基于BP神经网络的上市公司CEO报酬实证研究

近年来的研究表明,CEO报酬不仅受公司业绩的影响,还受到其他诸多因素的影响,而且,CEO报酬与其决定因素之间往往存在着非线性关系。本文以2003-2005年沪深股市的A股上市公司为样本,采用BP神经网络对CEO总报酬、CEO年薪、CEO持股价值及其决定因素分别进行训练和学习,结果表明:(1)网络训练输出值与实际值的拟合度分别达到91.09%、97.23%和78.44%;(2)网络的预测能力相对于传统的线性回归模型分别提高了92.72%、92.08%和53.89%。因此,本文认为在分析和确定CEO报酬水平时引入神经网络模型是可行的。     

Fresh in the saddle: The influence of a new CEO's vision and origin,and CEO succession type on market actors' reactions

CEO succession is a critical event in the life of a company. How external stakeholders respond to it, can affect the company's valuation. This study investigates how securities analysts' and investors' reactions to CEO succession are affected by the interplay between the charisma of the new CEO's vision, the new CEO's origin (whether an insider or outsider), and the type of CEO succession (whether routine, dismissal or interim). Drawing on the literature on signaling, we suggest that because a charismatic vision emits a positive signal about the company's future performance, it will affect market actors' reactions by either weakening or strengthening the influence of the signals emitted by other succession context contingencies, namely, CEO origin and succession type. To test our predictions regarding analysts' and investors' reactions, we respectively analyze panel data and conduct an event study. The results support most of our predictions. We discuss the study's contributions and implications.     

The micro-foundations of industrial diversification through foreign acquisitions: The multifaceted role of CEO experience

This paper examines the micro-foundations of cross-border industrial diversification strategies. We study the impact of observable CEO experience attributes on the propensity to acquire foreign target firms in unrelated (versus related) industries. Our findings, based on a sample of UK-based firms that engaged in cross-border acquisitions between 2010 and 2016, support an inverted U-shaped relationship between life experience of the CEO and the likelihood of engaging in unrelated foreign acquisitions. Further, we find that CEOs' broad-based work experience, across countries or industries, is associated with a higher propensity to engage in unrelated foreign acquisitions. Finally, CEOs’ education experience in MBA-type qualifications is associated with a preference for related foreign acquisitions. We discuss the theoretical implications of these findings and outline directions for future research in the context of micro-foundations in international business, strategic leadership, and upper echelons theory.     

董事会特征与总经理变更

本文以在上海证券交易所1999年前上市的公司为样本,研究董事会特征等治理变量对总经理变更的影响。研究结果表明,对相对业绩下降公司的总经理变更能起到显著解释作用的变量只有董事会会议的次数和公司的领导结构。而其它治理变量,诸如董事会规模、管理董事比例、独立董事比例、股权集中度、董事会成员持股比例等,未能对总经理变更起到显著的解释作用。     

基于传记特征的CEO继任财富效应研究

Executive Discretion and Corporate Performance as Determinants of CEO Compensation,Contingent on External Monitoring Activities

In this paper we discuss the potential impactof managerial discretion and firm performanceon CEO compensation, contingent on the extentof monitoring activities. We argue that CEOcompensation may be positively related toexecutive discretion and corporate performancefor firms that have vigilant external monitors. We alternatively contend that CEO compensationmay neither be associated with discretion norperformance for firms with passive externalmonitors. The empirical results are supportiveof our contentions.     

CEO satisfaction and intended strategic changes: The moderating role of performance cues

How do CEOs react to attainment discrepancies in their organizations' performance? Scholars have generally argued that (only) when performance falls below a certain aspiration level do CEOs intend to change the organization's strategy. However, empirical evidence on this issue is ambiguous and inconclusive. We address this puzzle directly by studying how CEOs' cognitive interpretations of performance (their satisfaction with the firm's performance) affect the magnitude of intended strategic changes, and we explore the moderating effect of the context (performance compared to the industry) on this relationship. Using a sample of medium-sized organizations, we find that CEOs' satisfaction with performance is negatively related to intended strategic changes, as expected, but only in contexts of poor performance compared to the industry. The negative relationship becomes less pronounced when performance compared to the industry reaches a certain threshold and even appears to reverse when the latter is extremely high. Moreover, exploratory post hoc analyses tentatively suggest the existence of two alternative intended change trajectories: contractive as a reaction to dissatisfaction and poor performance, and expansive as a response to satisfaction and high performance. These findings help to contextualize the effects of attainment discrepancies in light of conventional performance feedback theory and alternative theoretical perspectives.     

