서브프라임 금융위기 이후 주택시장이 침체되면서 2000년대 초반과 같이 주택투자로 고수익을 올릴 수 있는 시기는 앞으로 찾아오지 않을 가능성이 이제 점차 높아지고 있다. 이에 따라 과거 고수익의 원천이 되었던 부동산 시장은 점차 수익형 부동산 등 안정적 수익을 획득할 수 있는 투자시장으로 변모하고 있다. 이에 따라 대표적인 간접투자상품인 리츠의 시장규모는 더욱 커질 것으로 판단된다. 그러나 아직까지 리츠시장은 일반적인 주택투자시장 및 금융시장보다 훨씬 더 그 성장이 미미한 실정이다. 하지만 포트폴리오 이론을 토대로 한 위험관리의 중요성이 투자의 매우 중요한 개념을 자리잡고 있는 바 리츠의 안정적인 수익 창출은 포트폴리오의 위험관리에 효과적일 것으로 판단된다. 이러한 관점에서 본 논문에서는 주식시장의 다양한 업종들 중 상대적으로 안정적인 수익을 확보할 수 있는 리츠가 포트폴리오에 편입되었을 때 위험 분산 효과를 실증분석하는 것을 목적으로 한다. 분석결과에서 확인할 수 있듯이 대표적인 경기방어주인 음식료업종과 마찬가지로 리츠업종 역시 전체 시장을 나타내는 코스피와 상관계수값이 상대적으로 낮은 것으로 나타났으며 최소분산포트폴리오로 구성했을 경우에도 표준편차가 매우 낮게 나오는 등 음식료업종과 같이 투자포트폴리오에 편입했을 경우 위험분산 효과를 기대할 수 있을 것으로 판단된다. 투자시장은 향후 미래의 불확실성에 따라 항상 위험을 감수해야 함에 따라 위험 대비 수익이 어느 정도인지가 매우 중요하다. 이러한 관점에서 리츠를 활용하여 포트폴리오를 구성할 경우 위험분산 효과를 획득할 수 있는 바 충분히 그 투자 효용성을 가지고 있을 것으로 판단된다.

본 논문의 연구목적은 국내 회사채시장에서 시장전체의 체계적 위험 (systematic risk)과 각각의 고유위험(idiosyncratic risk)이 회사채 수익률에 미치는 영향을 분석하고자 한다. 2001년부터 2014년까지 채권시장의 자료를 분석하기 위해, 본 연구는 체계적 위험의 대용변수로 기존의 연구에서 사용된 회사채수익률 기간구조 요인(term factor)과 지급불능 요인(default factor) 등을 사용하고, 고유위험의 대용변수로 듀레이션(duration)과 신용평가등급 요인을 선정하였다. 이러한 요인들이 채권의 수익률에 미치는 영향력을 횡단면 회귀분석을 통해 분석한 결과, 체계적 위험과 관련된 요인들은 통계적 설명력이 있는 것으로 나타났다. 반면에 회사채 고유위험과 관련된 요인들은 기존의 국내 연구와 달리 회사채 수익률을 통계적으로 설명하지 못하는 것으로 나타났다. 이러한 결과는 본 연구의 분석기간이 기존 연구의 7년 자료보다 긴 14년간의 자료를 사용하고 최근의 기간까지 확장했다는 점 때문에, 오히려 미국의 연구결과와 유사한 것으로 나타났다. 이는 우리나라 채권시장이 IMF사태 이후 국제화가 확대되어 선진국과 동조현상을 보이는 것으로 해석된다. 따라서 본 연구는 국내 채권투자시장에서도 선진국의 경우와 마찬가지로 개별 채권의 특성보다는 채권시장 전체의 위험에 보다 더 집중해서 투자할 필요가 있다는 점을 제시하고 있다.

As the government announced Real Estate Policies on August 02, most areas except for Seoul cities face increasing business risks. Moreover, the government control over financial sectors' loan leads to the highly possible contraction of new distribution markets. The market trend could bring about the reduction of new demand in PF (Private Financing) business that large construction companies mainly concentrate on, and even the business already obtained has a high risk of being distributed, which could result in substantially low profitability. The currently unstable financial structure of most construction companies is caused by the hike of the prime cost of foreign plants except for that of a few construction companies. If PF (Private Financing) business also faces a difficult situation in such a financial condition, even large construction companies come to have the high possibility of a deficiency in credit rating. Accordingly, the major business that large construction companies concentrate on needs the sufficient business review. It is desirable to make a bid for business guaranteeing stability rather than business solely in consideration of profitability, when participating in a competition for a new construction contract.

During the last ten years, there have been many studies related with settlement and reinvigoration of CM. These researches have shown that the application of CM has been not reinvigorated in Korean construction industry yet, because of some problems such as the insufficient application of the public sector, the policy matters and the CM fee estimates. But the present condition data of the Korean CM Market shown in these studies was insufficient for the standpoint of Market itself. Also, some of these studies compared the Korean CM Market with The America CM Market, to study the foreign CM markets. However, because the Korea CM Market only has the CM for Fee Market but the American CM Market has the CM for Fee and the CM at Risk, the Korea CM Market must be not only compared with the America CM Market but also compared with the America CM for Fee Market. Therefore, the purpose of this study is to determine the present condition of the Korea CM Market through the compare and contrast of the Korean CM Market, American CM Market and American CM for Fee Market, by the Market Growth rate and Market Share. This study further aims to verify whether Korean CM market was implemented.

