In this study, we empirically scrutinize the relationship between short selling transactions and stock price behaviors using the stock market data in Korea during the period from January 2005 to March 2016. We chose the short selling volume ratio (SVR), stock lending volume ratio (LVR), and stock lending open interest ratio (LIR) as variables of the short selling trading activities. We construct portfolios based on the percentile of the short selling volume ratio during the sample period; upper-10%-SVR portfolio, upper-25%-SVR portfolio, upper-50%-SVR portfolio. We estimate the monthly firm-specific return and monthly skewness of the daily firm-specific returns of each portfolio. The firm-specific return or skewness is specified as a dependent variable and the short selling activities as explanatory variables. The results show that all of the statistically significant estimates of the short selling activities for the firm-specific returns are negative and that all of the statistically significant estimates of the skewness of the short selling activities are positive. These results support the hypothesis that short selling activities cause the stock price to decrease.

Korea's trading volume is expected to surpass USD 1 trillion in 2011. Korean economy achieves this largely due to its dependence on export and enhanced technological capacity and product quality. Improved recognition of Korean enterprises in the global arena also helped. However, the largest reason behind theses could be found in exporters' ceaseless marketing endeavors and continued government supports. Today, more and more people become to rely on trade exhibitions to boost export effectively. Trade exhibitions are employed as a useful tool to attract buyers and enter a market. This is because such exhibitions' marketing effect and professional aspects. South Korean export relies on large conglomerates for most part. However, 95% of the country's entire industry are small and medium-sized companies. This means that SMEs' export has a huge impact on the national economy. Therefore, as a way to improve SME export and minimize their losses, we need to use trade exhibitions more actively. The overseas policy insures only promotional activities regarding foreign exhibition and fair (including international events held in Korea), foreign distributor, shopping mall, home shopping, etc. and does not include air fare, traffic cost in the local place, accommodation cost and dining expenditures as costs to be excluded mentioned above. It is not easy for them to take part in events abroad if they have to pay for such expenses. If full financial support is difficult, the Korea trade insurance corporation still may give a certain level of aid for successful exporters to engage in marketing activities abroad more actively and further stimulate SMEs' export.

Purpose: The AEO (Authorized Economic Operator) program, created in 2001 in the United States due to 9.11 terrorist's attack, fundamentally changed the trade environment. Korea, which introduced AEO program in 2009, has become one of the world's top countries in the program by ranking 6th in the number of AEO certified companies and the world's No. 1 in MRA (Mutual Recognition Agreement) conclusions. In this paper, we examined what trade-economic and non-economic effects the AEO program and its MRA have in Korea. Research design, data and methodology: In this study we developed a model to verify the impact between utilization of AEO and trade-economic effects of the AEO and its MRA. After analyzing the validity and reliability of the model through Structural Equation Model we conducted a survey to request AEO companies to respond their experience on the effects of AEO program and MRA. As a result, 196 responses were received from 176 AEO companies and utilized in the analysis. Results: With regard to economic effects, the AEO program and the MRA have not been directly linked to financial performance, such as increased sales, increased export and import volumes, reduced management costs, and increased operating profit margins. However, it was analyzed that the positive effects of supply chain management were evident, such as strengthening self-security, monitoring and evaluating risks regularly, strengthening cooperation with trading companies, enhancing cargo tracking capabilities, and reducing the time required for export and import. Conclusions: When it comes to the trade-economic effects of AEO program and its MRA, AEO companies did not satisfy with direct effects, such as increased sales and volume of imports and exports, reduced logistics costs. However, non-economic effects, such as reduced time in customs clearance, freight tracking capability, enhanced security in supply chain are still appears to be big for them. In a rapidly changing trade environment the AEO and MRA are still useful. Therefore the government needs to encourage non-AEO companies to join the AEO program, expand MRA conclusion with AEO adopted countries especially developing ones and help AEO companies make good use of AEO and MRA.

