The Effects of Internal Board Networks: Evidence from Closed-End Funds 内部董事会网络的影响:来自封闭式基金的证据
Pub Date : 2018-05-31 DOI: 10.2139/ssrn.3163884

Recent literature emphasizes the importance of a director's external network of social connections. I use a sample of closed-end funds to show that internal, within-board connections are also significant determinants of shareholder value. I find that boards with shared education, employment, and family backgrounds exhibit lower market values, higher expense ratios, higher director compensation levels, and an increased likelihood of financial misrepresentation. Director turnover is lower within these boards, and new director appointments are more likely to share connections with incumbent directors. I conclude that internal board networks negatively impact a firm's governance environment and overall monitoring quality.
最近的文献强调了导演的外部社会关系网络的重要性。我以封闭式基金为样本,表明内部、董事会内部的联系也是股东价值的重要决定因素。我发现,拥有共同教育、就业和家庭背景的董事会表现出更低的市场价值、更高的费用比率、更高的董事薪酬水平,以及更大的财务虚假陈述的可能性。这些董事会的董事流动率较低,新董事任命更有可能与现任董事共享关系。我的结论是,内部董事会网络对公司的治理环境和整体监控质量产生负面影响。

Ownership Structure and Bank Risk: The Effects of Crisis, Market Discipline and Regulatory Pressure 股权结构与银行风险:危机、市场纪律和监管压力的影响
Pub Date : 2018-03-27 DOI: 10.2139/ssrn.3150353

Using a large panel of US BHC over the 2001:Q1-2015:Q4, we investigate the risk-taking behaviors of banks within a comparison perspective – between public and private banks - where there exists substantial differences of asymmetry information and agency problems. We document evidence of greater stability of public banks versus their private peers. However, public banks become riskier than private banks during the last crisis. These findings suggest a mixed evidence of risk-taking mitigating role of listing status. Regulatory pressure is effective in limiting risk taking by undercapitalized public banks before, but not during the crisis, casting doubt the effectiveness of regulators during the turmoil times. Public banks with high franchise value expose to risk less than others during the crisis. Debtholders discipline is ineffective in curbing the risk-taking behavior of banks. Our study is of interest for regulators, policymakers who are in search of improving bank risk-taking behavior.
利用2001年第一季度至2015年第四季度的大型美国BHC小组,我们从比较的角度研究了银行的风险承担行为-在公共银行和私人银行之间-其中存在着信息不对称和代理问题的实质性差异。我们记录了公共银行比私人银行更稳定的证据。然而,在上次危机中,公共银行比私人银行风险更大。这些发现表明,上市地位在降低风险方面的作用好坏参半。在此之前,监管压力在限制资本不足的公共银行的风险承担方面是有效的,但在危机期间则不然,这让人怀疑监管机构在动荡时期的有效性。在危机中,拥有高特许经营价值的公共银行比其他银行承担的风险要小。债权人纪律对于抑制银行的冒险行为是无效的。我们的研究对正在寻求改善银行冒险行为的监管机构和政策制定者很有意义。

The change subsequent to the sub-prime crisis pushed pressure on decreased financial products complexity, going from exotics to vanilla options but increase in pricing efficiency. We introduce in this paper a more efficient methodology for vanilla option pricing using a scenario based particle filter in a hostile data environment. In doing so we capitalise on the risk factor decomposition of the the Implied Volatility surface Parameterization (IVP) recently introduced in order to define our likelihood function and therefore our sampling methodology taking into consideration arbitrage constraints.
次贷危机之后的变化对金融产品复杂性的降低施加了压力,从新奇的期权变成了普通的期权,但定价效率提高了。在本文中,我们介绍了一种更有效的香草期权定价方法,该方法使用基于场景的粒子过滤器在敌对数据环境中进行定价。在这样做时,我们利用最近引入的隐含波动率表面参数化(IVP)的风险因子分解,以定义我们的似然函数,因此我们的抽样方法考虑到套利约束。

