Tintor Vladica,Jankovi? Milan,Mili?evi? Vlade
Economic Annals , 2010, DOI: 10.2298/eka1085107t
Abstract: In this paper we examine ex ante electronic communications market analysis in the European Union's regulatory framework. We start with the analysis of relevant markets in accordance with the 1998 regulatory framework. Then we examine the 2002 regulatory framework through the definition of relevant markets, market analysis, SMP analysis, and adoption of measures for market regulation. We briefly compare the new 2007 regulatory framework with the previous ones. At the end we analyze some drawbacks of market analysis according to EU directives that have occurred in practice.
Romanian Market Researches in Global Market Context

Theoretical and Applied Economics , 2006,
Abstract: Market research is a powerful industry, whose value reached 21,5 billion USD in 2004. Market studies expenses are mostly concentrated in Europe (45%) and in USA (37%). The market shares of the Top 10 companies were above fifty per cent of the research market’s turnover. As a young, modest market, which is 0,84% of the global expenses value, Romania was the global leader in terms of growth, in 2004. With an asymmetric demand and a relatively concentrated offer, the Romanian research market may have a spectacular development in the future, if the obstacles for the customers and research companies are surpassed. If so, the pressures following the UE’s entry of Romania and the evolution of customers needs and expectations will speed up the growth of the market research.
Improve Communication Quality by Understanding Customer Switching Behavior in China’s Telecom Sector  [PDF]
Salman Awan, Yanxia Cheng
iBusiness (IB) , 2016, DOI: 10.4236/ib.2016.84008
Abstract: This paper analyzes telecom consumer relationship by exploring customer switching behavior and classifying communication categories to support companies in planning applicable communication to thwart the consumer switching and improving consumer loyalty. Quantitative research is carried out by surveying 383 telecom consumers who have experienced the switching process. Findings uncover that telecom consumers selected distinct information methods before making switching decision. Active consumers prefer newsletter based on quality of service while passive consumers select newsletter largely based on competitive prices.
Collective behavior in financial market  [PDF]

Abstract: Financial market is an example of complex system, which is characterized by a highly intricate organization and the emergence of collective behavior. In this paper, we quantify this emergent dynamics in the financial market by using concepts of network synchronization. We consider networks constructed by the correlation matrix of asset returns and study the time evolution of the phase coherence among stock prices. It is verified that during financial crisis a synchronous state emerges in the system, defining the market's direction. Furthermore, the paper proposes a statistical regression model able to identify the topological features that mostly influence such an emergence. The coefficients of the proposed model indicate that the average shortest path length is the measurement most related to network synchronization. Therefore, during economic crisis, the stock prices present a similar evolution, which tends to shorten the distances between stocks, indication a collective dynamics.

Majlesi Journal of Electrical Engineering , 2009, DOI: 10.1234/mjee.v3i4.97
Abstract: The goal of this paper is to estimate the capital investment in telecom network's equipments, by using Cobb-Douglas model to predict the number of subscribers for the next years of Iran. By presenting a master plan for "fixed telephony", "mobile telephony", "data", "transmission", and "access" networks, the required equipments and also the capital investment amounts are estimated. Because of the importance of operations' support systems (OSS) in the next generation networks (NGN), the amount of required capital investment for deployment of network management systems (NMS) and customer care and billing systems (CCBS), as main parts of OSS, are calculated for the next three years in this paper. To reach these estimates, the total number of subscribers in the mentioned networks is forecasted for the period 1387-90. This assessment shows an approximate investment of M7017$ for the five mentioned networks, as the total telecom equipments' market in the country. The required investment for OSS is estimated to be M688$ in the same period. An approximate investment of M399$ and M289$ is needed for NMS and CCBS, respectively.
Some Dynamic Market Models  [PDF]
Jan A. Audestad
Quantitative Finance , 2015,
Abstract: In this text, we study the temporal behavior of markets using models expressible as ordinary differential equations. The markets studied are those where each customer buys only one copy of the good, for example, subscription of smartphone service, journals and newspapers, and goods such as books, music and games. The underlying model is the diffusion model of Frank Bass. Evolution of markets with no competitors and markets with several competitors are analyzed where, in particulat, the effects of churning upon the market evolution is investigated. Analytic solutions are given for the temporal evolution of several types of interactive games.

International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v4n10p14
Abstract: With the advent of the information age, the importance of IT investment becomes more and more obvious for the survival and development of enterprise, and IT has been the important part of enterprise management, so it is very important to understand the impact of IT investment on the performance of enterprise. Through reviewing and analyzing foreign and domestic empirical research literatures about the influences of the IT investment announcements on the enterprise market value, the influencing factors of IT investment value were divided into IT investment character, organization factor and exterior environment, and the limitations of existing research and future research directions about each factor were studied in the article. Aiming at the disputes about the impact of IT investment on enterprise risk and the methodology, the limitations about existing risk factors and methodology were summarized. This article is an attempt to help scholars to further understand the status and limitations of relative researches. Especially, the status of foreign researches was completely explained in the article, and Chinese scholars could further study Chinese sample data aiming at the limitations of existing researches based on the advantages of foreign researches.

Research on Evolution of Chinese Telecom Industry System Based on Dissipative Structure Theory  [cached]
Fei Chen,XiaoHang Zhang
Journal of Computers , 2011, DOI: 10.4304/jcp.6.4.725-731
Abstract: In this paper, the self-organization evolution mechanism of the telecom industry which is regarded as a complex system is studied based on dissipative structure theory by taking into account the telecom industry's characteristic and practical problems . First, hte characteristic of the dissipative structure of the telecom industry system is proposed through qualitative analysis. Second, the Brusselator model of the telecom industry system is built, and the dynamic condition needed for the telecom industry system to evolve into a dissipative structure is summarized by quantitative analysis of teh evolution equation. Finally, the self-organization evolution mechanism of the telecom industry system is illustrated withe the China telecom industry. Different from traditional qualitative analysis, the dynamic and quantitative method adopted by this study gives a deep insight for the evolution mechanism of the telecom industry's system,and guides the telecom market towards rational development.

Abstract: The authors study in-store marketing for telecom retail stores in GSM sector in Turkey which handset manufacturers practice special application in stores for increasing purchasing and improving suggestion rates of their products. They develop a theoretical model of dealers, and manufacturers behavior based on observations about key aspects of the mobile phone market. The analysis provides important insights about in-store marketing and their applications. For example, owner of the store and salesmen would like to support in-store marketing applications of manufacturers in spite of operators’s in-store rules. The authors find empirical support when they test the theoretical results.
