Purpose - This study investigates the improvement of rationalization of distribution structure in Korean diamond market. It also explores the international distribution of diamond and how the distribution of Korean diamond market system was improved. This study also for providing the evaluation method in case of purchasing diamond on the consumers. Research Design, Data, and Methodology - The research investigates how international diamond distribution market has been changed since 1933 by De Beers. The international Diamond rough stone has been deregulated in supply and demand by Debeers since July, 2000, therefore, the price maintenance policy of diamond market also has been changed. In the short term, the diamond price in market has been down, whereas, in the long term, the market share of Debeers has affected the high quality of diamond price in world market. Before 1985, both G color and VVS1 clarity were used as the level of percentages in the diamond certificate of authenticity in Korea. But, after 1985, the diamond certificate of authenticity uses Diamond Grading Report. Results - Between the 1970's and 1980's, Debeers had controlled about 80 percentages of international diamond supply market. But, Debeers share in diamond market fell by 60 percentages in 2000's. Debeers supplied 31%(4390 carets) of international diamond supply and 41%(39 billion dollars) in 2003. However, Debeers shares 50% of market shares in the diamond supply market by Alosa in Russia. In Korea, the diamond grading report system has been used since 1985. But, the diamond grading report system has price bubbles and much irrational parts in grading system methods. Conclusions - 4C, the grading system of diamond, is a method for comparing and evaluating diamond objectively. Diamond is graded according to its color, cut, clarity, and carat. The price of diamond is determined based on its each item. Consumers purchase diamond for the purpose of investment and wearing. In terms of investment, it is recommended to purchase diamond with color of D grade, cut with Excellent or Very Good Cut grade, Clarity of FL or IF, and more than 3 carat. As for wearing purpose, it is highly recommended for diamond to have color of F or G grade, cut of Excellent or Very Good Cut, clarity of VS2 or SI1, and more than 1 carat Before 2000, Central Selling Organization(CSO) distributed about 80 percentages rough diamond to world market exclusively by purchase, classification, assessment, and sales. After 2000, Dbeers diamond company looses slowly market shares, while Almosa diamond company etc. in Russia are taking over world market shares more and more. Debeers market shares have been falling over the years, and the international diamond markets are gradually growing by other international diamond companies. But, there is no change in Korean diamond market after 1980's. Korean diamond distribution needs to follow international level of Diamond Grading System. By using different grading systems with different panel members, Korean diamond grading system needs to follow international perfect grading systems to grow diamond markets and maintain within top 10 diamond markets countries.

경제위기 이후 은행 등 금융기관의 기업 규모별 대출분포를 살펴보면 대규모 기업에서 중소규모 기업으로 그 비중이 이동하였음을 알 수 있다. 이러한 현상의 원인 중 하나로 경제위기 이후 진행된 금융구조 개혁으로 금융기관의 대출관행이 개선된 점을 들 수 있다. 경제위기 이후 회사채시장에서도 중요한 변화가 정착되고 있다. 경제위기 이전에는 기업 또는 그룹의 규모 자체가 회사채 조달에 있어 중요한 결정요인 중 하나였는데, 경제위기 이후 그러한 현상이 사라져가고 있는 것이다. 이는 경제위기 이전에는 소위 "대마불사"의 신화로 일반투자자들이 대규모 재벌의 회사채를 수익성과 관계없이 선호하였으나, 1999년 대우그룹 붕괴 및 2000~2001년 현대그룹 유동성 위기 등으로 그러한 불합리한 믿음이 깨지게 된 것과 밀접한 관련이 있다.

Although the main objective of Free Trade Agreements (FTA) is market integration among member countries, there are limited studies supporting this impact. Our study explores whether FTA has enhanced market integration between South Korea and its FTA partners, focusing on South Korea's fishery product import market. We investigate two research questions concerning FTA impacts: first, whether trade costs declined when South Korea imported fishery products from its FTA partners after the FTA; second, if the speed of the convergence of South Korea-its FTA partners'price differential of imported fishery products on trade costs result to occur more quickly after the FTA. To determine these outcomes, we utilize a Threshold Autoregressive Model covering the sample periods from January 2002 to April 2017. Our findings demonstrate the effects of FTA on market integration are different among FTA partners. FTA has enhanced the market integration between South Korea and Norway, Vietnam, and Spain, respectively, but not for others. Therefore, we find positive evidence of FTA on fishery import market integration between South Korea and Norway, Vietnam and Spain, respectively.

This study examines the nominal price anomaly in the Vietnamese stock market, that is, whether stocks with low nominal price outperform stocks with high nominal price. Using a sample of all 351 companies listed on the Ho Chi Minh Stock Exchange (HOSE) from June 2009 to March 2018, we confirm our hypothesis and document that cheaper stocks yield higher subsequent abnormal returns. The results are robust after controlling for various stock characteristics that have been documented to be value-relevant in prior literature, including firm size, book-to-market ratio, intermediate-term momentum, short-term reversal, skewness, market risk, idiosyncratic risk, illiquidity and extreme daily returns, using both the portfolio analysis and the Fama-MacBeth cross-sectional regression. The negative effect persists in the long term (i.e., after up to 12 months), implying a slow adjustment of stock prices to their intrinsic value. Further analysis show that the observed nominal price anomaly is mainly driven by mispricing but not a latent risk factor proxied by stock price, thus the observed anomaly reflects a mispricing but not a fundamental risk. The study highlights the irrational behaviour of investors and market inefficiency in the Vietnamese stock market and provides important implication for investors in the market.

