The possibility of by-products utilization in a sausage formulation was studied using Linear Programming. Among constraints groups (1: moisture and meat content, 1 + heart, 1 + organ, 1 + head, 1 + heart + backfat, 1 + heart + organ, 1 + heart + head, 1 + heart + head + backfat), the group in which moisture and meat content, and the use of heart and organ were considered appeared to give the least-cost formulation. The groups where the use of backfat was considered resulted in higher-cost formulations. However, if the formulation contains bindery and extenders such as vegetable proteins or milk proteins which are not limited in use antler the Korean regulation, the result would be different from that obtained here.

This paper examines the effect of unique underwriter lockup on the initial returns of an initial public offering (IPO) in the Korean Securities Dealers Automated Quotation (KOSDAQ). Underwriter lockup induces underwriters to underprice IPOs and stabilize aftermarket prices. The inducement is explored with respects to the mixtures of distributions of the initial returns consistent with underpricing and stabilization. Whether the inducement is meaningful when other factors are controlled is also explored. These explorations provide evidence that underwriter lockup leads to more positive average initial returns in the three aftermarket months.

본고(本稿) 1981~92년의 부당한 공동행위(共同行爲) 및 사업자단체금지행위(事業者團體禁止行爲) 심결례(審決例)들을 통해 우리나라 사업자들의 담합(談合)패턴과 특징(特徵)을 살펴보고 이를 바탕으로 담합규제법제(談合規制法制)와 그 운용상(運用上)의 문제(問題)들을 검토하여 담합규제(談合規制)의 실효성(實效性) 제고(提高)를 위한 경쟁정책적(競爭政策的) 대안(代案)들을 제시하고 있다. 우리의 담합규제법제(談合規制法制)와 법시행방법(法施行方法)은 은밀하고 지속적인 담합(談合)보다는 담합(談合)의 직접적 증거를 남길 가망이 많은 명시적(明示的) 공모행위(共謀行爲)의 적발(摘發)로 기울어져 있는 것으로 보인다. 사실, 담합사건(談合事件)들이 경쟁적(競爭的) 시장(市場)에 편재(偏在)되어 있고 사업자간(事業者間) 및 사업자단체(事業者團體) 공동행위(共同行爲)의 평균공모기간(平均共謀期間)이 각각 8개월과 10.7개월에 지나지 않는다는 것은 적발 시정조치된 행위(行爲)가 주로 담합(談合)의 시도(試圖)였음을 시사하는 것이다. 또한 가격고정공모(價格固定共謀)의 평균가격인상율(平均價格引上率)이 18%임을 감안할 때 담합실행기간(談合實行期間) 매출액(賣出額)의 1%라는 현재의 최고(最高) 과징금액(課徵金額)은 부당이득환수(不當利得還收)나 행정제재(行政制裁)의 어떤 측면에서도 그 실효성(實效性)이 극히 의심스러운 적은 금액이며, 거의 모든 위법행위(違法行爲)에 대하여 시정조치(是正措置)만이 취해지고 담합사업자(談合事業者)들에게 과징금(課徵金)이나 형사벌(刑事罰)이 부과되는 경우도 극히 드물어 담합억지효과(談合抑止效果)가 의문시되고 있다. 담합규제(談合規制)의 실효성(實效性) 제고(提高)를 위해서는 경쟁(競爭)의 실질적(實質的) 제한성(制限性)이 아니라 경쟁제한(競爭制限)의 부당성(不當性)을 위법성(違法性) 판단기준으로 하여 가격고정(價格固定), 입찰조작(入札操作), 시장분할(市場分割) 등 '적나라한' 담합(談合)에 대한 당연위법원칙(當然違法原則)을 확립하고, 과징금(課徵金)을 담합기간(談合期間) 매출액(賣出額)의 20% 정도로 상향조정(上向調整)하여 담합(談合)에 대한 핵심적 제재수단(制裁手段)으로 활용하여야 한다, 또한 담합(談合)의 적발(摘發) 입증노력(立證努力)에 경제적(經濟的) 분석(分析)과 증거(證據)를 이용하고, 특히 입찰조작(入札操作)의 감시(監視) 적발체제(摘發體制)를 확립하여 공공조달분야(公共調達分野)에 대한 경쟁정책(競爭政策)을 강화해야 하며, 묵시적(默示的) 담합(談合)을 가능케 하면서도 합의(合意)로 간주될 수 없는 담합촉진(談合促進) 기도행위(企圖行爲)를 금지할 법적(法的) 근거(根據)를 마련해야 할 것이다.

