Purpose - The purpose of this paper is to empirically investigate the effectiveness of Offcial Development Assistance (ODA) in recipient countries' economy. ODA is designed to mitigate poverty and stimulate economic growth in the developing countries. We classify total ODA into bilateral ODA and multilateral ODA depending on the number of donor countries. If the ODA flows from one donor country to one recipient country, it is classified as bilateral ODA. If the multiple countries simultaneously become donor countries through the international organizations such as United Nations and World Bank, it is classified as multilateral ODA. This paper compares the effect of bilateral ODA and multilateral ODA in determining recipient countries' economic development, and tries to provide policy implications to Korean ODA. Research design, data, and methodology - Our primary explanatory variables are bilateral and multilateral ODA. Private credit in recipient countries is adopted as additional explanatory variables to capture the level of financial development in recipient countries. We measure the ODA effectiveness using economic growth and quality of life of the recipient countries as the dependent variable. We collect 142 recipient countries' data from OECD statistics, during the period from 1970-2014. Panel least squares estimation with country fixed effect is employed as the empirical model. Results - Our results support that ODA variable has a negatively significant impact on recipient countries' economic growth, while it is positively correlated with human development index. Recipient countries' private credit is positively correlated with economic growth and human development index. The interaction variable of ODA and financial development turns out to be significant in general. We find that the positive effect of ODA depends on recipient countries' financial market development and this effect is stronger in multilateral aid than bilateral one. Conclusions - From the analysis, we have confirmed that the recipient countries financial development is the necessity condition to achieve positive effect of ODA. Based on these results, we suggest that Korean government should increase the share of multilateral funding and pay attention to recipient countries' financial market development to maximize the effectiveness of ODA.

Purpose - The purpose of this study is to grasp the concept, characteristics and application status of sharing economy, and to derive a research model based on sharing economic service, and to analyze factors and influences of consumers' intention to reuse of sharing economy. Research design, data, and methodology - The questionnaires were created to examine variables for practical and theoretical implications. After pilot survey, conducted for 24 days from March 10th to April 2st in 2017, total numbers were 377. But 330 copies were used for the analysis with IBM SPSS Statistics 23.0 and IBM SPSS AMOS 23.0. The structural equation model was applied for this. Results - First, sharing economic services remain at an early stage, but it is meaningful to identify the revenue mechanism of the business model of the sharing economic platform. Second, in this study, it is meaningful that we systematized the theoretical structure by examining existing studies on the characteristics of the sharing economic service and consumer characteristics, and by examining empirically. Third, Satisfaction and Reliability are related to the characteristics of Sharing Economic Service (Security, Convenience, Discount, Sharing, Social Interaction), Consumer Characteristics (Personal Innovation, Word-of-Mouth) It is meaningful to broaden the understanding of the factors by verifying the mediating effect. Fourth, the sharing economy business is meaningful in that it is a new consumption trend that changes the meaning of consumption to consumers. Gradually, more and more people are recalling that purchasing something is not consumption, but sharing and borrowing is also consumption. In other words, through the sharing economy, consumers can experience more products and services, have more choices, and are expected to have a positive impact on economic growth by increasing the utilization of idle resources. Conclusions - Currently, the sharing economy is growing rapidly all over the world. Therefore, in the subsequent study, it is necessary to compare Korea and China's sharing economy and study the cultural and social characteristics of Korea and China. In particular, I think that steady research is necessary for more precise and specific direction on the influence of the shared economy.

