Mobile voice diffusion and service competition: A system dynamic analysis of regulatory policy

Dynamic behavior in mobile telecommunications markets is often the result of interactions between market actors. As the structure and dynamic complexity of such interactions tend to be difficult to identify, it is challenging for regulators to anticipate the effects of their policy decisions. This article uses system dynamics to evaluate the effect of technology harmonization and mobile number portability policies on mobile voice diffusion and service competition. This is realized by first modeling the endogenous feedback structure resulting in dynamic behavior in the mobile telecommunications market and then by configuring the model for retrospective simulations of the Finnish market. Based on the retrospective simulations, the effect of technology harmonization and mobile number portability policy decisions is analyzed and the usefulness of system dynamics is demonstrated.

Competitive behavior in the European mobile telecommunications industry: Pioneers vs. followers

This paper studies the relationship between competitive strategy and improvement in the competitive position of pioneers and followers in the mobile telecommunications industry. The analysis uses a panel of data comprising all the actions of European firms operating in the digital mobile telecommunications industry with GSM 900 and/or DCS 1800 networks. The results show that competitors gain market share when they follow competitive strategies that are different from those of other firms. The paper also finds that price reduction actions represent the best approach for followers, while differentiation actions are the most effective strategy for pioneers.     

Municipal fiber in the United States: A financial assessment

Despite growing interest in broadband provided by municipally owned and operated fiber-to-the-home networks, the academic literature has yet to undertake a systematic assessment of these projects' financial performance. To fill this gap, we utilize municipalities' official reports to offer an empirical evaluation of the financial performance of every municipal fiber project in the U.S. operating in 2010 through 2019. An analysis of the actual performance of the resulting fifteen-project panel dataset reveals that none of the projects generated sufficient nominal cash flow in the short run to maintain solvency without infusions of additional cash from outside sources or debt relief. Similarly, 87% have not actually generated sufficient nominal cash flow to put them on track to achieve long-run solvency. In addition, 73% generated negative nominal cash flow over the past three fiscal years, leaving them poorly positioned to make up their deficits and causing them to fall farther into debt. An assessment based on the net present value of these projects' operating cash flow indicates that 53% of projects would not be on track to breakeven even assuming the theoretical best-case performance in terms of capital expenditures and debt service. Close analysis of these projects’ performance reveals that revenue generation likely plays a more important role in generating cash flow than efficiency in construction costs or operating efficiency.     

The Effects of Rate Regulation on Mean Returns and Non-Diversifiable Risk: The Case of Cable Television

Anticipated effects of rate controls are best observed in abnormalreturns in sectors providing complements and substitutes to the sector targeted for regulation. Further, risk may rise in response to rate controls, increasing the cost of capital and lowering investment. We examine stock price movements during events tied to the 1992 Cable Act, which reinstituted price controls on U.S. cable TV operators. We find strong evidence that controls were not anticipated to lower quality-adjusted cable rates. In addition, the uncertaintyof the policy led to substantially increased stock betas in some sectors.     

Telecommunications companies: One meeting with any competitor is enough to violate the EU's competition laws and result in fines

This commentary's purpose is to review how Telfort, T-Mobile, Vodafone, and others discovered that one “meeting” of any type with any telecommunications competitor could result in fines up to 10 percent of total “turnover” under EU competition law Regulation no. 1/2003, Article 23(2)(a), and to provide planning tips on how to eliminate the potential for those adverse consequences. While competition laws do not apply solely to the telecommunications industry, they do seem to affect it disproportionately. Telecommunications companies have global reach, and some of the most stringent competition law exists in Europe. Thus, all should review the most recent telecommunications ruling from the European Court of Justice, T-Mobile Netherlands BV v. Raad van bestuur van der Nederlandse Mededingingsautoriteit C-8/08 (2009). ¹ The ruling deals with whether the one meeting was “concerted activity” in violation of Article 81(1) EC.     

Inward Investment and Host Country Market Structure: The Case of the U.K.

Multinational enterprises are seen as vehicles for theinternational transfer of investment capital,protecting and increasing profits by transferringownership advantages across national boundaries. Assuch, the argument often follows that foreign directinvestment then exacerbates the monopoly problem inhost countries, by increasing concentration andfacilitating collusion. This paper however reveals thereverse, that inward investment into the U.K. acts toreduce concentration at the industry level, byincreasing competitive pressures on domesticindustry.     

