The Explanatory Power of Canadian Accounting Measures of Earnings Dilution*

This paper examines the properties of the accounting measures of dilution under pre‐2001 Canadian GAAP. Fully diluted earnings per share (EPS) presents investors with a per‐share figure that attempts to capture the maximum potential dilution that would occur if all dilutive convertible securities were converted and all dilutive stock options and rights exercised. We examine how the difference between basic and fully diluted EPS, which we refer to as the dilutive adjustment, affects the ability of EPS to predict one‐period‐ahead EPS. Moreover, we address the issue of the explanatory power of changes in the dilutive adjustment for unexpected stock returns over the year and at the earnings announcement date. Surprisingly, in contrast with the traditional accounting view that increases in the dilutive adjustment present the investor with bad news due to potential dilution of the future earnings stream, the dilutive adjustment is positively related to next period's earnings and increases in the dilutive adjustment are positively correlated with contemporaneous long‐window stock returns. These results can be attributed to the relation between the dilutive adjustment and the earnings process combined with a partial resolution of the uncertainty attached to growth firms. We find no evidence that investors use information from the disclosure of fully diluted EPS at the earnings announcement date. These results are consistent with increases in the dilutive adjustment capturing the partial realization of a firm's growth potential that more than outweighs the potential dilution attached to the convertible securities; however, this information appears to be already embedded in price prior to the disclosure of fully diluted EPS.     

Undetected Deviations in Tests of Controls: Experimental Evidence of Nonsampling Risk*

The objective of the study was to examine the effects of three independent variables ‐ accountability, audit workpaper structure, and type of control deviations ‐ on auditors' detection failure rates during control tests in a purchases, payables, and payments cycle. The experimental design used a between‐subjects manipulation of accountability and workpaper structure, and a within‐subjects manipulation of deviation type. Consistent with prior research, we observed an alarmingly high detection failure rate of 42.3 percent. This failure rate was not affected by levels of accountability or workpaper structure, although postexperiment evidence suggests that these variables were successfully manipulated. Failure rates did depend on the type of seeded control deviation, with nonmonetary deviations being overlooked most frequently. In addition to replicating prior research, our study makes two further contributions. First, we provide empirical evidence that supports Hirst's (1992) speculation that successful manipulations of accountability may not affect auditor performance because auditors may self‐induce levels of accountability that create a ceiling effect on auditor performance. Second, we observe that although auditors perceived that highly structured workpapers allowed them to be more effective and efficient when performing tests of controls, their actual audit performance was not more effective and, on average, was less efficient.     

Do Your Neighbors Influence Your Health?

When individuals make decisions regarding their allocation of time and income, the health investment and health that they achieve may fall short of the goals prescribed by medical guidelines and health policymakers. Instead of the oft‐observed policy responses such as additional spending on public awareness campaigns, it may be more fruitful to determine how individuals can be induced to choose behaviors that will lead to the prescribed health. That is, one must recognize the trade‐offs between health investment and consumption or leisure today in the face of factors such as social norms, job stress and advances in health technology.     

Jump-Diffusion Processes and the Term Structure of Interest Rates

The authors investigate the term structure of interest rates when the underlying state variables and production technologies follow the jump-diffusion processes. Even in some cases where the traditional expectations theory about the term structure is consistent with general equilibrium under diffusion processes, the traditional theory is not consistent under jump-diffusion processes. It is shown that bond prices are strictly higher under jump risks than otherwise and that consumers with logarithmic utility functions will develop hedge portfolios in the presence of jump diffusion.
