CEO年龄、公司风险与风险决策行为

选取2007~2012年沪深 A 股上市公司的 CEO 为研究对象,探讨 CEO 年龄对上市公司市场风险和公司风险决策特征的影响。实证发现：CEO 年龄越大,其所在公司的市场风险越小。进一步研究表明：老年 CEO 主要通过低风险决策行为来减少公司的市场风险,即：老年 CEO 在研发上投资较少,其公司经营杠杆比率以及过度投资程度相对较低。这一结论对于我们更好地理解老年 CEO 的风险决策行为,及对不同风险特征的上市公司如何聘请不同年龄的新 CEO 具有一定的启示意义。     

Do CEOs Matter? Evidence from Hospitalization Events

Using variation in firms’ exposure to their CEOs resulting from hospitalization, we estimate the effect of chief executive officers (CEOs) on firm policies, holding firm-CEO matches constant. We document three main findings. First, CEOs have a significant effect on profitability and investment. Second, CEO effects are larger for younger CEOs, in growing and family-controlled firms, and in human-capital-intensive industries. Third, CEOs are unique: the hospitalization of other senior executives does not have similar effects on the performance. Overall, our findings demonstrate that CEOs are a key driver of firm performance, which suggests that CEO contingency plans are valuable.     

The acquisitiveness of youth: CEO age and acquisition behavior

I demonstrate that acquisitions are accompanied by large, permanent increases in Chief Executive Officer (CEO) compensation, which create strong financial incentives for CEOs to pursue acquisitions earlier in their career. Accordingly, I document that a firm's acquisition propensity is decreasing in the age of its CEO: a firm with a CEO who is 20 years older is ∼30%$\sim 30\%$ less likely to announce an acquisition. This negative effect of CEO age on acquisitions is strongest among firms where CEOs likely anticipate or can influence high post-acquisition compensation, and is absent for other investment decisions that are not rewarded with permanent compensation gains. The age effect cannot be explained by the selection of young CEOs by acquisition-prone firms, nor by a story of declining overconfidence with age. This paper underscores the relevance of CEO personal characteristics and CEO-level variation in agency problems for corporate decisions.     

Seeking safety: The relation between CEO inside debt holdings and the riskiness of firm investment and financial policies

CEO inside debt holdings (pension benefits and deferred compensation) are generally unsecured and unfunded liabilities of the firm. Because these characteristics of inside debt expose the CEO to default risk similar to that faced by outside creditors, theory predicts that CEOs with large inside debt holdings will display lower levels of risk-seeking behavior (Jensen and Meckling, 1976). Consistent with the theoretical predictions, we find a negative association between CEO inside debt holdings and the volatility of future firm stock returns, R&D expenditures, and financial leverage, and a positive association between CEO inside debt holdings and the extent of diversification and asset liquidity. Collectively, our results provide empirical evidence suggesting that CEOs with large inside debt holdings prefer investment and financial policies that are less risky.     

CEO incentive compensation and stock price momentum

We document strong evidence that CEO incentive compensation can predict the significance of stock price momentum through discretionary accrual and real activities manipulation. The profit of momentum strategy increases with CEO pay-for-performance incentive, but decreases with CEO risk-taking incentive. It also evaluates the effects of information uncertainty on such relationship. The evidence is more significant for firms with older and longer tenured CEOs and firms with more informed traders. The relationship between the profit of momentum strategy and CEO pay-for-performance incentive is stronger among CEOs without the risk-taking incentive. Our results are robust for different sub-samples based on before and after Reg FD and Sarbanes–Oxley Act, even after controlling for the potential endogeneity. Further, our findings are consistent with the information diffusion explanation of momentum and the agency theory that incentivised CEOs tend to manipulate information by smoothing good news, concealing mildly bad news and accelerating the disclosure of extremely bad news.     

Silverback CEOs: Age,experience, and firm value

Approximately half of S&P 1500 firms have adopted policies mandating retirement based on age. This study investigates the merits of CEO mandatory retirement policies (MRPs) using a sample of 12,610 firm-year observations from 2143 unique firms. It also addresses the question of whether CEO age is relevant to the success of an organization. We fail to find consistent evidence that MRPs are intended to limit CEO entrenchment. MRPs are, however, positively associated with CEO age and negatively associated with firm-specific human capital. Further analysis reveals that CEO age is significantly negatively related to firm value, operating performance, and corporate deal-making activity. Splitting our sample according to whether an MRP is in place, we observe that the negative impact of age exists only for those firms which do not have MRPs. We therefore conclude that MRPs represent an effective form of firm governance designed to mitigate the underperformance of older CEOs.     

Do younger CEOs really increase firm risk? Evidence from sudden CEO deaths

This study uses sudden deaths of CEOs to provide causal evidence on the relation between CEO age and firm risk. I find that CEO age negatively influences firm risk, measured by stock return volatility, but has no effect on policy choices related to risk taking. These findings contrast prior studies, and suggest that the higher volatility is caused by uncertainty about the younger replacement CEOs' contribution to firm value, rather than changes to risk-related corporate policies.     

