SIX CHALLENGES IN DESIGNING EQUITY-BASED PAY

The past two decades have seen a dramatic increase in the equitybased pay of U.S. corporate executives, an increase that has been driven almost entirely by the explosion of stock option grants. When properly designed, equity‐based pay can raise corporate productivity and shareholder value by helping companies attract, motivate, and retain talented managers. But there are good reasons to question whether the current forms of U.S. equity pay are optimal. In many cases, substantial stock and option payoffs to top executives–particularly those who cashed out much of their holdings near the top of the market–appear to have come at the expense of their shareholders, generating considerable skepticism about not just executive pay practices, but the overall quality of U.S. corporate governance. At the same time, many companies that have experienced sharp stock price declines are now struggling with the problem of retaining employees holding lots of deep‐underwater options. This article discusses the design of equity‐based pay plans that aim to motivate sustainable, or long‐run, value creation. As a first step, the author recommends the use of longer vesting periods and other requirements on executive stock and option holdings, both to limit managers' ability to “time” the market and to reduce their incentives to take shortsighted actions that increase near‐term earnings at the expense of longer‐term cash flow. Besides requiring “more permanent” holdings, the author also proposes a change in how stock options are issued. In place of popular “fixed value” plans that adjust the number of options awarded each year to reflect changes in the share price (and that effectively reward management for poor performance by granting more options when the price falls, and fewer when it rises), the author recommends the use of “fixed number” plans that avoid this unintended distortion of incentives. As the author also notes, there is considerable confusion about the real economic cost of options relative to stock. Part of the confusion stems, of course, from current GAAP accounting, which allows companies to report the issuance of at‐the‐money options as costless and so creates a bias against stock and other forms of compensation. But, coming on top of the “opportunity cost” of executive stock options to the company's shareholders, there is another, potentially significant cost of options (and, to a lesser extent, stock) that arises from the propensity of executives and employees to place a lower value on company stock and options than well‐diversified outside investors. The author's conclusion is that grants of (slow‐vesting) stock are likely to have at least three significant advantages over employee stock options:

• ? they are more highly valued by executives and employees (per dollar of cost to shareholders);
• ? they continue to provide reasonably strong ownership incentives and retention power, regardless of whether the stock price rises or falls, because they don't go underwater; and
• ? the value of such grants is much more transparent to stockholders, employees, and the press.

     

Costs of broad-based stock option plans

We generate estimates of the costs of broad-based stock option programs under varying assumptions about why firms use these pay schemes. We show that, if accounting considerations alone drive option grants, a typical firm in our sample incurs between 50 cents and one dollar of real costs in order to increase reported pre-tax net income by one dollar. This cost is reduced, but is still quite substantial, if accounting leads firms to grant options rather than restricted stock. We also show that, if option grants are efficient, the patterns in our data are consistent with firms using these grants to attract and retain employees.     

Zero leverage puzzle: Do labour laws matter?

Exploiting the staggered passage of labour protection laws in the United States, we find that higher labour adjustment costs increased the likelihood of observing zero leverage firms by 22%. This effect is significantly larger in states with stronger unionization, in industries with higher volatility and concentration, and in firms with higher labour intensity. Both within-firm changes in debt policies and higher propensity of newer firms to be debt-free are important in explaining these patterns. Overall, our work contributes to the literature on the relation between financial and labour markets by highlighting the role of labour laws in explaining the zero-leverage puzzle.     

An empirical analysis of continuing improvements following the implementation of a performance-based compensation plan

Performance improvements subsequent to the implementation of a pay-for-performance plan can result because more productive employees self-select into the firm (selection effect) and because employees allocate effort to become more effective (effort effect). We analyze individual performance data for 3,776 sales employees of a retail firm to evaluate these alternative sources of continuing performance improvement. The incentive plan helps the firm attract and retain more productive sales employees, and motivates these employees to further improve their productivity. In contrast, the less productive sales employees’ performance declines before they leave the firm.     

Incentives,wages, and promotions: theory and evidence

I study an incentive problem that has been largely ignored in the agency literature: incentives for repeated (human capital) investment. The optimal contract is very simple but still provides rich implications for incentive and wage structures in large organizations. The empirical evidence is presented using personnel records of health insurance claim processors in a large U.S. insurance company. These processors are white‐collar, nonmanagerial, female, service industry workers—a rapidly growing but rarely studied labor group. The empirical findings are consistent with the main features of the optimal contract.     

