Social scientists and rural development interventionists inTanzania and in Sub-Saharan Africa depend mainly on conventionalsample surveys; in part this is a legacy of their basic training.Participatory rural appraisal and intervention approaches offera varied range of methods. We ask ourselves whether the resultsfrom participatory, rapid appraisals are conflicting and differentto those from sample surveys? This paper compares results ofa Rapid Participatory Rural Appraisal (PRA) with a conventionalsample survey. These surveys were conducted at the end of 1995and mid-1996 respectively, to establish socio-economic well-beingranks in Njombe district. A comparison of results shows thatthe well-being ranks established using PRA are valid and theapproach is reliable. The three qualitatively established well-beingranks differed empirically in many socio-economic indicators.These include resource endowment, labour force size, agriculturalland, livestock ownership, forest woodlot management, perceptionof food insecurity, technological advances in agricultural productionand natural resource management systems. Results show that thelow well-being group and female-headed households are disadvantaged.The goal of the Hifadhi Ya Mazingira-Njombe project is to developenvironmentally sustainable crop and livestock husbandry practicesin the district. The well-being ranking exercise has strongimplications for the project's strategy. We discuss the adoptedmethodology and implications. The paper recommends that developmentprogrammes and workers in Tanzania and Sub-Saharan Africa oughtto extend their approaches. It is time to include more of theparticipatory, relatively rapid rural appraisal and interventiontechniques. Benefits that they may accrue are time saving, lowercosts, quality information and stakeholder involvement.  相似文献

Global supply chains face a multitude of risks. A review of the recent literature reveals a few structured and systematic approaches for assessing risks in supply chains. However, there is no conceptual framework that ties together this literature. The purpose of this paper is to integrate literature from several disciplines ‐ including logistics, supply chain management, operations management, strategy, and international business ‐ to develop a model of global supply chain risk management. The implications for stakeholders and how future research could bring more insights to the phenomenon of global supply chain risk management are also discussed.  相似文献

Papua New Guinea (PNG) has much to learn from the Indonesian economic experience of coping with one booming sector while creating an environment in which the economy could generate jobs. PNG's macroeconomic policy adjustments to the boom-bust cycles which characterise its economy work extremely well by comparison to most other developing countries experiencing the same difficulties. At the microeconomic level, policy improvement has been harder, with the rhetoric far out-distancing the actual advances. The challenge is to improve the productivity of the agricultural sector, to raise the education levels, and to attract investment to provide employment. At present the investment environment is bleak because of the deteriorating law and order situation.  相似文献

Prior to the Asian financial crisis, most Asian exchange rates were de facto pegged to the US Dollar. During the crisis, many economies experienced a brief period of extreme flexibility. A ‘fear of floating’ gave reduced flexibility when the crisis subsided, but flexibility after the crisis was greater than that seen prior to the crisis. Contrary to the idea of a durable Bretton Woods II arrangement, Asia then went on to slowly raise flexibility and reduce the role for the US dollar. When the period from April 2008 to December 2009 is compared against periods of high inflexibility, from January 1991 to November 1991 and October 1995 to March 1997, the increase in flexibility is economically and statistically significant. This paper proposes a new measure of dollar pegging, the “Bretton Woods II Score”. We find that Asia has been slowly moving away from a Bretton Woods II arrangement.  相似文献

The learning process between supply chain entities is explored from the perspective of senior third‐party executives. Through grounded theory, a theoretical framework emerged that extends our understanding of learning within a supply chain by identifying the major constructs and learning stages comprising the basic social process of inter‐organizational learning. This framework provides significant insights into the complex process employed in a supply chain to share, disseminate, and store information; co‐create knowledge; and to derive a competitive advantage.  相似文献

A recent Deloitte study of 600 Supply Chain and C‐Level executives revealed that 45% felt that their supply chain risk management programs were only somewhat effective or not effective at all, while a mere 33% used risk management approaches to proactively and strategically manage supply chain risk based on conditions in their operating environment. Using a two‐method approach, the research summarized in this paper investigates the effectiveness of different supply chain risk management approaches by examining how performance varies when these approaches are applied under different risk conditions. The results counter prevailing knowledge regarding the appropriate use of such widely acknowledged risk management approaches as postponement and speculation, and highlight the dangers of functionally isolated decision making. The results lend credence to increasing calls for interdisciplinary research to address broad‐based supply and demand chain problems, and support the need to utilize performance metrics such as net profit to accurately assess supply chain decisions.  相似文献

This paper examines how unhedged currency exposure of firms varies with changes in currency flexibility. A sequence of four time periods with alternating high and low currency volatility in India provides a natural experiment in which changes in currency exposure of a panel of firms is measured, and the moral hazard versus incomplete markets hypotheses tested. We find that firms carried higher currency exposure in periods when the currency was less flexible. Our results support the moral hazard hypothesis: that low currency flexibility encourages firms to hold unhedged exposure in response to implicit government guarantees.  相似文献

A positive relationship betweencompetitive pressure and technical efficiency has been demonstratedby several studies; other studies hold forth that airline marketsbehave strategically. We bring these two literatures togetherby presenting a time series methodology to examine strategicpricing behavior and discussing the implications for airlineefficiency. We find evidence of dynamic, route-level, parallel( i.e. strategic) pricing despite highly variable price structures.A stable price relationship is consistent with successful coordinationof dynamic oligopolists and may highlight those routes wheresignificant market power exists. In light of previous research,this indicates that the airlines on these routes may not be attainingmaximum technical efficiency. For policy makers, this methodologyis useful for analyzing other markets which behave strategically.  相似文献

Despite improvements in production incentives, agricultural output in Africa remained sluggish through the 1990s. Low use of purchased inputs may be part of the cause of persistently low productivity in African agriculture. This article analyzes the roles of relative prices and transactions costs in explaining low use of chemical inputs among Tanzanian coffee growers. A sample selection model indicates that output prices exert great influence on input purchases and that both fixed and variable transactions costs affect input use decisions. Travel costs in input and output markets have distinct effects on input usage, implying distinct avenues for interventions to promote more intensive use of agricultural inputs.  相似文献