Using high-frequency data for 2 years, this study investigates intraday lead-lag relationship between stock index and stock index futures markets in Korea and China. We found that there are some differences in price discovery and volatility transmission between Korea and China after the stock index futures markets was introduced. Following Stoll-Whaley(1990) and Chan(1992), the multiple regression is estimated to examine the lead-lag patterns between the two markets by Newey-West's(1987) heteroskedasticity and autocorrelation consistent covariance matrix(HAC matrix). Empirical results of KOSPI 200 shows that the futures market leads the cash market and weak evidence that the cash market leads the futures market. New market information disseminates in the futures market before the stock market with index arbitrageurs then stepping in quickly to bring the cost-of-carry relation back into alignment. The regression tests for the conditional volatility which is estimated using EGARCH model do not show that there is a clear pattern of the futures market leading the stock market in terms of the volatility even though controlling nonsynchronous trading effects. This implies that information in price innovations that originate in the futures market is transmitted to the volatility of the cash market. Empirical results of CSI 300 shows that the cash market is found to play a more dominant role in the price discovery process after the Chinese index started a sharp decline immediately after the stock index futures were introduced. The new stock index futures markets does not function well in its price discovery performance at its infancy stage, apparently due to high barriers to entry into this emerging futures markets. Based on EGAECH model, the results uncover strong bi-directional dependence in the intraday volatility of both markets.

This study was tried to calculate the stumpage value using GIS technique. Before calculating this price the feasible areas to cut were divided from all forests. The stumpage value per $m^3$ was calculated by the method of calculating back from the market price, according to the working volume of logging unit and clearing a felling area using GIS. The distribution of the stumpage value for the coniferous stands was estimated from minimum 10,000 won to maximum 50,000 won, and for the deciduous stands the stumpage value was distributed from minimum 20,000 won to maximum 40,000 won. The total estimated selling price for the cutting available area (197.3ha) among this study area(250ha) except the cutting limited area was about 1.13 billions won. And the estimated selling price for the korean white pine stands was about 650 millions won, occupied 57% among the total selling price, and for the deciduous stands showed 383 millions won, occupied 34% of the total price, and for the japanese larch was 9.69 millions won, occupied 9% of the total price. But the rigida pine stands showed only 1.22 millions won.

This paper compares the price strategies of Korean internet retailers against those of Korean traditional retailers in regard to books, CD\\`s, cosmetics, softwares, PC and peripherals, and electronic home appliances. The data shows that the average prices of books, CD\\`s, and cosmetics are cheaper in the internet market than in the traditional market when there is a large purchase. However, when there is a small purchase, the average prices of books and CD\\`s are more expensive in the internet market than in the traditional market. In other cases, the difference of the average prices in the two markets was negligible. When there is a large purchase, the dispersion of prices of books is smaller in the internee market than in the traditional market. In other cases, the dispersion of prices is smaller in the internet market than in the traditional market, but the difference was negligible to be statistically significant. The findings imply that internet retailers generally pursue a specialization strategy against traditional retailers by factors other than prices. Internee retailers seem to pursue price competition against traditional retailers only for large purchases in some cheap commodity industries. It is also found that the internet shopping-malls managed or owned by existing traditional retailers or manufactures are rare and are operated dependently on existing distribution channels. The findings also imply that the Internet market begins to be established only in some cheap commodity industries and the Internet market has yet to be generally established in Korea.