Equity‐based incentives and shareholder say‐on‐pay

We study the relationship between CEO pay‐performance sensitivity, pay‐risk sensitivity, and shareholder voting outcomes as part of the “say‐on‐pay” provision of the 2010 US Dodd‐Frank Act. Consistent with our hypothesis, we provide evidence that shareholders tend to approve of compensation packages that are more sensitive to changes in stock price (pay‐performance sensitivity). Our findings are consistent with theoretical predictions that outside owners approve of equity incentives as a means of aligning managers' interests with those of shareholders. We also document that future changes to equity‐based incentives are related to voting outcomes and that shareholders incorporate CFO incentives into their votes. Collectively, these results provide evidence of the importance of equity‐based incentives from the perspective of those most concerned with firm value and of the effectiveness of say‐on‐pay as a governance mechanism.     

The effect of unionization on firms’ earnings management and employee compensation: Evidence from a regression discontinuity design

This study examines the effect of unionization on US firms’ accruals-based earnings management and future employee compensation expenses by employing a research design that overcomes the inherent endogeneity issue of the relationship between unionization and earnings management. First, by comparing firms that just pass unionization by a small number of votes to those that just barely lose elections, the regression discontinuity design estimations document significant downward accruals earnings management for firms that barely pass unionization, compared to those that barely fail to pass unionization. Second, the association between unionization and earnings management is only significant in US states without right-to-work legislation, where unions are more powerful. These findings are consistent with recently unionized firms’ incentives to report lower earnings in order to mitigate unions’ demands for greater employee compensation. Further, for firms that barely pass unionization, we find that: (1) unions cannot fully “undo” the effects of earnings management, that is, downward managed earnings depress future compensation expenses, and (2) firms cannot fully “undo” the effects of unionization, that is, compensation expenses increase after unionization despite the downward earnings management.     

Three Versions of Perfect Pay for Performance (Or The Rebirth of Partnership Concepts in Executive Pay)

During the 19th century and the first half of the 20th, the compensation of non‐founder managers of U.S. public companies was guided by partnership concepts. Andrew Carnegie made his senior staff coowners by selling them stock at book value. And Alfred Sloan gave the senior staff of General Motors a fixed percentage of the company's “economic profit.” But in the years since World War II, such partnership concepts have largely disappeared from executive pay. The current view of executive pay is guided by the concepts of “competitive pay” and pay components. But unlike the partnership models of the past, today's “human resources model” of executive pay fails to provide useful guidance to companies on how to achieve a consistent relationship between pay and corporate performance, as reflected in returns to shareholders. As the author argues, the model's insistence on providing “competitive pay” packages that are (1) based on size (that is, on revenue not profitability) and (2) “recalibrated” every year regardless of past performance has the effect of undermining management's incentives by rewarding poor past value performance with increases (instead of reductions) in sharing percentage, and penalizing superior value performance with reductions (instead of increases) in sharing percentage. In recent years, however, three different model pay plans have been proposed that provide both competitive pay and fixed pay leverage in relation to shareholder value. The author is the source of one of the three “perfect” pay plans. The other two are (1) the Dynamic Incentive Account proposed by Alex Edmans of London Business School and Xavier Gabaix of NYU and (2) the investment manager fee structure developed and used by Don Raymond, the chief investment strategist of the Canada Pension Plan. The author shows that cumulative pay under all three plans can be expressed as a function of cumulative market compensation (that is, the pay earned by one's peers over the life of the plan, thus reflecting pay levels for average performance) and cumulative value added (as reflected, say, in the company's TSR relative to the average of its peers' over the life of the plan)—and in the case of plans with equity‐like leverage, cumulative pay is the simple sum of cumulative market compensation and a fixed share of the cumulative value added. The plans reconcile retention and performance objectives more effectively than current practice because they provide competitive pay only for average performance, while using the partnership concept of fixed sharing of the value added to provide strong incentives.     

The Effectiveness of White‐Collar Crime Enforcement: Evidence from the War on Terror

This paper analyzes the impact of changes in regulatory priorities and resource allocation on criminal enforcement of white‐collar criminal activities. Using the 9/11 terrorist attacks as a shock to the FBI's priorities and allocation of investigative resources, as well as variation in the Muslim population in the United States, I examine whether prioritization of counterterrorism investigations after 9/11 is associated with weaker enforcement of laws targeting white‐collar crime. I then use a difference‐in‐differences estimation to study the magnitude of any increase in white‐collar crime resulting from reduced oversight. I find a significantly greater reduction in white‐collar criminal cases referred by FBI field offices that shifted more of their investigative focus away from white‐collar crime to counterterrorism. Further, geographic areas in the jurisdictions of FBI field offices with greater shifts in attention from white‐collar crime to counterterrorism experienced greater increases in wire fraud, illegal insider‐trading activities, and fraud within financial institutions.