Global aviation is projected to grow in demand by an annual average of 4.1% between 2014 and 2034. It can be said that environmental impact from aviation will therefore be expected to increase on a similar scale. As regards civil aviation emissions, the sector contributes between 2~3% to International aviation GHG emissions. In the European Union(EU), aviation emissions account for about 3% of the EU's total green house gas emissions, of which a majority are said to come from international flights. In terms of traffic volume in 2013, Korea's international aviation industry 11th with regard to passengers and 3rd with regard to cargo, attaining the overall rank of 5th in the world. GHG emissions has been increasing steadily over the last 4 years, averaging 3.9 percent a year, due to the growth of low cost carriers and the increased demand for air transportations. As for aviation in Korea, there are a number of means intended to attain the Government's emission control objective in an efficient manner, such as AVA (Agreement of Voluntary Activity), TMS (Target Management System) and ETS (Emission Trading Scheme). In addition, the Government intends to better adapt to ICAO's Global MBM(Market-based Measures) that will come into performance on Year 2020. In the study, we focused on GHG mitigation measures that is fulfilling the AVA, TMS, ETS in the Government and suggest the effective measures to reduction the aviation GHG emissions.

Ginseng is being distributed in 35 countries around the world and there are differences by each country in the distribution volume and amount. However, since there is no accurate statistics on production and distribution amount by each country, it is very difficult to predict the world ginseng market. Ginseng trading companies and governments are in desperate need of comprehensive data that shows the world ginseng market status for sales and marketing. For that reason, this study will look into the approximate size of the world ginseng market based on recent ginseng distribution amount by each country and production by major ginseng producing nations. In addition, the review sets an opportunity to check the status of ginseng (Korea) in the world and presents future direction by examining recent history of ginseng development in Korea, which is one of the world's largest ginseng distributers. Since ginseng is cultivated in limited areas due to its growth characteristics, ginseng distributing countries can be divided based on whether they grow it domestically or not. In general, four countries including South Korea, China, Canada, and the US are the biggest producers and their total production of fresh ginseng is approximately 79,769 tons which is more than 99% of 80,080 tons, the total ginseng production around the world. Ginseng is distributed to different countries in various forms such as fresh ginseng, dried ginseng, boiled and dried ginseng (Taekuksam), red ginseng and the related products, etc. and is consumed as food, dietary supplements, functional food, medical supplies, etc. Also, the world ginseng market including ginseng root and the processed products, is estimated to be worth $2,084 million. In particular, the size of the Korean market is $1,140 million which makes Korea the largest distributer in the world. Since the interests in alternative medicine and healthy food is increasing globally, the consumer market of ginseng with many features and the processed products are expected to expand continuously.

As a result of overemphasizing the goods sector in trade structure, Korea does not meet properly the global trend which has the key role of 'trade in services' as the service economy have been expanded. Hereafter, it is easily forecasted that trade in services will be one of the main factors for Korea's competitiveness and engine of growth. Nevertheless, because Korea does not equip the concreteness of governance for trade in services, it is possible that the efficiency deterioration of trade volume, confusion of Korea's trade policy, conflict among trading countries, and discordance between the interested parties may be occurred. This paper analyzes the governance system of Korea for trade in services in order to enhance the competitiveness reflecting the importance of trade in services and to draw some strategies for remodeling the service governance system. It is expected to raise the efficiency of Korea's trade policy by constructing the systematic governance for trade in services, and to remove lots of latent risks during global transactions by improving the imbalance between manufacturing and service part for the development of trade in services in Korea. Analysis revealed itself the result that Korea is weak enough to can not identify the governance system about trade in services. Except 'Extent of Services' article of the Foreign Trade Act, Korea has not prepared the governance system for trade in services so that governance system have been scattered overly or decentralized. Problems about trade in services are not limited to enterprise's side, but extended to all the players including government agency whole, academic world and research institute. Therefore, the governance of trade in services should be strengthened and systematized by making the model law for trade in services(provisional name : Master Law for Trade in Services or Promotion Law for Trade in Services) by formatting type of fundamental law or separate legislation. If the bill legislation does not meet the conditions, the Foreign Trade Act should be totally reformed to Omnibus Trade Act concept including trade in services.

