    Discussion of “The Differential Persistence of Accruals and Cash Flows for Future Operating Income versus Future Profitability”

    Fairfield et al. (2003a, this issue) suggests that the accrual effect in Sloan (1996) is at least partly due to the fact that accruals signify an increase in (less-productive) net operating assets. Thus, the paper is a useful and thought-provoking reminder that accruals have both earnings and balance sheet effects. However, the impact of the empirical results is diminished by the lack of a convincing story that ties and grounds these results to other knowledge in the area.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47736/1/11142_2004_Article_5127178.pd

    News or Noise?

    This study investigates the quality of the U.S. News annual ranking of national universities and liberal arts colleges. The main finding is that current rankings changes have a strong tendency to revert over the following two rankings. Using a simple model, this study estimates that about 70 to 80 percent of the variation in rankings changes is transitory and reversible. Thus, most of the “news” in the annual rankings is essentially meaningless noise. An analysis of possible explanations suggests that the noise in annual ranking changes is most likely due to various measurement, estimation, and other information processing errors in the rankings' underlying components.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43624/1/11162_2004_Article_297322.pd

    Default Risk and Equity Returns: A Comparison of the Bank-Based German and the U.S. Financial System

    In this paper, we address the question whether the impact of default risk on equity returns depends on the financial system firms operate in. Using an implementation of Merton's option-pricing model for the value of equity to estimate firms' default risk, we construct a factor that measures the excess return of firms with low default risk over firms with high default risk. We then compare results from asset pricing tests for the German and the U.S. stock markets. Since Germany is the prime example of a bank-based financial system, where debt is supposedly a major instrument of corporate governance, we expect that a systematic default risk effect on equity returns should be more pronounced for German rather than U.S. firms. Our evidence suggests that a higher firm default risk systematically leads to lower returns in both capital markets. This contradicts some previous results for the U.S. by Vassalou/Xing (2004), but we show that their default risk factor looses its explanatory power if one includes a default risk factor measured as a factor mimicking portfolio. It further turns out that the composition of corporate debt affects equity returns in Germany. Firms' default risk sensitivities are attenuated the more a firm depends on bank debt financing

    Introduction: Onychomycosis is a frequent nail disorder, accounting for up to 50% of all nail problems. Treatment of onychomycosis is expensive and requires a long time of antifungal medications. Consequently, a proper and faster diagnosis is necessary. Especially for those patients with diabetes mellitus, where onychomycosis is among the most significant predictors of foot ulcer and possible severe complications.Aim: To compare the sensitivity, specificity, and turnaround time between direct microscopy, culture, histology, and real-time PCR. In addition, to compare the frequency and etiology of onychomycosis in patients with and without DM.Materials and methods: This study included 102 patients, divided into two groups. One group consisted of patients with diabetes mellitus and the other – without diabetes. Nail samples were collected and examined by direct KOH microscopic examination, culture, histology, and real-time PCR.Results: From the 102 patients with clinical onychomycosis, positive KOH was found in 38 (37.3%). Culture – 82 out of 102 samples (80.4%) were positive for dermatophytes, yeasts, and/or NDM. Positive histology samples were 32 (41.6%). The PCR was positive in 57 (55.9%) out of the 102. We discovered that there is no significant statistical difference in the etiology of the fungal infections between the two groups.Conclusions: All mycological investigations have their place in the diagnosis of onychomycosis. Direct microscopy, culture, and histology are useful methods for clinicians to diagnose and follow up the post-treatment period. The advantages of RT-PCR include obtaining results faster and accurately identifying fungi, thus becoming more valued in the diagnosis of OM

    Where do firms manage earnings?

    Despite decades of research on how, why, and when companies manage earnings, there is a paucity of evidence about the geographic location of earnings management within multinational firms. In this study, we examine where companies manage earnings using a sample of 2,067 U.S. multinational firms from 1994 to 2009. We predict and find that firms with extensive foreign operations in weak rule of law countries have more foreign earnings management than companies with subsidiaries in locations where the rule of law is strong. We also find some evidence that profitable firms with extensive tax haven subsidiaries manage earnings more than other firms and that the earnings management is concentrated in foreign income. Apart from these results, we find that most earnings management takes place in domestic income, not foreign income.Arthur Andersen (Firm) (Arthur Andersen Faculty Fund

    Corporate boards and performance pricing in private debt contracts

    This paper investigates the effects of corporate governance on the use of performance pricing in debt contracts on a sample of newly syndicated loans in the U.S. private debt market. While cross-sectional results provide no evidence for the predicted relation between corporate governance quality and the likelihood of using performance pricing in debt contracts, there is evidence for the predicted positive relation between corporate governance quality and the use of interest-increasing performance pricing provisions. Evidence also provides support for the predicted negative relation between corporate governance quality and the use of financial ratio as the measure of performance underlying the provisions. Overall, empirical evidence supports the hypothesis that debt-holders perceive aspects of corporate governance to be beneficial and factor them in their contracting decisions
