The Objective of this thesis is to address some interesting problems in the Indian cellular services market. The first problem we address relates to identifying important change points that marked the evolution of the telecom market since Indian Independence. We use the data on per-capita availability of telephones in India to this effect. We identify important change points that mapped to the computerization move in 1989, the liberalization and globalization policies starting from 1991 and subsequently the introduction of NTP 1997 and NTP 1999. We also identify the important change points that mark the growth of cellular services subscriber base in India. We map change points detected to some of the important macro level policy initiatives that were taken by TRAI. The second problem we address is the assessment of policy interventions on the growth of cellular subscriber base in India. We model the impact of two important policy interventions namely, the NTP 1999 and its spill-over policy the entry of the fourth player into the market to offer services. We model the abrupt temporary, abrupt permanent and gradual permanent impacts of these interventions individually and in a coupled manner. We are arguably the first to use the intervention analysis and change point analysis to study the Indian telecom market. The third problem relates to the most challenging task of forecasting the growth of cellular services subscribers in India. We use novel machine learning techniques like ε-SVR and ν-SVR and compare its performance with ANN and ARIMA using standard performance metrics. Initially, we venture to predict the aggregate subscriber growth of cellular mobile subscribers in India using the SVR techniques. This would be of interest to the policy makers from a strategic standpoint. Subsequently, we predict the marginal(monthly) subscriber growth using SVR and tabulate the results for varying depths of forecasting which would be of interest to service providers form an operation standpoint. We find that the SVR techniques performed better than ANN and ARIMA particularly with respect to forward or out-sample forecasting when the time periods increase. The final problem involves a differential game model in an oligopoly set up for the telecom service providers who tried to optimize their advertisement innovation mix in order to maximize their discounted flow of profits. We consider the situation where the service providers make Cournot conjectures about the action of their rivals. The firms would not enter into agreements or form cartels. The firms choose the quantity they want to sell simultaneously. The essence of the Cournot conjecture was that though it was a quantity based competition, no single firm could unilaterally try to improve the total quantity sold in the market. Every firm made only one decision and did so when other firms were simultaneously making decisions. We have come across papers that considered either advertisement or product/process innovation separately but not together. We incorporate both these control variables with the inverse demand function as the state variable. We propose an open-loop solution that is dependent on time. We conduct experiments with various combinations of churn and spill-over rates of advertisement and innovation and thereby get some managerial insights.

