기업간 전자상거래에서 조합경매(combinational auction)에 대한 관심이 증가함에 따라 다양한 조합경매 유형이 제시되고 있다. 조합경매의 실용성에 대한 잠재적 중요성을 고려할 때, 다양한 조합경매모델을 지원할 수 있는 통합적이고 체계적인 설계방법이 필요하다. 조합경매 설계에 대한 기존 연구들은 조합경매에 관한 일부 설계요소들에 대해서만 제시하였으며, 부분적인 측면에서 연구가 진행되어 전체적인 관점에서의 설계체계가 제시되지 않았다. 이에 본 연구에서는 조합경매모형에 대한 설계의 토대가 될 수 있는 체계적인 틀을 제시하고자 한다. 설계단계는 크게 아키텍처, 프로토콜, 거래전략 설계 과정으로 이루어진다. 설계과정에서 아키텍처 유형과 프로세스 유형을 분류하고 이들의 조합으로 나타나는 메커니즘 유형을 분류하여 조합경매 모형에 대한 분류체계를 제시하였다. 또한, 거래전략 설계 단계에서는, 거래 당사자들의 다양한 전략을 반영하여 최적의 거래대상을 선정하는 최적화 모형에 기반한 효과적인 조합경매모형 설계방법을 제안하였다. 마지막으로, 본 방법론에 기반하여 새로운 조합경매 모형인 다자간 일반 조합경매 시장에 대한 설계과정을 예시함으로써, 본 방법론의 적용 가능성을 제시하였다.

본 연구는 신뢰성 기반의 상가건물 권리분석 프로그램을 개발하기 위한 연구로서 기존의 권리분석 프로그램에서 진일보하여 보다 현실에 부합한 분석방법을 제시하고 있다. 기존 연구는 단순히 직전 3개월에서 1년 사이의 경매낙찰가율과 경매낙찰가를 예상하고 이를 토대로 권리분석을 수행하였다. 그러나 본 연구에서는 상권분석시스템에서 제공하는 상권활성화 정도를 권리분석프로그램에 입력변수로 활용하여 경매에서의 낙찰가를 예측하고 이를 토대로 권리분석을 수행하도록 하였다.

To get the items that a buyer wants in Internet auction. he must search for the items through several auction sites. When the bidding starts, he(the buyer) needs to connect to these auction sites frequently so that he can monitor the bid stats and re-bid. A reserve-price auction reduces the number of connections, but this limits the user's bidding strategy. Another problem is equity between the buyer and the seller. Both the buyer and the seller should profit together within proper limits. In this paper, we propose an auction agent system using a collaborative mobile agent and a brokering mechanism called MoCAAS (Mobile Collaborative Auction Agent System), which mediates between the buyer and the seller and executes bidding asynchronously and autonomously. This reduces connection costs. offers more intelligent bidding and solves the equity problem.

In this paper, we introduce a new combinatorial auction mechanism - N-Bilateral Optimized Combinatorial Auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers optimized trading for multi-suppliers and multi-purchasers in the supply chain. We design the N-BOCA system from the perspectives of architecture, protocol, and trading strategy. Under the given N-BOCA architecture and protocol, auctioneers and bidders have diverse decision strategies for winner determination. This needs flexible modeling environments. Hence, we propose an optimization modeling agent for bid and auctioneer selection. The agent has the capability to automatic model formulation for Integer Programming modeling. Finally, we show the viability of N-BOCA through prototype and experiments. The results say both higher allocation efficiency and effectiveness compared with I-to-N general combinatorial auction mechanisms.

This paper introduces the 5G spectrum auction in Germany that occurred last summer and ended overheatedly after an extraordinarily long period. We describe the context of the latest German spectrum auction and trace the participants' bidding behavior. This case details the trend of the 5G spectrum auction and the factors that affect the spectrum auction as follows: First, it is determined that investment obligations that force network installations can be a financial burden to mobile network operators (MNOs) and require a careful approach. Second, excess demands can cause auction overheating and the spectrum supply volume needs to be determined by a proper demand forecast and investment incentive. Third, 'Set-Aside' for local usage aids in developing the vertical industry; however it limits the spectrum supply for mobiles and leads to higher bidding prices. Fourth, a modified adoption of a typical spectrum auction can alleviate MNO's financial burdens to secure the broadband spectrum. Finally, competition to secure the necessary bandwidth in the situation of limited spectrum supply may delay the process of the spectrum auction, causing it overheated.