Claim is the largest expenses of an insurance company. Therefore, claims management is seen as an essential tool of image boosting in insurance industry. Excellence in claims handling gives an insurance company a competitive edge over its competitors. For an insurance company, claims processing is one of its core activities. It could be said to be the main reason why insurance companies are established. Managing it more effectively and efficiently, aligning it with corporate business objectives, and achieving real-time operational awareness are high priorities of an insurance company. This is because claims processing touches all part of the organization, affecting competitive positioning, customer service, fraud management, risk exposure, cost control and Information Technology infrastructure. The objective of this research therefore, is to empirically investigate the impact of claims management on the profitability of non-life insurance companies in the Nigeria insurance industry. Hypotheses were tested to find out whether claims management is significantly related to profitability of non-life insurance companies in Nigeria. The study adopts longitudinal design which follow the same sample over time and make repeated observations; hypotheses were tested using correlation analysis. The study revealed that there is a significant relationship between claims management and the operating cost of non-life insurance companies in Nigeria. However, the study revealed that there is no significant relationship between claims management and profitability of non-life insurance companies in Nigeria. It is recommended that the claims management department should be properly structured with highly technical, trained and experience staff so as to manage the claims of insurance companies properly as a well managed claim lead to profitability through repeated purchase.
理赔是保险公司最大的一项开支。因此,理赔管理被视为保险业形象提升的重要工具。卓越的理赔处理使保险公司比其竞争对手具有竞争优势。对于保险公司来说,理赔处理是其核心活动之一。这可以说是保险公司成立的主要原因。更有效和高效地管理它,使其与公司业务目标保持一致,并实现实时操作意识是保险公司的首要任务。这是因为索赔处理涉及组织的所有部分,影响竞争定位、客户服务、欺诈管理、风险暴露、成本控制和信息技术基础设施。因此,本研究的目的是实证调查索赔管理对尼日利亚保险业非寿险公司盈利能力的影响。假设进行了检验,以找出索赔管理是否与尼日利亚非寿险公司的盈利能力显著相关。本研究采用纵向设计,对同一样本进行长期跟踪,重复观察;采用相关分析对假设进行检验。研究表明,尼日利亚非寿险公司的索赔管理与运营成本之间存在显著关系。然而,研究表明,尼日利亚非寿险公司的索赔管理与盈利能力之间没有显著的关系。建议理赔管理部门结构合理,配备技术水平高、训练有素、经验丰富的员工,妥善管理保险公司的理赔,使理赔管理得当,通过反复购买实现盈利。

Governing the Good State Shareholder: The Case of the OECD Guidelines on Corporate Governance of State-Owned Enterprises 治理好国有股东:以经合组织国有企业公司治理指南为例
Pub Date : 2018-02-01 DOI: 10.54648/eulr2018005

The newly revised Guidelines on Corporate Governance of State-Owned Enterprises (2015) by the OECD are fast emerging as a new regulatory paradigm for the administration of State-owned enterprises and the organization of the State ownership function. This article analyses the Guidelines’ policy prescriptions, governance strategies, and integration into global governance. Noting that the instrument operates by governing the shareholder’s internal make-up, decision-making and objective setting, the article argues that the Guidelines amount to a robust model for an ideal State shareholder – the Good State Shareholder. Efficient, engaged, and accountable, the Good State Shareholder emerges as a critical actor in the contemporary global economy, where States continue to amass and command immense shareholder power. However, when juxtaposed with the recent attempts by the UN to adopt State ownership as an instrument of human rights governance, the fault lines of the Good State Shareholder model, as well as the emerging techniques of shareholder governance, are exposed.
经合组织新修订的《国有企业公司治理指南》(2015年)正迅速成为国有企业管理和国有职能组织的新监管范式。本文分析了《纲要》的政策处方、治理策略以及与全球治理的融合。文章指出,该工具通过对股东的内部构成、决策和目标设定进行管理而发挥作用。文章认为,《准则》相当于理想国家股东——良好国家股东的一个强有力的模式。高效、参与和负责任的良好国家股东成为当代全球经济中的关键角色,各国继续积累和掌握巨大的股东权力。然而,当与联合国最近将国家所有权作为人权治理工具的尝试并置时,良好国家股东模式的断层线以及新兴的股东治理技术就暴露出来了。

