Title: Three essays on competition and regulation
Creator: Lee, Dong-Ryeol
Date: 2010
Collection: Electronic Theses & Dissertations
Description: Chapter 1: Cost-based Termination Charge Regulation when Fixed and Mobile Networks Compete for SubscribersThis paper studies termination charges in the telecommunications industry (i.e., the fees for receiver's network to impose on caller's network for call termination services). I address two unsettled questions on termination charges: (i) why mobile networks have incentives to set above-cost termination charges and (ii) what are the welfare consequences of symmetric cost-based...
Show moreChapter 1: Cost-based Termination Charge Regulation when Fixed and Mobile Networks Compete for SubscribersThis paper studies termination charges in the telecommunications industry (i.e., the fees for receiver's network to impose on caller's network for call termination services). I address two unsettled questions on termination charges: (i) why mobile networks have incentives to set above-cost termination charges and (ii) what are the welfare consequences of symmetric cost-based termination charge regulation. I propose an oligopolistic Hotelling model which explicitly considers the competition for subscribers between fixed and mobile networks and show that such competition can potentially explain high mobile termination charges. When both mobile-to-mobile and fixed-to-mobile substitutions are present, there exists a tradeoff from above-cost mobile termination charges: (i) profit gain from mobile market expansion and (ii) profit loss from intense price competition. I show that above-cost mobile termination charges are profitable when the market share effect outweighs the price competition effect - which is likely to occur for a large inter-network customer base or a small inter-network product differentiation. Moreover, the cost-based regulation on fixed and mobile termination charges, which was recommended by European Commission (2009), may have potential welfare-enhancing effects.Chapter 2: Exclusive Dealing and Investment Incentives in the Presence of Risk of Renegotiation BreakdownExclusive dealing (i.e., a contract that prohibits a buyer from trading with other sellers) may affect competition through the investment incentives and entry. My model considers the case where the contracts are renegotiable and the incumbent seller facing a potential entry threat is able to invest in the relationship with a buyer. My paper departs from the existing literature by considering the risk of breakdown in the renegotiation process. In this setup, exclusivity may have contrasting effects on competition through (i) investment promotion and (ii) foreclosure of efficient entry. The profitability and welfare consequences of exclusive dealing are decided by the relative importance of these two effects which in turn mainly relies on the risk of renegotiation breakdown. More specifically, if the risk of breakdown is very low, exclusive contracts will be profitable and welfare-enhancing. However, the profitable and welfare-reducing exclusive dealing is feasible for a sufficiently high risk of breakdown. This paper restores the inefficient foreclosure by exclusive dealing even considering investments and renegotiation, highlighting the role of risk of renegotiation breakdown.Chapter 3: Dynamic Incentives of Tying in Two-sided MarketsThis paper investigates tying arrangements in two-sided markets. Optimal pricing structure of two-sided markets differs from that of standard one-sided markets. In two-sided markets, platforms charge subscription fees in order to utilize inter-group externalities. The main purpose of this paper is to explore how inter-group externalities affect tying incentives through platforms' price and R&D competition. I adopt a two-sided Hotelling model where two platforms compete in prices and investments and show that tying leads to the distortion of R&D incentives as well as the exclusion of rival platforms. Moreover, there exist certain parameter configurations such that tying is profitable and welfare-reducing through foreclosing rival's R&D investments. Dynamic incentives of tying, which have not been considered in the existing literature, provide a new rationale for the regulation on tying in two-sided markets.

Title: The IT worker smart phone conundrum : how work email on smart phones affects stress levels of information technology professionals in it services
Creator: Virag-McCann, Alison
Date: 2013
Collection: Electronic Theses & Dissertations
Description: Information Technology Professionals can often be under a lot of pressure, especially in the department of IT Services. Many IT Services employees have smart phones they use to download work email so that they are available to provide support at any time. This may result in high stress levels from expectations related to multitasking and better productivity. To explore the impacts of using personal smart phones for IT work several IT Professionals were interviewed about their smart phone...
Show moreInformation Technology Professionals can often be under a lot of pressure, especially in the department of IT Services. Many IT Services employees have smart phones they use to download work email so that they are available to provide support at any time. This may result in high stress levels from expectations related to multitasking and better productivity. To explore the impacts of using personal smart phones for IT work several IT Professionals were interviewed about their smart phone usage. Interviewees were asked the same set of questions, but they were prescreened and chosen as participants if they fit one of two profiles: whether they like using their smart phones for work email or dislike using their smart phones for work email. The results showed that how the IT Professionals used their smart phones and their reasoning for using their smart phones appeared to be associated with their stress level. Overall, those who dislike using their smart phones reported experiencing less stress than those that did those who liked using their smart phone for work email. -- Abstract.

Show moreThis articles reviews critically the evolution, present status and future development of telecommunications in the African continent. It reports the major efforts so far made to develop telecommunications technology and services in Africa and points out that despite all these efforts, it is a painful fact that Africa still lags behind in the development of communications. The article attributes this unfortunate situation mainly to economic resource constraints, inefficient planning, inadequate roads, lack of coordination and low priority of communication development. It then calls for greater cooperation among African countries, funding agencies, the United Nations and the industrialized countries in this crucial area of telecommunications development in Africa, for the mutual benefit of all.

Avatar embodiment is discussed as a moderator for the Proteus effect, as well as the need for inducing this embodiment in experimental studies in order to observe evidence of the Proteus effect.

Show moreAvatar-based self-influence in text-based CMC was examined through the lens of self-perception theory and the Proteus effect. Avatar embodiment is discussed as a moderator for the Proteus effect, as well as the need for inducing this embodiment in experimental studies in order to observe evidence of the Proteus effect. Two possible methods for inducing embodiment are tested along with a proposed model for the Proteus effect in social media environments. Significance in this study was found for main effect of a familiarity task on perceptions of avatar embodiment, an interaction effect of avatar embodiment and avatar condition on aggressive behavior, and an unpredicted main effect of embodiment on aggressive attitude. Results are discussed as are possible explanations for the observed effect of embodiment on aggression.
