본 연구에서는 스마트폰의 확산에 가장 주요한 요인이며 다양한 기능성 편의를 제공하는 앱을 구매하는 채널인 앱 마켓을 선택하는 요인을 합리적인 선택 이론 관점을 도입하여 실증적으로 밝혀내었다. 281건의 설문 결과 분석을 통해, 이익의 관점에서 사용편의성과 구조적 보장이 앱 마켓 선택에 유의미한 영향을 주는 것으로 검증 되었다. 반면, 고객신뢰, 정보 품질, 마켓 이미지는 앱마켓 선택에 유의미한 영향을 주지 못하는 것으로 파악되었다. 특히, 국내 앱마켓 플랫폼 제공자(KT, LG U+)의 경우, 해외 앱마켓 플랫폼사업자(구글)에 비해, 고객센터 운용, 피해보상 규정 등 구조적 보장 측면에서 우위에 있는 것으로 보인다. 하지만, 구글 앱 마켓의 경우는 모든 안드로이드 폰에 사전 설치되어 통신사 별로 타 앱마켓을 이용하기 위해 추가적으로 설치해야하는 불편함이 없어 국내 제공자보다 사용자 편의성에서 우위에 있다고 판단된다. 이는 국내 앱마켓 플랫폼사업자에게만 불리하게 작용하고 있어, 정책적 해결점 마련이 필요하다. 사업자비용의 관점에서는 금전적인 전환 비용과 비금전적인 전환 비용 모두 앱 마켓 선택에 유의미한 영향을 주는 것으로 나타났다. 특히, 비금전적인 전환 비용은 국내 앱마켓 플랫폼사업자에게 부정적인 영향을 주는 것으로 나타났다. 이는 국내 앱마켓의 서비스 기대 수준이 낮다고 인식되어 있고, 신규 사용자가 사용하기 위해 회원 가입 등 소요되는 시간적 비용요소가 크다고 인지되어 있다고 설명될 수 있다. 국내 앱 마켓 사업의 활성화를 위해 개선이 필요한 항목으로 보인다. 본 연구를 통해 기존 대부분의 연구들이 앱 선택 요인에만 집중되었다는 한계를 극복하고 앱 마켓 선택 요인을 밝혀내었다는데 본 연구의 의의가 있다고 볼 수 있겠다.

Transmission mechanisms of volatility between two crude oil markets (WTI and Brent markets) have drawn the attention of numerous academics and practitioners because they both play crucial roles in portfolio and risk management in crude oil markets. In this context, we examined the volatility linkages between two representative crude oil markets using a VECM and an asymmetric bivariate GARCH model. First, looking at the return transmission through the VECM test, we found a long-run equilibrium and bidirectional relationship between two crude oil markets. However, the estimation results of the GARCH-BEKK model suggest that there is unidirectional volatility spillover from the WTI market to the Brent market, implying that the WTI market tends to exert influence over the Brent market and not vice versa. Regarding asymmetric volatility transmission, we also found that bad news volatility in the WTI market increases the volatility of the Brent market. Thus, WTI information is transmitted into the Brent market, indicating that the prices of the WTI market seem to lead the prices of the Brent market.

Purpose This study investigates the effects of trust and distrust on intention to purchase in open market, based on the idea that trust and distrust can co-exist. Specifically, this study approached the effects of trust and distrust of the open market on the intention to purchase from a two-dimensional perspective, and examined trustworthiness as the antecedents of trust and distrust. Design/Methodology/Approach In this study, we conducted a questionnaire survey on consumers who have actually purchased a product from open markets in Korea for two months. As a result, 141 users are chosen for the sample. We apply PLS (Partial Least Squares) structural equation modeling (SEM) to verify our theoretical model using the software application SmartPLS 3.0. Findings First, trust in open market positively affects intention to purchase, whereas distrust in open market negatively affects intention to purchase. Second, the three antecedents of trust (i.e. three factors constituting trustworthiness such as ability, benevolence and integrity) affect trust in open market. Third, integrity negatively affects distrust in open market. Since integrity plays an important role in building both trust and distrust in open market, the operators of open market should pay attention to managing their integrity.