Will Tenure Voting Give Corporate Managers Lifetime Tenure? 任期投票会给公司经理带来终身任期吗?
Pub Date : 2018-02-01 DOI: 10.2139/ssrn.3107225
Paul H. Edelman, Wei Jiang, Randall S. Thomas
Dual-class voting systems have been widely employed in recent initial public offerings by large tech companies, but have been roundly condemned by institutional investors and the S&P 500. As an alternative, commentators have proposed adoption of tenure voting systems, where investor voting rights increase with the length of time that they hold shares. In furtherance of this proposal, some Silicon Valley investors have requested that the SEC permit the creation of a new stock exchange where all of the companies will be required to use tenure voting systems. Is tenure voting a better choice than dual-class stock for both corporate management and shareholders? In this paper, we review the arguments for and against tenure voting that have been made in the literature. In order to shed light on these claims veracity, we generate the first data base that documents institutional investor portfolio turnover rates for stock. We use this data to inform our mathematical voting model of tenure voting to show how its adoption would affect control rights within the corporation. We make two main findings that shed light on this question. First, we show that when corporate management holds a large block of company stock prior to the implementation of tenure voting, and retains at least 20-30% of the total number of company shares on a long term basis, then tenure voting will insure that corporate managers maintain control of the company even in the face of an attempted change of control transaction by a highly motivated dissident shareholder. Our second important finding is that if corporate management chooses to sell off its large initial block of the company’s stock over time, so that inside ownership levels drop eventually down to a low percentage level with the majority of ownership held by institutional shareholders with different investment horizons, then the use of tenure voting systems does little to protect management control in a proxy contest for corporate control. We conclude that tenure voting does indeed represent an intermediate form of voting control from a managers’ perspective: it does not guarantee management control, as dual-class share structures do, but does give control to management who maintain large equity stakes in the firm. Institutional investors are likely to see it as an improvement over dual-class stock structures in terms of giving them corporate governance rights, although less advantageous to these shareholders’ rights than a one share, one vote voting system.
近年来,大型科技公司在首次公开发行(ipo)中广泛采用了双层投票制度,但遭到了机构投资者和标准普尔500指数(S&P 500)的严厉谴责。作为替代方案,评论人士建议采用终身投票权制度,即投资者的投票权随着持股时间的延长而增加。为了推进这一提议,一些硅谷投资者要求美国证券交易委员会允许创建一个新的证券交易所,所有公司都将被要求使用任期投票制度。对公司管理层和股东来说,终身投票权是否比双重股权结构更好?在本文中,我们回顾了文献中提出的支持和反对任期投票的论点。为了阐明这些说法的真实性,我们生成了第一个记录机构投资者投资组合股票换手率的数据库。我们使用这些数据来告知我们的终身任期投票的数学投票模型,以显示其采用将如何影响公司内部的控制权。我们有两个主要发现来阐明这个问题。首先,我们表明,当公司管理层在实施任期投票之前持有大量公司股票,并长期保留至少20-30%的公司股份时,那么任期投票将确保公司经理即使面对高度动机的持不同政见的股东试图改变控制权交易时也能保持对公司的控制。我们的第二个重要发现是,如果公司管理层选择随着时间的推移出售其最初持有的大量公司股票,从而使内部所有权水平最终下降到一个较低的百分比水平,而大多数所有权由不同投资范围的机构股东持有,那么在公司控制权的代理权竞争中,使用任期投票制度对保护管理层控制权几乎没有作用。我们得出的结论是,从管理者的角度来看,任期投票确实代表了一种中间形式的投票控制:它不像双重股权结构那样保证管理层的控制,但确实赋予了持有公司大量股权的管理层控制权。机构投资者可能会认为,这是对双重股权结构的改进,因为它赋予了他们公司治理权,尽管对这些股东的权利来说,不如一股一票的投票制度有利。

The Fragility of Market Risk Insurance 市场风险保险的脆弱性
Pub Date : 2018-01-01 DOI: 10.2139/ssrn.2972295
R. Koijen, Motohiro Yogo
Insurers sell retail financial products called variable annuities that package mutual funds with minimum return guarantees over long horizons. Variable annuities accounted for $1.5 trillion or 34 percent of U.S. life insurer liabilities in 2015. Sales fell and fees increased after the 2008 financial crisis as the higher valuation of existing liabilities stressed risk-based capital. Insurers also made guarantees less generous or stopped offering guarantees entirely to reduce risk exposure. We develop an equilibrium model of insurance markets in which financial frictions and market power are important determinants of pricing, contract characteristics, and the degree of market incompleteness.
保险公司出售一种名为可变年金的零售金融产品,这种产品将共同基金打包,在长期内保证最低回报。2015年,可变年金占美国寿险公司负债的1.5万亿美元,占34%。2008年金融危机后,由于现有负债估值上升,对基于风险的资本构成压力,销售额下降,费用增加。保险公司也降低了担保力度,或完全停止提供担保,以降低风险敞口。我们建立了一个保险市场的均衡模型,其中金融摩擦和市场力量是定价、合同特征和市场不完备程度的重要决定因素。

Corporate Governance Mechanisms and Bank Performance: Evidence from the Greek Banks during Crisis Period 公司治理机制与银行绩效:来自危机时期希腊银行的证据
Pub Date : 2017-04-28 DOI: 10.21511/IMFI.14(1-1).2017.02

