This study examines governance and institutional factors that influence how public resources are allocated for nutrition interventions in the context of a developing country—Mozambique—with very high rates of malnutrition. Based on qualitative empirical analysis building on a political economy framework, we explore the importance of two agent-centred and two investment-centred factors that determine how decisions on budget allocation to nutrition are made. The analysis finds that public decisionmakers strongly favour highly visible nutrition investments and those with a short duration between the time that spending is incurred and outcomes or outputs are achieved. Co-ordination has been quite successful among donors, and mainly of a spatial nature. Co-ordination is significantly weaker among government agencies, given the absence of fiscal tools of the co-ordinating agency, and its placement in a sector ministry rather than at a supra-sectoral level. Champions as change agents have had a truly influential role in attracting more funding to nutrition and improving its allocation. But their influence is also fleeting and difficult to sustain. 相似文献

We recently introduced a research program on how firms can effectively capture fleeting opportunities using heuristics. Heuristics, we advocate, are the essence of strategy, especially in unpredictable markets where opportunities are often numerous, fast moving, and uncertain. Our emphasis on heuristics invites comparison with prominent research programs in cognitive psychology. We address this opportunity by comparing our “simple rules” heuristics approach with “heuristics‐and‐biases” and “fast‐and‐frugal” heuristics research. Collectively, the three approaches offer a rich understanding of heuristics. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

An effective strategy formation capability is a complex organizational resource—a dynamic capability that should lead to superior performance. Strategy scholars have examined the strategy formation capability from many perspectives. However, no study has examined a comprehensive model of strategy formation in the context of the firm's strategic orientation. We develop and examine such a model. The results show that strategic orientation moderates the relationship between different elements of the strategy formation capability and performance. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

The North American Free Trade Agreement (NAFTA) was designed to reduce tariff rates between Mexico, Canada and the U.S.A. over a period of ten years. However, lower tariff rates are only available to firms that comply with complicated and costly NAFTA filing regulations. Such regulations raise costs of small firms relative to large firms in a domestic industry which engages in trade between NAFTA countries. This implication of NAFTA regulations can lead to increased concentration in domestic industries, an hypothesis which can be tested as the transition period comes to an end. Finally, our model suggests an explanation for why the levels of trade from the U.S.A. to Mexico have been lower than general expectations. 相似文献

This special issue was aimed at advancing the literature examining the role of capabilities in innovation-based competitive strategy. Whilst the innovation literature has over the years moved away from its ‘product innovation’ pre-occupation to capture the role of other forms of innovation in value creation, the capability view has progressed from its ‘rigid’ or ‘static’ view to a ‘dynamic’ view in an effort to capture market dynamism. Despite the recent theoretical advancements the dynamic capability view still lacks a strong empirical base. Contributors to the capability literature over the recent years have adopted multiple research methods to capture capabilities that include cross-sectional designs, case studies and longitudinal studies. Within this backdrop, the articles that were selected for this special issue covers both conceptual and empirical approaches to examine the relationship between capabilities and technical and non-technical innovations and performance outcomes. This essay provides a future research agenda to advance this promising research field. It highlights the need for clearer conceptualizations and development of measures of dynamic capabilities, environmental conditions that underpin the development of dynamic capabilities within the firm and research into the much debated relationship between dynamic capabilities and competitive advantage and organizational performance. 相似文献

本文采用SML指数法测算了1998~2011年期间全国各地区的生产率指数和环境技术效率,进而在空间经济学框架下提出了经济关联、知识关联、规模收益和交通运输条件等可能引起效率集聚的因素,并运用“系统广义矩估计法”对这些因素的作用方向与方式作了实证检验。主要结论有:我国经济增长效率的空间分布具有明显集聚性;有限的技术效率是我国省域经济增长效率提升中的“短板”;中、西部地区具有以规模扩张为主要方向的粗放增长方式;经济关联、交通运输条件及产业结构等因素成为提升技术效率的“切入点”;FDI和资本密集型禀赋结构在经济增长效率提升中的作用具有“两面性”;我国省域经济增长效率表现出一定的趋同和溢出现象。 相似文献

随着世界经济的发展和我国社会主义市场经济的发展,科学技术和创新理论不断发展,终身教育、终身学习已成为社会发展的客观要求,许多国家都以立法的形式将终身学习纳入法治的轨道,中国改革开放30年来,社会经济也得到突飞猛进的发展,但是尚未建立有效的适合于会计人员终身学习的人文环境。文章从以人为本、良好的秩序、终身学习的科学理念、社会和谐、爱岗敬业精神、社会公平与平等方面研究会计人员终身学习人文环境建设,认为只有创建良好的人文环境,才能留住人才、用好人才,满足社会和经济发展的需要。 相似文献
