Telecommunications and economic growth: an empirical analysis of sub-saharan Africa

We examine the effect on economic growth of mobile cellular phones in sub-Saharan Africa where a marked asymmetry is present between land-line penetration and mobile telecommunications expansion. This study extends previous ones along two important dimensions. First, we allow for the potential endogeneity between economic growth and telecommunications expansion by employing a special linear generalized method of moments (GMM) estimator. Second, we explicitly model for varying degrees of substitutability between mobile cellular and land-line telephony, so that greater expansion of mobile telecommunications can have a different impact whenever the level of land-line penetration differs. We find that mobile cellular phone expansion is an important determinant of the rate of economic growth in Sub-Saharan Africa. Moreover, we find that the contribution of mobile cellular phones to economic growth has been growing in importance in the region, and that the marginal impact of mobile telecommunication services is even greater wherever land-line phones are rare. Given the low cost of mobile telecommunications technology relative to other broad infrastructure projects, especially land-line infrastructure, we advocate that mobile telecommunication services be encouraged in the area.

Futures basis, inventory and commodity price volatility: an empirical analysis

We employ a large dataset of physical inventory data on 21 different commodities for the period 1993–2011 to empirically analyze the behavior of commodity prices and their volatility as predicted by the theory of storage. We examine two main issues. First, we analyze the relationship between inventory and the shape of the forward curve. Low (high) inventory is associated with forward curves in backwardation (contango), as the theory of storage predicts. Second, we show that price volatility is a decreasing function of inventory for the majority of commodities in our sample. This effect is more pronounced in backwardated markets. Our findings are robust with respect to alternative inventory measures and over the recent commodity price boom.

Responding to the EU Emissions Trading Scheme: an empirical analysis of corporate carbon disclosure strategy

The purpose of this paper is to explore how companies that hold carbon trading accounts under European Union Emissions Trading Scheme (EU ETS) respond to the climate change by using disclosures on carbon emissions as a means to generate legitimacy compared to others. The study is based on disclosures made in annual reports and stand-alone sustainability reports of UK listed companies from 2001- 2012. The study uses content analysis to capture both the quality and volume of the carbon disclosures. The results show that there is a significant increase in both the quality and volume of the carbon disclosures after the launch of EU ETS. Companies with carbon trading accounts provide greater detailed disclosures as compared to the others without an account. We also find that company size is positively correlated with the disclosures while the association with the industry produces an inconclusive result.

Do IMF and World Bank programs induce government crises? an empirical analysis

We examine whether and under what circumstances World Bank and International Monetary Fund (IMF) programs affect the likelihood of major government crises. We find that crises are, on average, more likely as a consequence of World Bank programs. We also find that governments face an increasing risk of entering a crisis when they remain under an IMF or World Bank arrangement once the economy's performance improves. The international financial institution's (IFI) scapegoat function thus seems to lose its value when the need for financial support is less urgent. While the probability of a crisis increases when a government turns to the IFIs, programs inherited by preceding governments do not affect the probability of a crisis. This is in line with two interpretations. First, the conclusion of IFI programs can signal the government's incompetence, and second, governments that inherit programs might be less likely to implement program conditions agreed to by their predecessors.

Empirical analysis of the Lieb-Oxford bound in ions and molecules

Universal properties of the Coulomb interaction energy apply to all many-electron systems. Bounds on the exchange-correlation energy, in particular, are important for the construction of improved density functionals. Here we investigate one such universal property-the Lieb-Oxford lower bound-for ionic and molecular systems. In recent work [J Chem Phys 127, 054106 (2007)], we observed that for atoms and electron liquids this bound may be substantially tightened. Calculations for a few ions and molecules suggested the same tendency, but were not conclusive due to the small number of systems considered. Here we extend that analysis to many different families of ions and molecules, and find that for these, too, the bound can be empirically tightened by a similar margin as for atoms and electron liquids. Tightening the Lieb-Oxford bound will have consequences for the performance of various approximate exchange-correlation functionals. (C) 2008 Wiley Periodicals Inc.

