An Analysis of Service Trading Architectures

Automating the creation and management of SLAs in elec tronic commerce scenarios brings many advantages, such as increasing the speed in the contracting process or allowing providers to deploy an automated provision of services based on those SLAs. We focus on the service trading process, which is the process of locating, selecting, nego tiating, and creating SLAs. This process can be applied to a variety of scenarios and, hence, their requirements are also very different. Despite some service trading architectures have been proposed, currently there is no analysis about which one fits better in each scenario. In this paper, we define a set of properties for abstract service trading architectures based on an analysis of several practical scenarios. Then, we use it to analyse and compare the most relevant abstract architectures for service trad ing. In so doing, the main contribution of this article is a first approach to settle the basis for a qualitative selection of the best architecture for similar trading scenarios

Characterization and Modeling of Spectrum Trading Markets

Telecommunication regulators are facing increasing pressure to make spectrum resources more widely available to new wireless services and providers. In spectrum trading markets, buyers and sellers determine the assignments of spectrum and, possibly, its uses. These markets are being considered or implemented by the regulatory bodies of many countries as a way to provide increasing efficiency in the use of spectrum and attend the demand for this resource. This work describes a classification for the implementation of spectrum trading markets and a way to model them and identify the conditions for their viability. Specifically, we make use of Agent-Based Computational Economics (ACE) to model the participants in these markets, analyze the behaviors that emerge from the interactions of its participants and determine the conditions for viable markets. Our results, provide guidelines that can be used by regulators and wireless service providers for the design and implementation of these markets

The Trans-Pacific Partnership Agreement

[Excerpt] The economic and strategic architectures of Asia are evolving. One part of this evolving architecture is the Trans-Pacific Partnership Agreement (TPP), a free trade agreement that includes nations on both sides of the Pacific. The existing TPP, which originally came into effect in 2006, consists of Brunei, Chile, New Zealand, and Singapore. The United States, Australia, Peru, and Vietnam have committed themselves to joining and expanding this group. The third round of discussions among the eight countries took place in Brunei, during the week of October 4, 2010. The third round saw the formal inclusion of Malaysia in the negotiations. Other architectures, such as the Association of South East Asian Nations (ASEAN), Asia-Pacific Economic Cooperation (APEC) forum, and the East Asia Summit (EAS) have both economic and strategic aspects. They can be grouped into two categories: (1) groupings that are Asia-centric in approach or origins and exclude the United States, and (2) those that are Trans-Pacific in nature and that include, or would include, the United States and other Western Hemispheric nations. The TPP is one vehicle that could be used to shape the U.S. agenda with the region. The United States, by signaling its intention to join the EAS and by working to elevate its relationship with ASEAN to a more strategic level, appears to be shaping regional architectures in a way that will be more inclusive and trans-Pacific in nature. Asia is viewed as of vital importance to U.S. trade and security interests. According to the U.S. Trade Representative, the Asia-Pacific region is a key driver of global economic growth and accounts for nearly 60% of global GDP and roughly 50% of international trade. Since 1990, Asia-Pacific goods trade has increased 300% while there has been a 400% increase in global investment in the region. The United States has pursued its regional trade interests both bilaterally and through multilateral groupings such as APEC, which has linked the Western Hemisphere with Asia. There appears to be a correlation between increasing intra-regional economic activity and increasing intra-regional political and diplomatic cooperation. Many observers view the more recent intra-Asian Association of Southeast Asian States (ASEAN) plus three—China, Japan, South Korea—and the ASEAN plus six (also known as the East Asia Summit)—China, Japan, South Korea, India, Australia, New Zealand—groups as having attracted more interest within the region in recent years. China\u27s rapidly expanding economy and Japan\u27s developed economy have made them attractive trading partners to many Asian nations. Until recently, many regional states also viewed the United States as having been distracted by events in Iraq and Afghanistaa This had led some to increasingly look to China and Japan as key partners. China may be shifting to a more assertive posture in the region, which may affect relations in the region. Secretary of State Clinton attended the East Asia Summit in Hanoi in October 2010 and President Obama stated he plans to attend the 2011 East Asia Summit in Jakarta. U.S. participation in the TPP involves the negotiation of FTAs with New Zealand, Brunei, Malaysia, and potentially, Vietnam. The United States currently has FTAs in force with Chile, Singapore, Australia, and Peru. Bilateral negotiations with New Zealand may focus on agricultural goods such as beef and dairy products. The possible inclusion of Vietnam has proven controversial from the standpoint of certain U.S. industry groups, such as textiles and apparel, as well as those concerned with labor, human rights and intellectual property issues. The involvement of Vietnam could add a higher level of difficulty, yet is illustrative of the challenges associated with developing a truly Asia-Pacific-wide trade grouping. All the potential parties may face complex negotiations in integrating the myriad FTAs that already exist between some TPP parties

The viability of spectrum trading markets

Spectrum trading markets are of growing interest to many spectrum management agencies. They are motivated by their desire to increase the use of market based mechanisms for spectrum management and reduce their emphasis on command and control methods. Despite the liberalization of regulations on spectrum trading in some countries, spectrum markets have not yet emerged as a key spectrum assignment component. The lack of liquidity in these markets is sometimes cited as a primary factor in this outcome. This work focuses on determining the conditions for viability of spectrum trading markets by considering scenarios with different market structures, number of trading participants and amount of tradable spectrum. We make use of Agent-Based Computational Economics (ACE) to analyze each market scenario and the behaviors of its participants. Our models indicate that spectrum markets can be viable in a service if sufficient numbers of market participants exist and the amount of tradable spectrum is balanced to the demand. We use the results of this analysis and the characteristics of the viable markets found to make recommendations for the design of spectrum trading markets. Further work will explore more complicated scenarios. ©2010 IEEE

Automated ANN alerts : one step ahead with mobile support

In this paper, I examine the potential of mobile alerting services empowering investors to react quickly to critical market events. Therefore, an analysis of short-term (intraday) price effects is performed. I find abnormal returns to company announcements which are completed within a timeframe of minutes. To make use of these findings, these price effects are predicted using pre-defined external metrics and different estimation methodologies. Compared to previous research, the results provide support that artificial neural networks and multiple linear regression are good estimation models for forecasting price effects also on an intraday basis. As most of the price effect magnitude and effect delay can be estimated correctly, it is demonstrated how a suitable mobile alerting service combining a low level of user-intrusiveness and timely information supply can be designed