Competitive Balance and Market Size in Major League Baseball: A Response to Baseball's Blue Ribbon Panel

Major League Baseball's recently convened Blue Ribbon Panel concluded that competitive balance had been reduced in the latter half of the 1990s. Specifically, the Blue Ribbon Panel argues that smaller-marketteams now know before theseason begins that there is little chance for post-season success. Such a finding is contrary to the findings of numerous economists who contend that Major League Baseball at the close of the twentieth century has never been more competitively balanced. The purpose of this work is to reconcile these disparate viewpoints via an analysis of the link between various definitions of market size and competitive balance. In general, our analysis of the 1990s reveals that market size, however it is defined, is not consistently related to the level of competitive balance in Major League Baseball.     

Antidumping and Production-Line Exit: The Case of the US Steel Industry

We present and examine a novel data set that contains production line information inside US steel plants. We exploit this highly disaggregated data to perform the first study of entry and exit behavior at the level of the production line within individual plants. Our empirical analysis reveals a number of interesting results. First, smaller production lines are more likely to shut down, as are lines that are owned by larger firms. Younger production lines and lines that have undergone modernization are more likely to survive. Our results indicate that lines that are operated by integrated producers are more likely to exit. We find no evidence, however, that antidumping decreases the likelihood of exit, despite the steel industry’s frequent use of antidumping protection.     

Market Power in International Commodity Trade: The Case of Coffee

This paper studies the impact of market power on international commodity prices. I use a standard oligopoly model and exploit historical variations in the structure of the international coffee bean market to assess the impact of a cartel treaty on coffee prices and its global welfare consequences. The results suggest that the International Coffee Agreement (ICA, 1965–89) raised its price by 75% above the Cournot‐competitive level, annually transferring approximately $12 billion from consumers to exporting countries, and its lapse in 1989 explains four‐fifths of the subsequent price decline, that is, the ‘coffee crisis.’     

Beyond the flat rate bias: The flexibility effect in tariff choice

Flat rates are a prominent pricing scheme for telecommunications services and are often preferred by consumers although average costs would be lower in an alternative usage-based tariff. Reasons are that flat rates protect against unexpectedly high costs (insurance effect), are more likely to be chosen if actual usage is overestimated (overestimation effect), and prevent any disutility that is associated with the immediate perception of marginal costs (taximeter effect). This study complements the literature on tariff biases by highlighting that a lack of tariff flexibility is a major impediment to choosing a flat rate: empirical support for this flexibility effect is found, while, at the same time, the insurance and overestimation effect that run in favor of flat rates are confirmed. Finally, the managerial implications of the findings for the introduction of the new cost cap tariff are discussed. The hybrid cost cap tariff can combine the flexibility and the insurance property, and may, therefore, exert a cost cap bias on consumers.     

Contested Resources: Unions,Employers, and the Adoption of New Work Practices in US and UK Telecommunications

The pattern of adoption of high‐performance work practices has been explained in terms of strategic contingency and in terms of union presence. We compare the post‐deregulation/privatization changes in work practice at AT&T, Bell Atlantic and British Telecom. On the basis of these cases, we argue that the choice of new work practices should be understood as a consequence not only of the company's resources or changes in its environment, nor of a simple union presence, but also as a consequence of the practices' effects on union power, the nature of the union's engagement, and the union's strategic choices.     

Assessment Inequity in a Declining Housing Market: The Case of Detroit

We examine the degree to which assessment practices in the City of Detroit have created substantial inequities in property tax payments across residential properties. Two key contributions of this article include: (1) inequities created by assessment practices are examined in a collapsed real estate market, and (2) quantile regression techniques are used to determine how assessment practices have altered assessment distributions within and across property value groups. Results show that current practices have created a wide range of property tax payments across properties with similar value (horizontal inequity), and similar tax payments for properties of differing values (vertical inequity).     

