Investor reactions to derivative use and outcomes

How do investors evaluate managers who choose whether or not to use derivatives once the outcomes of those decisions become known? Different theories offer different predictions, and we test these in three experiments. Results show that investors are more satisfied with firm managers and assign a higher value to firms when managers use derivatives (that address firm risks) than when they do not. This result occurs even though we hold constant the economic differences typically present when comparing derivative use versus non-use (that is, ex ante risk and ex post outcome), suggesting that investors reward firms that use derivatives. Additional tests reveal that investors believe that managers who use derivatives in these situations exhibit a higher level of decision-making care than those who do not use derivatives. We also document that these inferences about greater decision-making care do not apply to the speculative use of derivatives. Overall, our study adds to our understanding of how investors judge companies that use derivatives, given the resulting outcomes of such use.     

Characteristics and Information Value of Credit Watches

We analyze credit watch and rating actions to better understand the role of credit watches in the credit rating process. We find that watch actions are more frequently prompted by specific, publicly known events than are rating actions. The likelihood that a watch action precedes a rating action varies systematically with proxies for investor demand for credit quality information and the adverse consequences of issuing a rating change prematurely. Credit watches occur more often in response to deterioration in credit quality, and issuers make concerted efforts to address the concerns that prompted down watches. Down watches are less likely than up watches to indicate the direction of the subsequent rating change. Watch announcements are associated with abnormal stock returns, indicating that credit watch actions are significant information events. Our results suggest that credit watches are informative and facilitate the stability of ratings by allowing firms to correct deficiencies and prevent downgrades.     

Improving Ethical Attitudes or Simply Teaching Ethical Codes? The Reality of Accounting Ethics Education

ABSTRACT

Ethical instruction is critical in accounting education. However, does accounting ethics teaching actually instil core ethical values or simply catalogue how students should act when confronted with typical accounting ethical dilemmas? This study extends current literature by distinguishing between moral/ethical and legal/ethical matters and then re-evaluating the effectiveness of ethics training. A cohort of final-year accounting students with significant ethical training evaluated ethical scenarios. Half were moral (non-legal) and half contained legal as well as moral components. After further ethical instruction they re-evaluated the scenarios. Ethical attitudes towards legal/moral issues improved, but attitudes towards moral-only issues did not. This questions previous studies which purport to demonstrate the effectiveness of ethical instruction and queries the benefits of accounting ethics education. Are fundamental ethical principles being ignored in an effort to prevent more obvious accounting wrongdoings? Accounting ethics training needs to be reassessed if true ethical improvement is to be achieved.     

领先技术能挽救EDA行业吗?--商业化的半导体设计软件业未雨绸缪

也许从表面上看,EDA(电子设计自动化)领域风平浪静,但其实一些大的改变正在酝酿着.     

传统EDA公司面临冲击

将硬件设计工作“隔墙”扔给软件部门完成的日子是否要最终结束呢?如果英国牛津郡Celoxica公司提供的工具能够流行起来的话,这一天也许就将来临。到目前为止,Celoxica公司的绝大部分业务仍然来自其最大的几个客户,像半导体领域的富士通,这家公司使用Celoxica的工具进行原型芯片的设计以发现芯片的缺陷,在芯片制造之前避免进行昂贵的重新设计。     

Truth claims and explanatory claims—An ontological typology of futures studies

Classifications of futures research are usually based on epistemological differences, but we complete these with ontological considerations. The article presents a typology of forecasts, i.e. statements on future events or states. It has two dimensions, truth claim and explanatory claim; each dimension has two values, making the claim or not making the claim. The four outcomes are: forecasts which make both truth claims and explanatory claims (predictions); forecasts which make truth claims, but not explanatory claims (prognoses); forecasts which make explanatory claims, but not truth claims (science fiction); and forecasts which make neither truth claims nor explanatory claims (utopias or dystopias). We regard each outcome as an ideal type, against which forecasts can be measured. We illustrate the use of the typology by presenting an example of each outcome.     

Changes in bonus contracts in the post-Sarbanes–Oxley era

We examine whether the relation between earnings and bonuses changes after Sarbanes–Oxley. Theory predicts that, as the financial reporting system reduces the discretion allowed managers, firms will put more weight on earnings in compensation contracts to encourage effort. However, the increased risk imposed by Sarbanes–Oxley on executives may cause firms to temper this contracting outcome. We examine and find support for the joint hypothesis that the implementation of Sarbanes–Oxley and related reforms led to a decrease in earnings management and that firms responded by placing more weight on earnings in bonus contracts. We find no evidence that firms changed compensation contracts to compensate executives for assuming more risk.
