This paper examines the evolution of the attention paid by a sample of EU banks on IT governance. We propose an analysis based on IT public disclosure to contribute to the less explored strand of literature on IT governance transparency. We explore if the attention paid by banks to this topic has grown after the crises and if the greater importance ascribed to IT governance is due to the Supervisors’ pressure or the value-driven decisions. In particular, we test if, as for other corporate governance mechanisms, there is a verifiable linkage between IT governance (disclosure) and banks’ performance.
本文考察了欧盟银行对IT治理关注的演变。我们提出了一个基于IT公开披露的分析,以促进对IT治理透明度的较少探索的文献链。我们将探讨银行对这一主题的关注是否在危机后有所增加,以及IT治理的更大重要性是否归因于监管机构的压力或价值驱动的决策。特别是,对于其他公司治理机制,我们检验了IT治理(披露)与银行绩效之间是否存在可验证的联系。

Most of the studies in corporate governance in banks and other types of firms investigate board diversity and quality separately, without considering the possible relationship between these two. To fill this gap, this study investigates through a new methodological approach the level of quality and diversity of the boards of a sample of Italian banks using a proprietary hand-collected database; in addition, it examines the relationship between diversity and quality of boards to verify whether more diversity consistently relates to higher quality, in accordance with the regulatory approach. Evidence shows that especially small and mutual banks need to improve quality and diversity, as they probably suffer from their limited attractiveness to top profile directors. Moreover, on analyzing interrelations we find evidence of a positive association between board diversity and quality. In particular, financial skills and experience of directors improve the qualitative level of banking boards.
大多数关于银行和其他类型公司的公司治理的研究分别调查董事会多样性和质量,而没有考虑这两者之间可能存在的关系。为了填补这一空白,本研究使用专有的手工收集数据库,通过一种新的方法方法调查意大利银行样本董事会的质量和多样性水平;此外,它还检查了董事会多样性和质量之间的关系,以验证是否根据监管方法,更多的多样性始终与更高的质量相关。有证据表明,尤其是小型银行和互助银行需要提高质量和多样性,因为它们对知名董事的吸引力可能有限。此外,在分析相互关系时,我们发现董事会多样性与质量之间存在正相关的证据。特别是,董事的财务技能和经验提高了银行董事会的质量水平。

This study examines whether there is a strong relationship between stock liquidity, which proxies for the implicit cost of trading shares, and future stock returns in an asset-pricing context in the UK stock market. The time period, 1994–2016, includes the most recent global financial crisis that drained liquidity from financial markets worldwide. Four different measures of stock liquidity are employed; the empirical findings indicate that liquidity is a systematic pricing factor and explains a significant portion of the variation in stock returns, even after the inclusion of the other traditional risk factors. The results are robust to both forms of liquidity, either as a residual effect or in its original form as a separate risk factor. Finally, for the first time quantile regression is applied, showing that the liquidity risk factor (LIQ) absorbs a significant portion of the information content of the size and value factors, while remaining independent of the momentum factor.
本研究考察了股票流动性(代表交易股票的隐性成本)与英国股票市场资产定价背景下的未来股票回报之间是否存在强烈关系。这段时间为1994年至2016年,包括最近一次全球金融危机,导致全球金融市场的流动性枯竭。采用了四种不同的股票流动性衡量标准;实证结果表明,即使在纳入其他传统风险因素后,流动性也是一个系统性定价因素,并解释了股票收益变化的重要部分。结果对两种形式的流动性都是稳健的,无论是作为剩余效应还是作为单独风险因素的原始形式。最后,首次应用分位数回归,表明流动性风险因素(LIQ)吸收了规模和价值因素的很大一部分信息含量,而与动量因素保持独立。

THE RELATIONSHIP BETWEEN STOCK RETURN SKEWNESS AND BANK FEATURES 股票收益偏度与银行特征的关系
Q3 Economics, Econometrics and Finance Pub Date : 2018-12-01 DOI: 10.1142/S2282717X1850010X
S. Bressan, Alex Weissensteiner
This paper studies to what extent bank-specific characteristics relate to stock return skewness. The main finding is that stock return skewness decreases significantly in bank size, measured in terms of total assets, i.e stocks of large banks are less skewed than those of small banks. This result holds for backward-looking skewness computed using the past stock returns, as well as for forward-looking skewness extracted from stock options. We interpret the empirical evidence by arguing that bank size increases the likelihood to have severe losses, to the point that investors expect to be compensated by receiving higher expected returns.
本文研究了银行特征在多大程度上与股票收益偏度有关。主要发现是,以总资产衡量,股票回报偏度在银行规模中显著降低,即大银行的股票比小银行的股票偏度更小。这一结果适用于使用过去股票收益计算的向后偏度,以及从股票期权中提取的前瞻性偏度。我们对经验证据的解释是,银行的规模增加了遭受严重损失的可能性,以至于投资者期望通过获得更高的预期回报来获得补偿。

