Modelling multinational telecommunications demand with limited data

Forecasting the diffusion of innovations in the telecommunications sector is a constantly recurring problem for national providers. The problem is characterised by short data series making the estimation of model parameters unreliable. However, the same innovation will be diffusing simultaneously in other national markets, although with a different start date. The use of this cross-sectional data in constructing innovation diffusion models is investigated here. Four models for pooling the cross-sectional data are described and two diffusion models are discussed although only one, the Gompertz model is used throughout. Three innovation data sets are used in the evaluation of the models: digital cellular telephones, ISDN connections and fax connections. The pooled diffusion forecasts proved to be more accurate in several comparisons relative to a naïve benchmark and to individual forecasts when available.     

The spatial externalities of car-based worktravel emissions in greater London, 1981 and 1991

This research considers vehicle emissions from travel to work trips by car within and through the localities of London. Specific focus is placed on the residential origins of the trips and the analysis is based on 1981 and 1991 Census travel to work data. London is divided into some 24 one kilometre concentric ring bands and the number of vehicle kilometres travelled within each of these is calculated from ward to ward origin-destination worktravel movements by car. The spatial distribution of vehicle emissions from the perspective of the source origin of this type of urban environmental external disbenefit is derived. The research points to the highest concentrations of emissions located firmly in the centre of the city and this confirms scientific survey evidence of air quality. The results also confirm that in Central and Inner London the largest proportionate contribution to total emissions arises from vehicles originating from residences in Outer London.     

Discount Rates in Disarray: Evidence on Flawed Goodwill Impairment Testing

Discount rate selection represents a centrally material factor impacting valuation models. Given the strong reliance on discounted cash flow modelling as a basis for determining an asset's recoverable amount, the judgement exercised by reporting entities regarding rate selection is of paramount importance in influencing the outcomes of the impairment testing process conducted under International Financial Reporting Standards (IFRS). The discretion surrounding rate selection could be used opportunistically to avoid or manage the timing of impairment losses to the detriment of transparency, comparability and decision usefulness. This study provides evidence consistent with the opportunism on the part of financial statement preparers, by demonstrating the existence of variances between independently generated risk‐adjusted discount rates and those disclosed as having been used by a sample of large listed Australian companies.     

Customer satisfaction measurement and management: A processual analysis

Customer satisfaction (CS) measurement has been widely advocated as central to the pursuit of market orientation, total quality management, and competitive advantage by allowing management to monitor and improve performance in the terms most significant to customers. However, relatively little analytical attention has been devoted to the processual issues implicit in the adoption of CS measurement systems by organizations. This paper presents executive workshop data and new survey evidence to support the contention that both research and managerial agenda should be extended to recognize the multi‐dimensionality of organizational process, and the implications of that characteristic for the adoption and use of CS measurement systems.     

Barriers to Marketing Development in the Barristers’ Profession

This paper focuses on the marketing of professional services, and on the very specific context of barristers in the British legal professions. We examine the background provided by this sector of professional services, and then present the results of a set of qualitative investigations into the role of marketing as it is perceived by members of this profession, and identify a series of perceived by members of this profession, and identify a series of considering the implications of our findings for how marketing concepts can be productively employed in this area of activity and the needs for conceptual as well as practical extension, but remain largely pessimistic about the current prospects for extending marketing activities into the area of barristers’ marketing.     

Commentary: Some Further Evidence on Discount Rate Selection in the Context of Goodwill Impairment Testing

In an earlier edition of this journal, we published evidence relating to the nature of discount rates chosen by a sample of large Australian‐listed firms in the context of their goodwill impairment testing ( Carlin and Finch 2009 ). We argued that our evidence suggested that the rigour of the International Financial Reporting Standards (IFRS) goodwill impairment testing process was being undermined by inappropriate choice of discount rates on the part of many firms. In a commentary published alongside our article, questions were raised as to the validity of our conclusions and the methodology we applied in our study ( Gallery 2009 ). Subsequently, Bradbury has also contributed to the debate, raising similar concerns to those voiced by Gallery ( Bradbury 2010 ). In this brief paper, we provide further and better particulars in relation to our original dataset in a bid to assist those who have taken an interest in this debate to further inform their view of the merits (or otherwise) of the case we made in our original article.     

Using Signals to Initiate Importer-Exporter Relationships: Evidence from Vietnamese Importers

ABSTRACT

Purpose: Realizing the existence of information asymmetry in export markets and the use of signals to distinguish high-qualified sellers from low-qualified sellers, this study investigates the effects of signal consistency and signal clarity on exporter credibility, and subsequently, importer relationship intention.

Methodology: Using a survey data set collected from a systematic sample of 418 Vietnamese importers, the authors tested a model hypothesizing the impact of signal consistency and signal clarity on exporter credibility, and subsequently, on importer relationship intention.

Findings: The authors found that signal consistency and clarity have a positive impact on exporter credibility. Signal consistency also enhances the level of signal clarity. They also found that exporter credibility underlies importer relationship intension.

Research Implications: Under the condition of information asymmetry, importers face difficulties in identifying and evaluating the best supplier among available suppliers in order to make the most appropriate selection decision. The findings confirm that signal clarity and consistency can help exporters to overcome such problems. Exporters should ensure that all signals sent to importers are clear and consistent over time to encourage importers to build long-term business relationships with them.

Contributions: The findings of this study add to the literature on signaling in exporter–importer relationships and can serve as an initiation for further research in the area in transitioning economies.
