Agent-mediated electronic markets have been a grow-ing area of agent research and developmen tin recent year. There exist a lot of e-commerce sites on the In-ternet(e.g. Priceline, com, Amazon, com etc). These e-commerce site have proposed new business models for effective and efficient commerce activity. Intelli-gent agents have been studied very widely in the field of artificial intelligence, For purpose of this paper, an agent can act autonomously and collaboratively in a network environment on behalf of its users. It is hard for people to effectively and efficiently monitor, buy, and sell at multiple e-commerce sites. If we intro-duce agent technologies into e-commerce systems, we can expect to further enhance the intelligence of their support. In this paper, we propose a new coopera-tion mechanism among seller agents based on exchang-ing their goods in our agent-mediated electronic market system. G-Commerce. On G-Commerce, seller agents and buyer agents negotiate with each other. In our model, seller agents cooperatively negotiate in order to effectively sell goods in stock. Buyer agents coopera-tively form coalitions in order to buy goods based an discount proices. Seller agent's negotiation goods. Our current experiments show that exchanging mechanism enables seller agents to effectively sell goods in stock. Also, we present the Pareto optimality of our exchang-ing mechanism.

e-마켓플레이스는 구매자들이 보다 신뢰할 수 있는 판매자와 거래할 수 있도록 평판 시스템(Reputation system)을 구축하여 예비 소비자들에게 판매자의 평판을 제공한다. 판매자의 평판은 소비자의 평점을 기반으로 산출되는데 이 때 소비자의 평가 요소로는 판매자의 행동에 대한 평가와 상품에 대한 평가가 있다. 기존의 평판 계산 방안들은 구매자의 평점이 두 가지의 평가가 혼합된 점수라는 것을 인지하지 못한 채로 판매자의 평판을 산출한다. 본 논문에서는 소비자 평점을 판매자 점수와 상품 점수로 분리한 후 오직 '판매자의 점수'만을 이용하는 평판 계산 방안을 제안한다. 제안하는 방안은 판매자의 점수만을 이용하여 판매자의 능력에 대한 평판만을 제공하는 방안으로 예비 소비자들이 빠른 배송과 친절한 서비스를 제공하는 판매자를 선택할 수 있도록 돕는다. 실험에서는 실제 e-마켓 플레이스의 현실성을 반영한 시뮬레이션 방안을 제안한다. 생성된 시뮬레이션 데이터를 기반으로 진행하는 실험을 통해 제안하는 방법의 우수성을 입증한다.

CISG provides the place of payment at the Article 57 which if the buyer is not bound to pay the price at any other particular place, he must pay it to the seller (a) at the seller's p lace of business or (b) if the payment is to be made against the handing over of the goods or of documents, at the place where the handing over takes place. When the parties have agreed that payment is to be made against the handing over of the goods or of documents, the place where this is to happen according to the contract or CISG is the place of payment. When the parties have not agreed to this, the place of payment is the seller's place of payment. The buyer does not send the money to seller's office, but pays it to the seller's bank account. Where payment is effected by a L/C, such operations shall be governed by UCP and collection of money governed by URC. The payment at the seller's place of payment affects the rate of interest, currency of money and jurisdiction which is interpreted by Brussel convention and Lugano convention. The principle on which the CISG is based, characterizes the obligation of payment as an obligation to be performed at the creditor's place of business. This principle affects the place of damage claims payable to be at the creditor's that place. Payment at the place of business is required, but not inside the place itself.

