This study examines the influence of day-of-the-week patterns in security returns on long-run IPO underperformance. Comparisons are made between the IPOs in Ritter's [20] database, and a constructed set of matching firms based on SIC code and size, using NYSE, AMEX, and NASDAQ securities. It is found that virtually all of the IPO underperformance occurs on Mondays and Tuesdays and that the degree of underperformance significantly differs from other days. Thus, a common explanation may exist for the general day-of-the-week pattern in security returns and IPO long-run underperformance. 相似文献

Railtrack plc, floated in 1996, was the private sector owner of Britain's railway track, signals and stations. Its major source of revenue came from track access charges, which individual train operating companies (TOCs) paid for use of the infrastructure. Since many of these TOCs received substantial subsidies to assist in paying their track access charges, Railtrack was in effect being heavily subsidised. In October 2001, the Government decided that these arrangements were no longer viable and placed Railtrack into administration. This article explains how the level of indirect subsidies to Railtrack had become excessive, and raises crucial questions that need to be addressed in settling the future shape of the railway industry. 相似文献

I examine the effect of employee equity‐based compensation (EBC) on firm performance and the determinants of EBC. Using two samples, I find that firms have come to rely more heavily on EBC than in the past. For both samples, I document a significant, positive relation between Tobin's q and the percentage of employee compensation that is equity based. For accounting returns, I find a positive relation with the earlier sample. However, for the later sample I find that greater use of EBC leads to lower levels of future accounting returns. I also find that the determinants of the proportion of EBC are different between the two samples. 相似文献

In 1983, the Greater London Council adopted a policy of 'Contract Compliance' designed to ensure that firms selling goods and services to the Council complied with its equal opportunity requirements. The initiative aroused wide interest and many other local authorities - 40 are known of to date - have been considering introducing such a policy. Although simple in essence, its execution can be complex and difficult. In April 1986, the Inner London Education Authority, a partner in the GLC policy, took over the Contract Compliance Unit following the GLCs abolition. Linda Smith explains the background to contract compliance, how the GLC, now ILEA, operates the policy; assesses its achievements and its significance and explores some of the lessons learnt in its three years of operation. 相似文献

The Stability Pact ‐ intended to make EMU governments run prudent budgets ‐ is losing its credibility. This article asks the question: what will happen if national debts start to rise again and some governments then have difficulty borrowing? It suggests that there will be calls for bailout, that the EU's political structures will not cope well with the resulting arguments over which countries will pay, and that the eventual and painful result will be a return to the principle that currencies and political areas coincide. 相似文献

The price movements of certain assets can be modeled by stochastic processes that combine continuous diffusion with discrete jumps. This paper compares values of options on assets with no jumps, jumps of fixed size, and jumps drawn from a lognormal distribution. It is shown that not only the magnitude but also the direction of the mispricing of the Black-Scholes model relative to jump models can vary with the distribution family of the jump component. This paper also discusses a methodology for the numerical valuation, via a backward induction algorithm, of American options on a jump-diffusion asset whose early exercise may be profitable. These cannot, in general, be accurately priced using analytic models. The procedure has the further advantage of being easily adaptable to nonanalytic, empirical distributions of period returns and to nonstationarity in the underlying diffusion process. 相似文献
