Global sourcing strategy and sustainable competitive advantage 总被引:1,自引:0,他引:1

Global sourcing strategy has been one of the most hotly debated management trends in the last 20 years. In its early years, global sourcing was examined mostly from “in-house” development and procurement perspectives; and in the last several years, research focus has shifted to “outsourcing” activities. Along with this shift from internal to external focus on global sourcing, many researchers and business practitioners have applied a core competency argument to justify increased levels of outsourcing activities on a global basis. Although the beneficial aspects of outsourcing are assumed in most cases, no consensus exists in reality as to the effect of outsourcing. Furthermore, the increased instability of the exchange rate environment in the last several years has also led to increased difficulties in managing globally scattered operations that were once fashionable in the 1980s-90s under the rubric of global strategy. In this article, the authors explore potential limitations and negative consequences of outsourcing strategy on a global scale. 相似文献

The challenge of developing and maintaining an effective organisation is intimately linked with HR activities that include selecting and motivating employees. Many organisations engage in an internal selection process designed to fill upper level positions with employees who have proven their worth at a lower level in the organisation. However, some observers have questioned whether this approach actually results in optimal individual and organisational performance. Using the Peter Principle as a starting point, this article examines the evidence for problems with merit‐based promotions, as well as various explanations that have been advanced for why these problems occur. This article then proposes a new model, based on contemporary management theory and evidence, which addresses the question of why promotions fail. 相似文献

The UK Brexit vote triggered a new wave of policy developments for a future outside the EU. In this context, we analyse the business performance of English hill and upland farms, characterised by marginal economic conditions but also high nature value (HNV). The analysis aims to help identify farm-level management and policy options for greater economic, environmental and social sustainability. Business performance is measured as technical efficiency and the occurrence and persistence of abnormal profits, estimated through stochastic frontier analysis and static and dynamic panel-data methods. The results help indicate rationales for recent trends including farm enlargement, farm family diversification, and agri-environment scheme entry. The single farm payment is found to be negatively associated with farm technical efficiency while agri-environmental subsidies were positively associated to short-term farm profitability. Farm adaptation and resilience during a period of likely turbulence in external circumstances is discussed in light of these findings, as well as potential parallels with marginal HNV areas across Europe. 相似文献

The ethnically homogeneous middleman groups (EHMGs), which are informal trading networks, are ubiquitous in less-developed economies where the legal infrastructure for contract enforcement is not well developed. This paper develops a formal model of social interaction among members of the EHMG as well as in more general situations in a multi-ethnic or multi-cultural society consisting of identifiable ethnic or linguistic groups. Behavioral patterns are transmitted between generations and altered via imitation in social contacts. The model demonstrates how different discriminatory behavioral patterns can evolve and persist over time. One result is that the trust between such groups can increase due to a higher frequency of inter-group contacts. In concluding the paper, we speculate about how the model can be expanded to include changes in legal structures, especially contract law. This could lead to an increase in the trust between the different groups. 相似文献

Japan's Great Kantō Earthquake of 1 September 1923 devastated the area around Tokyo and the country's main port of Yokohama. This article uses the earthquake as a case study to inform our understanding of the economics of disasters and the history of market integration. It seeks to test two main assumptions: first, that shifting demand and supply curves consequent on a disaster will have some impact on prices; and second, that any local changes in the disaster region are likely to be diffused across a wider geographical area. We make use of a unique monthly wholesale price dataset for a number of cities across Japan, and our analysis suggests three main findings: that price changes in the affected areas immediately following the disaster were in most cases reflected in price changes in Japan's provincial cities; that cities further away from the devastation witnessed smaller price changes than those nearer to the affected area; and that the observed pattern of price changes reflects the regional heterogeneity identified by scholars who have worked on market integration in Japan. 相似文献