Risk of loss is a term used in the law of contracts to determine which party should bear the burden of risk for damage occurring to goods after the sale has been completed, but before delivery has occurred. Under the Uniform Commercial Code (UCC), there are four risk of loss rules, in order of application. First, it is agreement that is the agreement of the parties controls. Second, the breaching party is liable for any uninsured loss even though breach is unrelated to the problem. Hence, if the breach is the time of delivery, and the goods show up broken, then the breaching rule applies risk of loss on the seller. Third, the delivery by common carrier other than by seller is necessary: Risk of loss shifts from seller to buyer at the time that seller completes its delivery obligations; If it is a destination contract, then risk of loss is on the seller; If it is a delivery contract, then the risk of loss is on the buyer. Fourth, if the seller is a merchant, then the risk of loss shifts to the buyer upon buyer's receipt of the goods. If the buyer never takes possession, then the seller still has the risk of loss. This paper discusses problems of risk of loss under the American law. Specifically, this paper focuses on the interpretation of UCC sections and analysis of various cases. By comparing, also, UCC and Korean law, the paper proposes some implications of risk of loss issues for Korean law.

본 연구는 2000년부터 2007년 말까지 일본의 상장제조기업 중에서 자산을 매각한 기업과 그것을 구입한 기업을 대상으로 자산매각의 경제적 성과를 측정하고 이에 영향을 미치는 요인을 분석하였다. 사건연구 방법에 의한 분석결과, 자산매각 공시전후의 단기간에는 매각기업의 경우 양(+)의 초과 수익률을 얻었지만, 매수기업의 주주의 손익에는 변화가 없었다. 하지만, 같은 자산을 매각한 기업과 매수한 기업만을 분석한 결과 매각기업과 매수기업의 초과수익률은 유의한 양(+)이며 합동 초과수익률 또한 유의한 양(+)으로 나타났으므로 자산매각은 기업가치를 증가시키는 거래라고 결론지을 수 있다. 기업성과와 재무적 특성과의 횡단면회귀분석의 결과를 보면, 매각기업의 공시효과와 ROA, 부채는 유의적인 양(+)의 관계를 갖고 있고, 매수기업의 공시효과는 부채, 외국인 주주비율과 유의적인 양(+)을 보였지만 기업규모와는 유의적인 양(-)의 관계를 나타냈다. 그 외의 토빈의 q와 임원주주비율, 은행주주비율은 중요한 요인이 되지 못하고 있다.

In international sales of goods, the buyer must pay the price for the goods as required by the contract and CISG, The buyer's this obligation includes taking such steps and complying with such formalities as may be required under the contract, which includes providing the seller with relevant letter of credit through the issuing bank. Where the parties have not stipulated the time limit within which the credit should be opened, but there is an agreed date or period for shipment, the time limit for the L/C opening should be calculated back from the agreed date of shipment or the first date of shipment, while, in addition, the buyer should open the L/C sufficiently earlier than the shipment date in order for the seller to be able to know the L/C's opening before beginning to ship the goods. The L/C provided the buyer should conform to the contract of sale. Therefore, for example, when an unconfirmed L/C is provided violating the agreement or the L/C opened states that, under a FOB contract, a "freght prepaid" bill of lading shall be presented as a required document of the L/C, the buyer has failed to perform his obligation. If the buyer fails to perform his obligations to provide the letter of credit, the seller may require the buyer to perform that obligation; may fix an additional period of time of reasonable length for performance of the obligation; or, the seller may declare the contract avoided, if the failure amounts to a fundamental breach of contract, or if the buyer does not, within the additional period of time fixed by the seller, perform the obligation; and the seller claim damages. However, when a relevant L/C has been issued for the seller, as a rule, he cannot ask directly for the buyer to pay the price before avail himself of the L/C first.

