Tax complexities relating to corporate tax losses, induced by debt finance, and to the differential tax treatment of equity and sterling debt, are introduced into corporate valuation. The after personal tax value of the geared firm can be less than that of the equivalent ungeared firm. Also, debt-induced tax losses can create negative betas. These fiscal effects are incorporated into degearing formulae under active and passive debt management policies.  相似文献

Within the context of the study, a firm is said to have an advantageover another if it obtains more customers given they both chargethe same price. Further, consumer switching costs imply thelarger the difference in the prices charged by the two firmsthe greater the proportion of consumers who switch from thehigher-priced firm to the lower-priced one. The Nash equilibriumto the price-posting game is characterized The firm with theadvantage charges a higher price Finally, it is shown that ifone firm can freely choose to have an advantage, it will rejectit. This follows as the greater the advantage, the smaller theequilibrium profits to both firms.  相似文献

This paper uses the generalised extreme value (GEV) distribution to model the extreme losses that are likely to occur during market crashes, in the case of an investor who has long positions in stocks and currencies. The null hypothesis – which tests for normality of asset returns – is rejected due to asymmetry of these returns. We assume that the asymmetric behaviour and volatility of the returns are captured by the shape and scale parameters, respectively, of a GEV distribution. The data set includes stock indices for the United States, Japan, the United Kingdom, Germany, France and South Africa, and the South African rand exchange rates against the US dollar observed from 3 January 2005 to 30 December 2009. In addition, we divide this sample period into two periods: the pre‐crisis period, from 3 January 2005 to 31 December 2007 and the crisis period, from 1 January 2008 to 30 December 2009. We compared the estimates of value at risk (VaR) using an extreme value theory (EVT) model, with the estimates derived from the traditional variance–covariance method and found that during the crisis the 99% extreme VaR estimates are more reliable as they lie within the Basel II green zone. These results suggest that, at higher quintiles, the VaR estimates based on EVT are reliable and more accurate than estimates from the traditional method.  相似文献

This analysis of consumer affairs professionals in business and government describes what functions they perform, where they are employed, what education and experience is required and what their salaries are. Professional educators in the consumer field have generally ignored the career field of consumer affairs professional. Colleges and universities train consumer majors to be educators, researchers, or extension workers, but little attention is paid to the education of consumer affairs professionals for business and government. This article not only attempts to give educators in the consumer field a greater awareness of this relatively new career so that they can develop educational programs more intelligently but also attempts to make business and government more aware of what is being done in this area so they may be able to utilize the talents of consumer affairs professionals.  相似文献