AN EQUILIBRIUM MODEL FOR AN OTC DERIVATIVE MARKET UNDER A COUNTERPARTY RISK CONSTRAINT 交易对手风险约束下的场外衍生品市场均衡模型
Q3 Economics, Econometrics and Finance Pub Date : 2018-11-12 DOI: 10.1142/S2282717X1850007X

In this study, we develop an equilibrium pricing model for an option contract with a counterparty risk, a collateral agreement, a counterparty risk constraint, and a threshold. Since we consider the option market to be an example of the derivatives market, we suppose that the buyer of an option has only countertparty risk of a seller defaulting. In addition, we consider a model where the buyer is allowed to enter into an option contract within an allocated amount of risk capital for counterparty risk, and requires (cash) collateral to the seller if the exposure exceeds the threshold. The counterparty risk is measured as a credit valuation adjustment. We provide an equilibrium pricing rule and an equilibrium volume formula by solving participants’ static utility-maximization problems. Based on numerical simulations, we verify the mechanisms through which collateralization, risk capital, and the threshold affect the size of the over-the-counter (OTC) option market. Finally, we analyze the influence of the buyer’s risk-aversion on the market, without collateralization. The results imply that the risk constraint might be a proxy for an investor’s attitude towards risk.
在本研究中,我们建立了一个包含交易对手风险、抵押品协议、交易对手风险约束和阈值的期权合约均衡定价模型。由于我们认为期权市场是衍生品市场的一个例子,我们假设期权的买方只有卖方违约的交易对手风险。此外,我们考虑了一个模型,其中买方被允许在交易对手风险的风险资本分配金额内签订期权合同,并且如果风险敞口超过阈值,则要求卖方提供(现金)抵押品。交易对手风险作为信用估值调整来衡量。通过求解参与者的静态效用最大化问题,给出了均衡定价规则和均衡体积公式。基于数值模拟,我们验证了担保、风险资本和阈值影响场外期权市场规模的机制。最后,我们分析了在没有担保的情况下,买方的风险厌恶对市场的影响。结果表明,风险约束可能是投资者对风险态度的代理。

VOLATILITY MEASURES, LIQUIDITY AND CREDIT LOSS PROVISIONS DURING PERIODS OF FINANCIAL DISTRESS 金融危机期间的波动性措施、流动性和信贷损失准备金
Q3 Economics, Econometrics and Finance Pub Date : 2018-07-03 DOI: 10.1142/S2282717X18500068
Giulio Anselmi
In this paper, we investigate the role of liquidity in banks lending activity and how liquidity provision is related to bank’s credit risk and others market-based risk measures, such as bank’s implied volatility skew from options traded on the market and realized volatility from futures contract on LIBOR, during periods of global financial distress. Credit risk is given by the ratio between loan loss reserves and total assets and we find that losses from lending activity force banks to build up new liquidity provisions only during the period of financial distress. Liquidity ratio is given by the sum of cash and short-term assets over total assets and we discovered that credit risk reduces liquidity ratio only in bad times, as this demand for liquid asset is suddenly switched on and the more reserves from loan losses the bank has, the more it cleans its balance sheet from long-term commitments in order to replenish its cash and short-term securities. When we control for market-based risk measures, we evidence that both implied volatility skew and LIBOR’s realized volatility are negatively related with the liquidity ratio and are useful in predicting a distress in bank’s liquidity holdings.
在本文中,我们研究了流动性在银行贷款活动中的作用,以及流动性供应如何与银行信用风险和其他基于市场的风险指标(如银行在市场上交易的期权的隐含波动率偏差和LIBOR期货合约的实现波动率)相关。信贷风险由贷款损失准备金与总资产之间的比率给出,我们发现贷款活动的损失迫使银行仅在财务困境期间建立新的流动性准备金。流动性比率是由现金和短期资产占总资产的总和给出的,我们发现信贷风险只在糟糕的时期降低流动性比率,因为这种对流动资产的需求突然开启,银行的贷款损失准备金越多,它就越会清理其资产负债表上的长期承诺,以补充其现金和短期证券。当我们控制基于市场的风险指标时,我们证明隐含波动率偏差和LIBOR的实现波动率与流动性比率呈负相关,并且有助于预测银行流动性持有的困境。

REWARD CULTURE AND BANKS’ PERFORMANCE DURING THE 2008 FINANCIAL CRISIS 2008年金融危机期间的奖励文化与银行业绩
Q3 Economics, Econometrics and Finance Pub Date : 2018-06-01 DOI: 10.1142/S2591768418500010

