The change in farmland price has almost always been focused on not only farmers but policy-decision makers; for farmers to get information before purchasing farmland; for policy-decision makers to use appropriate policy tools to stabilize the market. So far the change in farmland price has been calculated as a form of average change on a year-to-year base. Such calculations have become one of the causes which lead to misunderstanding of the farmland market because the year-to-year average change includes changes in price as well as changes in the number of trades and sizes of traded farmland. This paper is designed to suggest a proper method of building a price index for farmland as a tool to review the price change. We considered the applicability of several types of price indices and concluded that a Laspeyres-type price index is the most reasonable choice. A Laspeyres-type price index, however, has a shortcoming in which a reference year's weight may affect the whole period of an index. Thus, we also suggest two other weights, a three-year average including a reference year and a share of farmland. All indices show that farmland prices have risen significantly in recent 10 years. We hope that the indices will be developed into one of the government's formal statistics.

Advancement of science technology, combined with other technologies including smart clothing, enables value added product developments and market creation. Accordingly, it became necessary to identify technology trends promptly and to prepare future technology road map. For this purpose, many bibliometric analysis using thesis and patents have been made. However, few such attempts are made in clothing study. Thus, the study examined the latest technology trends and future technology development directions of smart clothing from empirical bibliometric analysis based on smart clothing patent documents. In addition, comparative analysis was made about the market leadership and technology development capability of core sectors by countries utilizing market reach index expressed as patent families and technology development index. The study revealed that overall smart clothing technology development trends has been continuously increasing since 2000. Also the results confirmed that it is in the development stage from the fact that each year the number of patents and patent applicants in portfolio analysis also has been increasing. In addition, comparative results of patent market share and market reach index, with the highest in electronics/ICT technology sectors, indicated that this is the technology sector with competitive acquisition of comparatively advanced technology and market expansion. The analysis methodology of economic value of technology including the presented market reach index in this report is expected to be utilized in the process to identify the current positioning of core technology and future development direction.

This research examined a task to foster into the export industry, through analyzing the competitiveness of the ornamental fish industry and identifying the position of Korea's ornamental industry in the world. Ornamental fish in Korea holds the world's leading aquaculture technology, but products are limited to a few species, lacking competitive products. In the case of aquarium supplies, the Korean technology level is receiving relatively positive marks in the global market, but ornamental fish products are lagging behind the global trend. In other words, Korea's ornamental fish industry has the overall technical foundation, but lacks differentiation in the global market. Meanwhile, Korea's market share of world trade market in fishery products is minimal. Growth was also analyzed not high compared to other countries. Various trade competitiveness index results rated very low in competitiveness, but it is hard to compare Korea with other countries which have already built a strong foundation in the ornamental fish industry. Therefore, for the mid to long term Korea should adapt a "Choice and concentration" strategy and focus on the production of ornamental fish and aquarium supplies, which will enable Korea to become differentiated in the global market and capture the world exports.

This paper is an attempt to analyze the comparative advantage of Busan Port to China. For this, we use the market comparative advantage index, which is a version of the revealed comparative advantage index. The market comparative advantage index (MCA) uses trade patterns to identify the sectors in which a region has a comparative advantage, in this case by comparing Busan Port's trade profile with the world average (China). The indices are calculated at the commodity level of the HS four-digit classification. The export data used in this study are obtained from the Korea International Trade Association. Exports to China accounted for almost one third of Korean exports in 2014. There are, however, structural differences among the main export items of Busan Port. This paper, therefore, employs MCA indices to reveal the behaviors of the ten main export items, which are "HS3920-other plates/sheets/film/foil of plastics," "HS7606-aluminum plates/sheets/strip," "HS8479-unspecified machines/medical appliances," "HS8486-machines for semiconductor devices or wafers," "HS8529-parts for transmission apparatus for television," "HS8703-motor vehicles for the transport of persons," "HS8708-parts of motor vehicles," "HS9001-optical fibers," and "HS9013-liquid crystal devices." The study shows that export competitiveness of nine items increases, the exception being HS8703. However, China's import ratios of seven of the nine items for which the MCA indices go up are on the decrease, which means that it would be hard to expand the export market for these seven items, despite the higher MCA indices. Since the shares of the port's total exports to China of HS3907, HS8486, HS8529, HS9001, and HS9013 in total exports to China increase together with China's import ratio decreasing, these items may have promising export markets. MCA increases of HS7606 and HS8479 are attributable to China's lower import ratio, rather than a higher export share, so higher MCA indices do not guarantee higher export competitiveness for these items.

Korean movie maintain their market share from the highest 59.7% to the lowest 42.1% during the last ten years in Korea. However, with the multiplex and wide release strategy, the monopolies of four major distribution companies and three multiplex chain, the polarization of Korean movie's Box Office performance is deepening. With Gini-Index, concentration of film admission has been deepened in intensity from 0.53 in 2004 to 0.85 in 2014. Using Thomas Piketty's method, Movie attendance proportion of Highest 10% of the box office ranking for 2014 sharply increased to 71.2% from 30.28% in 2004 and the lowest 50% of box office ranking dropped from 11.03% in 2004 to 0.08% in 2014. Concentrations of the number of Screen, Screening, the seating Capacity have the same analogy with the polarization of film admission. However, concentration of seating share has maintained a modest increase from 0.22 in 2004 to 0.38 in 2014. This analysis shows that polarization of Korean movie box office performance is not the sole result of Natural selection of market but the result of the monopolies of distribution companies and Multiplex chains.

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.