The Relationship between Transport Infrastructure and EconomicGrowth: An Empirical Analysis Comparing Developing and DevelopedCountries

Gross domestic product (GDP) is generally considered as the most important index and comprehensive measure of the size of economy. This paper investigates empirically the relationship between transport infrastructure (focus on highways) and GDP growth based on a production function approach. The physical stocks of transport infrastructure were used instead of monetary data to measure public capital together with several other variables (labor and private capital) that were hypothesized to affect economic growth. Then we explore a number of subsequent studies that use panel data covering the period between 1992 and 2004. An investigation was done to compare developed countries and developing countries. Results indicate that physical units are positively and significantly related to economic growth. Furthermore there was an interesting finding that the output elasticity with respect to physical units for developed countries is higher than developing countries.

An empirical analysis of gender differences in sports attendance motives

In Australia, male sports attendees outnumber female sports attendees by 25%, yet little research has been conducted into the attendance motives of women. This study undertakes an analysis of 460 respondents using descriptive and multivariate statistics to distinguish the attendance motivations of women and compare them directly to those of male attendees. The findings suggest that female attendance can be influenced through management and promotional strategies.

Antecedents of recommending infrequently purchased services: a conceptualisation and an empirical analysis

This project aimed to conceptualise and analyse empirically the antecedents of word-of-mouth in the context of an infrequently purchased service (tourism special events). The relationships examined included those between involvement, past experience, overall satisfaction, interest in attending next time, likelihood of attending next time, and the likelihood of recommending to others that they attend the event. There was some support for the overall model, in that the regressing of likelihood of recommending on the other variables produced an equation containing measures of most of the key variables, viz., revisit intention, satisfaction, revisit interest, and involvement. However, involvement appeared to operate in the opposite direction to that hypothesised.

Marketing position taxonomies : an empirical analysis

Despite the continuing need for an empirically validated classification of marketing positions, for theoretical and practical purposes, it appears that no such schema exists. This study contributes to the development of such a taxonomy through an empirical examination of marketing positions. Specifically, the research extends an existing taxonomy by empirically investigating personal selling marketing activities. Based on the taxonomy developed by Darmon (1998), data were collected about the information load, information complexity, and time and relationship management activities of marketers. Various analytical techniques were used to investigate specific features of the instrument and the taxonomy, as well as to provide convergence for the conclusions drawn by the researchers. It was established that sales positions can be more meaningfully identified, and, therefore, better categorised, by six dimensions than by job title or job role. Further, it appears that marketers in the same selling position vary significantly on these dimensions. These findings have important implications for marketing theory, applied research and management. However, future research should refine the instrument used in this study, since some anomalies emerged in the findings, and extend the study by investigating a wider range of marketing positions. Such research may also explore whether the dimensions identified in this study influence the performance and job satisfaction of marketers, and the extent to which marketing managers account for these variations.

Career orientations of marketing employees : an empirical analysis

There is a distinct gap in research in marketing in relation to understanding the role of marketing employees in organisational marketing performance, in contrast to the usual focus on identifying the contribution of successfully completing marketing tasks in the pursuit of organisational marketing objectives. The major exception to this has been research related to sales personnel, as a subset of all marketing personnel, but even this has usually been from a sales management perspective and not principally from the viewpoint of individual employees. The current study explored the career orientations of marketing employees in relation to the demographic profile and other work-related characteristics of marketing employees. Operationalised by Schein's (1990) Career Orientations Inventory, the 'internal career' of 78 marketing employees at the Australian headquarters of a major multinational manufacturing firm was examined. Sample means indicated that 'Lifestyle', 'Technical Functionality', and 'Pure Challenge' were the dominant career orientations, but a 'General Managerial' orientation also emerged as important, when individual 'Career Anchors' were examined. An 'Entrepreneurial' anchor was found to be the least dominant of the eight anchors measured, which may be seen as somewhat surprising for Marketing employees. Significant relationships were found between some demographic variables and the dominant career orientations, but overall, career orientation tended to be unrelated to the demographic variables. Future research will examine the relationships between employee career orientation and individual position, and marketing productivity.

The MORTN market orientation instrument - an empirical analysis

This paper focuses on Deshpande and Farley's (1998) MORTN market orientation instrument. Specifically, the paper investigates empirically the factor structure and reliability of the supposedly unidimensional instrument. When the MORTN instrument was tested utilising Australian organisations, a two-dimensional factor structure was found to fit the data more acceptably then the unidimensional structure proposed by Deshpande and Farley. These dimensions may be characterised as being Customer/Market Intelligence (Dimension One) and Customer Service (Dimension Two).
