In the last few years the mobile telecommunications industry has witnessed the entry of a large number of new service providers. Traditionally, mobile users get their mobile services from the service providers owned by vertically integrated mobile network operators (MNOs). The new entrants do not own a network of their own however, because they use the existing mobile infrastructure, i.e. they are 'mobile virtual network operators' (MVNOs). By granting these virtual operators access to their networks, MNOs actually facilitate the entry of potential competitors for their own downstream service providers. These new entrants might attract additional users by offering competitive services and create extra value with their well-known brand names and other complementary assets. This study focuses on the mobile market of the Netherlands, where competition is intense and MVNOs proliferate. The aim of this research is to improve our understanding of the entry of virtual operators in general, and specifically by explaining why and how virtual operators enter the mobile market and the impact they have on competition in the mobile market.  相似文献

Scarcity of spectrum limits the number of competing network operators in mobile telecoms. In the United Kingdom a regulatory review is currently enquiring into the effects of limited competition in the mobile market. The European Commission is also reviewing competition in roaming across mobile networks in Europe. In the UK the industry regulator Oftel claims that the prices for calling mobile phones are too high. We show that such relatively high prices stem from asymmetric incentives. The convention in the UK is for the originating party to pay for a telephone call. If instead the receiver were to pay for some or all of a call, we show that prices of calls to mobiles would be lower. We also argue that qualified indirect access could stimulate more effective competition in mobile telecoms.  相似文献

This study examines how firms interpret new, potentially disruptive technologies in their own strategic context. The study uses a propositional framework for evaluating the amount of radical change in the companies' business models with two middle variables, the disruptiveness potential of a new technology, and the strategic importance of a new technology to a firm. The framework is used in a cross-case analysis of four potentially disruptive technologies or technical operating models: Bluetooth, WLAN, Grid computing and Mobile Peer-to-peer paradigm. The technologies were investigated from the perspective of three mobile operators, a device manufacturer and a software company in the ICT industry.The data was gathered in group-discussion sessions in each company. The results of each case analysis were brought together to evaluate, how firms interpret the potential disruptiveness in terms of changes in product characteristics and added value, technology and market uncertainty, changes in product-market positions, possible competence disruption and changes in value network positions. The results indicate that the perceived disruptiveness in terms of product characteristics does not necessarily translate into strategic importance. In addition, firms did not see the new technologies as a threat in terms of potential competence disruption.  相似文献

The relative lack of competitive pressure in product markets and lower investment in both fundamental and applied innovation are among the potential factors that have been put forward to explain Canada’s weak productivity performance with respect to the US. Since competition is generally seen as the single leading catalyst for fundamental and applied innovation, this paper analyzes the role of product market competition in the Canada–US productivity level gap. We develop an empirical framework in which competition exerts both direct and indirect effects on productivity, with the indirect impact coming through fundamental and applied innovation. We find statistically significant evidence that the competition intensity differential (between Canada and the US) has contributed to the Canada–US productivity level gap directly, as well as indirectly through lower investment in both R&D activities and M&E (including ICT) investment. We also find statistically significant evidence that Canada’s relatively poor performance in both productivity and M&E (including ICT) investment have acted as a self-reinforcing mechanism, which further causes detriment to the country’s productivity.  相似文献

This study examines the growth in total factor productivity (TFP) of 12 Asia–Pacific telecommunications carriers for the period 1987 through 1990. Carriers are chosen to represent the stages of telecommunications liberalisation identified by the International Telecommunication Union (1995a). A model relating TFP growth to output growth, changes in output mix, technology change and market competition and private ownership is estimated on a unique data set obtained from telecommunications carrier annual reports. Empirical results show competition, private ownership, technology change and scale economies improve carrier TFP growth.  相似文献

We model competition between two unregulated mobile phone companies with price-elastic demand and less than full market coverage. We also assume that there is a regulated full-coverage fixed network. In order to induce stronger competition, mobile companies could have an incentive to raise their reciprocal mobile-to-mobile access charges above the marginal costs of termination. Stronger competition leads to an increase of the mobiles’ market shares, with the advantage that (genuine) network effects are strengthened. Therefore, ‘collusion’ may well be in line with social welfare.   相似文献

Localized technological change is the endogenous outcome of the interplay between substitution costs. Switching costs and learning processes. New technologies are introduced when market pressures induce firms to change the levels of their inputs and their techniques. The dynamics ol localized technological change is the result us the interaction between three processes: it) the Schumpcterian competition process as analyzed by the replicator dynamics and failure inducement mechanisms. b) factor substitution stemming from changes in factors markets. and c) post-Keynesian demand pull pressures resulting from productivity growth. In such conditions out-of-equilibrium exchanges and localized technological changes drive a recursive process that is path-dependent in two senses, first it is highly sensitive to the initial conditions of the system. and second it is shaped by the interactions of agents.  相似文献

