The impact on broadband access to the Internet of the dual ownership of telephone and cable networks

In Portugal, until recently, the telecommunications incumbent offered broadband access to the Internet, both through digital subscriber line and cable modem. We estimate the impact on broadband access to the Internet of the structural separation of these two businesses. Using a panel of consumer level data and a random effects mixed logit model, we estimate the price elasticities of demand and the marginal costs of broadband access to the Internet. Based on these estimates, we simulate the effect of structural separation on prices and social welfare. Our estimates indicate that structural separation would cause a substantial welfare increase. These results raise questions about the policy of some countries of allowing the dual ownership of telephone and cable networks.     

The effect of subscriber line charges on residential telephone bills

This paper evaluates the way in which subscriber line charges (SLCs) have affected telephone company residential customers, comparing residential telephone bills before and after the $2.60 SLC began. Customer bills are analyses using the net bill reduction method and the consumer welfare method. Bills of low-income area and senior citizen customers are studied using a similar technique. The cumulative bill savings accruing to customers whose bills have been lowered for outweigh the small increases experienced by those whose bills are higher. Since the SLC programme began, interstate long-distance usage by low-income area customers has grown, on average, to nearly the same levels as usage for all residential customers.     

The moderating effect of environmental dynamism on the ownership and performance relationship

Agency theory posits a positive relationship between insider ownership and organizational performance. Past empirical studies examining this issue have not firmly established this relationship. The current study postulates and tests the moderating effect of environmental dynamism on the insider ownership and performance nexus. Implications and future research directions are considered. © 1998 John Wiley & Sons, Ltd.     

The effect of host country long term orientation on subsidiary ownership and survival

This paper examines the role which the long term orientation (LTO) dimension of host country culture plays in transforming multinational corporations’ (MNCs’) focus from transaction cost to transaction value in the context of MNC subsidiary ownership and survival. We used a sample of 10,236 overseas subsidiaries established by 1,291 Japanese MNCs in 29 host countries with varying levels of LTO to test our hypotheses. Results first showed that LTO has a direct positive effect on ownership levels. Second, we observed that there were positive interactions between LTO and cultural distance, and between LTO and geographic distance, on ownership levels. Third, we found that there were positive interactions between LTO and subsidiary ownership level, and between LTO and cultural distance, on subsidiary survival. The theoretical and practical implications of these findings are discussed in terms of the vital role LTO plays in determining whether transaction value or transaction cost considerations prevail in MNCs’ ownership strategies, and how MNCs can better take advantage of host country LTO and improve the survival likelihood of their subsidiaries.     

The effect of the Telefonica–BellSouth merger on the Argentine cellular telephone market

The aim of this paper is to evaluate the effects of the merger between Telefonica and BellSouth, which took place in December 2004, in the Argentine cellular telephone market. In this market the merger under analysis is horizontal. The evaluation is carried out by performing a demand estimation, using the PCAIDS model, and a marginal cost estimation, using supply prices and the elasticities inferred from the previously estimated demands. With those results, a merger simulation is run under different hypotheses related to possible marginal cost reductions. The merger is found to be able to lower supply prices for relatively small marginal cost reductions. This is basically due to the fact that the individual firms’ demands are highly elastic, and that the cross elasticity between the brands affected by the merger is relatively small.     

The structure of telephone tariffs

This paper compares the structure of telephone tariffs adopted by three types of organisation: government-owned systems responsible for both posts and telephones, government-owned systems responsible for telephones alone, and privately-owned telephone systems. It is found that privately-owned systems are significantly more likely to adopt three or more peak-load pricing periods. They are also more likely to differentiate tariffs by category of subscriber, and to offer lower rates for shared lines, but these differences are only significant if private telephone systems are compared with government systems responsible for both posts and telephones. Postal responsibility alone has little or no effect on these aspects of tariffs. The paper thus provides limited support for the view that ownership systematically affects behaviour.     

The influence of ownership on performance: An empirical study

This research examines the relationship between ownership structure and financial performance in the context of the agency theory. It improves upon previous research by presenting an improved risk-adjusted performance measure, by using a larger sample size than prior work and also by controlling for firm size differences. The results suggest that ownership is significantly related to firm financial performance even after controlling for size.     

The impact of intra-platform competition on broadband penetration

There has been an extensive debate about the role of broadband access regulation on market outcomes. This paper estimates the impact that the different modes of competition have had on broadband take-up to date, using a data set for EU27 countries. We find that ULL, which is one of main types of access-based competition in Europe, has had a positive impact on broadband take-up. However, the impact of ULL becomes smaller as its share increases. That is, ULL entry is less effective in areas where ULL take up is already high. Further, there is evidence of a crowding out effect between ULL and inter-platform competition. This means that ULL is less effective in enhancing broadband penetration in the areas where alternative networks already have a significant share of broadband lines.     

The structure of ownership and corporate acquisition strategies

In this study, we examine in an agency‐theoretic context the influence of executive equity stakes upon corporate strategy and firm value. We argue that beneficial, risk‐increasing corporate strategies may initially be emphasized but non‐value‐maximizing, risk‐reducing strategies may subsequently be emphasized as managers expand their stock ownership. We alternatively contend that stock options may have a consistently positive impact on firm risk taking and acquisition returns. The empirical findings are supportive of our expectations.

The role of the telephone in economic development

The author investigates the telephone's role as a contributory agent in economic development. Cross-sectional time series data for 60 nations over 13 years were used to determine how the telephone might make its contribution to economic development. Path analysis and cross-lagged correlation techniques indicate that the telephone does contribute to economic development. This contribution appears to come from the telephone's support of the organization of economic activity.     

