Agency Conflicts and Corporate Payout Policies: A Global Study

We investigate the roles of firm and country level agency conflicts in determining corporate payout policies. Based on a large sample of 29,610 firms in 43 countries from 2001 to 2006, we find that in high protection countries, investors are able to use their legal powers to extract cash from firms but their ability to do so can be substantially hindered when agency costs at the firm level are high. In poor protection countries, investors can seek refuge in firm level governance mechanisms to curb agency conflicts, suggesting a substitution between country and firm level investor protection. Finally, compared to repurchases, we find dividends are more likely to be the sole method of payout in high protection countries and in less closely held firms

Analysis of shared heritability in common disorders of the brain

ience, this issue p. eaap8757 Structured Abstract INTRODUCTION Brain disorders may exhibit shared symptoms and substantial epidemiological comorbidity, inciting debate about their etiologic overlap. However, detailed study of phenotypes with different ages of onset, severity, and presentation poses a considerable challenge. Recently developed heritability methods allow us to accurately measure correlation of genome-wide common variant risk between two phenotypes from pools of different individuals and assess how connected they, or at least their genetic risks, are on the genomic level. We used genome-wide association data for 265,218 patients and 784,643 control participants, as well as 17 phenotypes from a total of 1,191,588 individuals, to quantify the degree of overlap for genetic risk factors of 25 common brain disorders. RATIONALE Over the past century, the classification of brain disorders has evolved to reflect the medical and scientific communities' assessments of the presumed root causes of clinical phenomena such as behavioral change, loss of motor function, or alterations of consciousness. Directly observable phenomena (such as the presence of emboli, protein tangles, or unusual electrical activity patterns) generally define and separate neurological disorders from psychiatric disorders. Understanding the genetic underpinnings and categorical distinctions for brain disorders and related phenotypes may inform the search for their biological mechanisms. RESULTS Common variant risk for psychiatric disorders was shown to correlate significantly, especially among attention deficit hyperactivity disorder (ADHD), bipolar disorder, major depressive disorder (MDD), and schizophrenia. By contrast, neurological disorders appear more distinct from one another and from the psychiatric disorders, except for migraine, which was significantly correlated to ADHD, MDD, and Tourette syndrome. We demonstrate that, in the general population, the personality trait neuroticism is significantly correlated with almost every psychiatric disorder and migraine. We also identify significant genetic sharing between disorders and early life cognitive measures (e.g., years of education and college attainment) in the general population, demonstrating positive correlation with several psychiatric disorders (e.g., anorexia nervosa and bipolar disorder) and negative correlation with several neurological phenotypes (e.g., Alzheimer's disease and ischemic stroke), even though the latter are considered to result from specific processes that occur later in life. Extensive simulations were also performed to inform how statistical power, diagnostic misclassification, and phenotypic heterogeneity influence genetic correlations. CONCLUSION The high degree of genetic correlation among many of the psychiatric disorders adds further evidence that their current clinical boundaries do not reflect distinct underlying pathogenic processes, at least on the genetic level. This suggests a deeply interconnected nature for psychiatric disorders, in contrast to neurological disorders, and underscores the need to refine psychiatric diagnostics. Genetically informed analyses may provide important "scaffolding" to support such restructuring of psychiatric nosology, which likely requires incorporating many levels of information. By contrast, we find limited evidence for widespread common genetic risk sharing among neurological disorders or across neurological and psychiatric disorders. We show that both psychiatric and neurological disorders have robust correlations with cognitive and personality measures. Further study is needed to evaluate whether overlapping genetic contributions to psychiatric pathology may influence treatment choices. Ultimately, such developments may pave the way toward reduced heterogeneity and improved diagnosis and treatment of psychiatric disorders

The cost of being ethical: Evidence from Islamic equity funds

This paper examines the relationship between financial performance and ethical screening intensity of a special class of ethical funds that is rooted in Islamic values – Islamic equity funds (IEFs). These faith-based ethical funds screen investments on compliance with Islamic values where conventional interest expense (riba), gambling (maysir), excessive uncertainty (gharar), and non-ethical (non-halal) products are prohibited. We test whether these extra screens affect the financial performance of IEFs relative to non-Islamic funds. Based on a large survivorship-free international sample of 387 Islamic funds, our results show that IEFs on average underperform conventional funds by 40 basis points per month, or 4.8% per year (supporting the underperformance hypothesis). While Islamic funds do not generally perform better during crisis periods, they outperformed conventional funds during the recent sub-prime crisis (supporting the outperformance hypothesis). Using holdings-based measures for ethical screening intensity, results show IEFs that apply more intensive screening perform worse, suggesting that there is a cost to being ethical

The pricing of underwriting services in the Australian capital market

Recent media releases have placed enormous strains on the credibility of the underwriting industry. It has been alleged that underwriters in the US and UK collude and fix underwriting fees. In contrast to recent evidence on underwriter spreads in the US (Chen, H.-C., Ritter, J.R., 2000. The seven percent solution. Journal of Finance, in press.), we find that Australian underwriting fees are not clustered at one particular percentage. Using 282 underwritten industrial IPOs from 1980 to 1996, we find that underwriters systematically price their services according to firm-specific variables such as the offer size, the subscription period of the issue, the retained ownership after the IPO, the offer price, and whether options form part of the underwriter's compensation.</p

The Impact of Forecast Disclosure and Accuracy on Equity Pricing:The IPO Perspective

In a relatively less litigious environment like Australia, it is common to find IPO firms that voluntarily provide forecasts in their prospectus. Using 158 Australian industrial IPOs listed from 1991 to 1997, we examine the impact of the disclosure and accuracy of earnings and dividend forecasts on equity pricing. Our results show that IPO firms’ disclosure policy is not related to their initial and long-run valuation. However, the market appears to price managers’ ability to forecast: firms with inaccurate earnings and dividend forecasts, especially those that fall short of their forecasts, experience adverse price reactions surrounding the day when the actual figures are released. Our results also show a significant relationship between forecast errors and IPO firms’ postlisting performance. Further analysis shows that this relationship is driven mainly by the announcement effect.</p
