This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids. 相似文献

This article draws a link between the risk management failures in the financial services industry and the educational philosophy and teaching constraints at business schools. An innovative application of prediction market technology within business education is proposed as a method that can be used to encourage students to think about risk in an open and flexible way. This article explains how prediction markets also provide students with the necessary experience to critically evaluate and stress‐test quantitative risk modeling techniques later in their academic and professional careers. 相似文献

American workers and employers a century ago formed microinsurance funds to provide sick pay to temporarily disabled workers. This article analyzes a 1908 survey of several hundred such microinsurers. Theoretically, a single cross‐section may yield evidence of asymmetric information, but cannot enable the separation of moral hazard and adverse selection effects. However, microinsurance fund managers and outside observers believed they did see separate such effects and so microinsurers created separate countermeasures to mitigate these problems. This article finds prima facie evidence of asymmetric information and suggestive evidence of the separability of informational asymmetries and the effectiveness of such countermeasures. 相似文献

We use firm‐level data to study corporate performance during the Great Depression era for all industrial firms on the NYSE. Our goal is to identify the factors that contribute to business insolvency and valuation changes during the period 1928‐1938. We find that firms with more debt and lower bond ratings in 1928 became financially distressed more frequently during the Depression, consistent with the trade‐off theory of leverage and the information production role of credit rating agencies. We also document for the first time that firms responded to tax incentives to use debt during the Depression era but that the extra debt used in response to this tax‐driven “debt bias” did not contribute significantly to the occurrence of distress. Finally, we conduct an out‐of‐sample test during the recent 2008‐2009 Recession and find that higher leverage and lower bond ratings also increased the occurrence of financial distress during this period. 相似文献

We introduce a new approach in measuring relative volatility between two markets based on the directional change (DC) method. DC is a data-driven approach for sampling financial market data such that the data are recorded when the price changes have reached a significant amplitude rather than recording data under a predetermined timescale. Under the DC framework, we propose a new concept of DC micro-market relative volatility to evaluate relative volatility between two markets. Unlike the time-series method, micro-market relative volatility redefines the timescale based on the frequency of the observed DC data between the two markets. We show that it is useful for measuring the relative volatility in micro-market activities (high-frequency data). 相似文献

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

This paper reports the results of a scientific survey of the equity valuation practices of CFA Institute members with equity analysis job responsibilities. Using an instrument designed to minimize biases in prior valuation surveys and sampling a larger group than in previous studies (13,500 investment professionals, resulting in 1,980 valid completed questionnaires), this paper documents professional practices in the selection of equity valuation approaches, including specific model variations and key input preferences. Important differences in practice were observed across geographies and employer firm types. 相似文献

This article examines the history of the office of Bankruptcy Registrar of the High Court of England and Wales. It is argued that the power of the registrars to act judicially grew from their authorisation to act pursuant to delegated powers introduced in 1869 and that this began a major shift in their role from being largely administrative to their current status as fully fledged (and renamed) insolvency and companies court judges. The fluidity of bankruptcy offices in the nineteenth century is also examined, demonstrating that certain bankruptcy officer‐holders moved freely between functions in the course of the development in the office of registrar from what might be called its administrative phase to the judicial phase with the eventual creation of a Bankruptcy Court and more recently the creation of a specialist insolvency and companies list in the new Business and Property Courts. Finally, it is argued that a factor in the foregoing developments and the increasing reputation of the bankruptcy registrars was the extension of their jurisdiction from pure bankruptcy work to include company insolvency, directors' disqualification cases and non‐insolvency company work, a significant increase in their trial work and their acquisition of an appellate jurisdiction. 相似文献

Slow growth over the last decade has prompted policy attention towards increasing R&D spending, often via the tax system. We examine the impact of R&D on firm performance, both by the firm's own investments and through positive (and negative) spillovers from other firms. We analyse panel data on US firms over the last three decades, and allow for time‐varying spillovers in both technology space (knowledge spillover) and product market space (product market rivalry). We show that the magnitude of R&D spillovers remains as large in the second decade of the 21st century as it was in the mid 1980s. Since the ratio of the social return to the private return to R&D is about four to one, this implies that there remains a strong case for public support of R&D. Positive spillovers appeared to temporarily increase in the 1995–2004 digital technology boom. We also show how these micro estimates relate to estimates from the endogenous growth literature and give some suggestions for future work. 相似文献

Despite the great importance attributed to intellectual capital (IC) in the past two decades or so, its measurement and management have remained elusive, mainly because of inappropriate prior models of IC measurement. The purpose of this study is, therefore, to make adjustments to an existing model, the Value Added Intellectual Coefficient (VAIC), and to present an adjusted‐VAIC model to measure IC. We tested our new model on data from 10 emerging and developed world markets and obtained more consistent results than prior studies. Our results indicate a significant positive relationship between IC and its components (human, innovation and physical capitals) and firm performance. Therefore, the adjusted‐VAIC model can be used with confidence to measure IC. Our study has important implications for both academia and industry concerning the measurement of IC. 相似文献