This paper empirically assesses the effect of liberalisation and competition on innovation in the postal sector. The analysis is restricted to end-to-end competition. The effect on the incentives to innovate of letter volume, public ownership and other control variables is also tested. Data on liberalisation, competition and innovation in the postal sector is collected for seventeen European countries over eleven years. Three measures are used as proxies for innovation: (1) an innovation index based on a survey conducted for this purpose; (2) the accumulated number of innovations (based on the same survey); and (3) labour productivity. We also develop a liberalisation index to measure the percentage of market liberalised (in terms of letter volume). Several models are estimated by GLS. In general, the models estimated have a high explanatory power. We find evidence that market liberalisation has a positive effect on innovation and that an increase in the market share of the competitors stimulates the investment in innovation, at least until the market share of the competitors reaches a certain threshold. Letter volume is also significant and has a positive impact on innovation. GDP per capita turns out to be significant and has a positive relationship with innovation in all the models estimated.  相似文献

The regulation of fixed-to-mobile (F2M) termination charges has become increasingly important in Europe, Australia, and New Zealand under the Calling Party Pays principle. In the absence of any regulation, mobile operators have an incentive to set F2M termination charges “too high”. We show that the setting of the optimal F2M termination charges depends on the significance of network externalities, the intensity of competition in the mobile sector, and the distribution of customer preferences. We also discuss the merits of possible remedies which are not very intrusive. Tommaso Valletti has advised the European Commission and the UK regulator (OFCOM) on mobile termination and Frontier Economics has acted as advisor to a number of mobile operators on the same issue. The views expressed in this paper are those of the authors alone. We thank Carlo Cambini, Yulia Kossykh, participants to the 15th Biennial International Telecommunications Society Conference, the 3rd International Conference on Applied Infrastructure Research in Berlin, for their comments. We also thank the editor Michael Crew and two anonymous referees for many suggestions that have greatly improved the paper.  相似文献

We ask how the scope for non‐profit objectives in a state‐owned enterprise (SOE) in a mixed oligopoly changes because of competition from firms in another country. There is no change if costs and demand are given, unless the trade partner is a low‐cost country. However, the scope for non‐profit objectives is limited by the country's relative size if wages are market‐clearing and if workers and firms are stationary, because of reduced competitiveness caused by higher real wage rates. The total surplus is then not affected by the actions of the SOE. International trade does not otherwise reduce the scope for its non‐profit objectives if workers and firms are mobile, but productivity differences might require restrictions in order to avoid a complete relocation of the workforce in either country.  相似文献

This paper examines the role of ownership and market competition in Vietnamese firms’ total factor productivity (TFP) from 2001 to 2011. Making use of a large panel dataset of manufacturing firms, we find that, on average, both foreign-owned enterprises (FOEs) and state-owned enterprises (SOEs) have performed better than privately owned enterprises (POEs) in terms of their TFP levels. However, while FOEs’ TFP ranked the highest in the period 2001–2006, SOEs “closed the gap” in the period 2007–2011. Moreover, we find that market competition has been effective in enhancing average firm productivity and in reducing the gaps in efficiency across ownership types. SOEs’ remarkable performance may be linked to several concurrent factors experienced during the period 2001–2011, namely, the process of restructuring the state sector during the 2000s, the increased economic integration due to the country's accession to the World Trade Organization (2007) and, finally, the preferential access to financial capital and land granted to SOEs. While some evidence supports SOEs’ equitization as an explanation for their remarkable productivity performance, WTO accession and cheaper access to inputs do not fully explain it.  相似文献

This research examines a performance comparison of the Lotka–Volterra (LV) and extended Bass models in the saturated mobile phone market of the Republic of Korea. A three species LV model is developed and applied to Korean mobile phone service providers in terms of competitive impact. Fitting the historical data of the Korean mobile communication service market, the results show that the goodness of fit of the three species LV model in the case of competition among three companies is better than that of the extended Bass model. The advantages and disadvantages of the two models are discussed based on the results of empirical tests.  相似文献

This paper investigates the effect of ownership and competition on Indian bank productivity since the 1991 reforms. We find that Indian private banks dominate the public and foreign banks both in terms of productivity levels and productivity growth, with the new Indian private banks leading the charge. Competition has a positive impact on productivity for the old Indian private banks, and all the other banks are hurt by competition — the worst hit being new Indian private banks. A similar picture emerges on the productivity growth side, with the new Indian private bank productivity growth being the worst affected as competition increases. An analysis of the pre- and post-1998 periods shows that the latter period displays a much higher productivity gap between the Indian private banks and the public and foreign banks. Indian private bank productivity and productivity growth suffer due to increasing competition in the post-1998 period.  相似文献

