ABSTRACT

We undertook a review and classification of research on electronic commerce (e-commerce) in developing countries. We analyzed 181 articles published in a broad range of journals covering e-commerce, global information technology, and development issues. The analysis provides a roadmap that not only indicates the current state of e-commerce for development research but also identifies gaps and priorities for future research. This will be of significant value to both academics and practitioners who are working on, or plan to work on, e-commerce in developing countries.  相似文献

The study analyzes the impact of advertising, goodwill, and other intangibles on investor returns in the consumer packaged food and beverage industry during 2008–2012, a timeframe during which smaller brands wrestled $18 billion in sales away from large manufacturers of processed foods. The findings demonstrate that those firms that were able to allocate a greater percentage of their revenue to their ongoing advertising efforts were able to enhance investor holding period returns (HPR). In addition, those firms with a higher ratio of intangible assets other than goodwill to total assets were also able to enhance HPR. However, there was not a significant positive relationship between the ratio of acquired goodwill to total assets and HPR. Hence, packaged food and beverage manufacturers are advised to seek competitive advantages through their own brand-building efforts rather than seeking to enhance investor returns through a strategy based on company mergers and acquisitions.  相似文献

This study examines whether foreign direct investment (FDI) inflow helps or hinders local firms’ uptake of corporate social responsibility (CSR) activities in a developing host country. The study further examines the interaction effect of host institutions on the relationship between FDI inflow and local firms’ uptake of CSR activities. Results of hierarchical regression analysis of data from a sample of 227 local firms in Ghana, reveal that local firms’ uptake of CSR improves significantly with an increasing inflow of FDI through knowledge transfer. Host institutions are also found to influence the transfer of CSR activities from foreign firms to local firms. However, when the quality of institutions is very high, the impact of FDI on local firms’ CSR activities diminishes. Research and practical implications of these findings are discussed. © 2015 Wiley Periodicals, Inc.  相似文献

We revisit the assertion that entrepreneurs are uniquely characterized in their ways of thinking; specifically being relatively more prone to the overconfidence bias and the representativeness heuristic in their decision‐making. We replicate an earlier seminal study in entrepreneurial cognition, with a wider and more current survey. We then extend that analysis by investigating whether such “different thinking” leads to different (i.e., less rational) choices and different (i.e., worse) firm performance. Given the expected differences, we also investigate whether there exist other factors that affect the use of such biases and heuristics, to control their effects on focal outcomes.  相似文献

This study examines the critical role of perceived effectiveness of the Marketing function (MF) in small and medium‐sized enterprises (SMEs) in leveraging entrepreneurial network ties to improve strategic adaptiveness (SA). The study tests whether a MF perceived as effective by SMEs’ managers/owners moderates the relationship between SMEs network ties and SA required for improved performance. Findings of a moderated regression analysis on a sample of 263 Croatian SMEs indicate that network ties contribute significantly to their SA, and that a MF perceived as effective only moderates the impact of customer and competitor ties on SMEs’ SA. Research and practical implications are discussed.  相似文献

Using design and communication principles, this study uses a content analysis design to evaluate all active blogs from the 2011 Fortune 500 list (n = 125). The results indicate that corporate America has only modestly incorporated the dialogic principles into their blogs. Current corporate blogs are well-designed as far as making them searchable and easy to navigate; however, the blogs are mostly being used to provide information in a one-way manner rather than creating an open dialogue with consumers. While blogging can enhance relationships with stakeholders, corporate communicators must strive to develop legitimate conversations with their blog readers.  相似文献

One of directors’ key fiduciary duties is to set the firm’s direction and then vet the strategy proposed by the CEO. Despite this, McKinsey reports that the majority of directors feel they do not understand their firm’s strategy, and even if they do understand it, they do not feel they have the desired impact on their firm’s strategy. This article argues that this shortfall stems from a failure to cross the chasm between CEOs and directors. We propose a framework to bridge this gap and assist board members to better understand and vet their firm’s strategy.  相似文献

Despite the benefits of walking as a means of travelling, walking can be quite hazardous. Pedestrian-vehicle crashes remain a major concern in Ghana as they account for the highest percentage of fatalities. The objective of this study is to determine the effect of both natural and built environmental features on pedestrian-vehicle crash severity in Ghana. The study is based on an extensive pedestrian-vehicle crash dataset extracted from the National Road Traffic Accident Database at the Building and Road Research Institute (BRRI) of the Council for Scientific and Industrial Research (CSIR), Ghana. Using a multinomial logit modelling framework, possible determinants of pedestrian-vehicle crash severity were identified. The study found that fatal crashes are likely to occur during unclear weather conditions, on weekends, at night time where there are no lights, on curved and inclined roads, on untarred roads, at mid-blocks and on wider roads. The developed model and its interpretations will make important contributions to road crash analysis and prevention in Ghana with the possibility of extension to other developing countries. These contributing factors could inform policy makers on road design and operational improvements.  相似文献

An information approach to international currencies   总被引:1,自引:0,他引:1  
Models of currency competition focus on the 5% of trading attributable to balance-of-payments flows. We introduce an information approach that focuses on the other 95%. Important departures from traditional models arise when transactions convey information. First, prices reveal different information depending on whether trades are direct or though vehicle currencies. Second, missing markets arise due to insufficiently symmetric information, rather than insufficient transactions scale. Third, the indeterminacy of equilibrium that arises in traditional models is resolved: currency trade patterns no longer concentrate arbitrarily on market size. Empirically, we provide a first analysis of transactions across a full market triangle: the euro, yen and US dollar. The estimated transaction effects on prices support the information approach.  相似文献
