股票期权行权价格的局限与修订研究

股票期权计划在国内外受到广泛关注,并日益成为公司经理人激励的主要手段。但由于我国股票市场的弱式性,以股价为基础的股票期权并不能真正反映经理人的业绩表现。为此,本文引入超额EVA增长率和行业股票价格参数对现行以股票价格为基础的股票期权行权价格进行修订,以使经理人的激励报酬和业绩贡献变动相结合。与此同时,本文还引入行业分类指数变动率以消除股市波动对行权日行权价格的影响。调整后的行权价格更加真实的反映了经理人的业绩。论文最后指出该方案所具有的优势,认为经过修订的股票期权行权价格在我国更具有现实意义。     

Managerial risk-taking incentives and non-GAAP earnings disclosures

We investigate the association between risk-taking incentives provided by stock-based compensation arrangements and non-GAAP financial disclosures. Controlling for compensation to stock price sensitivity, we find that managers with higher compensation to stock volatility sensitivity (vega) are more likely to be associated with voluntary non-GAAP earnings information disclosures. In addition, higher-vega managers are found to be associated with more frequent and less opportunistic non-GAAP earnings information disclosures. Robust to alternative specifications and estimations, our findings suggest that compensation arrangements can encourage managers to make more, higher-quality voluntary non-GAAP disclosures.     

Stock price informativeness on the sensitivity of strategic M&A investment to Q

Using a strategic merger sample that covers the period from 1985 to 2011, we find that the acquirer’s stock price firm-specific information, the new information created by investors about the value of firm fundamentals, increases the positive sensitivity of strategic merger investment to the acquirer’s Q; the target’s stock price firm-specific information increases the negative sensitivity of merger investment to the target’s Q. These results suggest that managers learn from financial markets in identifying strategic merger investment opportunities by transferring assets from poorly managed firms to well managed firms. In addition, the target’s stock price firm-specific information itself increases the acquisition size, indicating that informed acquirer managers are more likely to take out large merger investment. Last but not the least, stock price informativeness increases merger synergies and post-merger performance, suggesting that informed managers make better merger investment that increases shareholder value. Our study contributes to the recent increasing stream of studies on managerial learning from the market.     

Stock price firm‐specific information on the choice of stock payment in mergers and acquisitions

Previous studies on the choice of stock payment in M&A mainly focus on managerial private information. This study shows that managers also learn new firm‐specific information from financial markets in making this decision. The acquirer's stock price firm‐specific information increases the stock‐payment‐to‐Q sensitivity. The target's stock price firm‐specific information decreases the stock payment probability. Further analyses on deal and firm characteristics as well as shareholder wealth in stock mergers support the managerial learning argument. Overall, this study highlights a new set of information that affects the form of merger payment in mergers and acquisitions.     

Director compensation incentives and acquisition performance

This paper investigates the relation between director compensation structure and shareholder interests in the context of acquisitions. Our evidence suggests that acquirer firms that compensate their directors with a higher proportion of incentive-based compensation have significantly higher stock returns around the announcement. Compared to acquirers in the low equity-based compensation group, acquirers in the high equity-based compensation group outperform by 9.54% in a five-day period surrounding the announcement date. These results hold even after controlling for endogeneity issues. We further find that acquirers with higher equity-based pay exhibit greater improvements in stock price and operating performance in the three years following acquisitions. An increase in director equity-based pay also results in a lower acquisition premium for targets. These results indicate that equity-based compensation provides incentives for directors to make decisions that meet the interests of shareholders.     

Stock‐Based Compensation in a Concentrated Ownership Setting: An Empirical Investigation

Stock‐based compensation has been viewed as an important mechanism for tying managers’ wealth to firm performance, and thus alleviating the agency conflict between the shareholders and the managers when ownership is diffused. However, in a concentrated ownership structure, controlling owners are usually the management of the firm; they can engage in self‐dealing activities to the detriment of minority shareholders’ interests. Yet, outside investors may anticipate the problem and discount the share price for the entrenchment behaviors they observe. In this study, we investigate how controlling owners trade off the benefits and the costs of using stock‐based compensation. Based on a sample of Taiwanese firms, our evidence shows that stock‐based compensation is negatively related to the agency problem embedded in a concentrated ownership structure. This relationship is evident among firms with more frequent equity offerings. Overall, our empirical evidence suggests that controlling owners consider the negative price effects of stock‐based compensation and trade off these costs with the benefits of expropriating minority shareholders’ interests, particularly when firms seek more external equity capital. Our results hold after controlling for selection bias and share collateral by controlling owners.     

Managing earnings surprises in the US versus 12 other countries

We compare the distribution of earnings surprises in the US to those of 12 other countries. We expect US managers to be relatively more likely to manage earnings surprises due to differences in US corporate governance and legal environments versus those in other countries. An increasing emphasis on stock price performance in the US, as reflected by the rapid increase in stock and options compensation to US managers, and increases in litigation upon stock price drops, leads us to expect the tendency of US managers to manage earnings surprises versus those of non-US managers has increased in recent years. Our evidence is consistent with our expectations. We discuss the implications of our findings for public policies to address the earnings surprise game.     

