The economics of big data knowledge, especially cloud computing and statistical data of consumer preferences, has attracted increasing academic and industry practitioners' attention. Firms nowadays require purchasing not only external private patent knowledge from other firms, but also proprietary big data knowledge to support their new product development. Extant research investigates pricing strategies of external private patent knowledge and proprietary big data knowledge separately. Yet, a comprehensive investigation of pricing strategies of these two types of knowledge is in pressing need. This research constructs an overarching pricing model of external private patent knowledge and proprietary big data knowledge through the lens of firm profitability as a knowledge transaction recipient. The proposed model can help those firms who purchase external knowledge choose the optimal knowledge structure and pricing strategies of two types of knowledge, and provide theoretical and methodological guidance for knowledge transaction recipient firms to negotiate with knowledge providers.

Pricing information services, where congestion can threaten the efficient operation of information systems, has been studied in economics and information systems literature, Recent explosion of the Internet ana proliferation of multimedia content over the Internet have rekindled the research interest in designing pricing schedules for differentiated information services, In order for the information system to effectively serve users having heterogeneous needs, pricing rules for discriminated services should be considered. At the same time, when individual users' interest does not align with that of the organization that individual users belong to, organization-wide pricing policy should be devised to improve the value of the services rendered by the system. This paper, using a priority queuing model, addresses the need for such on incentive-compatible pricing for different information services.

The quality of Internet services such as VOD and Web storage services deteriorates as the number of users increases beyond a certain point. However, most of the pricing mechanisms in research as well as those in practice do not reflect such situations (i.e., congestion). The purpose of this paper is to show that different types of pricing mechanisms are required and to model such situations using game theory. We extend Fishburn & Odlyzko(1999) model, in which the service quality is the same for the different pricing schemes, to reflect the situations where the service quality is different between the different pricing schemes due to congestion.

국내의 초고속인터넷서비스의 요금제는 정액요금제로 초기 인터넷서비스의 이용활성화에 크게 기여하였다. 하지만 가입자가 920만을 넘어서면서 포화점에 이르러 시장성숙기에 접어들면서 소량이용자의 대량이용자의 요금보조, 대량이용자의 인터넷 과용으로 인한 네트워크자원배분의 비효율성 등 정액요금제의 문제점들이 노출되기 시작하였다. 이에 효율적인 요금체계의 모색이 요구되어지는 바 종량형 요금제를 도입ㆍ시행하고 있는 호주, 벨기에, 오스트리아 둥의 초고속인터넷서비스 요금체제 및 전략을 고찰함으로써 국내 초고속인터넷서비스의 요금전략에 시사점을 도출하고자 한다.

In this paper, we compare the market performances under circuit pricing whereby users are charged based on their length of usage time and under packet pricing whereby users are charged based on the amount of information received. We show that, if packet pricing is introduced, the market price rises contrary to the government's expectation but that the overall social welfare is unambiguously increased because packet pricing reflects the social cost properly while circuit pricing does not. Also, we show that, if delivery of multi-media files requires a much higher speed, a move to packet pricing lowers the price of multi-media transmission, thereby increasing the usage of multimedia data in the absence of congestion, which may not be the case in the presence of congestion.

네트워크 서비스의 요금제는 경제적 효율성과 더불어 네트워크의 혼잡 제어라는 목적도 가지고 있다. 사용자들에 의해 공유되는 링크를 기반으로 네트워크 서비스를 제공하는 독점 공급자는 링크의 대역폭 제약 하에서 수익을 극대화하면서 사용자가 요구한 대역폭을 보장할 수 있는 요금제를 필요로 한다. 이 경우 비선형 요금제는 서비스 제공자의 목적과 사용자들의 다양한 요구를 만족시킬 수 있는 효율적인 요금제이다. 본 연구에서는 대역폭을 제공하는 네트워크 서비스에서 공유 링크의 대역폭 제약이 존재할 때 비선형 요금제가 어떻게 적용될 수 있는지 효용함수와 사용자 수요 특성의 확률 분포를 중심으로 살펴보고, 사용자의 수요 특성이 멱급수 법칙을 따르는 경우 비선형 요금제의 결과로 단위 대역폭당 가격이 일정한 선형 요금제가 나타날 수 있음을 보인다. 또한 사용자의 수요 분포에 대한 불완전한 정보를 가진 서비스 제공자가 네트워크의 혼잡도로부터 최적 요금제를 찾는 방법을 소개하고, 연구 결과에 근거하여 인터넷의 발전 방향과 인터넷 요금제의 관계를 생각한다.