This study has been focused on the revisions and characteristics of the 7 non-maritime trade terms(EXW, FCA, CPT, CIP, DAF, DDU and DDP) in Incoterms 2000. Main characteristics are as follows: First, the use of different expressions intended to convey the same meaning has been avoided and the same expressions as appear CISG have been used. Second, the content of preamble in each trade terms has been shortened and definitedly. Third, if the parties are going to use variants of trade terms in Incotrems 2000, the meanings should be made clear by adding explicit wording in the contract of sale. Main revisions of the 7 trade terms are as belows: First, Incoterms 2000 has emphasized that in EXW, the seller delivers when he places the goods at the disposal of the buyer at the seller's premises or another named place(i.e. works, factory, warehouse, etc.) not cleared for export and not loaded on any collecting vehicle. Second, in FCA, delivery is completed; a) If delivery occurs at the seller's premises, the seller is responsible for loading. b) If delivery occurs at any other place, the seller is not responsible for unloading. Third, in CPT and CIP, all costs and charges relating to the goods whilst in transit until their arrival at the agreed place of destination, unloading costs and all duties, taxes and other charges as well as the costs of carrying out customs formalities payable upon import of the goods and for their transit through any country are linked with the content under the contract of carriage. Fourth, Incoterms 2000 has emphasized that in DAF, the seller delivers when the goods are placed at the disposal of the buyer on the arriving means of transport not unloaded, cleared for export, but not cleared for import at the named point and place at the frontier, but before the customs border of the adjoining country. Fifth, Incoterms 2000 has emphasized that in DDU, the seller delivers the goods to the buyer, not cleared for import(in DDP, cleared for import), and not unloaded from any arriving means of transport at the named place of destination. Sixth, if the parties do not intend to deliver the goods across the ship's rail, FCA, CPT and CIP instead of FOB, CFR and CIF should be used.

This study describes the retention of title under UCC. UCC ${\S}$ 2-401 prescribes that any retention or reservation by the seller of the title (property) in goods shipped or delivered to the buyer is limited in effect to a reservation of a security interest. It means that the retention of title generates a security interest in the same way like a charge. To be effective, a security interest must be attached or perfected. Once attachment occurs, a security interest is enforceable against the buyer. Once a security interest is perfected, a security interest is enforceable against third parties. Under UCC, a simple retention of title clause is valid as long as it is incorporated into the contract of sale. If the seller acquires a perfected security interest, he as a secured party can enjoy a priority against other creditors. But if a security interest is not perfected but PMSI is afforded, the seller has a special priority. Secondly, under UCC ${\S}$ 9-335 and 9-336, if a security interest under an enlarged retention of title clause is perfected, the seller as the secured party has a valid security interest in the product or mass into which his goods have been mixed or commingled. But in terms of assession of goods, as the seller has a security interest only in his goods, if the seller wants to enlarge his security interest in the whole, a security agreement should cover its intention. Thirdly, under UCC ${\S}$ 9-315, a security interest in proceeds of subsale of goods supplied by the seller is a perfected security interest if the security interest in the original collateral was perfected. But if the proceeds are cash proceeds, it should be identifiable from other funds of the buyer.

Purpose: This study examines the effect of full information disclosure on seller profit when there exists information asymmetry between sellers and buyers, focusing on the risk averseness of buyers. By investigating the interaction between product quality and perceived risk through online sales data, we attempt to figure out the incentive structure of full information disclosure specifically when buyers are risk-averse, so that we can suggest more feasible information disclosure strategy to sellers. Research design, data and methodology: Our empirical model analyzes the sales data of collectible goods from a major online seller using Poisson regression. In our model, we have specifically considered risk-averseness of buyers by estimating the interaction effect between the product quality and perceived risk on seller profit, aiming for a more precise empirical analysis on sellers' incentive structure of full disclosure. Results: Our empirical analysis strongly supports the effect of interaction between product quality and perceived risk, showing that the incentive for full disclosure is much stronger when product quality is higher, and vice versa. Therefore, sellers are strongly encouraged to voluntarily reveal product weaknesses when their product quality is higher than average, while it is more profitable to hide any product defects when quality claim is lower than average. Conclusions: This study supports the related literature by confirming economic incentives for full disclosure, and also supplements and strengthens previous studies by presenting that the effect of interaction between product quality and perceived risk strongly affects seller profit. Our unique finding supports both mandatory disclosure and voluntary disclosure arguments and presents practical implications to marketing managers by suggesting that seller's incentive for revealing weaknesses depends on the level of seller's product quality.