This paper Introduces an electronic auction service to be provided on Interactive TV (T-auction). This converged service is expected to much enhance the quality of the service to current online auction users through vivid visualization and live Interactive experience. Our study focuses on how the characteristics of the interactive TV-based shopping platform can affect users' attitudes towards the converged service. To develop our proposed research model, we extended the technology acceptance model and integrated it with a hedonic factor, or perceived enjoyment to reflect the dual characteristics of the converged system. We also adopted the variable of intermediary trust In the service as a critical mediating determinant for a successful commutations-mediated commerce. The research model was verified with an empirical study conducted on 970 Korean online auction users. Results show that both trust and perceived usefulness positively affect user adoption of the service. Trust had not only a direct effect on users' attitudes toward T-auction but also an indirect one by mediating the service quality, information quality, perceived enjoyment and ease of use. Meanwhile, the hedonic factor of T-auction contributes to increasing both the level of the intermediary's trust and its perceived usefulness. Users' enjoyment also was found to help form a positive attitude toward T-auction services. Theoretical and practical implications of this study for current e-auction service providers and potential t-auction service providers are also discussed.

This paper searches Internet auction sites to study consumer willingness to reuse and consumer satisfaction, along with its frequency of usage and evaluation. This study also examines the differency in the frequency of usage, the number of products purchased, consumer satisfaction and willingness to reuse, and evaluation of the auction sites according to the characteristics of consumers' socio-economic factors and the auction site itself. Determinant variables is investigated in the level of consumer satisfaction. The results of this study are as below: First, consumers used auction sites frequently, especially when they were in their 20s, intended to purchase clothes, and thought the delivery time would be short. In addition, consumers were more likely to purchase products, with low income buy first pay later, and short deliberation. Second, consumers, unemployed and in their 50s, sell-purchase among consumers were less likely to have a willingness to reuse the auction site. However, consumers with an experience to buy clothes or products with a price between 50,000 and 100,000 won were more likely to have a willingness to reuse the site. Third, consumer satisfaction with auction sites were higher among those who were females; responsible as a consumer; full of experiences; and received the product within a short period of time. Lastly, the willingness to reuse auction sites was positively related to the following type of consumers: single, employed, and responsible as a consumer.

The Federal Communications Commission (FCC), which regulates interstate and international communications in the United States, has established a plan to allocate high demand spectrum to the usage of mobile communication by inducing voluntary relinquishment from broadcasters. This plan was introduced by the National Broadband Plan as an incentive auction in 2010. The FCC suggested the Notice of Proposed Rulemaking (NPRM) in 2012 and issued Report and Order (R&O) on May 2014 regarding the overall rules of incentive auctions expected to be implemented in mid-2015. The incentive auction attracts the attention of many countries because this policy suggests a novel approach regarding the alteration of use from an inefficient usage to an efficient usage in limited spectrum resources. In this paper, we define the key issues in order for implementation of incentive auction. Since the incentive auction is a highly complicated process compared to previous allocation procedures, a careful review of the incentive auction regarding whether this spectrum policy can be introduced is required. In this paper, we describe the detailed procedure of the incentive auction and present policy considerations for the introduction of the incentive auction.

We empirically examine the impact of online auction knowledge and category-specific knowledge on the final price of online auctions. Specifically, we question how the relationship between buying and selling experiences affects the final prices of online auctions. Related to the trust between buyers and sellers, we examine the multiple interactions between a buyer-seller pairand aim to identify how these repeated transactions influence the final price. To contrast these effects with other product related factors, we focus on so called 'common value' auctions of vintage stamps on eBay, in which the ex-post value of the product is the same among participating agents’ perceived value. Online auction of stamps provides a representative setting to examine the relationship between market experience and the auction participation behavior in the common value auction, as it provides the book value of stamp as well as price variation across individual buyers with different expertise levels. Our analysis of over 3000 stamps auctions on eBay indicates a significantly high frequency of buyer-seller (pair) interactions, thus suggesting a 'relationship view' of auctions. The work validates five hypotheses derived from the existing theory in economics, marketing, and information systems. Through the common-value auction data, we find that seller's online auction experience and category-specific experience favor sellers by increasing the final price. However, buyer's online auction experience does not affect the final price, but buyer's category-specific experience favors buyers by decreasing the final price. We find that the trust between two trading parties increases the final price.