Internet bid systems have been widely used recently. In those systems, the bid price is provided by the seller. When the bid price is set too high compared with the normal price, the successful bid rate can be decreased. Otherwise, when it is set too low based on inaccurate information, it can result in a successful bid with no profit at all. To resolve this problem, we propose an agent that automatically generates bid prices for sellers based on various costing methods such as the high-low point method, the scatter diagram method, and the learning curve method. Through performance experiments, we have found that the number of successful bids with appropriate profit can be increased using the bid pricing agent. Among the costing methods, the learning curve method has shown the best performance. Also, we discuss about how to design and implement the bid pricing agent.

The current advance of IT and the e-commerce triggers the wide practice of dynamic pricing in all industries although the price discrimination has been very cautiously applied in the limited areas in the past. The price discrimination which offers different prices for each customer depending on their preference and buying behaviors has recently gained attention as it could provide superior benefits to sellers. The wide adoption of price discrimination, on the other hand, is reported to face buyer resistances and complaints. Our limited understanding on the perception of price fairness, which we think is key concept in the price discrimination on the Internet-enabled transactions, motives us to investigate factors that affect the perception of price fairness. This study focuses on illusion of control and lateral customer relationship to investigate their effects on price fairness in online auction and group purchase context. By conducting laboratory experiments, our study demonstrates that customers' perception on illusion of control in price determination and advantageous lateral customer relationship significantly affect price fairness perception in both online auction and group purchase environment. The findings are expected to provide researchers and managers with useful insights to develop better pricing strategies and design effective dynamic pricing mechanisms.

In mobile communication, mobile services [MSs] (e.g., phone calls, short/multimedia messages, and Internet data) incur a cost to both mobile users (MUs) and mobile service providers (MSPs). The proposed model MobPrice consists of dynamic data pricing schemes for mobile communication in order to achieve optimal usage of MSs at minimal prices. MobPrice inspires MUs to subscribe MSs with flexibility of data sharing and intra-peer exchanges, thereby reducing overall cost. The main contributions of MobPrice are three-fold. First, it proposes a novel k-level data-pricing (kDP) scheme for MSs. Second, it extends the kDP scheme with the notion of service-sharing-based pricing schemes to a collaborative peer-to-peer data-pricing (pDP) scheme and a cluster-based data-pricing (cDP) scheme to incorporate the notion of 'cluster' (made up of two or more MUs) in mobile communication. Third, our performance study shows that the proposed schemes are indeed effective in maximizing MS subscriptions and minimizing MS's price/user.

이 논문은 인터넷 백본서비스 품질에 대해 서로 다른 반응도를 가진 사용자가 있는 경우, 백본을 보유한 독점적 기업은 자사의 서비스에 대해 가격을 어떻게 차별화 하는가를 분석하고 있다. 특별히, 인터넷 사용에 있어 혼잡이 있는 경우, 비선형적인 가격책정이 어떻게 진행되는 것인가에 초점을 맞추고 있다. 인터넷 혼잡효과를 고려할 경우, 제공되는 서비스 품질은 특수한 상황 하에서 망사용자의 전략적 형태와 인터넷 상에 제공되는 어플리케이션의 특성과 무관하게 사회적 최적으로 제공할 수 있음을 보여주고 있다. 또한 사회적 최적품질의 서비스가 제공되지 않는 경우에 있어서 파라미터의 조건들을 제시하고 있다.