CEO age and tax planning

This study investigates the association between CEO age and corporate tax planning. Using a sample of 11,537 firm‐year observations from the fiscal year 1997–2013, I find CEO age exerts an economically significant influence on firms’ tax policies, incremental to economic determinants identified in prior research. Specifically, CEO age is positively related to cash and GAAP effective tax rates, and negatively related to permanent book‐tax difference, suggesting that older CEOs are less likely to take actions to lower tax burden. The results hold across different model specifications and robustness tests to address potential bias arising from endogeneity, sample selection issue, and the confounding effect of CEO tenure.     

The Young and the Restless: A Study of Age and Acquisition Propensity of CEOs of UK Firms

Using a large sample of CEOs of UK firms, we show that CEO age is a key determinant of acquisition activity. We find that younger CEOs are more likely to acquire another firm and spend more on large capital expenditures. We argue that while younger CEOs of both UK and US firms undertake more acquisitions than their older peers, their motivations for acquisitions might differ. We find that the stock market perceives acquisitions by younger CEOs to be of a higher quality. Following previous studies, we use CEO tenure as a proxy for reputation, and find that large acquisitions enhance CEO reputation, especially for younger CEOs. In contrast to the previous findings for CEOs of US firms, we determine that the compensation of CEOs in the UK does not increase after acquisitions. This absence of a compensation incentive for CEOs of UK firms is consistent with the idea that the UK compensation structure is more restrictive and has a smaller equity‐based component. Our evidence is also inconsistent with an overconfidence effect. Overall, our results provide consistent evidence of executive signaling by younger CEOs of UK firms eager to distinguish themselves.     

Are bonds blind? Board-CEO social networks and firm risk

We examine the impact of social networks between independent directors and the CEO on firm risk. Employing the deaths and retirements of socially connected independent directors and the passage of the 2002 Sarbanes-Oxley Act for two identifications, we find that board-CEO social networks have a positive impact on firm risk. Specifically, CEOs who are socially connected to their independent directors are motivated to adopt riskier investment, operating and financing strategies. This positive influence is more pronounced for prior under-performing firms and for CEOs with low power or overconfidence, indicating that board-CEO social networks act as career insurance and a power-enhancing mechanism to encourage managerial risk-taking.     

Organizational complexity and CEO labor markets: Evidence from diversified firms

We examine whether CEO turnover and succession patterns vary with firm complexity. Specifically, we compare CEO turnover in diversified versus focused firms. We find that CEO turnover in diversified firms is completely insensitive to both accounting and stock-price performance, but CEO turnover in focused firms is sensitive to firm performance. Diversified firms also experience less forced turnover than focused firms. Following turnover, replacement CEOs in diversified firms are older, more educated, and are paid more when hired. Collectively, our results indicate that the labor market for CEOs is different across diversified and focused firms and that firm complexity and scope affect CEO succession.     

When CEOs adapt: An investigation of manager experience,policy and performance following recessions

We examine changes in corporate policies following recessions during CEO tenures to evaluate the value of learning. CEOs with recession experience demonstrate expertise in risk-shifting strategies that can contribute to higher firm value and performance during subsequent recessions. Specifically, Recession CEOs use conservative capital structure and allocation during expansions, providing excess capacity and financial slack to accumulate additional cash reserves during economic contractions, resulting in lower bankruptcy risk. As a result, Recession CEOs are equipped to raise more capital in recessions, which results in higher asset growth fueled by investments in acquisitions and capital expenditures. We also examine prior recessions and find poor performers learn to invest more and perform better in subsequent contractions. Our results are strengthened through cumulative recession experiences, when downturns are deeper, and at cyclical firms, where economic cycles are most impactful and Recession CEOs are more relevant. Finally, we use time-varying industry downturns, matching, and CEO turnovers for inference. Overall, we offer novel evidence of valuable CEO learning around risk-taking following direct managerial experience as a firm policy determinant across economic conditions.     

Measuring R&D curtailment among short-horizon CEOs

I review evidence produced by prior literature on CEO horizon problems and show that prior empirical findings are correlated with the research design employed. I find that evidence of R&D curtailment by CEOs as they approach retirement stems predominantly from cross-sectional correlations between CEO age or tenure and R&D spending. Using a broad sample of CEOs of S&P 1500 firms, I identify two factors that confound the cross-sectional relationship of firm R&D spending on CEO age or tenure which can lead to spurious inferences regarding the CEO horizon problem. I find that tracking R&D spending by the same CEOs over time produces no evidence of R&D curtailment. These results have research design implications for future researchers investigating the impact of shortened CEO career horizons on investment myopia.     

Love or money: The effect of CEO divorce on firm risk and compensation

I find lower firm risk in the year of a CEO divorce. This lower volatility is consistent with a reduction in risk incentives, as CEOs pay large divorce settlements and are less able to diversify firm-specific risk from their portfolios. Divorce has a larger impact on firms with cash-poor CEOs who lack diversification. Cash flow and accruals have lower volatility in the year of divorce, which is likely due to smoother discretionary expenses. The sensitivity of compensation to both price and volatility is significantly higher after divorce, suggesting compensation incentives adjust to portfolio incentives, with total compensation increasing by over $2 million on average. I find no evidence the results relate to increased distraction or alternative explanations.     

