We review recent policy initiatives in Australia, such as corporate governance reporting requirements and innovations in defining directors' roles and responsibilities, and argue that such initiatives are often premised on overly simplistic models of the role played by directors. The role and effectiveness of directors vary according to the economic activity of the firm; hence, uniform guidelines for board composition, for example, are unlikely to be economically desirable. Likewise, statutory definitions of directors' duties are unlikely to be effective unless they allow for directors' roles to vary according to circumstance. Conversely, broad legal definitions will be problematic because of uncertainties in judicial interpretation.  相似文献

We test the Elton and Gruber model of ex-dividend stock pricing over a period spanning all US tax law changes since 1926. Our results indicate that price drop ratios (ΔP/D) and ex-day returns are related to dividend and capital gains tax rates in the theorized manner. Consistent with tax clienteles, we also find that ex-day price movements of higher dividend yield stocks are driven more by corporate tax rates, while lower yield stocks are more influenced by personal rates. Finally, we demonstrate that the positive relationship between ΔP/D and the dividend yield becomes stronger as the tax differential | td− tcg | widens.  相似文献

We review the development of accounting requirements for executive stock options (ESOs) and find that the standard-setting process has been susceptible to pressure groups including the corporate sector, politicians and even the accounting profession itself. The failure of Australian and overseas accounting regulators to take tough decisions may have created a systematic bias towards the use of ESOs which can result in grossly inefficient compensation structures motivated by a desire to maximise reported profits rather than to create optimal managerial incentives. We conclude that most of the arguments against recognition of stock option expense can be dismissed as blatant self-interest at worst, or remarkably muddled thinking at best.  相似文献

Integrating Layer of Protection Analysis (LOPA) with Hazard and Operability Analysis (HAZOP) has many advantages over performing these studies separately. The merits include: fewer actions from the combined effort compared to performing only a HAZOP; team continuity resulting from the combined effort as opposed to two separate teams having possibly differing points of view; and, ultimately, a time and cost savings realized by the combination. This integration defines the risk associated with a given scenario, enabling better decisions that impact business assurance. By using the Center for Chemical Process Safety guidelines to define the independent protection layers upfront, the gray areas can often be reduced or eliminated; thereby enabling a more thorough LOPA. Examples include taking credit if a unit has two independent operators (outside and inside) responding to critical alarms, or taking credit for centralized control rooms that may allow immediate operator interaction and response. This article shows how the guidelines have been used successfully in joint HAZOP/LOPA studies, and describes an initial preparation protocol that can ensure high-quality results. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009  相似文献

The Economic Value of Volatility Timing   总被引:9,自引:0,他引:9  
Numerous studies report that standard volatility models have low explanatory power, leading some researchers to question whether these models have economic value. We examine this question by using conditional mean-variance analysis to assess the value of volatility timing to short-horizon investors. We find that the volatility timing strategies outperform the unconditionally efficient static portfolios that have the same target expected return and volatility. This finding is robust to estimation risk and transaction costs.  相似文献

We find that initial returns were more favorable for Internet initial public offerings (IPOs) than non–Internet firm IPOs. Since the demise of the Internet sector, the underpricing of Internet–firm IPOs is not significantly different from other IPOs.
Initial returns of Internet firms are positively and significantly related to underwriter prestige and to pre–IPO market conditions. However, initial returns after the demise of the Internet sector are not significantly related to these characteristics.
The aftermarket performance of Internet firms is initially favorable but weakens over time. Firms that experienced higher initial returns during the strong Internet cycle experience weaker aftermarket performance.  相似文献

Living next to godliness: Residential property values and churches   总被引:1,自引:0,他引:1  
This article extends the analysis concerning the impact of neighborhood churches on residential property values by investigating nearly 5,000 residential property transactions in Henderson, Nevada, between January 1986 and December 1990. We find that real property values decrease, at a decreasing rate, as distance from a neighborhood church increases. This result is the opposite of that reported by Do, Wilbur, and Short in a previous edition of this journal. We bolster our findings by showing that distance from the site of a future church has little or no impact on residential property values, whereas distance from an existing church is associated with lower property values. Our evidence indicates that neighborhood churches are amenities that enhance the value of neighborhood residential property. Finally, we demonstrate that larger churches (as measured by square foot of lot size) tend to have a greaterpositive impact on residential property values.  相似文献

A split bond rating occurs when Moody's and Standard & Poor give different ratings to the same issue. We examine 1,277 public industrial bond issues, where 221 have split ratings, issued from 1980 through mid-1993. For split-rated industrial bonds, neither rating agency consistently gives higher ratings. Earlier studies find yields for split-rated bonds to be priced as either the higher or the lower of the ratings. We find the yields on split-rated bonds to be an average of the yields on the two ratings. Split ratings for industrial bonds appear to reflect random differences on the part of rating agencies. Our results differ from previous studies because we use a substantially larger sample and include high-yield bonds. As long as a bond has an investment-grade rating, the underwriter fees are found to be essentially the same for all rating categories. Below investment grade, the rating substantially affects the underwriter fee. Thus, split ratings for high-yield bonds have an important effect on the underwriter spread.  相似文献

Projects of Organisation Learning (OL) are designed to facilitate a change in an organisation's ability to engage or construct their futures. However, OL remains difficult to explain and operationalise. Traditional views of Organisational Learning, by relying on implicit views of individual learning, distort the importance of the social/cultural context of learning. A Communities of Practice perspective is used to focus on locally negotiated and situated meanings in the context of the practice of valued work. A narrative approach is employed to access the values of a group of advisers required to learn and change according to the requirements of a central government department. The findings show a pattern of values not entirely disconnected from the requirements for change. However, by relying on the assumption of the diffusion of change, a change agent was unable to gain the acceptance of advisers to the requirements. It is suggested that future thinking about OL and change need to examine how talk is used to make new realities with others.  相似文献