This paper is aim to test how market orientation is related to the investment decision making. After controlling for firm-specific factors, this study finds a significantly positive relationship between market orientation and R&D expenditures, especially firms with high ratio of intangible assets and low ratio of abnormal inventory assets. Under conditions of low quality of earnings, the negative relation between market orientation and R&D expenditures is enhanced in electronic related industries. This indicates that the relation between market orientation and R&D expenditures may exhibit more reasonable patterns for investment decision of firms in technology driven business environment.

In 1967, cheese was first produced with small scale of mozzarella cheese in Korea. The processed cheese market was highly grown after putting on the market of sliced cheese in the late 1980's, and the various products that complied with well-being trends such as organic and high functional cheese have been produced in the 2000's. The natural cheese opens up a new domestic market after producing camembert and brie cheese in the end of 2004. At present. the cheese market is expanded with differentiated products such as high value added and high functional cheese. The size of domestic cheese market remains about 200 billion won, but it is expected to go over a trillion won on account of growing preference of natural cheese with well-being trends. To promote domestic cheese industry, differentiation policy of raw milk price for cheese, diversification of cheese products, financial support to farm-made cheese industry and automation and processing development to improve productivity should be taken into account in the future in Korea.

글로벌 경제위기이후 중국은 세계경제의 두 축의 하나로 부상하였으며, 한국경제에 가장 큰 영향을 미치는 국가로 자리매김 하고 있다. 그럼에도 불구하고, 현재까지 한국에서는 중국의 금융시장 특히는 자본시장에 관한 연구가 매우 적은 실정이다. 본 연구는 중국 심천증권거래소에 출범한 창업판시장을 살펴보고, 중국 중소벤처기업의 상장전후 경영성과를 비교분석하였다. 기술혁신 벤처기업과 고성장형 중소기업들의 자금조달을 목적으로 하는 중국 창업판시장에서 기업의 상장요건은 상해와 심천 증권거래소의 주시장보다 완화되어 있으며, 상장절차도 간소화되어 있다. 따라서 중국의 많은 기업들이 상장하고자 하며, 상장 경쟁도 매우 치열하다. 그리고 창업판시장에 최초로 상장한 36개 기업의 상장 전후의 경영성과를 살펴본 결과, 자기자본 순이익률 부채비율 영업이익증가율 등 3개 지표는 모두 크게 하락하였으며, 거의 모든 기업에서 이런 현상이 나타났다. 즉, 중국 창업판시장에 상장한 중소벤처기업들의 수익성과 성장성은 상장후 급속하게 하락하였으며, 많은 자금조달로 인하여 안정성만이 개선되어 있었다. 나아가 이러한 현상은 중소벤처기업들이 상장을 위하여 상장전 경영성과를 과대 포장한데서 기인한 것으로 분석되었다. 따라서 중국 증권감독관리위원회는 향후 상장기업에 대한 회계심사기준과 심사제도를 강화하여야 할 것이며, 분식회계기업에 대해서는 엄중한 제재조치를 실시하여 건전한 자본시장 풍토를 정착시켜야 할 것이다.

The study examines the behavior of stock prices after large price changes. It further examines the effect of firm size on stock returns, and the presence of the disposition effect. The study employs the event study methodology using daily price data from Pakistan Stock Exchange (PSX) for the period January 2001 to July 2012. Furthermore, to examine the factors that explain stock price behavior after large price movements, the study employs a two-way fixed-effect model that allows for the analysis of unobservable company and time fixed effects that explain market reversals or continuation. The findings suggest that winners perform better than losers after experiencing large price shocks thus showing a momentum behavior. In addition, the winners remain the winner, while the losers continue to lose more. This suggests that most of the investors in PSX behave rationally. Further, the study finds no evidence of disposition effect in PSX. The investors underreact to new information and the prices continue to move in the direction of initial change. The pooled regression estimates show that firm size is positively related to post-event abnormal returns while the fixed-effect model reveals the presence of unobservable firm-specific and time-specific effects that account for price continuation.

After the launch of PCS in 1997, price competition between five mobile carriers was so severe that the Korean mobile telephony market achieved a remarkable subscriber base growth. But in that optimal pricing behavior depends on how each fm is likely to react to other frims'choice of price, it is very interesting to analyze competitive pricing behavior and understand market structure in terms of pricing competitiveness in the Korean mobile telecommunications market. In this paper, we use structural econometric models in New Empirical Industrial Organization (NEIO) framework. But previously used models in this framework generally assume that market size is fixed and that all firms maximize their profits. To fit in with the Korean mobile telephony market, we derive various models in using NML market share model under the assumptions that market size varies with industry's total attractions and that firms maximize their market share. In this paper, we find that the model under market share maximization with the assumption that market size varies with total attraction shows the best fitting results.
