This paper examines microfinance intervention in rural poverty reduction in Ghana by surveying 100 rural women farmer-entrepreneurs. The findings reveal that microfinance interventions that emphasize both credit provision and social intermediation improve access to credit, improve business performance, and contribute to a higher standard of living for female farmer-entrepreneurs and their families. The results show that the microfinance scheme has been successful due to a strong social network and group relationships among the farmers. An implication of the study is that poverty reduction programs in developing countries need to emphasize social and human development components in microfinancing policies.  相似文献

In recent years, significant attention has been directed toward the fifth generation of wireless broadband connectivity known as ‘5G’, currently being deployed by Mobile Network Operators. Surprisingly, there has been considerably less attention paid to ‘Wi-Fi 6’, the new IEEE 802.1ax standard in the family of Wireless Local Area Network technologies with features targeting private, edge-networks. This paper revisits the suitability of cellular and Wi-Fi in delivering high-speed wireless Internet connectivity. Both technologies aspire to deliver significantly enhanced performance, enabling each to deliver much faster wireless broadband connectivity, and provide further support for the Internet of Things and Machine-to-Machine communications, positioning the two technologies as technical substitutes in many usage scenarios. We conclude that both are likely to play important roles in the future, and simultaneously serve as competitors and complements. We anticipate that 5G will remain the preferred technology for wide-area coverage, while Wi-Fi 6 will remain the preferred technology for indoor use, thanks to its much lower deployment costs. However, the traditional boundaries that differentiated earlier generations of cellular and Wi-Fi are blurring. Proponents of one technology may argue for the benefits of their chosen technology displacing the other, requesting regulatory policies that would serve to tilt the marketplace in their favour. We believe such efforts need to be resisted, and that both technologies have important roles to play in the marketplace, based on the needs of heterogeneous use cases. Both technologies should contribute to achieving the goal of providing affordable, reliable, and ubiquitously available high-capacity wireless broadband connectivity.  相似文献

Manufacturers in many industries seek service-led growth beyond their product core. Yet research on the link between service revenue growth and firm profitability is still at an early stage. To shed further light on this complex relationship, we report the results of a longitudinal study based on panel data of 414 companies in the German mechanical engineering industry collected over a five-year period. Employing latent growth curve modeling and using multiple group analysis, the study provides empirical evidence for the causality between service infusion strategies and manufacturers' profit trajectories. The results also reveal differential effects of service categories and the moderating role of manufacturers' product innovation efforts. For companies with high product innovation activity, services supporting the product (SSPs) directly increase firm profitability, while services supporting the clients' actions (SSCs) do not display any link with long-term profitability. Conversely, for companies with low product innovation activity, SSCs have a significant, positive effect on firm profitability, while SSPs have only an indirect effect. In sum, our findings caution managers that service offerings do not automatically improve company profits. Manufacturers must carefully consider the fit between their service offerings and product innovation activities to grow bottom line results.  相似文献

While the creation of superior customer value is regarded as fundamental to a firm's long-term survival and growth, little is known about the effective implementation of a firm's value orientation at sales force level. As the sales force plays a pivotal role in implementing marketing strategies, this study adopts a discovery oriented approach and conceptualizes value-based selling as an effective sales approach in business markets. Based on in-depth interviews with sales managers in a variety of industries, we identify and portray three salient dimensions of value-based selling, namely (1) understanding the customer's business model, (2) crafting the value proposition, and (3) communicating customer value. The selling behavior entails a mutual orientation and focuses on the value-in-use potential of the offering for the customer's business profits. We argue that value-based selling is a unique concept that differs from the established selling approaches and propose a conceptual model linking value-based selling to performance outcomes. To further advance our knowledge about the effective implementation of a firm's value orientation, we identify future research avenues embracing qualitative and quantitative research methodologies.  相似文献

In 2012, Azerbaijan hosted the Eurovision Song Contest. For this emerging tourism-oriented country, the cultural mega-event represented a unique opportunity to present itself to a broad international public and construct a positive country image. The present longitudinal study explores how consumer images of Azerbaijan as a country were formed and changed as a result of the nation’s hosting of this event. By measuring the same respondents’ country image evaluations before and after the event, the present findings shed light on consumers’ processes of country-image formation and illuminate the event’s impact on Azerbaijan’s country image.  相似文献

This article examines the origins, dimensions and implications of Africa's crisis. It draws attention to the impact of historical experiences, the distortions and disarticulations of that experience, and to the coalitions, contradictions, crises and conflicts inherited at independence. It looks at postcolonial alignment and realignment of social and political forces, the crisis of accumulation and power, and the implications of the region's marginal location and role in the global division of labour and power. Calling for a need to transcend the manifestations of the African predicament, the article looks at regional and international responses to the crisis. It concludes by prescribing the need for a fundamental political restructuring, the empowerment of the people and their communities and organizations, a socially sensitive structural adjustment programme, and the recomposition of the content and context of politics and social relations.  相似文献

Does environmental purchasing and supplier management (EPSM) help to reduce greenhouse gas (GHG) emissions in the supply chain and, thereby, mitigate climate change? And, if so, under which conditions? Taking these two questions as a starting point, we hypothesize that heightened environmental protection efforts targeting the upstream value chain should lead to a reduction of greenhouse gas emissions in the buying companies' supply chain. We continue to delineate three contingency factors that might affect the relationship between EPSM and supply chain GHG emissions: The power of the buying firm over supply chain partners, prior experience in EPSM, and materiality of environmental supply chain management in a certain industry. We collect longitudinal data from 260 companies and analyze them using hybrid panel data analysis. We find that the increase of EPSM leads to a significant reduction of the GHG emission intensity of buying firms’ supply chains and that this reduction is stronger for companies operating in industries where emission management is more material.  相似文献

The patent system underpins the business model of some of the fastest-growing companies. Used appropriately, it should support frontier technologies and nurture new firms. Used perniciously, it can stifle innovation and protect established technological behemoths. We analyze patent examination decisions at the American, European, Japanese, Korean, and Chinese patent offices and find evidence that patent attorneys have a surprisingly significant role in the patent system. Our results suggest that some forces within the examination system maintain the uneven playing field by allocating monopoly rights to inventors with better access to influential attorneys, rather than leveling it by favoring inventors with better, nonobvious ideas. Attorney quality is most important, vis-à-vis invention quality, in less codified and more rapidly changing technology areas such as software and ICT.  相似文献

Episodes of currency crises in Ghana over the recent past were examined. We also address two fundamental questions using VAR framework. First, how does fiscal policy relate to exchange market pressures (EMPs) in Ghana? Second, whether persistent fiscal slippages hinder the effective use of interest rate as monetary policy tool to influence undesirable exchange rate fluctuations? We found sterilization interventions to be more effective than interest rate as a monetary policy tool in moderating tensions in foreign exchange market. Higher recurrent expenditure was generally associated with higher EMP, while capital expenditures tend to assuage EMP. We recommend strong policy coordination between the fiscal and monetary authorities to ensure macroeconomic stability.  相似文献