The effects of CEO equity ownership and firm diversification on risk taking

This research explores the effects of CEO equity ownership and corporate diversification on firms' risk‐taking and risk avoidance behaviors. Hypotheses regarding these effects are tested through econometric analysis of mergers in the U.S. cable television industry. Risk taking and avoidance are measured as horizontal expansion through acquisitions and as the divestiture of assets, respectively, in the face of increasing environmental turbulence.

The impact of internationalization on performance and innovation: The moderating effects of ownership concentration

Researchers in international business have long been interested in understanding the impact of internationalization on performance and innovation. However, prior studies of this research stream offer mixed results. This study contributes to this research stream by employing agency theory to investigate how ownership concentration affects the performance and innovation implications of internationalization. Specifically, we examine two primary effects of ownership concentration: the incentive alignment effect, proxied by the controlling shareholder??s cash flow rights, and the entrenchment effect, proxied by the divergence between control rights and cash flow rights of the controlling shareholder. Based on a sample of Taiwan??s publicly listed firms, we find that the incentive alignment effect moderates the relation between internationalization and performance and innovation positively and the entrenchment effect moderates the relation negatively. These findings shed light on the mixed results of the literature. In addition, most countries outside the United States and the United Kingdom have high ownership concentration; therefore, our results may be generalizable to other settings, providing insight into the role of corporate governance in internationalization.     

The imbalances of telephone traffic for the United States

The US posts a large and growing deficit in international telephone services, a phenomenon often blamed on the accounting rate system. Using data for international calls between the US and 148 foreign destinations between 1991 and 1997, this paper finds that the increasing payment deficit for the US is associated with decreasing accounting rates. In other words, the international revenue settlement is related more to imbalances in telephone traffic than to accounting rates. The econometric model shows that growing asymmetries in teledensity, market concentration, and income levels between the US and the rest of the world explain the imbalances. Therefore, the appropriate solution to the payment deficit in telephone services is to focus on long-term economic factors that determine the flow of traffic.

Duopoly and competition: The case of American cellular telephone

The designation of local duopoly mar ket structure for the American cellular telephone industry offers an unusual opportunity to observe the relationship of duopoly and market performance. A study of the first 28 markets to offer cellular service in the United States found that forms of competitive behav iour were evident in every market, but the intensity of competition varied widely. In nearly every market, prices declined during the six-year period. Although duopoly appears to have facil itated price competition, the wide vari ation in performance from market to market indicates that factors other than market structure strongly influence the behaviour of the firm.     

The effects of ownership structure on conditions at the top: The case of CEO pay raises

We examine how ownership configuration affects the determination of CEO pay raises. Based on a sample of 188 firms over a 5-year period, it was found that pay raises were based on distinctly different factors, depending on the ownership profile of the firm. In management-controlled firms—where no single major owner exists—results suggest an overarching pay philosophy: maximize CEO pay, subject to demonstration of face legitimacy of that pay. In externally-controlled firms—where a major (nonmanager) owner exists—results suggest a very different philosophy: minimize CEO pay, subject to the ability to attract/retain a satisfactory CEO.     

The effects of funding source and management ownership on the productivity of R&D

This study investigates the influence of the source of R&D funds and management ownership on R&D productivity. The lagged effect of the source of R&D funds on R&D output is investigated for a sample of US manufacturing firms in five industries over the 1996–99 period. Estimates based on 779 firm-years show that R&D productivity increases with the proportion of stock held by managers and directors of firms primarily in the Other Electronics industry. The estimates also show that recipients of government-sponsored R&D funds in the Chemicals industry have lower levels of output (sales) for each dollar committed to R&D. In addition, output for firms in the Chemicals industry worsens as management stockholding increases, implying an agency cost rationale for the observed difference in output. The implication is that firms with high manager-owner content are less productive with government-sponsored R&D than with company-financed R&D. The reported results suggest that potential agency costs should be incorporated in government-sponsored R&D contracts. It also suggests that the source of R&D funds should be disclosed and incorporated into the valuation of intangible assets attributable to research and development.     

The effects of ownership concentration and corporate debt on corporate divestitures in Chinese listed firms

This study examines how ownership concentration and corporate debt impact corporate divestitures in China. Corporate divestitures reduce the asset base of a company and the opportunity for expropriation by majority shareholders. In emerging economies, weak legal institutions, combined with equity ownership concentration and high corporate debt, allow majority shareholders to avoid such disciplines. Consequently, the relationship between these governance mechanisms and divestiture activity exhibits a pattern that is different from that in developed economies. Using archival data collected from 1,210 Chinese listed companies during 1999–2003, we found that ownership concentration by the largest shareholder depressed corporate divestitures both in state-controlled and in non-state-controlled firms. The negative effect of corporate debt on divestitures only existed for state-controlled firms. Our finding provides corroborating evidence for principal–principal conflicts in emerging economies. It suggests that corporate strategy in these countries can be better explained by taking into account the unique agency problems that are prevalent in these economies.

The consumer loss of the minimum duration for mobile telephone calls

This article estimates price elasticities of demand for the duration of mobile telephone calls for Portugal, as well as the monetary loss per consumer of the existence of a minimum duration of calls. The demand for the duration of calls is estimated using a Tobit model for panel data with individual random effects. The elasticity of demand is found to be small and to vary across firms. At current prices, the average duration of calls ranges between 101 and 109 s, while the estimated average length of calls without minimum duration ranges between 63 and 66 s. Hence, the existence of a minimum duration for calls results in a monetary loss of 35–40% of the average invoice.