通胀对高管的股权激励和工作努力策略的影响

股权激励能够使得公司与高管的共同利益最大化,并且解决由于信息不对称所产生的委托代理问题。高管不可观测的工作控制着公司股票价格。由于高管的真实财富受到市场通胀不确定性的影响,本文研究了通胀环境下,以风险厌恶和工作努力效率为特质的高管,在银行无风险资产账户、市场投资组合和公司股票间寻求最优配置以达到个人终端真实财富预期效用最大化。首先利用伊藤公式得到了高管的真实财富过程;其次利用动态规划原理构建了满足最优工作努力策略和股权激励问题的哈密尔顿-雅可比-贝尔曼(HJB)方程,并找到了解析解;最后对结果进行了数值模拟,并从经济学的角度分析了通胀风险对高管的股权激励和工作努力策略的影响。本文研究表明:由于通胀不确定性影响着高管财富的实际价值,当高管财富效用服从对数函数时,公司股票占高管个人财富的最优比例不受通胀风险影响,但是高管在市场投资组合的投资比例随通胀波动率的增加而下降,进而影响到高管对市场投资组合账户和银行无风险资产账户的投资比例。高管的财富效用服从幂函数时,对于长期契约,股权激励代表的长远共同利益引导着高管看好公司的发展前景,激励着高管付出更高水平的努力,此时通胀带来的货币贬值风险对高管...

以CEO接班人年龄为视角,整合了组织行为理论、委托代理理论以及期望理论,研究了董事会成员遴选CEO接班人的决策机制以及这一机制对CEO继任后企业战略创新水平的影响.以1998～2011年发生CEO继任的中国A股上市公司为样本进行了实证检验,研究发现:CEO接班人年龄与公司董事会成员平均年龄同方向变化;董事会成员平均年龄与CEO接班人年龄的差距与CEO继任后企业的战略创新水平正相关.     

The influence of top management corporate networks on CEO succession

We analyze empirically how supervisory board members with multiple directorships affect the decision to hire an inside or outside CEO successor. While a growing number of both theoretical and empirical studies analyze the influence of corporate performance and size or the ownership structure on this decision, the role of multiple board memberships within the CEO recruitment process has been widely neglected so far. The present study is based on panel data of the largest German companies covering the period from 1996 to 2008. Applying competing risk estimations we find a weak and positive association between the number of external directorships of the supervisory board members and internal CEO replacements. Distinguishing between different groups of external board positions, we find that external executives on the supervisory board increase the likelihood of external CEO replacements. In line with empirical findings for the US we argue that external executives improve the assessment of potential CEO successors leading to more outside CEO replacements. In contrast, we find evidence that external supervisory board mandates of the supervisory board members cause more internal CEO replacements. This finding indicates a substitution of external expertise of the executives by multiple supervisory board mandates but could also reflect a reduction of the monitoring intensity of the supervisory board.     

基于中国上市公司的CEO更替与公司治理有效性研究

以中国上市公司为样本,采用2002～2005年的数据,从CEO更替的视角检验了中国公司治理的有效性.实证结果表明:中国的公司治理是有效的,即企业绩效差的CEO更可能被更换,但是这种有效性与正式制度安排的公司治理机制并不相关,这可能是非正式制度的公司治理机制发挥了重要作用.     

CEO duality and firm performance: The moderating roles of other executives and blockholding outside directors

This study examines how the effect of CEO duality on firm performance is affected by two internal governance forces – namely other executives in the top management team and blockholding outside directors. Results based on a longitudinal dataset from the U.S. computer industry were consistent with my hypotheses. Specifically, I found that the effect of CEO duality was negative when the CEO had dominant power relative to other executives and when the board had a blockholding outside director, but was nonsignificant otherwise. This study enriches our understanding of the effect of CEO duality, and helps reinforce the call for the nonduality structure as the default choice and put the burden of proof on those who wish to justify otherwise on special grounds.     

The Moderating Role of Power Distance on the Reaction of Consumers to the CEO as a Spokesperson During a Product Harm Crisis: Insights From China and South Korea

During a crisis the corporate message is not the only issue facing the company. The role of the spokesperson is an under-researched area which is examined in this paper. In studies conducted in South Korea and China we examine the reaction of consumers to the CEO as a spokesperson during a product harm crisis. We find in both countries that consumer responses to the CEO was contingent on the consumers' level of power distance. When consumers had high levels of power distance they had higher future purchase intentions when compared with consumers who had low levels of power distance when the CEO was the spokesperson during the crisis. In addition, in a study conducted in South Korea we find that higher levels of power distance generate increased levels of brand trust when the CEO is the spokesperson, which in turn increases future purchase intentions. Our studies have important theoretical and managerial implications which are discussed in the paper.     

