Why Do Pro Forma and Street Earnings Not Reflect Changes in GAAP? Evidence from SFAS 123R
This study examines how key market participants—managers and analysts—responded to SFAS 123R's controversial requirement that firms recognize stock-based compensation expense. Despite mandated recognition of the expense, some firms' managers exclude it from pro forma earnings and some firms' analysts exclude it from Street earnings. We find evidence consistent with managers opportunistically excluding the expense to increase earnings, smooth earnings, and meet earnings benchmarks but no evidence that these exclusions result in an earnings measure that better predicts future firm performance. In contrast, we find that analysts exclude the expense from earnings forecasts when exclusion increases earnings' predictive ability for future performance and that opportunism generally does not explain exclusion by analysts incremental to exclusion by managers. Thus our findings indicate that opportunism is the primary explanation for exclusion of the expense from pro forma earnings and predictive ability is the primary explanation for exclusion from Street earnings. Our findings suggest the controversy surrounding the recognition of stock-based compensation expense may be attributable to cross-sectional variation in the relevance of the expense for equity valuation, as well as to differing incentives of market participants.
Rating the Ratings: How Good are Commercial Governance Ratings?
Proxy advisory and corporate governance rating firms (such as RiskMetrics/Institutional Shareholder Services, GovernanceMetrics International, and The Corporate Library) play an increasingly important role in U.S. public markets. They rank the quality of firm corporate governance, advise shareholders how to vote, and sometimes press for governance changes. We examine whether commercially available corporate governance rankings provide useful information for shareholders. Our results suggest that they do not. Commercial ratings do not predict governance-related outcomes with the precision or strength necessary to support the bold claims made by most of these firms. Moreover, we find little or no relation between the governance ratings provided by RiskMetrics with either their voting recommendations or the actual votes by shareholders on proxy proposals.

Correcting for Cross-Sectional and Time-Series Dependence in Accounting Research
We review and evaluate the methods commonly used in the accounting literature to correct for cross-sectional and time-series dependence. While much of the accounting literature studies settings in which variables are cross-sectionally and serially correlated, we find that the extant methods are not robust to both forms of dependence. Contrary to claims in the literature, we find that the Z2 statistic and Newey-West corrected Fama-MacBeth standard errors do not correct for both cross-sectional and time-series dependence. We show that extant methods produce misspecified test statistics in common accounting research settings, and that correcting for both forms of dependence substantially alters inferences reported in the literature. Specifically, several findings in the implied cost of equity capital literature, the cost of debt literature, and the conservatism literature appear not to be robust to the use of well-specified test statistics.

Capital Budgeting: The Role of Cost Allocations
A common issue for firms is how to allocate capital resources to various investment alternatives. An extensive and long-standing literature in finance has examined various aspects of capital budgeting, including capital constraints, the determination of discount rates, and alternative approaches to estimating cash flows and handling risk, such as real options techniques. It is generally accepted that preferences of these managers may not coincide with those of the firm's owners (the principal). Consequences of asymmetric information include strategic reporting by better-informed managers (for example, "sandbagging" or "creative optimism") and a need to measure performance ex post. There has been significant progress in recent years in understanding the role of intertemporal cost charges, specifically depreciation and capital charges, in the capital budgeting process. Cost allocations across time periods and business units are essential in creating time-consistent performance measures that compare initial reports to subsequently realized outcomes. But major challenges remain in making the existing models more complete on several fronts, including (i) richer settings of capacity investments and subsequent capacity utilization, (ii) projects with sequential decisions stages and (iii) the coordination of risk exposures across the divisions of a firm. This paper reviews extant research and suggests avenues for further research.

The Efficacy of Shareholder Voting: Evidence from Equity Compensation Plans
This study examines the effects of shareholder support for equity compensation plans on subsequent chief executive officer (CEO) compensation. Using cross-sectional regression, instrumental variable, and regression discontinuity research designs, we find little evidence that either lower shareholder voting support for, or outright rejection of, proposed equity compensation plans leads to decreases in the level or composition of future CEO incentive-compensation. We also find that in cases where the equity compensation plan is rejected by shareholders, firms are more likely to propose and shareholders are more likely to approve a plan the following year. Collectively, our results suggest that shareholder votes have little impact on firms' compensation policies and that recent regulatory efforts aimed at strengthening shareholder voting rights, particularly in the context of executive compensation, may have limited effect on firms' compensation policies.
