While financial statement analysis is a rich tool, there is no widely used holistic measure of the amount of change in corporate financial statements. Statistical decomposition analysis has been employed as an index of the amount of change, but has fallen into disuse because it does not allow negative accounting numbers. As a remedy, this paper suggests three distance measures adapted from cluster analysis that avoid this critical data limitation. We successfully apply these proposed distance measures to explain the total and systematic risk of stock returns (in the CAPM and Fama–French model), corporate bond ratings, and corporate distress.  相似文献

Social capital theory generally analyses network structures by focusing on the connections between players. However, it has been suggested by several authors that the absence of relations in a network or ‘structural holes’ is meaningful. The aim of our paper is to provide a global survey and appraisal of the academic research on structural holes and discuss its main measurements. We adopt a bibliometric approach and identify a typology of practices, developments, and issues related to structural holes. We highlight a strand of work on operationalization of structural holes, and discuss the various measures they propose. We provide numerical examples emphasizing the respective advantages and limitations of the studied measures. Based on our results, we propose a guide to using existing measures of structural holes according to the type (simple or complex) of network.  相似文献

Throughout the euro area crisis, financial fragmentation across jurisdictions became a prime concern for the single monetary policy. The ECB broadened the scope of its instruments and enacted a series of non-standard measures to engineer an appropriate degree of policy accommodation. The transmission of these measures through the currency union remained highly dependent on the financial structure and conditions prevailing in various regions. This paper explores the country-specific macroeconomic transmission of selected non-standard measures from the ECB using a global DSGE model with a rich financial sector: we extend the six-region multi-country model of Darracq Pariès et al. (2016), introducing credit and exchange rate channels for central bank asset purchases. The portfolio rebalancing frictions are calibrated to match the sovereign yield and exchange rate responses after ECB's Asset Purchase Programme (APP) first announcement. The domestic transmission of the APP through the credit intermediation chain is significant and quite heterogenous across the largest euro area countries. The introduction of global portfolio frictions on euro area government bond holdings by international investors opens up for a larger depreciation of the euro. The interaction between international and domestic channels affect the magnitude and the cross-country distribution of the APP impact.  相似文献

Regulatory heterogeneity continues to be identified as a challenge for food trade in the Association of Southeast Asian Nations (ASEAN) as the progress of harmonization of food standards among member states remains slow. Using a new and comprehensive database on nontariff measures (NTMs), this article examines the coverage, frequency, and diversity of NTMs for the food sector in Malaysia, and then estimates their impact on food imports from ASEAN. The food sector in Malaysia is found to be highly regulated, dominated by technical measures, namely, labeling for sanitary and phytosanitary and technical barriers to trade reasons, product quality, and restricted substances. The empirical results subsequently verify that, overall, technical measures are import restrictive. This article therefore contends that harmonization of food standards and regulations at the regional level is important for enhancing trade. However, building common ground for food safety regulations should be NTM‐ and sector‐specific, to realize progress in terms of regulatory convergence. This is particularly true for the food sector, since complete harmonization is not practical and not politically feasible.  相似文献

In a capital adequacy framework, risk measures are used to determine the minimal amount of capital that a financial institution has to raise and invest in a portfolio of prespecified eligible assets in order to pass a given capital adequacy test. From a capital efficiency perspective, it is important to be able to do so at the lowest possible cost and to identify the corresponding portfolios, or, equivalently, their payoffs. We study the existence and uniqueness of such optimal payoffs as well as their behavior under a perturbation or an approximation of the underlying capital position. This behavior is naturally linked to the continuity properties of the set‐valued map that associates to each capital position the corresponding set of optimal eligible payoffs. Upper continuity can be ensured under fairly natural assumptions. Lower continuity is typically less easy to establish. While it is always satisfied in a polyhedral setting, it generally fails otherwise, even when the reference risk measure is convex. However, lower continuity can often be established for eligible payoffs that are close to being optimal. Besides capital adequacy, our results have a variety of natural applications to pricing, hedging, and capital allocation problems.  相似文献

粮堆埋人事故发生率高,人员生还率低.为研究事故发生原因和预防措施,采用事故致因"2-4"模型对46起粮堆埋人事故进行分析.首先,从个人层面分析事故的直接原因和间接原因;其次,从组织层面分析事故发生的根本原因和根源原因;最后,构建粮堆埋人事故致因链,提出预防对策.结果表明:在不稳定粮堆表面作业、安全培训不到位等不安全动作和挡粮板设计不合理等不安全物态是导致事故的直接原因;安全知识不足、安全意识不高和安全习惯不佳是事故发生的间接原因;安全检查制度、外包管理制度、安全设施设备管理制度等的缺欠和落实不到位,结拱、挂壁处理和粮食出入仓作业规程等的缺欠或未严格规范人员作业是事故发生的根本原因;事故发生的根源原因是安全文化缺欠.  相似文献

The hypotheses that a firm's environmental performance has a positive impact on its financial performance and vice versa are statistically supported by Japanese data. However, this tendency for two‐way positive interaction appears to be only a relatively recent phenomenon. The tendency for realizing the two‐way interaction is not limited to the top‐scoring firms in terms of both financial and environmental performance. On the contrary, this is also a trend that can be observed fairly generally. Obviously, when we consider only scores of those companies that published the relevant information in their environmental reports, and conduct the statistical causality test with such information as additional input to the pooled time‐series and cross‐section data of financial performance, the results become more strongly significant. From the recent experience of environmental policies in Japan, we infer that information‐based environmental policy measures are effective to encourage the ongoing transition toward a more sustainable market economy.