Board leadership structure and diversity over CEO time in office: A test of the evolutionary perspective on Italian firms

An evolutionary perspective on CEO-board relations suggests that CEO objectives and interests change over time, and that board roles should shift accordingly, from CEO leadership development during the early stages of CEO time in office toward monitoring during the latest stages. This study examines how two board characteristics, board leadership structure and board diversity, shape innovation investment among Italian firms. Empirical results support the hypothesized effects, suggesting that the board’s effects are contingent upon CEO time in office.     

终极所有权结构对权益资本成本的影响——来自中国上市公司的经验证据

采用三种模型(GLS模型、ES模型和OJ模型)度量上市公司权益资本成本,以2004-2007年连续4年均能获得相关资料的中国非金融类上市公司构成的面板数据为研究样本,在控制相关变量下,基于代理成本和信息不对称视角实证检验终极所有权结构与权益资本成本之间的关系.研究发现,终极所有权结构是影响权益资本成本的重要因素之一.具体而言:(1)现金流量权与权益资本成本显著负相关;(2)控制权和现金流量权的分离度与权益资本成本显著正相关;(3)与终极控股股东是非国有控股的公司相比,终极控股股东是国有控股的公司具有相对高的权益资本成本.     

Top management team diversity and ambidexterity: The contingent role of shared responsibility and CEO cognitive trust

Earlier research has suggested that diversity is a double-edged sword when achieving organizational ambidexterity. While it may contribute to the development of new combinations of exploration and exploitation, it may also lead to disagreements and potential conflict within top management teams (TMTs). To improve our understanding of the effectiveness of diversity in ambidextrous organizations, we develop a synergistic perspective on TMT diversity and examine how two types of diversity – functional and age diversity – affect the achievement of organizational ambidexterity. We also identify shared responsibility and CEO cognitive trust as important contingencies that may complement the effects of diversity within TMTs in terms of resolving potential conflicts and managing tensions between exploration and exploitation effectively. Based on multisource data, our study shows that CEO cognitive trust and shared responsibility moderate the relationship between different types of diversity and ambidexterity. Our study has important implications for research on organizational ambidexterity, diversity, and senior leadership.     

承销商变更对股权再融资的影响:理论与实证

从理论和实证两方面,研究上市公司股权再融资(SEO)时是否更换承销商的决策问题以及承销商变更对上市公司资本市场表现的影响.理论模型表明,当承销商和发行公司之间存在较为严重的信息不对称,即在首次公开发行(IPO)时,不同资产质量的公司都能获得高声誉承销商承销;而当发行公司和承销商对彼此状况了解更为深入,即SEO时,高声誉承销商能识别不同公司的资产质量,出于对自身声誉的维护,不再承销低资产质量的公司,此时低资产质量的公司只能选择低声誉的承销商.实证结果与理论模型相符合,实证发现:相对于质量好的公司,质量差的公司在SEO时被迫更换承销商的概率更高.更换组公司与未更换组公司在IPO时雇佣的承销商声誉没有显著差别,而更换组公司在SEO时雇佣的承销商声誉明显较差.进一步探究承销商变更对公司市场表现的影响时,发现相较于更换了IPO承销商的公司,未更换承销商的公司在SEO时能够获取更低的折扣率和更高的长期股票回报率,这一结果在多种测试下都是稳健的.     

The influence of executive age,career horizon and incentives on pre-turnover earnings management

In this paper we hypothesize that CEOs will be motivated to manage earnings prior to a turnover decision. This motivation comes from the horizon problem for CEOs nearing retirement age and for CEOs whose profit-based bonus is a large portion of their total compensation. We find that firms in which CEOs are nearing retirement age have large discretionary accruals in the year prior to turnover. Although we find firms with a larger proportion of profit-based bonus pay have larger discretionary accruals, this result is not robust with the inclusion of control variables in the regressions.

The Relative Effects of Different Frequencies of Feedback on Work Performance

Abstract

This laboratory simulation examined the relative effects of two frequencies of feedback on work performance under hourly pay and incentive pay. The study had four experimental conditions: feedback delivered after every session under hourly pay and under incentive pay, and feedback delivered after every fourth session under hourly pay and under incentive pay. Thirty-five college students were randomly assigned to one of the four conditions. Each participant attended 24 thirty-minute sessions. Participants performed a simulated work task on the computer that consisted of computer-related activities such as dragging, clicking, and typing. The dependent variable was the number of correctly completed units of work. An analysis of covariance was conducted to analyze the data using pretest scores as a covariate. Participants who received feedback every session completed significantly more work units than participants who received feedback every fourth session. In addition, an interaction between feedback frequency and pay systems was found: Feedback delivered every session was more effective than feedback delivered every fourth session under the incentive pay system, but not under the hourly pay system. The results suggest that the relative effects of feedback frequency may depend upon the extent to which feedback is correlated with differential consequences for performance.