Equity Issuance and Adverse Selection: A Direct Test Using Conditional Stock Offers

We conduct a unique test of adverse selection in the equity issuance process. While common stock is the dominant means of payment in bank mergers, stock acquisition agreements provide target shareholders with varying degrees of protection against adverse price movements in the bidder's stock between the time of the merger agreement and the time of merger completion. We show that it is the degree of protection against adverse price changes and not the percent of stock offered in a bank merger that explains bidder merger announcement abnormal returns. This result is difficult to explain outside of an adverse selection framework.     

Letting Go of Norm: How Executive Compensation Can Do Better Than "Best Practices"

With executive pay under the media spotlight, the corporate search for “best practices” is in reality a drive toward common practices as cautious boards gravitate toward a safe norm. But are current trends in compensation structure as good for shareholders as they are for the consultants who implement them? This article explores some of these trends and derives some conclusions about their role in shareholder value creation based on detailed data on executive plans and stock price performance for the S&P 500. One key finding is that rewarding managers for profit growth produces higher stock price returns than rewards based on multiple measures or balanced scorecards. Also, the popular practice of adding long‐term incentive plans to the compensation mix does not appear to improve long‐term performance. Finally, the granting of equity based on the past year's performance rather than in annual fixed‐value amounts appears to be good for shareholders because of additional incentives created by performance‐based grants as well as the elimination of the perverse incentive of rewarding poor stock price performance with more shares.     

Professors in the Boardroom and Their Impact on Corporate Governance and Firm Performance

We find that companies with directors from academia are associated with higher performance. This relation is driven by professors without administrative positions. We also find that academic directors play an important governance role through their advising and monitoring functions. Specifically, our results show that the presence of academic directors is associated with greater acquisition performance, a higher number of patents and citations, higher stock price informativeness, lower discretionary accruals, lower chief executive officer (CEO) compensation, and higher CEO forced turnover‐performance sensitivity. Overall, our results indicate that academic directors are valuable advisors and effective monitors and firms benefit from having academic directors.     

Equity‐Based Compensation for Employees: Firm Performance and Determinants

I examine the effect of employee equity‐based compensation (EBC) on firm performance and the determinants of EBC. Using two samples, I find that firms have come to rely more heavily on EBC than in the past. For both samples, I document a significant, positive relation between Tobin's q and the percentage of employee compensation that is equity based. For accounting returns, I find a positive relation with the earlier sample. However, for the later sample I find that greater use of EBC leads to lower levels of future accounting returns. I also find that the determinants of the proportion of EBC are different between the two samples.     

Incentive Compensation and the Stock Price Response to Dividend Increase Announcements

Linking executive compensation to stock price performance is predicted to decrease the usual positive price response to dividend increases for two reasons. One, increasing pay‐performance sensitivity (PPS) exacerbates managers' optimistic bias regarding future firm performance, reducing the credibility of dividend signals. Two, increasing pay‐performance sensitivity reduces the need for dividends as a means of reducing agency costs. Consistent with behavioral and agency theories of corporate finance, we find that price response does decrease as pay‐performance sensitivity increases and that this effect is concentrated in firms with low market‐to‐book ratios. Additional findings are most consistent with the agency cost explanation.     

ALIGNMENT EXPOSED: HOW CEOS ARE PAID, AND WHAT THEIR SHAREHOLDERS GET FOR IT

This article begins by arguing that, for many companies, there is a significant "disconnect" between how managers are paid and what is actually achieved for shareholders. This paper answers two questions of prime importance to investors: Is there a way to know beforehand whether managers' incentives are well aligned with those of its shareholders? And does such alignment actually make a difference in the returns one is likely to see?
In answering the first question, the author argues that cash bonuses and performance-based equity grants (i.e., grants based on managers' meeting accounting-based operating targets) are likely to provide stronger, more cost-effective incentives than grants of stock or options because the former are generally based on measures over which managers have significantly more control than the stock price. Using this insight, the author develops a method for evaluating compensation structures based on the variability of compensation, the number and type of compensation metrics purportedly driving that variability (including the award of performance shares or options), the stability of those metrics over time, and the apparent level of discretion in the use of those metrics to either fund or distribute bonuses (including equity). All these elements are disclosed to varying degrees in the proxy statements or annual reports of companies.
Using his compensation scores for 140 companies and their return history over the last eight years, the author concludes that "high alignment" companies outperform their "low alignment" peers by more than 5% per year in total shareholder returns. Furthermore, increases in alignment scores by individual companies over time tend to lead to higher total shareholder returns, and degradation of scores lead to lower returns. In short, observable improvements in compensation structure appear to pay off in the form of significant abnormal returns.     