本文考察薪酬差距如何影响企业内部的人力资本结构变动。基于员工不同教育程度划分人力资本层次,本文研究发现:(1)薪酬差距的增加显著降低了大学学历员工的比例,同时提升了高中及以下学历员工的比例;(2)通过构造工具变量和基于全球性经济危机的场景设定,我们发现薪酬差距和人力资本结构之间存在显著的因果关系;(3)在薪酬差距水平较高的情况下,薪酬差距的增加显著吸引了更有可能进入企业中高层的高学历员工。在薪酬差距水平较低的情况下,扩大薪酬差距显著提升(降低)了高中及以下学历(大学学历)员工比例,一个可能原因在于不同学历员工的议价能力存在差异。(4)薪酬差距与人力资本结构变化之间的相关性主要体现在规模较大、管理者平均年龄较低的企业。(5)人力资本结构在薪酬差距影响创新的过程中发挥了显著的中介效应,薪酬差距提升了研究生和本科学历员工比例,促进了企业创新。     

Medical Labour Supply and the Production of Healthcare

Medical labour markets are important because of their size and the importance of medical labour in the production of healthcare and in subsequent patient outcomes. We present a summary of important trends in the UK medical labour market, and we review the latest research on factors that determine medical labour supply and the impact of labour on patient outcomes. The topics examined include: the responsiveness of labour supply to changes in wages, regulation and other incentives; factors that determine the wide variation in physician practice and style; and the effect of teams and management quality on patient outcomes. This literature reveals that while labour supply is relatively unresponsive to changes in wages, medical personnel do react strongly to other incentives, even in the short run. This is likely to have consequences for the quality of care provided to patients. We set out a series of unanswered questions in the UK setting, including: the importance of non‐financial incentives in recruiting and retaining medical staff; how individuals can be incentivised to work in particular specialties and regions; and how medical teams can be best organised to improve care.     

The real effects of financial reporting on pay and incentives

This paper discusses two real effects of financial reporting on pay and incentives: (1) Better earnings leads to better incentives, and (2) If pay is mismeasured, pay can be misused. The first real effect follows from the fact that incentives are often based on earnings, and the effectiveness of earnings-based incentives is positively related to the quality of earnings. Greater use of earnings in incentives provides better incentives at a lower cost. The second real effect has to do with how well the accounting system measures the expense of various pay components. Complex calculations are required to value complex pay components such as options, post-employment benefits, and performance-vested equity, and these calculations have historically not been done correctly. The incorrect accounting leads to these pay components being misused. I conclude by discussing how accounting and disclosure of pay and incentives can be improved.     

Limiting the ACA's Threats to Small Group Health Insurance Markets

We identify three threats to small group health insurance markets that may result from the 2014 implementation of certain provisions in the Affordable Care Act (ACA). First, small employers with predominantly low‐income employees may tend to opt out of small group markets because their employees will be better off with subsidized individual coverage. Second, small employers with employees of heterogeneous income levels will have strong incentives to offer coverage that is either “unaffordable” or fails to provide “minimum value” in order to preserve the availability of government subsidies for their low‐income employees. Finally, small employers that continue to offer group plans will face increased incentives to self‐insure those plans, further contracting small group markets and subjecting them to adverse selection. Collectively, these forces may destabilize small group markets and increase the ACA's fiscal cost. We therefore conclude by offering various reforms aimed at offsetting these risks and preserving the viability of small group markets.     

Employment Quota System and Labour Market Outcomes of Individuals with Disabilities: Empirical Evidence from South Korea

To date, only a few studies have attempted to evaluate the effectiveness of disability employment quota systems using structural changes in policies. This study exploits the structural changes in South Korea's disability employment quota system that took place in 2004 and 2006 to expand the current disability policy evaluation literature. We separate the effect of these changes in the quota system into their effect on the probability of labour force participation and their effect on the probability of employment (after controlling for selection into the labour market). We also study the extent to which the changes – which included increasing the number of employers covered by the quota system, the number of jobs available to individuals with disabilities and the financial incentives for employing individuals with disabilities – have affected job satisfaction among individuals with disabilities. Our results suggest that the changes in the quota system may have increased labour force participation but have had a limited positive impact on the probability of employment among people with disabilities in South Korea. Further, compulsory hiring and expanded opportunities have not substantially affected the level of job satisfaction observed among employees with disabilities relative to their non‐disabled counterparts.     