A tale of two reforms: Telecommunications reforms in Mexico

The telecommunications industry in most parts of the world experienced a round of market-led reforms in the early 1990s. After a period of sustained development in the sector numerous countries are moving toward government-led network deployments. Even though it may appear as if the pendulum swung back to the previous 1990s period of government-led development, this paper argues persistent regional disparities in access and adoption of new technologies generated a need for public action in the second reform. By analyzing the Mexican case and comparing the policy choices in each one of the reforms, this paper sheds light on how particular policy decisions in the first reform generated inefficient market solutions and were key in creating a perception of the need for stronger public action. In both reforms, the policymaking process was carried out by a small elite that negotiated its contents behind closed doors. Paradoxically, within the transition to democracy, in the second reform, the leaders of the major political parties established a closed-door agreement. Even though the 2013 telecommunications reform improved the status quo, it did not decrease market concentration and, once again, we face low levels of investment and high levels of digital exclusion. By reconstructing the policy decision process in each reform, this paper argues that the closed-door policy choices taken, which were the result of the interaction of political actors with their own agenda and interests, hampered the most efficient solutions.     

Effects of Transparency in Procurement Practices on Government Expenditure: A Case Study of Municipal Public Works

This paper examines the effect of improved transparency in the bidder qualification process, using the experience gained from a case study of municipal public works auctions. A difference-in-differences analysis reveals that improved transparency reduces procurement cost by up to 8%. This finding is robust with regard to the concerns of both endogeneity and sample selectivity. The bidding-function estimates, combined with features of Japanese procurement system, imply that the introduction of transparent practices is insufficient to bring about efficiency in public procurement.      

Market Share Instability and the Dynamics of Competition: a Panel Data Analysis of Japanese Manufacturing Industries

This paper explores market share instability as a measure of market mobility. Using a newly constructed panel data set, we examine the determinants of the market share instability of leading firms in Japanese manufacturing industries. The findings suggest that there is a significant relationship between concentration and market share instability, and the market shares of leading firms are more stable in highly concentrated industries. We also provide evidence that industry growth has a significantly positive effect on market share instability.     

Merger Simulation in the Presence of Large Choice Sets and Consumer Stockpiling: The Case of the Bottled Juice Industry

We simulate the price effects of several hypothetical mergers in the shelf-stable bottled juice industry. In doing so, we highlight the effects of consumer stockpiling on demand elasticity estimates and subsequent merger simulations. This task is complicated by a large number of choice alternatives within the bottled juice category. To address this challenge we employ a demand model based on the Distance Metric (DM) approach of Pinkse et al. (Econometrica 70:1111–1153, 2002). We find that merger simulations that do not account for consumer stockpiling behavior underestimate the permanent price changes that are likely to occur due to a merger.      

New Contractual Relationships in the Agency Worker Market: The Case of the UK's National Health Service

In recent years, there has been a trend towards the negotiation of closer contractual relationships between employers and employment agencies. However, little is known about this change or its likely consequences. In theory, such relationships can benefit employers by lowering fees and also reducing many of the hidden costs associated with the use of agency staff by improving the effectiveness of placement matching. Against this is the suggestion that formal partnerships are unlikely to have a positive impact given the uncertainty of demand for temporary labour and broader tendencies for risk displacement in buyer–supplier networks. In this article, our aim is to explore this matter focusing on recent developments in the UK's National Health Service. We find that new contractual relationships such as framework agreements and master vendor contracts are having mixed effects. While they serve to reduce direct costs for employers in the short term, this has been at the expense of relationship building and improvements in placement matching. These developments are also found to have some potentially negative consequences for the agency workforce itself.     

Telecommunications market structure in the USA: The effects of deregulation and divestiture

AT&T divestiture of its 22 operating companies in January 1984 ended the world's largest vertically integrated channel of telecommunications distribution. At the same time, customer premise equipment sales were deregulated in the USA by the FCC. This article explores the background policies which led to the changes, and examines the marketing opportunities which have arisen, together with likely future structural changes. The author concludes that the network will become more competitive and more responsive to customers' unique equipment needs.     

Telecommunications services in France: The regulated monopoly and the challenge of competition

Classical microeconomic modelling cannot alone explain the present trend of telecommunications deregulation. Based upon an examination of the French situation, the author argues that the current phenomenon should be viewed more as a game between three main players whose behaviour can be analysed using principles of industrial organization. The traditional telecommunications monopoly is bound to react defensively in response to increasingly powerful demand, stimulated by technical innovations, while at the same time the public policy maker searches for modern regulatory principles. Demand, as represented by large corporate customers, will probably trigger the next step in the game between the three players.