Dans le cadre de la réforme de l’État en France, le secteur des télécommunications, auparavant intégré à l'administration des PTT, a été détaché de celle-ci par la loi du 2 juillet 1990, qui a conduit à terme à sa privatisation. Cette dernière, dont un des objectifs était la réduction des dépenses publiques principalement par celle du personnel, a été supportée pour l'essentiel par celui-ci ; au mépris de son statut de fonctionnaire de l’État, dont il s'était vu garantir le maintien, et auquel sera progressivement substitué de facto le régime courant du droit du tram.il, à travers la multiplication de catégories aux défini1ions souvent ambiguës. A défaut de pouvoir recourir aux licenciements directs, un management brutal aux effets parfois dramatiques s'est exercé dans le cadre de l'entreprise France Télécom/Orange, pour susciter des départs volontaires. Il a ciblé et cible encore tout particulièrement les agents ayant explicitement manifesté leur attachement au statut de la fonction publique. Les autres objectifs de l'opération - ouverture au marché, présentation et amélioration du service public des télécommunications - ont-ils été réellement remplis ? On peut en douter. Certes, la modernisation des services, leur multiplication et l'intégration des progrès technologiques ont eu lieu. Mais malgré la multiplication des opérateurs, les effets d'une concurrence imparfaite, dont les principaux bénéficiaires ont été les entreprises, sont restés limités en termes de tarifs pour les particuliers. Quant au service public, on peut se demander dans quelle mesure ses principes - et notamment l'égalité de tous les usagers et la mutabilité - ont survécu, devant la disparition des supports de communication traditionnels au bénéfice d'une dématérialisation généralisée, facteur aggravant de l'exclusion sociale. Ce volet de la réforme participe du recul général de la place de l’État dans l'économie et la société française, et de l'alignement progressif de la France sur des normes européennes. Il interroge ce faisant sur les méthodes appliquées. Flou et imprécision des textes de lois, décrets et règlement, et surtout interprétation élastique de ces derniers par les autorités juridictionnelles : ces pratiques interrogent quant au rôle, mire à la légitimité de la justice administrative, spécificité institutionnelle française. Elles questionnent aussi quant à l'évolution même du Droit en France, devant cette étonnante «souplesse». / The French telecommunications sector, previously part of the postal administration (Ministère des PTT), has been within the State reform framework in France, detached from the department by the July 2 1990 law, which would eventually lead to its privatization.Reducing public expenditure was the main point of the reform, the burden of which was mainly borne by the staff. As tenured civil servants, they were employed under an integrated statutory law, a position that had been guaranteed, and forbade direct layoffs. But the tenures were gradually replaced by fixed-term contracts, using a blurred pattern of ranks ; and management by the raking over company, France-Télécom/Orange, was soon notorious for its various and at times life­endangering forms of workplace violence, aimed at enticing voluntary resignation. The harassing management targeted, and is still targeting, mainly those employees who had mainly voiced their attachment to the public service. The reform had more goals, such as creating an open market, improving and enlarging public telecommunications service. Were these actually- fulfilled ? One may doubt. Modernization and enlarging of services, and integration of technological advances did rake place. But despite the fact that there were now many network operators, the market remained only partly open. Companies benefited, but nor the public, as rates did not drop as much as expected . As for the availability of the telecommunications public service, one may wonder to what extent its main features - notably equality of all users - survived, as the traditional fixed line communications system is currently being replaced by dematerialized networks, a process that eventually broadens the gap of social exclusion. Reform in French telecoms sector testifies to the general decline of the state's role in French economy and Society , and to the gradual compliance of the country to European standards. One can question the management of the process. Laws, decrees and regulations have been unclear and blurred ; and jurisdictional authorities have been using them in a most elastic way. This leads by the way to questioning the place and legitimacy of a specifically French institution, the “justice administrative”, and to wonder at the evolution of the legal system in France, in this case surprisingly “pliable”.

The content of this work is to focus on the concept of corporate image and its analysis of the selected company, which is in this case T-Mobile Czech Republic a.s. Analysis of the company's image comes from the first analysis of its identity and elements of corporate identity, which consists of finding and subsequently image perceived by employees and consumers in the Czech market through questionnaires. It is shown by a comparison of some elements of the main competitors in the industry. Finally was given some recommendations for improvement of certain activities of the company, which in turn may positively affect the company's image.

Information, communication and broadcasting convergence is changing the business landscape in South Africa, as organisations adopt new converged information, communication technology (ICT) products and services to satisfy the needs of customers. Simultaneously, major changes are taking place in the South African telecommunications business environment creating new marketing opportunities and threats for Telkom SA, the only fixed line telecommunication operator in South Africa. Some of the findings of the study are • the commodization of the fixed line telecommunication network • political and regulatory changes are reshaping the telecommunications landscape by allowing the entry of new competitors • new technological innovations in Information Communication Technology (ICT) and mobile communication is driving change • social and economic change is fueling the speed of environmental change poor economic climate is quickening the competitive pace amongst South African businesses forcing them to attain efficiencies and effectiveness for survival • organisations worldwide are competing for limited resources and markets and turning to ICT to achieve their objectives • customer needs are changing - demanding better and innovative communication products and services - providing opportunities to competitors • the Internet is reshaping traditional business models as businesses are seeking to establish competitive advantages through the Internet • the migration of the Internet to the mobile telephony sector These changes are creating new marketing opportunities and threats for South African fixed line telecommunication operators and are threatening the survival of fixed line telecommunication operators worldwide and in South Africa. Information Technology, broadcasting and telecommunication technology convergence, has created many new ICT products and services opportunities that telecommunication competitors are offering existing customers of the fixed line operators network indicating lethargy from their side. In order for the fixed line operators to survive they must apply innovation and revise their strategic planning models. / Business Management / DCOM (Business Management)