This paper explores the relationship between banks’ “reward culture” and banks’ performance and risk during the 2007–2008 financial crisis. Reward culture is defined as a result-oriented culture influenced through the incentives structure. Reward culture reflects three dimensions: (i) Chief Executive Officer incentives; (ii) Vice Presidents’ incentives; and (iii) employee incentives. A reward culture score represents the common factor in incentives across all employee levels. I find strong evidence of a nonlinear relationship between reward culture and bank returns and risk. Classifying banks into high, average, and low reward culture groups in the pre-crisis year 2006, I find that during the crisis period, banks within both the high and low reward culture groups performed worse, and were more risky than banks within the average reward culture group. The findings are consistent with the problems of adverse selection and moral hazard associated with incentive misalignment when incentives are too low or too high.
本文探讨了2007-2008年金融危机期间银行“奖励文化”与银行绩效和风险之间的关系。奖励文化被定义为受激励结构影响的结果导向文化。奖励文化反映了三个方面:(i)首席执行官的奖励;副总裁的奖励;(三)员工激励。奖励文化得分代表了所有员工级别激励的共同因素。我发现了强有力的证据,证明奖励文化与银行回报和风险之间存在非线性关系。我将2006年危机前的银行分为高、中、低回报文化组,发现在危机期间,高、低回报文化组的银行表现都比平均回报文化组的银行更差,风险更大。当激励过低或过高时,这些发现与逆向选择和道德风险相关的问题是一致的。

This paper models hedge fund exposure to risk factors and examines time-varying performance of hedge funds. From existing models such as asset-based style (ABS)-factor model, standard asset class (SAC)-factor model, and four-factor model, we extract the best six factors for each hedge fund portfolio by investment strategy. Then, we find combinations of risk factors that explain most of the variance in performance of each hedge fund portfolio based on investment strategy. The results show instability of coefficients in the performance attribution regression. Incorporating a time-varying factor exposure feature would be the best way to measure hedge fund performance. Furthermore, the optimal models with fewer factors exhibit greater explanatory power than existing models. Using rolling regressions, our customized investment strategy model shows how hedge funds are sensitive to risk factors according to market conditions.
本文建立了对冲基金风险敞口的模型,并考察了对冲基金的时变绩效。从现有的资产基础类型(ABS)因子模型、标准资产类别(SAC)因子模型和四因子模型中,根据投资策略提取出每个对冲基金组合的最佳6个因子。然后,我们发现风险因素的组合可以解释基于投资策略的每个对冲基金投资组合的大部分绩效差异。结果表明,性能归因回归的系数存在不稳定性。纳入时变因素敞口特征将是衡量对冲基金业绩的最佳方式。此外,因子较少的最优模型比现有模型具有更强的解释力。利用滚动回归,我们的定制投资策略模型显示了对冲基金如何根据市场条件对风险因素敏感。

DOES POST-IPO M&A ACTIVITY AFFECT FIRMS’ PROFITABILITY AND SURVIVAL? 上市后的并购活动是否会影响公司的盈利能力和生存?

In this paper, we investigate the post-IPO operating performance of acquiring companies listed in the US in the period 1986–2008. We find that acquiring IPO firms delivers better operating returns when compared to non-acquiring IPO firms in the five years after the listing. This result holds controlling for both IPO and firm-specific characteristics. Furthermore, acquiring targets already listed on the stock exchange and running stock deals are associated with the improved operating performance. Finally, we find that acquisitions also affect the newly listed companies’ survival, reducing both the time to failure and the time to being acquired, which suggest a structural acceleration of the “natural” company lifecycle.
本文研究了1986-2008年期间在美国上市的并购公司ipo后的经营绩效。我们发现,在上市后的五年内,收购IPO的公司比未收购IPO的公司提供了更好的运营回报。这一结果同时控制了IPO和公司的具体特征。此外,收购已在证券交易所上市的目标和进行股票交易与经营业绩的改善有关。最后,我们发现收购也会影响新上市公司的生存,既缩短了失败的时间,也缩短了被收购的时间,这表明公司“自然”生命周期的结构性加速。

We find that acquiring IPO firms delivers better operating returns when compared to non-acquiring IPO firms in the five years after the listing. This result holds controlling for both IPO and firm-specific characteristics. Furthermore, acquiring targets already listed on the stock exchange and running stock deals are associated with the improved operating performance. Finally, we find that acquisitions also affect the newly listed companies’ survival, reducing both the time to failure and the time to being acquired, which suggest a structural acceleration of the “natural” company lifecycle.","PeriodicalId":34440,"journal":{"name":"Journal of Financial Management Markets and Institutions","volume":"78 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72597218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