The aim of this study was to forecast the future Health Functional Food (HFF) market trends of Korea by studied about policies and market situation in Japan. The HFF is a food that is given an additional health function. In contrast with traditional foods, the HFF has unique characteristics in that it can be produced under the political regulations. The market size of the HFF was growing gradually due to the increased of an aging population and consumer need for high quality and diversified foods. The reason why the HFF market in Japan grew up earlier than other countries, Japan was the first country that institutionalized the HFF policies. Therefore, in this paper, by examining the policies and the market situation of Japan through literatures, we forecasted upcoming political and market situational changes of Korea's HFF market. We noticed that consumers needs about the HFFs which diversified, confidently ensured safety and ingredients will increase. In this regard, the government will reorganize legislation in order to increase the confidence of the safety of HFFs. In addition, the market size of domestic HFFs which are produced by major food companies will grow.

This study examined the market efficiency of korea stock market by comparing variance ratios(VR) of stock groups which is sorted by market capitalization. We compute variance ratios of KOSPI large capitalization, midium capitalization, and small capitalization for 546 trading days from 2006/01/02 to 2008/04/15. For our study, we also use high frequency data that is; intra-day 1 minute data. The characteristics of variance ratios of stock groups by market capitalization as follows: From 1 to 5 minute interval, variance ratios of three stock group increase far from zero(0). The longer time interval, the more variance ratios decrease, but only large capitalization converge on around zero. This means that the market of large capitalization is more efficient compare to other stock groups. The entire sample period can be divided two sub-period because the impact of sub prime crisis arised from U.S.A. influences Korea stock market. Before sub prime crisis, the VRs of mid cap and small cap do not converge on around zero except large cap although the time interval is longer. After sub prime crisis, the VRs of three stock groups decrease when time interval is longer, but only large cap converge on around zero. We conclude that large cap is more efficient than other stock groups in Korea Stock Market.

It is true that traditional markets have become a great foundation for changes in today's production and distribution. However, with the development of science and information communication gradually, the perspective of distribution has been newly developed. In particular, the digital economy system and the pursuit of perfect competition in the global era have placed a great burden on the traditional market. Accordingly, the government has made numerous efforts to revitalize traditional markets, which has led to the present day. However, the change in production, distribution, and transactional perspectives of newly introduced e-commerce in the position of not being able to deviate from the characteristics of the traditional market, that is, the traditional market, poses another major crisis. Therefore, while maintaining the tradition of the traditional market, the introduction of a new method of electronic trading has a good advantage to become an advanced market, but it has not pursued major changes due to fundamental management methods and small-scale operation. Therefore, I believe that it is urgent to introduce and apply new e-commerce to secure transitional competitiveness in order for the traditional market to be reborn and to pursue change and development into a new advanced market.

The paper examines the impact of information about cash flow from operating activities of firms listed on Vietnam's stock market to the decision making of individual investors. Data were collected from interviews with 160 individual investors about their investment decisions based on information on profit growth and cash flow growth from operating activities. T-test was conducted to research on Vietnam's stock market - a market considered as information that is not really public, transparent and ineffective. The research results show that: (1) investors do not care about cash flow from operating activities when making investment decisions if the company's profits grow positively, (2) information about cash flow from operating activities only affects the decisions of individual investors once profit growth is negative, and (3) conflicting information between profit growth and cash flow growth from business activities significantly affects the confidence and comfort of investors in Vietnam's stock market when they make investment decisions. Then, the study points out the mistake of investors when making investment decisions, and offers recommendations to investors when making investment decisions, not only concerned with profit growth, but also paying special attention to cash flow growth, especially cash flow from the company's business operations.