In a demand response (DR) market run by independent system operators (ISOs), load aggregators are important market participants who aggregate small retail customers through various DR programs. A load aggregator can minimize the allocation cost by efficiently allocating its demand response resources (DRRs) considering retail customers' characteristics. However, the uncertain response behaviors of retail customers can influence the allocation strategy of its DRRs, increasing the economic risk of DRR allocation. This paper presents a risk-based DRR allocation method for the load aggregator that takes into account not only the physical characteristics of retail customers but also the risk due to the associated response uncertainties. In the paper, a conditional value-at-risk (CVaR) is applied to deal with the risk due to response uncertainties. Numerical results are presented to illustrate the effectiveness of the proposed method.

According to globalization and localization of world economics international trade payment method was also changed. A traditional payment was Letter of Credit basis, however it is being increased to various methods such as remittance, documentary collection(D/P, D/A) and open account. In order to acquire a secure export payment, exporters prefer to L/C basis which is guaranteed by a reliable bank. However, the L/C should bear a security so that importers would rather documentary collection than L/C. The reasons for the preference of collection payment rather than L/C are a low commission cost, the conversion of buyer's market from seller's market due to severe competition in the world market, transaction increase between main office and branches and a right to control the goods until executing the payment by exporters. Besides of them, collection payment can handle safer and faster than open account basis. However, the collection payment has a risk which it isn't guaranteed by bank for the payment so that I would suggest countermeasures to minimize the payment risk utilizing the collection basis as follows; using export credit insurance system, a large domestic credit report provider such as D&B for absolutely fresh and new information, a collection proxy service for overseas deferred credit and suggestion specifying to order B/L not straight one on consignee in order to transfer the right of ownership with endorsement without problem.

This study suggests an integrated theoretical framework for the relationship between political risk and multinational corporation (MNC) subsidiary's performance in the emerging market. The political risk would have a negative impact on MNC subsidiary's performance in the emerging countries that are developing in Asia, the Commonwealth of Independent States, Africa, and South America. The major reason is that political risks could generate a loss of benefit or a loss of control for MNC's subsidiary. In this study, I suggest that corporate social responsibility (CSR) strategy would be a solution to overcome various political risks. Specifically, the affiliated firms with diversified industries or greater financial resources could mitigate the negative impact of political risk than unaffiliated firms. Because they can use their tangible or nontangible asset such as information, technology, and construction in order to gain legitimacy and trust from local government, local community, and local firms in the emerging market. Finally, I claimed the costs of the affiliated firms would exceed the benefits at the initial stages, while the benefits of affiliated firms would exceed the costs over time when political risks become higher. The reason is that the trust gained from local stakeholders accumulates over time and the impact of CSR strategy would become an important solution to overcome the risks in and unstable context.

Cloud computing has increasingly been drawing attention these days. Each big company in IT hurries to get a chunk of meat that promises to be a whopping market in the future. At the same time, information is always associated with security and risk problems. Nowadays, the handling of these risks is no longer just a technology problem, with a good deal of literature focusing on risk or security management and framework in the information system. In this paper, we find the specific business meaning of the BMIS model and try to apply and leverage this model to cloud risk. Through a previous study, we select and determine the causal risk factors in cloud service, which are also known as CSFs (Critical Success Factors) in information management. Subsequently, we distribute all selected CSFs into the BMIS model by mapping with ten principles in cloud risk. Finally, by using the leverage points, we try to leverage the model factors and aim to make a resource-optimized, dynamic, general risk control business model for cloud service providers.

로보어드바이저 서비스 제공업체가 금융시장에서 거래되는 ETF를 주력 투자대상으로 집중하고 있다. 이처럼 ETF가 활성화되고 있지만 ETF 위험관리에 관한 연구들은 이뤄지지 않고 있는 상태이다. 본 연구는 변동성의 구조적 변화를 반영한 ETF 손실추정과 ETF 위험관리모형을 평가하였다. 결합 검증통계량 분석결과, GARCH와 마르코프 국면전환 GARCH모형이 시장위험을 적절하게 나타내 주었다. 특히 마르코프 국면전환 GARCH모형이 GARCH모형에 비해 낮은 위반율을 보일뿐 아니라 초과발생들이 독립적이기 때문에 마르코프 국면전환 GARCH모형이 GARCH모형에 비해 좀 더 ETF VaR에 권고될 수 있다.

In an electricity market, the spot market is normally integrated with a forward or future market. The advantage of the forward market is to allow the market participants to deal in a part or the whole trading portfolio at a fix price in advance and to avoid risk associated to the uncertain price of the spot market. Japan has introduced a continuous auction base forward market from April 2005. This paper analyzes the Japanese forward market rules and operations, and introduces a new algorithm that may improve the efficiency of the market itself. The proposed algorithm enables us to give consideration to the specific characteristics of the power system and to integrate them in the auction mechanism. The benefits of the proposed algorithm are verified on an electronic simulation platform and the results described in this paper.