The Relation Between Insider-Trading Restrictions and Executive Compensation

In this study I investigate the relation between firm‐level insider‐trading restrictions and executive compensation. Using a trading‐window proxy for the existence of such restrictions, I test predictions that insiders will demand compensation for these restrictions and that firms will need to increase incentives to restricted insiders. I find that firms that restrict insider trading pay a premium in total compensation relative to firms not restricting insider trading, after controlling for economic determinants of pay. Furthermore, these firms use more incentive‐based compensation and their insiders hold larger equity incentives relative to firms that do not restrict insider trading. These results hold after controlling for the endogenous decision to restrict insiders and are consistent with the notion that insider trading plays a role in rewarding and motivating executives.     

The Labour Market Impact of the Working Families' Tax Credit

In October 1999, the working families' tax credit (WFTC) replaced family credit as the main package of in‐work support for families with children. Among a range of stated aims, the WFTC is intended to‘… improve work incentives, encouraging people without work to move into employment'. In this paper, we consider the impact of WFTC on hours and participation. To simulate labour supply responses, we use a discrete behavioural model of household labour supply with controls for fixed and childcare costs, and unobserved heterogeneity. In simulation, we experiment with a number of scenarios regarding the take‐up of the credit, entry wage level and hourly childcare price. We find participation rates among single mothers to increase by around 2.2 percentage points for the base‐case scenario, while for married women participation rates are modelled to fall. Our simulation results indicate a small increase in overall participation of around 30,000 individuals.     

Rank and file equity compensation and earnings management: Evidence from stock options

The widespread use of rank and file equity‐based compensation suggests that executives believe that rank and file employees can affect firm outcomes, and some research supports this view. If equity‐based incentives influence rank and file employees’ productive efforts, they might also influence their earnings management decisions. We find that increases in rank and file employees’ option‐based compensation—our proxy for equity‐based compensation—are associated with increases in earnings management and that this relation is attributable to real activities (as opposed to accrual) earnings management. Cross‐sectional tests indicate that the relation is stronger when rank and file option compensation is likely to generate greater performance incentives and attenuated in the presence of more intense monitoring. Finally, we explore the role of cash constraints and overvaluation as potential alternative explanations for this relation and find that neither accounts for our results.     

Do Firms Use Time‐Vested Stock‐Based Pay to Keep Research and Development Investments Secret?

I find that executives’ unvested equity holdings are larger when executives are employed by R&D‐intensive firms in industries that rely more on secrecy to profit from R&D. Moreover, I find that this relation is more pronounced for executives with a greater ability to exploit R&D‐related information and also holds for nonexecutive employees. In addition, I find that these firms use option grants with longer vesting periods and that unvested equity holdings reduce the likelihood that their executives leave to find employment elsewhere. Overall, my findings are consistent with firms using time‐vested stock‐based pay to reduce the leakage of R&D‐related information to competitors through employee mobility.     

Do Entrenched Managers Pay Their Workers More?

Analyzing a panel that matches public firms with worker-level data, we find that managerial entrenchment affects workers' pay. CEOs with more control pay their workers more, but financial incentives through cash flow rights ownership mitigate such behavior. Entrenched CEOs pay more to employees closer to them in the corporate hierarchy, geographically closer to the headquarters, and associated with conflict-inclined unions. The evidence is consistent with entrenched CEOs paying more to enjoy private benefits such as lower effort wage bargaining and improved social relations with employees. Our results show that managerial ownership and corporate governance can play an important role for employee compensation.     

Understanding merger incentives and outcomes in the US mutual fund industry

This paper examines the incentives of acquirers and targets in the merger market. Using data on acquisitions among mutual fund management companies from 1991 to 2004, I estimate a two-sided matching model of the merger market jointly with equations representing merger outcomes. According to the empirical investigation, although the desire to achieve a sufficient scale to attract investors is a key driver for mergers, some mergers seem to be driven by objectives other than shareholder value maximization. I find that companies that are potentially prone to misaligned incentives between owners and managers are more acquisitive than others, yet have significantly worse post-merger operating performance. I also find that these acquirers, despite their higher willingness to pay for targets, are not any more likely to match with high-quality targets, potentially due to targets’ incentive to avoid bad organizations.