This study empirically analyzed the determinants of the assessment ratio (hereinafter 'AR') based on a total of 2,129 sales cases of forests in Gwangju, Gyeonggi-do. The main findings of this study through multiple regression analysis are summarized as follows. First, this study shows that regional characteristics have significantly different effects on the AR of forest land prices. Specifically, there was a significant difference in the AR depending on the location of the parcel by sub-region and the ratio of residential area, and the higher the number of development plans in progress, the more likely the officially assessed land price will be formed close to the sale price. Second, this study analyzed that location characteristics such as the proximity of the inner and outer center of the jurisdiction and traffic accessibility had a significant influence on the determination of the AR. Third, this study identified significant differences in AR depending on detailed factors such as planning management areas, production management areas, conservation areas for mountain, conservation areas for nature, and restricted development areas as land use and regulatory characteristics of forest lands. Fourth, this study found that land characteristics are a significant factor influencing the AR as an individual factor in forest land.

Water is an essential element required for the survival of 6 billion human beings around the world, and it has limited mobility. The importance of water industry has grown considerably, as its forecasted market size is expected to increase from $336 billion in 2007 to $865 billion in 2025, respectively. In 2003, the domestic water market was estimated to be worth 11 trillion won. However, according to the estimates of this research, the result above was overestimated by 2 trillion won. The economic ripple effects of newly defined water industry based on the input-output data from 2000 to 2008 were trivial, as the price effects of water industry was considerably minor at only 0.12%. To successfully implement policies to enhance the water industry, the market price mechanism must operate and function properly. Nevertheless, the impact of water's market prices on the economy upon application is projected to be trivial.

우리나라에서는 그 동안 유상증자(有償增資)시 주주배정(株主配定)(right offer)방식에 의하고 기업공개시의 발행가격도 일률적으로 산정(算定)되어 증권인수(證券引受)에 따른 인수기관(引受機關)(underwriter)의 역할이 제한되어 왔으나 앞으로는 증권발행방식이 다양화되어 발행가격의 결정을 포함한 인수기관의 역할이 강조될 것이다. 대부분 총액인수(總額引受)(firm commitment underwriting)방식을 택하는 미국자본시장에서 인수기관을 선정하고 발행조건들을 결정하는 방법에는 투자은행과의 협의(協議)(negotiation)에 의하는 방식과 비공개경쟁입찰(非公開競爭入札)(sealed bidding)에 의하는 방식이 있는데 많은 기업들은 상대적으로 비용이 많이 드는 협의발행을 선택한다. 본 연구에서는 이에 대한 가설들을 뉴욕증권거래소나 아메리칸증권거래소에서 거래되는 공익기업의 신주발행자료를 통해 실증 검정했다. 인수 스프레드(underwriting spread)는 발행금액에 관계없이 협의발행(協議發行)이 경쟁발행(競爭發行)보다 평균적으로 1.16% 높았으며 발행비용(發行費用)도 협의발행이 유의적인 수준에서 0.341% 정도 높았다. 비대칭정보하에서 신호균형(信號均衡)(signaling equilibrium)으로 설명할 수 없지만 협의발행에 의한 통합균형(統合均衡)(pooling equilibrium)의 가능성은 배제하지 못했다. 주식발행 발표일(發表日)(announcement date)을 전후해 인수방식에 따른 주가변동의 차이를 분석한 결과 대리인가설(代理人假說)은 부분적으로 지지했다. 발행일(發行日)(offering date)을 전후한 주가변동에 의하면 인수기관의 사전매각노력(事前賣却努力)이 협의발행하에서 더 높았으나 발행일 직후의 주가회복은 보이지 않아 인수방식에 따른 가격안정화(價格安定化) 노력의 차이는 없었다. 발행기업들간의 주가차별화의 정도를 분석한 결과 협의발행에서 인회활동(認淮活動) (certification effects)을 더 잘 할 수 있다는 사실을 지지하지 못했다.
