we divide 122 SEO firms into two subgroups; one with firms from KOSPI200 and the other including firms from the rest of KOSPI, assuming the former is more informationally efficient than the latter. Different from the US market-based study demonstrating short-and long-term negative price impacts of SEO announcement, most of the Korean market-based ones show price increases up until the announcement and decreases just after the announcement and in the long run. These previous studies attribute this difference to the different market system and regulation between them. Our results indicate that this discrepancy can be attributed to the different degree of market efficiency as well as the different market system and regulation.

The 2008 global financial crisis was triggered by the Lehman Brothers crisis caused by the sub-prime mortgage crisis in the United States This crisis has had an impact on the globe's dry bulk shipping market by reducing dry bulk cargo volume. An oversupply of dry bulk carriers caused a serious recession in the globe's dry-bulk shipping industry and shipbuilding industry. In this situation, the Korean dry-bulk shipping companies were victims of the quagmire of a long recession since the global financial crisis and could not overcome this crisis. This condition forced them into severe financial risk Thus, it caused many shipping companies to file for bankruptcy. In this study, we classified Korean ocean-going dry-bulk shipping companies into two groups, that is, the solvent group and the insolvent group. We also separated the research period before and after the 2008 global financial crisis. Then we investigated the differences in the major financial ratios of the two groups by t-test and found that some financial ratios such as profitability ratios and growth ratios showed the difference between the two groups with statistical significance. The significance of this study is as follow. First, the shipping company management is also crucial for the systematic management of financial strength and business strategy, it is crucial to manage cargo which a high profitable freight. Second, the shipping company should be managed as a company with continued growth through efficient operation and management of ships.

This paper uses the Efficient Method of Moments(EMM) of Gallant and Tauchen to estimate continuous-time stochastic volatility diffusion model for the Korean Composite Stock Price Index, sampled daily over $1995\sim2002$. The estimates display non-normality of stock index return, leptokurtic distribution, and stochastic volatility. Funker, this study suggests that two factor stochastic volatility model will be more desirable than one factor stochastic volatility model to estimate daily Korean stock return and also suggests that the stochastic volatility diffusions should allow for Poisson jumps of time-varying intensity.

우리 나라의 금융기관들은 금융환경(金融環境)의 급격한 변화 속에서 일대 전환기를 맞고 있다. 대내적으로는 금리자유화를 비롯한 금융자율화(金融自律化)의 추진, 금융산업의 개편 등의 금융구조 조정이 진행되고 있고, 대외적으로는 국내금융시장에 대한 개방압력(開放壓力)이 가중되고 있다. 본 연구의 목적(目的)은 이상의 다양한 금융환경의 변화 중에서 1991년과 1993년에 실시된 1,2단계 금리자유화조치가 은행의 경영위험에 어떠한 영향을 미쳤는지를 증권시장(證券市場)의 반응을 통하여 규명하고자 한다. 구체적으로 일반적인 예상과 같이 금리자유화로 인하여 은행의 위험이 증가하였는지 아니면 금리자유화가 은행의 자금조달과 운용에 있어서 자율성과 유연성을 확보해 주어서 오히려 은행위험을 감소시켰는지를 실증적으로 검증한다. 주가자료를 이용하는 증권시장의 반응을 통한 은행위험의 분석은 은행에 관련된 재무정보를 신속하고 충분히 반영하는 효율적 시장이며 회계자료를 이용하여 은행위험을 추정하는 방법이 부적절하다는 가정하에서 합리화된다. 은행 위험은 은행감독 당국의 관심대상인 총위험과 은행주식 투자자의 관심대상인 체계적 위험의 두요소를 대상으로 한다. 본 연구의 증권시장반응을 통한 실증분석결과에 의하면 금리자유화조치 이후 은행의 위험은 예상과는 달리 증가하지 않은 것으로 나타났다. 은행총위험은 증가하지 않았으며 체계적 위험은 오히려 2차 금리자유화 이후 하락하는 결과를 보여준다. 이는 금리자유화 조치가 은행의 자금조달과 운영에 있어서 운신의 폭을 넓혀줌으로써 금리 변동폭 증대로 인한 위험증가를 상쇄함을 의미한다. 이러한 결과는 미국의 금리자유화조치에 관련된 대부분의 연구결과와 일치한다. 또한 위험은 개별은행의 재무특성에 따라서 상이한 변화를 보여주었다. 특히 자산규모가 작은 후발은행의 경우 자금조달과 운영의 측면에서의 제한이 완화됨으로써 위험이 감소함을 보여준다. 따라서 정부당국자는 금리자유화의 긍정적 효과를 극대화하는 방향으로 적극적으로 금리자유화를 추진하는 것이 바람직하다.
