Industry classifications are used by investors, economists, and policy makers for a great variety of purposes. The traditional economic‐activity‐based systems (Global Industry Classification Standard, North American Industry Classification System, Standard Industrial Classification, and Fama–French) have been supplemented in recent years by alternative classification systems. Our purpose is to provide another alternative system that forms classification groups based on the structure of firm financial statements. Using cluster analysis, a multivariate tool that forms groups where their characteristics are similar within groups and distinct across groups, we form clusters of large U.S. firms based on their common‐size financial statements (percentage breakdowns of balance sheets and income statements). We characterize the financial clusters based on their industry classifications and other economic information and assess the ability of financial clusters and industry groups, separately and jointly, to explain stock return correlations of all pairs of firms. Our results demonstrate that using financial clusters and industry groups together proves advantageous relative to using either alone. 相似文献

Researchers in supply chain management have found over the past two decades that supply management should be not merely a purchasing function but a strategic tool for supply chain integration. Supply management, the cornerstone of the integration of industrial supply chains, has evolved as a key research area. Based on quantitative and qualitative investigations of 225 electronics manufacturing firms, we examine the organizational impacts of strategic supply management (SSM) and the contexts of company size, process type, ISO 9000 certification, and quality management (QM) implementation that facilitate such an endeavor. We reveal that SSM is essentially a quality management initiative that requires bilateral efforts for continuous improvement and thus is not associated with the basic requirements of ISO 9000. We find that SSM improves on-time shipments, reduces operational costs, and leads to customer satisfaction and improved business performance. Developed based on contemporary premises in supply chain and QM, this research refines our understanding of the relationships among quality initiatives, SSM, and organizational performance. 相似文献

This paper examines the relationships between split ratings and ratings migration. We find that bonds with split ratings are more likely to have future rating changes. A one-notch (more-than-one-notch) split rating increases the probability of rating change within one year of initial issuance by about 3% (6%). Furthermore, we find that about 30% of split rated bonds have their two ratings converge after four years of initial issuance. The rating convergence tapers off after three years, and the rating agency with a higher (lower) initial rating generally maintains a higher (lower) rating in subsequent years if the two ratings do not converge. We also show that rating transition estimation can be improved by taking into consideration split ratings. We find that one-year rating transition matrices are significantly different between non-letter-split rated bonds and letter-split rated bonds, and we show that the difference has an economically significant impact on the pricing of credit spread options and VaR-based risk management models. Overall, our results suggest that split ratings contain important information about subsequent rating changes. 相似文献

This paper argues that the microfoundations programme can be understood as an implementation of an underlying methodological principle—methodological individualism—and that it therefore shares a fundamental ambiguity with that principle, viz, whether the macro must be derived from and therefore reducible to, or rather consistent with, micro-level behaviours. The pluralist conclusion of the paper is not that research guided by the principle of microfoundations is necessarily wrong, but that the exclusion of approaches not guided by that principle is indeed necessarily wrong. The argument is made via an examination of the advantages claimed for dynamic stochastic general equilibrium models, the relationship between parts and wholes in social science, and the concepts of reduction, substrate neutrality, the intentional stance and hypostatisation. 相似文献

The HR world is abuzz with talk of big data and the transformative potential of HR analytics. This article takes issue with optimistic accounts, which hail HR analytics as a ‘must have’ capability that will ensure HR's future as a strategic management function while transforming organisational performance for the better. It argues that unless the HR profession wises up to both the potential and drawbacks of this emerging field and engages operationally and strategically to develop better methods and approaches, it is unlikely that existing practices of HR analytics will deliver transformational change. Indeed, it is possible that current trends will seal the exclusion of HR from strategic, board‐level influence while doing little to benefit organisations and actively damaging the interests of employees. 相似文献

Simulation-based costing (SBC) has been slow to be adopted by the traditional cost estimating community. This can be attributed to many factors, including complexity, how to gather data and develop probabilistic inputs, cost of SBC software, and a lack of understanding of the benefits of developing cost versus risk profiles. This article presents an overview of how SBC can be effectively utilized for early phase life cycle cost (LCC) estimation. A formal process for conducting LCC incorporating SBC is presented not only to provide a structured approach but to also convey to stakeholders how such a study is conducted. This article also presents a case study where total ownership cost versus risk profiles were developed using this proposed process in order to support budgetary and planning considerations for a large environmental remediation project. This research argues that SBC is needed during the concept exploration phase because this is when budgets are often fixed and expectations set. 相似文献

According to most classifications, Sub‐Saharan Africa is the region of the world with the highest presence of fragile states. In this paper we examine the relationship between fragility and poverty, suggesting that countries may become trapped in a vicious circle of fragility and low levels of wellbeing. We consider fragility as a continuum and begin by reviewing available measures. These show the high presence of fragility in Sub‐Saharan Africa and allow the more fragile countries to be identified. There is seen to be a strong association between fragility, poor growth performance, and lower wellbeing in Sub‐Saharan Africa. Building on the strong evidence for the two‐way relationship between economic growth and poverty, we present an analysis of how the vicious circle linking poorer welfare outcomes and fragility may be able to be broken. We argue that building successful institutions is key here, and this can be enabled by specific policy interventions that are both poverty reducing and productive. 相似文献

This paper attempts to investigate empirically the investment-growth relationship in China. Using the exogeneity framework pioneered by Engle et al. (1983) and Engle and Hendry (1993), we find that fixed investment is a key determinant of China's economic growth, which, surprisingly, has not been rigorously examined in the literature. The super exogeneity test results suggest that there exists a robust (or structurally invariant) relationship between capital formation and income growth, thereby giving credence to policy evaluation. 相似文献
