Smart Dynamic Pricing has been introduced to address the under-utilised network resources problem in mobile telecommunications systems. In this paper, we investigate the applicability of Smart Dynamic Pricing and its signalling models into Cognitive Radio Systems. Cognitive Radio System is defined as one in which cognitive radios are employed to access shared spectrum and/or dynamically allocated spectrum. Network elements, protocols, traffic and control channels, and system architecture are proposed for the implementation of Smart Dynamic Pricing in Cognitive Radio System. It is found that Smart Dynamic Pricing and its signalling models can be applied to Cognitive Radio Systems.

One of the major challenges confronting a multiservice electric utility is the establishment of the right prices for its services. The key objectives of particular pricing schemes are reasonableness of company earnings, economic efficiency, the responsiveness of supply and of the allocation of sources to the desires of consumers, and maintenance of some degree of competition. This paper proposes a value-based pricing mechanism amenable to the current deregulation situation in electricity market allowing service differentiation. The proposed pricing mechanism can be implemented in a nodal auction model, and can also be applied to direct load control.

본 논문에서는 다중클래스 통신망을 위한 새로운 과금 (pricing) 기반의 호수락 제어 (call admission control) 알고리즘 제안한다. 본 알고리즘에서는 통신망에 새롭게 호가 도착하게 되면, 요청 회선의 수와 필요로 하는 최소 시간을 통신망에 알려준다. 통신망은 기대 수익 (expected revenue)을 최대화하는 최적의 과금을 계산하여 호에 제안한다. 이때, 최적 과금은 도착한 호의 정보와 현재 그리고 미래에 추정되는 호 예약시간 동안의 망내 정체(congestion) 정도를 기반으로 동적으로 조정된다. 호가 제안된 과금을 수락하면 호는 연결이 되고 그렇지 않으면 연결이 되지 않는다. 본 논문에서는 제안된 동적 과금 기반 호수락 제어 알고리즘의 성능을 Courcoubetis와 Reiman[1] 그리고 Paschalidis와 Tsitsiklis [2]의 정적 과금 기반 호수락 제어 알고리즘의 성능과 비교한다. 비록 두 알고리즘은 거의 같은 수익 결과를 보이지만, 동적 알고리즘이 정적 알고리즘에 비해 더 높은 호 수락율과 각 호에 낮은 과금을 제안하는 측면에서 더 뛰어난 성능을 나타냄을 보인다. 이는 경쟁 상황에서 정적 가격 알고리즘에 비해 동적 가격 알고리즘이 더 많은 사용자를 끌어들여 수익을 더 낼 수 있음을 의미하며 더 나아가 접속 요금이 과금에 고려된다면, 동적 과금 호수락 제어 알고리즘이 더 많은 수익을 낼 수 있음을 보인다.

관련 기업 및 ISP 업체에게는 투자의 매력을 부여하며 인터넷의 사용시간대 및 사용량에 따라 빈약한 사용자, 건강한 사용자, 과다한 사용자 등으로 구분하여 차등요금을 부여하는 합리적인 전략이 필요하다. 이 논문에서 차등요금부과의 타당성을 검토한다. 그리고 로지스틱 회귀모형을 이용하여 혼잡에 따른 차등요금, 지연시간, 접속만족도 등에 따라 실제적으로 인터넷 사용자들이 인터넷 접속을 얼마나 유지하는 지를 측정할 수 있는 관련 예측모델을 제시한다. 이러한 예측모델을 이용하여 인터넷 접속 또는 비접속 확률을 예측하는 분석률은 $69.5\%$이었음을 확인하였다.

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.

This study performed an analysis on power demand reduction effects exhibited by demand response programs, which are advanced from traditional demand-side management programs, in the smart grid environment. The target demand response systems for the analysis included incentive-based load control systems (2 month-ahead demand control system, 1~5 days ahead demand control system, and demand bidding system), which are currently implemented in Korea, and price-based demand response systems (mainly critical peak pricing system or real-time pricing system, currently not implemented, but representative demand response systems). Firstly, the status of the above systems at home and abroad was briefly examined. Next, energy saving effects and peak demand reduction effects of implementing the critical peak or real-time pricing systems, which are price-based demand response systems, and the existing incentive-based load control systems were estimated.

Transfer pricing is a matter of concern for countries. It affects the interests of the parties involved in the commercial transaction. Through manipulation of prices in transactions, businesses take advantage of tax rates in a country to adjust profits for economic gain. This affects the fairness and rationality of economic transactions between related parties. The article uses a two-year time series from 2018 to 2019 of 50 foreign direct investment enterprises in Vietnam. The article uses ordinary least squares to test the hypotheses of the research model. The article uses four independent variables related to ownership structure affecting transfer pricing decisions including total ownership, organization ownership, concentration ownership, and area ownership. Research results show that two variables have a positive influence on transfer pricing decisions including total ownership and organization ownership. Organization ownership has a higher degree of influence than total ownership. To be able to control transaction activities related to transfer pricing, Vietnam's state management agencies need to pay attention to perfecting the legal framework based on supplementing and amending regulations related to transfer pricing. Legal regulations need to be regulated based on international common practices to ensure uniformity on a global scale.

Recently the international transfer pricing became the most popular topic in accounting of the research as well as of the practice. Modern corporations have been experiencing a lot of changes in managerial control technique as their scale and scope of activities grows and the environment in which they operate changes rapidly. If there are internal transactions in a decentralized firm, the necessity of coordination among the divisions is inevitable. Transfer pricing in a decentalized company provides an excellent example of the coordinating role of information. One of the most important reason for a form to have a decentalized structure is the improved decision making at the lower level due to better access to information. International transfer pricing is not merely a problem of pricing but coordination of transfers and other collective or individual actions to derive rents from intergration. Such coordination can be achived through the performance evaluation scheme which is partly based upon transfer price.

The Real-Time-Pricing (RTP) brings greatest values in terms of economic incentives and efficiency among the dynamic pricing schemes. The electric power industry in Korea is mainly operated by publicly owned utilities and strongly regulated by the government; therefore, revenue reconciliation of RTP is inevitably required to prevent revenue deficits. In this paper, a revenue reconciliation of real-time pricing considering imperfect information on customer response is proposed to prevent revenue deficit and distortion of the spot price. A case study is present to verify the applicability of the proposed method.

It is difficult to determine an appropriate discount price for daily perishable products to increase profit from a long-term standpoint. Even if the discount pricing is efficient to increase profit of the day, consumers memorize the sales price and they might hesitate to purchase the product at a regular price the following day. The authors discussed the inventory clearance pricing for a single period in our previous study by constructing a mathematical model to derive an optimal sales price to maximize the expected profit by considering the reference price effect of demand. This paper extends the discussion to handle the discount pricing for multiple periods. A mathematical analysis is first conducted to reveal the properties on an objective function, which is the present value of total expected profits for multiple periods. An algorithm is then proposed to derive an optimal price for asymmetric consumers. Numerical experiments investigate the characteristics of the objective function and optimal pricings.