This paper is the first research attempt that investigates the impact of a large number of corporate governance mechanisms on the performance of Greek banks, employing widely accepted in the literature of corporate governance econometric models. Results indicate that system GMM models are more suitable methodological tools than pooled OLS and fixed effects models to address well-known econometric problems, such as endogeneity, simultaneity and unobserved heterogeneity of individual banks. The findings, as derived from the application of GMM models, imply that increasing the board size and the number of independent directors can both have a positive impact on the performance of Greek banks, but only up to a certain point. Thus, bank efficiency will increase as board size and the proportion of independent directors grow up to a point where these relationships hit a maximum from which bank performance decreases. Our multi-model estimations failed to trace any significant contribution of the number of female and foreign directors on the performance of Greek banks. Finally, the dual appointment of a CEO as Chairman appears to affect negatively two out of four proxies of bank performance. Overall, the results provide support for the positive impact of corporate governance mechanisms on the performance of Greek banks. The significance of these findings increases, considering that the period under study (2008-2014) is marked by high market volatility and uncertainty due to the well-known debt crisis that plagues Greece since the beginning of 2008.
本文首次尝试采用文献中广为接受的公司治理计量经济模型,研究大量公司治理机制对希腊银行绩效的影响。结果表明,系统GMM模型比集合OLS模型和固定效应模型更适合于解决众所周知的计量经济学问题,如单个银行的内生性、同时性和未观察到的异质性。运用GMM模型得出的研究结果表明,增加董事会规模和独立董事数量对希腊银行的绩效都有积极影响,但仅在一定程度上。因此,银行效率将随着董事会规模和独立董事比例的增长而增加,当这些关系达到最大值时,银行绩效就会下降。我们的多模型估计未能追踪到女性和外国董事数量对希腊银行业绩的任何重大贡献。最后,首席执行官兼董事长的双重任命似乎对银行业绩的四分之二的代理产生了负面影响。总体而言,研究结果支持公司治理机制对希腊银行绩效的积极影响。考虑到研究期间(2008-2014年)由于众所周知的债务危机自2008年初以来一直困扰着希腊,因此市场波动和不确定性很高,这些发现的重要性增加了。

The findings, as derived from the application of GMM models, imply that increasing the board size and the number of independent directors can both have a positive impact on the performance of Greek banks, but only up to a certain point. Thus, bank efficiency will increase as board size and the proportion of independent directors grow up to a point where these relationships hit a maximum from which bank performance decreases. Our multi-model estimations failed to trace any significant contribution of the number of female and foreign directors on the performance of Greek banks.

Despite predictions of their demise in the aftermath of the collapse of socialist economies in Eastern Europe, state-owned enterprises (SOEs) are very much alive in the global economy. The relevance of listed SOEs — firms still subject to government ownership, a portion of whose shares are traded on public stock markets — has persisted and even increased around the world, as policymakers have encouraged the partial floating of SOE shares either as a first step toward, or as an alternative to, privatization. In this article, we evaluate the governance challenges associated with mixed ownership of enterprise, and examine a variety of national approaches to the governance of listed SOEs, with a view to framing a robust policy discussion in the many countries where SOE reform is a topic of major significance. We describe the evolution and current status of the institutional framework applicable to listed SOEs in eight different jurisdictions, reflecting a variety of economic, legal, and political environments: France, the United States, Norway, Colombia, Brazil, Japan, Singapore, and China. We leverage the lessons from this comparative analysis to critique the policy prescriptions of international agencies such as the OECD, and to frame policy suggestions of our own.
尽管有预测称,随着东欧社会主义经济的崩溃,国有企业将会消亡,但它们在全球经济中依然生机勃勃。上市国有企业的重要性在全球范围内持续存在,甚至有所增加,因为政策制定者鼓励国有企业部分上市,作为私有化的第一步或替代方案。上市国有企业仍归政府所有,其中一部分股票在公开股票市场上交易。在本文中,我们评估了与企业混合所有制相关的治理挑战,并研究了上市国有企业治理的各种国家方法,以期在国有企业改革具有重大意义的许多国家建立强有力的政策讨论。我们描述了八个不同司法管辖区适用于上市国有企业的制度框架的演变和现状,反映了不同的经济、法律和政治环境:法国、美国、挪威、哥伦比亚、巴西、日本、新加坡和中国。我们利用这种比较分析的经验教训来批评经合组织等国际机构的政策处方,并提出我们自己的政策建议。