Purpose - How are gains from trade distributed between countries when economic integration is achieved through free trade? The purpose of this paper is to answer this question. Design/methodology/approach - This study attempts to address the issue of distribution of trade gains between participating countries following economic integration in terms of positive economics. The analysis is therefore based on a theoretical methodology. Findings - First, commodity prices fall and consumer surplus increases in both large and small countries. Second, when economic integration into free trade is achieved, gains from trade always exist in small countries. However, the size of trade gains depends on the degree of difference from the market size of the partner country, the large country. However, the size of the gains from trade depends on the extent of difference between the market size of the large country. If the market size of a large country is much larger and there is a large difference, trade gains will be very large, whereas if the market size is similar, profits of domestic firm will decrease. Therefore, in that case, the size of the gains from trade becomes relatively small because only the gains from exchange exists. On the other hand, in a large country with a large market size, there is a possibility of trade gains only when the market size is similar to that of a small country, which is a trading partner. However, if there is a large difference in market size, the decrease in profits of domestic firm is relatively larger than the increase in consumer surplus due to trade, and rather, a trade loss occurs. Research implications or Originality - Our analysis contributes to filling the gaps in the literature regarding the distribution of gains from trade, and from a policy point of view, it is meaningful in examining the impact of market size, an important variable considered in regional economic integration of countries.

현재 우리나라 식품의약품안전청에서는 $2{\times}2$ 교차설계법을 기초로 제제간의 생물학적 동등성 평가를 수행하도록 규정하고 있다. 하지만 고변동성 제제의 생물학적 동등성 평가에서 $2{\times}2$ 교차설계법에 의한 시험은 지나치게 많은 피험자를 필요로 할 수 있어 윤리적이고 경제적인 고려가 필요하다는 논의가 이루어지고 있다. $2{\times}2$ 교차설계법을 대체할 수 있는 대안으로 $2{\times}4$ 교차설계법은 미국 및 유럽 등에서는 생물학적 동등성 평가에 광범위하게 사용되는 설계 방법이고, $2{\times}3$ 교차설계법도 $2{\times}2$와 $2{\times}4$ 교차설계법의 단점을 개선할 수 있는 효율적인 대안으로 관심이 많다. 본 연구에서는 $2{\times}4$와 $2{\times}3$ 교차설계법의 통계적 모형과 제시된 통계적 모형에 연계된 분산분석표를 유도한다. 현행 국내 생물학적 동등성 시험 규정에 의하면 $2{\times}4$와 $2{\times}3$ 교차설계법의 분산분석표는 반드시 제시되어야 하지만 아직 문헌상에 존재하지 않아 관련 연구에 기여할 것으로 생각된다. 또한 $2{\times}4$와 $2{\times}3$ 교차설계법에 기초한 피험자 계산을 $2{\times}2$ 교차설계법과 비교 제시하여 고변동성 제제의 생물학적 동등성 시험 연구에 적절한 시험 설계 선택에 정보를 제공한다.

Purpose - The purpose of this study is to analyze Korea's trade relations centered on the Pacific Alliance (PA), a major economic integration in Latin America, and identify its problems and suggest measures that can be taken by the government and corporations to reinforce economic cooperation. Design/methodology/approach - To improve the level of contribution of the study, an empirical analysis is necessary. However, due to limited data access, the study will approach the topic of trade relations between Korea and the PA with various statistics and literature. Findings - First, there is an urgent need for changes in import-export goods between Korea and the PA, as trade is focused on specific items. Second, although foreign direct investment from Korea to the PA is centered in manufacturing and mining industries, there should be different investment strategies by countries and industries. Third, it is necessary to reinforce commercial cooperation. Korea currently has Free Trade Agreements with Chile, Peru, and Columbia, but not with Mexico, the largest trading partner among the PA. Therefore, Korea must take active measures to sign an FTA with Mexico, which has been put on hold. Research implications or Originality - Latin America has the most thriving market when it comes to Free Trade Agreements worldwide. With the official establishment of the Pacific Alliance (PA) in 2012, the economic integration of Latin America faced entirely new circumstances. Reinforcing economic cooperation with the PA is extremely important for Korea in terms of entering and dominating the Latin American market. However, there is still a lack of research on the Pacific Alliance, and corporations that aim to enter the Latin American market face difficulties due to lack of information. By investigating the Pacific Alliance and its prospects and analyzing the trade relations with Korea, this study will provide strategic measures for corporations that wish to enter the Latin American market.
