Financial research has given rise to numerous studies in which, on the basis of the information provided by financial statements, companies are classified into different groups. An example is that of the classification of companies into those that are solvent and those that are insolvent. Linear discriminant analysis (LDA) and logistic regression have been the most commonly used statistical models in this type of work. One feedforward neural network, known as the multilayer perceptron (MLP), performs the same task as LDA and logistic regression which, a priori, makes it appropriate for the treatment of financial information. In this paper, a practical case based on data from Spanish companies, shows, in an empirical form, the strengths and weaknesses of feedforward neural networks. The desirability of carrying out an exploratory data analysis of the financial ratios in order to study their statistical properties, with the aim of achieving an appropriate model selection, is made clear. 相似文献

The role of ‘opaque’ networks are analysed within the context of an infant economy with low levels of corporate governance. A period of economic expansion is studied, documenting the effects of credit liberalisation. This article outlines the significance of networks, emerging business cliques, particularly around financial institutions and the interlocking directorates these affiliations allow. Their effects upon financial reporting, business credibility and its effects upon the network life cycle are considered. Market manipulation, the importance of monitoring in instances of unsophisticated governance structures and the agents used (but particularly local/national press) are all analysed. 相似文献

The research purpose of this paper is to describe and analyse how three basic types of logistics firms differ in terms of their core capabilities and network development as well as the effects of the difference. Based on the resource-based view and the industrial network approach, a conceptual framework is developed to differentiate logistics firms. Two case studies of logistics firms are used as examples to demonstrate how the framework can be used. Logistics firms have clear differences in capabilities and network focus. These firms follow different dominating logics of value creation that make them develop in different ways and think totally differently. This research enhances our understanding of the different logics of logistics firms and their interdependence. They are complementary and interacting in the logistics service supply chain. Moving between the basic types of logistics firms means changing the capabilities and network focus, which is costly and difficult. The conceptual framework can be used as a tool to comprehend multiple types of logistics firms. It also helps us to analyze related strategic moves. 相似文献

The title of this paper reflects both the process and the outcome of the current undertaking. Frustrated with the current
state of the Middle East but encouraged by earlier attempts at modeling complex problems, the authors participated in a panel
discussion assembled to address the conflict and propose a possible road-map to peace. However, the participants of this project
did not come to a single course of action that will result in peace in the Middle East but did reach a consensus agreement
about a resolution that needs to be managed. This paper explores the process, the outcome and the factors that influence the
decision as well as potential pitfalls. The Analytic Network Process (ANP), a well known multicriteria decision making approach,
applied frequently in recent years to examine conflicts around the world, is used in this analysis. It provides a framework
for synthesizing judgments on the diverse aspects of the problem represented in the structure of the decision. It pieces together
these judgments in a holistic and logical way. 相似文献

以2007年被ST的30家上市公司和配对产生的30家正常经营上市公司为样本,以它们2002-2004年的财务指标为样本数据,运用基于数据挖掘的BP神经网络方法构建了上市公司财务困境预警模型。经实证表明,该模型具有良好的预测效果,研究结论对上市公司、投资者和债权人采取有效措施防范风险具有重要借鉴意义。 相似文献
