David Yermack 《Financial Markets and Portfolio Management》2006,20(1):33-47
This essay surveys research about the value of individual members of boards of directors. When directors join or exit corporate
boards, company stock prices respond, often in magnitudes of 1% of firm value or more. Related research shows that when a
significant event impacts the stock price of one company, the effects are transmitted to other companies that share board
members in common with the primary company. Share price reactions are sensitive to variables such as a director’s occupation,
independence, and professional qualifications. Together, this evidence suggests that a well-functioning market for directors
might already exist, making direct regulation unnecessary and possibly counter-productive. 相似文献

印花税下调在短期内对大盘股指产生显著影响,但这种影响随时间的推移而逐渐减弱;税率下调对沪市和深市单只股票具有冲击效应,个股产生正的超额收益;税率下调对两市的大盘波动性产生显著影响,刺激了"噪声交易者",在短期内产生了噪声效应。目前印花税仍然存在一些不足,建议:拓宽税基,改双向征税为单向征税,尽快开征股票交易税。 相似文献

George J. Staubus 《Abacus》2004,40(3):265-279
The two views to be addressed here are the Chambers/Sydney view that accepts only one measurement method—current net realizable price—and the Staubus/mainstream view that accepts several measurement methods in the same financial report. These two views became well-established in the literature of accounting in the 1960s and their proponents have clung tenaciously to their oft-criticized positions for some forty years. However commendable their original expositions may have been, their continuing existence does no credit to the small coterie of accountants now interested in theory.
This article is aimed at 'narrowing the areas of difference' between adherents to the two views by isolating fundamental bases for them and exposing the reasoning supporting their structures. In a nutshell, they differ in their objectives and they can be expected to survive unless their adherents agree on the objectives of financial reporting. 相似文献

关于输配电价几个重要问题的探讨 总被引:1,自引:1,他引:1
我国电力企业将要由传统的垂直垄断的模式转变为网厂分开、竞价上网的模式。电网公司作为一个独立的经营实体分离开来,有着独立的收益需求。在市场运营过程中,通过输配电价取得收益就成了电网公司取得收益的主要手段。在输配电价的制订过程之中,管制方式、输配电成本、输电定价方法、价格水平及电网投资、输配电价价区、电网提供的辅助服务等六个问题十分重要。文中就这六个问题的解决作了一些有价值的探讨。 相似文献

Using a high-frequency data set of the spot Australian/US dollar, this study examines the distribution of quotes, spreads, and returns across the trading day. By identifying the direction of trade and the subsequent quote returns from contributing banks, the segmented nature of the market into market-makers and informed and uninformed traders is investigated. The results suggest that the economic gain possible from private information is maximised over 2 to 5 quotes and is rapidly eroded by 20 quotes (about 2 min later during busy trading times) as other new information enters the market. Also, the analysis is revealing of discontinuities in trading and the volatility of pricing across the trading day. 相似文献

Previous studies have investigated the determinants of housing price cycles in the housing market; however, we observed the phenomenon of housing price jumps in the 2007 subprime crisis. This paper presents a discussion on the housing price cycle and abnormal price jumps to describe the behavior of housing prices in the United Kingdom. The empirical results show that the impact factors of housing cycles are market risk and the switching factor. Furthermore, the impact factors of jump risks include the bursting of the housing bubble and financial crises. Therefore, in this paper, we employ the Markov switching model with jump risks to value the MI contracts and analyze the influences of housing price cycles, jump risks, risks of market interest rate, and the prepayment risks on MI premiums. The results of sensitivity analysis show that more volatile housing price index returns, as well as longer periods of higher volatility in housing prices, raise MI premiums. Moreover, the MI premium is positively related to the absolute value of the average jump amplitude and the shock frequency of abnormal events. There is the tradeoff between the market interest rate and the prepayment risk. The influences of market interest rate are different on MI premium with/without prepayment risks. 相似文献
