Although integrated marketing communication (IMC) has progressed towards mid-range maturity level, its full-scale adoption has been impeded by a lack of consensus on its defining constructs. The purpose of this study is to move from abstraction to define the construct of strategic integration (SI) and develop this into a management tool, thus making an important contribution to both the theory and practice of IMC. Drawing from both IMC and strategic management literature, the construct of SI is operationalised into a number of key factors and a well-cited management model, Fuchs' ‘integration valuator’ is explored as the starting point of a measurement tool for IMC. To do this, a Delphi study invites the scrutiny of an expert panel of world-leading IMC researchers and practitioners. The panel validated the model construction process, redefined overarching constructs and key factors with a high degree of consensus, supported a process measure, suggested a weighted evaluation measure and recognised the importance of developing such a measure. They delivered clear and consistent imperatives guiding model development. The result is a measure of SI that evaluates organisational proficiency and diagnoses the integration of IMC campaigns. It also advances theory by providing a better understanding of the construct of SI.  相似文献

ABSTRACT

In this paper we examine the mean-reversion and long-memory properties in the stock market indexes of some Latin American countries by means of fractional integration. In doing so, we allow for a much richer degree of flexibility in the dynamic behaviour of the series not achieved when using the classical representations based on I(0) or I(1) processes. We use a semiparametric local Whittle estimator based on the frequency domain. The results show that the order of integration of the series is higher than 1 for Argentina, Venezuela and Colombia and is around 1 or slightly higher for Mexico. The results also show that the unit root cannot be rejected for the case of Brazil. Splitting the samples around the periods of crisis, we find long-memory stock market returns in the pre-crisis period for all countries except Brazil. However, using post-crisis data, the unit-root cannot be rejected, which might be consistent with the Efficient Market Hypothesis. A notable exception is the case of Colombia, where long memory is also found in the returns for the post-crisis period.

RESUMEN. En este estudio examinamos las propiedades de la reversión media y de la memoria prolongada en los índices del mercado bursátil en algunos países latino-americanos, a través de la integración fraccional. Utilizando este método, permitimos la ocurrencia de una flexibilidad mucho más rica en el comportamiento dinámico de las series, que no se puede lograr con el uso de las representaciones clásicas, basadas en los procesos I(0) o I(1). Utilizamos un estimador Whittle local semiparamétrico, fundamentado en el dominio de la frecuencia. Los resultados obtenidos muestran que el orden de integración de la serie es mayor a 1 para Argentina, Venezuela y Colombia, y alrededor de o poco más de 1 para México. Además, los resultados también demuestran que, en el caso brasileño, no puede rechazarse la unidad raíz. Al dividir las muestras alrededor de los períodos de crisis, descubrimos que el mercado bursátil con memoria prolongada vuelve a aparecer en el período pre crisis en todos los países menor Brasil. Sin embargo, si usamos los datos post crisis no podemos rechazar la unidad raíz ya que la misma puede ser coherente con la Hipótesis del Mercado Eficiente. Una excepción notable esel caso de Colombia, donde la memoria prolongada también se encuentra en los retornos para el período post crisis.

RESUMO. Neste artigo examinamos as propriedades de reverãs média e memória longa nos índices de mercados de aç[otilde]es de alguns países latino-americanos por meio da integração fracionária. Com isto, permitimos um grau de flexibilidade bem maior no comportamento dinâmico da série, não obtida quando se usam representaç[otilde]es clássicas baseadas nos processos I(0) e I(1). Empregamos um estimador Whittle local semiparamétrico baseado no domínio da freqüência. Os resultados mostram que a ordem de integração das série é maior que 1 para a Argentina, Venezuela e Colômbia e em torno de 1 ou ligeiramente maior para o México. Os resultados também mostram que a raiz unitária não pode ser rejeitada para o caso do Brasil. Dividindo-se as amostras em torno dos períodos de crise, encontramos retornos de mercado de aç[otilde]es de memória longa no período pré-crise para todos os países, exceto o Brasil. Entretanto, usando dados pós-crise, a raiz unitária não pode ser rejeitada, o que poderia ser compatível com a Hipótese do Mercado Eficiente. Uma exceção notável é o caso da Colômbia, onde a memória longa também se encontra nos retornos para o período pós-crise.  相似文献

面向信息集成的企业信息管理   总被引:1,自引:0,他引:1  
企业决策所面临的信息孤岛问题已成为现代信息管理的瓶颈,从而引出信息集成技术理念。但单从技术角度来进行信息集成,并不能解决问题。信息集成是一个系统化过程,除了要依靠技术外,还要有相应的组织结构和人力资源的配置管理,它实际上是一个深入的企业信息管理问题。  相似文献

欧洲联盟内部人员自由流动,同商品、服务和资本的自由流动一起,构成了欧洲经济一体化的基本内容.人员在成员国之间自由流动,直接冲击成员国现行的经济、社会等制度,因此往往遭遇障碍和歧视.欧盟从建立时起,就注重对人员自由流动的法律调整,并形成了自己鲜明的立法特点.我国正处于城市化的高潮时期,人员流动正迅速发展.我们应该借鉴欧盟的经验,加强人员流动方面的立法,以确保人员流动有序进行,促进改革开放的健康、和谐发展.  相似文献

This paper exploits the unique case of European market integration to investigate the relationship between integration and price convergence in international markets. Using a panel data set of car prices, we examine how the process of integration has affected cross-country price dispersion in Europe. We find surprisingly strong evidence of convergence towards both the absolute and the relative versions of the Law of One Price (LOOP). Our analysis illuminates the main sources of segmentation in international markets and suggests the type of institutional changes that can successfully reduce it.  相似文献

The centrality of cross‐functional integration (CFI) to supply chain theory and practice has long been recognized. Yet researchers continue to struggle with consistently defining or measuring the CFI construct, thus limiting the utility of CFI research. This research develops (1) a comprehensive definition of CFI that synthesizes previous supply chain research and (2) a valid set of scale items that measure the conceptual domain outlined by this definition. The goal is to build a common foundation for extending knowledge on CFI's antecedents and consequences, and ultimately to improve scholars’ ability to guide a broader practitioner community still struggling to achieve integration in their organizations.  相似文献

结合欧盟统计局以及欧洲央行2010和2011年公布的最新数据,分别从财政赤字、公共债务、失业率和通胀率等几个主要宏观经济指标出发,分析了欧洲主权债务危机的最新进展。研究表明,此次欧洲主权债务危机的爆发与欧洲一体化进程的缺陷密不可分。这种缺陷集中表现为欧盟发展至今的数次扩大,越来越凸显一体化扩张过快问题,以致现有成员经济发展水平差距较大,当遭遇不对称冲击时,难免使一体化陷入两难境地,也使得危机应对措施的效力大打折扣;同时,欧盟在推进货币一体化过程中,忽视了成员国之间的财政合作问题,财政一体化的缺失导致债务危机在所难免。  相似文献

关于物流概念本质的再思考   总被引:4,自引:0,他引:4  
本文认为,在目前对物流概念的理解和解释中,有一些背离了物流的本质。其主要原因,一是对物流定义的把握上存在偏差,关注的是“物资流动”活动的管理而非“物资流动”活动本身;二是在运输与物流的关系上认识模糊,简单地将二者等同起来;三是混淆了物流与计划经济时期物资流通的概念;四是对物流的发展变化缺乏足够的了解,不熟悉物流系统整合范围不断扩大的进程。文章提出,准确理解物流概念的本质和内涵,应站在货主企业的角度,牢牢把握系统整合这条主线,但研究物流、实践物流可以有不同的视角。  相似文献