This paper provides empirical evidence on the effects of regulatory changes in the market power of Spanish banks. It also analyses the response of banks, in terms of risk-taking behaviour, as a result of a reduction in economic profits. We find that liberalisation measures have increased competition and eroded banks’ market power. We observe that banks with lower charter values tend to have lower equity-assets ratios (lower solvency) and to experience higher credit risk. The last evidence is new in the literature and calls for strengthening regulatory concerns about credit risk management by banks in situations of increased competition.  相似文献

Market Size, Trade, and Productivity   总被引:26,自引:1,他引:25  
We develop a monopolistically competitive model of trade with firm heterogeneity—in terms of productivity differences—and endogenous differences in the "toughness" of competition across markets—in terms of the number and average productivity of competing firms. We analyse how these features vary across markets of different size that are not perfectly integrated through trade; we then study the effects of different trade liberalization policies. In our model, market size and trade affect the toughness of competition, which then feeds back into the selection of heterogeneous producers and exporters in that market. Aggregate productivity and average mark-ups thus respond to both the size of a market and the extent of its integration through trade (larger, more integrated markets exhibit higher productivity and lower mark-ups). Our model remains highly tractable, even when extended to a general framework with multiple asymmetric countries integrated to different extents through asymmetric trade costs. We believe this provides a useful modelling framework that is particularly well suited to the analysis of trade and regional integration policy scenarios in an environment with heterogeneous firms and endogenous mark-ups.  相似文献

A host of industrialised countries have seen concentration in their industries grow. This trend is fuelling concerns about falling competition. This article focuses on the changing pattern of market concentration in Australia from 2002 to 2017. On average, market concentration has been rising. However, beneath the aggregate statistics, the pattern is rather mixed, with concentration falling in several sectors. The study also detects a pattern of strong productivity growth alongside a shift towards capital intensive operation and increasing trade where concentration is growing. Overall, the implications of these findings point to the possibility that rising market concentration in some industries is technology driven and not due to a lack of competition.  相似文献

With the emergence of smartphones, the paradigm of the mobile ecosystem has changed rapidly. In particular, global mobile firms focus on technological competition when jostling for market position in recognition of the strategic need to secure a strong mobile platform. In this paper, we analyse the network structure of technological knowledge flows in mobile ecosystems using US patent citation information. We find that two subsectors, platform providers and application and software providers, are at the centre of knowledge exchange activity and play a brokerage role as the key knowledge mediator. Then, we categorise mobile firms into five different groups based on the patterns of their network centrality: knowledge keystone players, knowledge-distributing mediators, knowledge-absorbing mediators, catch-up players, and pure knowledge receivers. The categorisation of firms demonstrates that knowledge flows in the mobile industry converge towards a few leading firms, and such patterns are shaping the mobile ecosystem with respect to technological knowledge. The firms categorised as catch-up players have played a brokerage role within their group, while the firms categorised as knowledge keystone players play a brokerage role across different groups.  相似文献

This article investigates the key factors that determine the productivity performance of telecommunications services industry. A simple theoretical model is used to illustrate that the Total Factor Productivity (TFP) growth is attributable to the effects of scale economies, market competition and technical change. We then examine empirically the effect of various factors on the TFP growth in the industry using panel data in 12 Organization for Economic Co-operation and Development (OECD) countries for the period 1983 through 2003. The empirical results are consistent with the theoretical prediction. A new finding in this article is that higher machinery and equipment (M&E) capital intensity and human capital contribute to higher TFP growth in the telecommunications services industry. The decomposition analysis also suggests that technical change induced by changes in M&E capital intensity and human capital are important sources of productivity performance in the industry across the OECD countries, contributing to about 20–50% and 2–7% of TFP growth, respectively. These findings highlight the importance of improving the conditions for M&E capital investment and the quality of human capital, which in turn could facilitate the adoption of new technologies and enhance the productivity in the industry.  相似文献

Regulating former telecommunications monopolies has often been legally and technically complex. Among other options, incumbent operators were mandated to share, sell or split their infrastructure thus encouraging market entry. Given the importance of broadband technologies, competitive access has become a policy priority. We use data from 167 broadband markets over a period of 11 years. Firm and intra-platform competition on the incumbent’s legacy network (Digital Subscriber Line) accelerate adoption of broadband, whereas competition over different access technologies does not. The duration of the different regulatory effects shows that simpler network changes have a long-lasting yet delayed effect compared to technically demanding ones.  相似文献
