Liberalization of EU telecommunications and trade: theory, gravity equation analysis and policy implications

The liberalization of telecommunications has contributed to considerable price reductions in international telephony and to rising volumes of telecommunications. This raises the issue of the economic impact of international telephony. Falling international information and transaction costs should stimulate competition and enlarge the market radius for producers in the tradables sector—this lets us to expect trade creation effects of international telecommunications; this in turn should raise output provided that more intensive international telecommunications stimulates international diffusion of knowledge or brings about trade-related specialization gains. Based on a modified gravity equation which is taking into account the role of international telecommunication volumes—based on new ITU data—we show that international telephony has a significant positive impact on trade volume: A rise of the international telecommunications volume by 10% raises trade by 2% in Europe. At the same time the coefficients of the traditional variables, GDP in the exporting and the importing country, are smaller than in traditional approaches. Thus from a policy perspective the modernization and growth of the international telecommunications network—within a system of enhanced competition—is crucial for Europe: economic integration will be reinforced. From this perspective the Lisbon Agenda is right to emphasize the importance of creating a digitally networked knowledge society.

Telecommunications dynamics,output and employment

In EU countries, opening up of telecommunications markets and regulations have helped to reduce the price of digital services which is an important quasi-input factor in all firms. Integrating the use of telecommunications in a macroeconomic production function is the analytical starting point for our interdependent analysis of output, use of telecommunications and employment. Based on unit root and co-integration analysis as well as an error correction three-equation model which is estimated simultaneously, we present results both on long run links and short run links between telecommunications, output and employment. Considering various scenarios suggests that a fall in the relative price of telecommunications can generate a cumulated employment increase of 760,000 within seven years in Germany. The institutional setup for regulating telecommunications could be improved in Germany and other EU countries; investor-friendly regulation is required.     

It may be urgent,but is it important? A look at how employees evaluate their emails

This paper presents the results of a study designed to identify the cues employees use to identify an email as important and/or urgent. Taking an emic perspective, a qualitative research methodology is used to analyze interview responses from knowledge workers. Our findings support the notion that employees use strategies similar to those encapsulated in Mitchell et al.’s (1997) operationalization of stakeholder salience when evaluating an email's importance and/or urgency. Results from this study can be used to design email policies to support knowledge worker performance.     

Dispute resolution in international trade

Internationalization of a company's operations creates new uncertainty and risk for the company, including political and legal issues. This article discusses some of these problems, examines alternative solutions for these problems, and makes recommendations as to what solutions a company should give priorty to. Specifically, the study argues that in international business arbitration and litigation should be used as lust resort and only when all other alternatives have been exhausted.     

Current account sustainability in G7 and BRICS: Evidence from a long-memory model with structural breaks

In this paper, we extend the existing literature on current account sustainability by examining the relevance of long memory and structural breaks in modelling the dynamics of current account to gross domestic product (GDP) ratios in G7 and BRICS. Unlike standard unit root tests, which have low power, especially in cases where the series is characterized by a fractional process, the long-memory approach provides an exact measure of the degree of persistence. However, long-memory models are known to overestimate the degree of persistence of the series in the presence of structural breaks. We show that regime changes do exist in both the mean and trend of the current account to GDP ratios. Thus, we test persistence allowing for both smooth and sharp breaks. Our methodology also allows any number of sharp breaks, whereas standard unit root tests only permit either one or two breaks. Hence, our approach is more general and more robust to misspecifications caused by the omission of breaks than standard methods. We show that current accounts are sustainable in both groups of countries, with the G7 and South Africa displaying long-memory behaviour.     

Constant supervision of bathing in French public swimming pools: an unrealistic regulatory requirement?

In France, to prevent drowning accidents in public swimming pools (PSPs), bathing must be constantly supervised by qualified staff. However, fatal drowning regularly occurs in supervised aquatic facilities. A review of the literature shows that human supervision is a complex task. The aim of this research is to fully assess the periods during which supervision is not carried out, or carried out in an inadequate manner. The observations made in 108 French PSPs show that supervision is not carried out 18% of the time and that it is carried out inadequately 33% of the time. The medical literature shows that, in order to expect to survive without after-effects, an immersed victim requires intervention within a time limit of not more than three minutes; however, we noted, over a total observation time of 54 hours, 147 periods (29.8%) during which the supervision system was degraded for three minutes or more. This quantification research on the periods of degraded supervision is complemented by an identification of the causes leading to these degradations, from which we can draw interesting areas for improvement, particularly from an organizational point of view, in order to improve safety management in French PSPs.     

A choice‐theoretic analysis of a corporate tax holiday versus a subsidy

This paper attempts to compare the effect of a corporate tax holiday with that of a subsidy on the behaviour of the individual firm. Assuming the subsidy equals the amount of tax paid by a firm operating under the subsidy system, we find that the firm's net profit will be greater under the tax holiday than under the subsidy regime. Similarly, if the subsidy exceeds the tax by an amount that would equalize the profits made by the (“marginal”) firm under the two regimes, then it is found that firms with higher than “average” unit costs would opt for the subsidy system; conversely, firms with a low cost structure would maximize profits by selecting the tax holiday. Finally, a multiperiod analysis of the particular choice facing prospective manufacturers in Ciskei, shows that the firm would normally choose the subsidy system except if the current tax exceeded the subsidy at the output level representing maximum profit under the tax holiday.     

The influence of sponsor,servicer, and underwriter characteristics on RMBS performance

This paper assesses how the default frequencies of RMBS loan portfolios vary depending on sponsor, servicer, and underwriter characteristics. We find that the larger and healthier the sponsor of the transaction, the lower the default frequency of the securitized loans. This finding is consistent with the hypothesis that banks with a longer market perspective are less willing to risk their good reputation for a gain in short-term profits. More surprisingly, we find that there is a negative relationship between the market share of the lead underwriter and default frequency. In contrast to reputational capital theory, it appears that investment banks with high market shares in the securitization business exploit their reputational capital.