The marine cargo insurance is mainly the insurance on foreign trade commodities. The sales contract stipulates as to which of the seller or the buyer should arrange the insurance. In other words, if the sales contract is made on the C.I.F. terms, the seller has to arrange the insurance, while, in the case of F.O.B. or C.F.R. terms, the buyer has to arrange it. The F.O.B. or C.F.R. terms means that the seller has to take out an insurance for himself until the cargo being loaded onboard the overseas vessel at the port of shipment in export country. But our country has not reasonable insurance to cover seller's risk, because it hasn't yet implemented the insurance. In respect of a cargo exported from Korea on F.O.B. or C.F.R. terms, the F.O.B. insurance covers comprehensively the inland transit and storage until the cargo being loaded onboard the overseas vessel at the port of shipment in Korea with a certain limitation of a insurance period. The goal of this study is to analyze the development propriety of F.O.B. Insurance. This could be done through analyzing the volume and analyzing the proportion of F.O.B. or C.F.R. terms for export. It is supposed that the potential demands of F.O.B. insurance are sufficient in our country for developing the F.O.B. insurance. At this point of time, the positive development of F.O.B. insurance for export is inevitable from the viewpoint of present situation of trading circles.

The International Chamber of Commerce published the millennium edition of its standard trade definitions, Incoterms 2000. Incoterms are a basic reference for sales contracts, in constant daily use throughout the world. The new version will make it easier for traders to do business in the new century, despite the growing volume and complexity of international transactions. Since Incoterms were first published in 1936, they have been updated six times. They precisely define the responsibilities of buyer and seller and are recognized as the international standard by customs authorities and courts in all the main trading nations. It is important for traders to incorporate the correct Incoterms into their international contracts to avoid unnecessary legal problems. Courts may otherwise interpret trade terms according to often widely divergent national laws and unless the use of Incoterms is specified, expensive legal disputes can arise. Division of costs is a most important element in every contract of sale. The parties must know not only who does what but also how costs resulting therefrom should be divided between them. In most cases the fact that a party must do something means that he must also bear the resulting costs, unless otherwise agreed. But there are many exceptions to this principle and uncertainties arise, particularly with respect to services performed by other parties. Also, difficulties arise with respect to the division of costs whenever additional costs are caused by unexpected events, such as hindrances causing a ship to deviate or to remain in a seaport longer than expected. The main principle of the division of costs is clear enough: the seller has to pay costs necessary for the goods to reach the agreed point of delivery, and the buyer has to pay any further costs after that point. But as noted, it is not always easy to implement this principle in practice, since the detailed distribution of functions under the various trade terms is not and cannot be fully defined in Incoterms. Instead, failing precise stipulations in the contract of sale, guidance must be sought from other criteria such as commercial practices used earlier by the same parties or the custom of trade.

In this paper, we develop a portfolio selection model that can be used to invest in markets with margin requirements such as the foreign exchange market. An investment algorithm to implement the proposed portfolio selection model based on objective historical data is also presented. We further conduct empirical analysis on the performance of a hypothetical investment in the foreign exchange market, using the proposed portfolio selection model and investment algorithm. Using 7 currency pairs that recorded the highest trading volume in the foreign exchange market during the most recent 10 years, we compare the performance of 1) the Dollar Index, 2) a 1/N Portfolio which equally allocates capital to all N assets considered for investment, and 3) a hypothetical investment portfolio selected and managed according to the portfolio selection model and investment algorithm proposed in this paper. Performance is compared in terms of accumulated returns and Sharpe ratios for the 10-year period from January 2003 to December 2012. The results show that the hypothetical investment portfolio outperforms both benchmarks, with superior performance especially during the period following financial crisis. Overall, this paper suggests that a mathematical approach for selecting and managing an optimal investment portfolio based on objective data can achieve outstanding performance in the foreign exchange market.

This study examines the reason of a staggering trade deficit on the Korean agro-food industry. To achieve the goal of the study, this study suggests the policy implication for enlargement a trade deficit with foreign exchange rate. Despite the majority of grain importer does realize that there is a huge affection for price volatility on the business result, they are more likely to take flat pricing through the physical market to avoid risk of price volatility with exchange rate. Also the analysis of external and internal environments around the Korean agro-food export & import are conducted, particularly with the analysis of trade volume and food price affecting the export & import. Results from a survey show that the common factor to the effective use of overseas agricultural and foreign currency futures trading for grain traders in Korea.