Corporate social responsibility and inside debt: The long game

We examine the effect of CEO inside debt on corporate social responsibility (CSR). We document a positive relation between CEO inside debt and CSR. This positive relation is attenuated not only when firms face high risk, but also when firms have high short-term institutional ownership. Our evidence supports the view that CEOs with large inside debt holdings are more concerned about firm sustainability and, are therefore more likely to prefer CSR for long-term firm benefits, i.e., the long game. We also find that CSR and CEO inside debt jointly exert a significantly positive impact on long-run stock performance, particularly in the presence of a low level of short-term institutional holdings. Overall, our findings highlight the importance of aligning institutional investor preferences with CEO incentives in order to maximize shareholder benefits from CSR investment.     

Why do firms appoint CEOs as outside directors?

Companies actively seek to appoint outside CEOs to their boards. Consistent with our matching theory of outside CEO board appointments, we show that such appointments have a certification benefit for the appointing firm. CEOs are more likely to join boards of large established firms that are geographically close, pursue similar financial and investment policies, and have comparable governance to their own firms. The first outside CEO director appointment has a higher stock-price reaction than the appointment of another outside director. Except for a decrease in operating performance following the appointment of an interlocked director, CEO directors do not affect the appointing firm's operating performance, decision-making, and CEO compensation.     

Are long-tenured CEOs rent seekers? Analysis of cash compensation and post disposal performance

Are typical long-tenured CEOs rent-seekers? Do compensation committees consider undiversified risk for veteran executives and design their cash pay to limit their risk exposure? Because an exit decision requires board approval, discontinued operations provide a unique setting to analyze intervention by compensation committees. Seasoned managers should require less oversight because their ability has been revealed over time. However, as CEOs advance in their careers, they are more likely to acquire power to influence board decisions. They are also more risk averse and potentially more myopic than younger CEOs because they hold a large undiversified portfolio. Lucrative labor markets for talented retired executives can incentivize long-tenured CEOs to maintain a solid reputation. I reexamine the previously reported differential sensitivity of CEO cash compensation to positive or negative-valued disposal decisions, which can be viewed as rent-seeking. I show that cash pay for veteran CEOs are shielded from the effect of both negative and positive-valued discontinued operations, suggesting that compensation committees alter their cash pay. This evidence does not support rent-seeking. I also find strong evidence that long-tenured CEOs make better exit decisions to improve future firm performance than less experienced executives.     

CEO DIRECTORS,EXECUTIVE INCENTIVES,AND CORPORATE STRATEGIC INITIATIVES

I study how directors who are chief executive officers (CEOs) of other firms affect board effectiveness. I find that CEOs are paid more and their compensation is less sensitive to firm performance when other CEOs serve as directors. This is not an employment risk premium because CEO directors are not associated with higher turnover‐performance sensitivity. Also, CEO directors have no effect on corporate innovation but are associated with higher acquisition returns, especially for complex deals. My results suggest that the advisory benefits of CEO directors must be balanced against the distortions in executive incentives associated with their board service.     

CEO gender and managerial entrenchment

This paper investigates the effect of gender on managerial authority and control over firms. The study examines S&P 1500 firms for the period of 1999–2014. Our findings suggest that accounting performance, firm value, CEO age, firm age, and board size reduce the likelihood of appointing female managers. On the other hand, the appointment of female CEOs is directly associated with the percentage of female directors, board independence, and beta. The study confirms the notion that female CEO appointments are generally associated with firms facing adverse conditions, and shows that female CEOs are more entrenched as compared to male CEOs. We find that the presence of female CEO decreases the turnover-performance sensitivity, increases the E-index, and inflates CEO compensation. Our research suggests that the level of female CEOs’ entrenchment provides them with greater job security, higher level of control, and inflated pay that compensate the risk of accepting the appointment in a high risk and poor performing firm.     

CEO discretionary power,unconstrained stock ownership,and stock trading: Theory and evidence

This paper examines CEOs' holding and trading of unconstrained firm stock they own, i.e., vested and sellable firm shares. I first develop a theoretical model of why CEOs hold sellable shares in their own firm when doing so is riskier than holding a more diversified portfolio. In this model, greater stock ownership allows the CEO to exercise discretionary power more easily and extract rents from the company. My model predicts that CEOs desire to hold more firm stock and therefore are less likely to sell stock when they have greater discretionary power. This empirical prediction is supported by tests that measure discretionary power based on the principal component analysis of three proxies. Using stock trading data in S&P 1500 firms, I find that discretionary power is negatively (positively) associated with the CEO's stock sale (purchase). The results are weaker in industries where rent extraction is more difficult. Further, results hold for both founder and non-founder CEOs, and are robust to a battery of sensitivity tests. Overall, this study provides new insights concerning CEOs' decisions to own their companies' stock.