Earnings management and initial public offerings: Evidence from the Netherlands

This paper presents one of the first studies of earnings management by initial public offering (IPO) firms in a European country. Using a sample of 64 Dutch IPOs, we investigate the pattern of discretionary current accruals (DCA) over time. We find that managers manage their company's earnings in the first year as a public company but not in the years before the IPO. We also examine the impact of earnings management on the long-run stock price performance of IPOs. We find a negative relation between the size of the DCA in the first year as a public company and long-run stock price performance over the next 3 years. A number of additional tests support these findings.     

Transfer Pricing, Incentive Compensation and Tax Avoidance in a Multi-Division Firm

This article examines the relation between transfer pricing and production incentives using a model of a vertically integrated firm with divisions located in different tax jurisdictions. We show that if divisional profits are taxed at the same marginal rate, the transfer price should be set to minimize the compensation risk faced by the manager of the buying division. For the case where divisional profits are taxed at different marginal rates, we are able to characterize the trade-off between the tax savings from setting transfer prices to reduce profitability in the high tax jurisdication and the loss of effort attributable to the impact of tax avoidance on the incentive compensation system. Further, we show that if it is feasible to compensate the division managers using multiple performance measures, the transfer price should be used to minimize the firm's overall tax liability. Finally, we show that when authority to determine the transfer price must be delegated to one of the division managers, it is optimal to assign responsibility for setting the transfer price to the manager of the division with the most production uncertainty.     

Corporate Performance,Corporate Governance and Top Executive Turnover in Finland

This paper empirically investigates how corporate governance forces and firm performance affect top executive turnover in Finnish listed companies. I document an increase in CEO, top management, and board turnover in response to poor stock price performance and operating losses. The sensitivity of the relation between stock price performance and CEO turnover is significantly higher in firms with a two‐tier board structure (when the CEO is not the chairman), but significantly lower when the CEO or a board member is the controlling shareholder. These results suggest that both the ownership structure and the board design have implications for the disciplining of managers.     

Accounting behavior of German firms after an ADR issuance

This paper presents preliminary evidence on whether German corporations that issue American depositary receipts (ADR) experience a change in the level of garbling in earnings as expressed under German Generally Accepted Accounting Principles (GAAP). In a shareholder regime, a manager's objective is to maximize the company's stock price. Past literature suggests that this will lead managers to follow a policy of more disclosure. In stakeholder regimes, managers have an ill-defined objective function and their compensation is not typically sensitive to the price of the stock. This literature suggests that managers in stakeholder regimes will manipulate earnings to satisfy the various constituents of the firm. By issuing an ADR, a company changes its regime: shareholders become relatively more important to the manager. To maximize the stock price, managers should minimize the overall noise in accounting numbers even under local GAAP. The empirical results are generally consistent with this hypothesis, but a small sample size prevents drawing definitive conclusions.     

An Analysis of the Relation between the Stewardship and Valuation Roles of Earnings

In this paper, we seek a deeper understanding of how accounting information is used for valuation and incentive contracting purposes. We explore linkages between weights on earnings in compensation contracts and in stock price formation. A distinction between the valuation and incentive contracting roles of earnings in Paul [1992] produces the null hypothesis that valuation earnings coefficients (VECs) and compensation earnings coefficients (CECs) are unrelated. Our empirical analyses of the relations between earnings and both stock prices and executive compensation data at the firm and industry levels over the period 1971–2000 rejects Paul's [1992] hypothesis of no relation. We also document an increasing weight over time on other public performance information captured by stock returns in the determination of cash compensation. Specifically, we find that the incentive coefficient on returns is significantly higher in the second of two equal sample subperiods relative to the incentive coefficient on earnings.     

The role of the media in corporate governance: Do the media influence managers' capital allocation decisions?

Using 636 large acquisition attempts that are accompanied by a negative stock price reaction at their announcement (“value-reducing acquisition attempts”) from 1990 to 2010, we find that, in deciding whether to abandon a value-reducing acquisition attempt, managers' sensitivity to the firm's stock price reaction at the announcement is influenced by the level and the tone of media attention to the proposed transaction. We interpret the results to imply that managers have reputational capital at risk in making corporate capital allocation decisions and that the level and tone of media attention heighten the impact of a value-reducing acquisition on the managers' reputational capital. To the extent that value-reducing acquisition attempts are more likely to be abandoned, the media can play a role in aligning managers' and shareholders' interests.     

Information-based stock trading and managerial incentives: evidence from China's stock market

This paper uses stock price informativeness, or information-based stock trading, to help explain the pay–performance sensitivity (PPS) of chief executive officer (CEO) compensation in China's listed firms. We argue that higher stock price informativeness, which we measure by the probability of informed trading, helps and encourages shareholders to incentivize the top management team based on stock market performance. The regression results support our argument and show that a higher level of stock price informativeness is associated with higher CEO PPSs. Moreover, the impact of stock price informativeness on CEO incentives is stronger for privately controlled listed firms than it is for state-controlled listed firms. The results also hold when information asymmetry is approximated by the accuracy and dispersion of the earnings forecasts made by financial analysts.
