2012年4月17日,美国国际贸易委员会做出裁决,美国工业界没有因从中国进口的特定钢制车轮而蒙受实质性损失或威胁,因此取消对中国向美同出口刚制车轮征收的反倾销和反补贴关税。这一裁决被视为颇为罕见。 相似文献

美国商务部2007年3月30日公告了对中国铜版纸产品反补贴调查的初裁结果,决定对中国出口美国的铜版纸产品征收10,9%~20.4%的临时反补贴税。这是美国23年来首次对“非市场经济国家”进口的产品征收反补贴税。面对美方此种态度,中国政府随即表示了强烈不满。[第一段] 相似文献

An Investigation of Event Study Methodologies with Clustered Events and Event Day Uncertainty 总被引:1,自引:1,他引:0
The specification and power of mean-adjusted, market and quadratic models in event studies using OLS, Patell, Jaffe and GLS are examined. Simulation is used with security and portfolio returns to capture different cross correlations. The market model is always superior in specification and power compared to the mean-adjusted and quadratic models. The use of OLS with the market model is supported in the absence of clustered events and event day uncertainty, whereas use of Jaffe with the market model is supported in the presence of these problems. 相似文献

Event studies: A methodology review 总被引:1,自引:0,他引:1
Charles J. Corrado 《Accounting & Finance》2011,51(1):207-234
Originally developed as a statistical tool for empirical research in accounting and finance, event studies have since migrated to other disciplines as well, including economics, history, law, management, marketing, and political science. Despite the elegant simplicity of a standard event study, variations in methodology and their relative merits continue to attract attention in the literature. This paper reviews some of the fundamental topics in short‐term event study methodology, with an attempt to add new perspectives to some pressing topics. 相似文献

Event studies have been used to examine the direction, magnitude, and speed of security price reactions to various phenomenon. Concerns over the lack of normality in stock return distributions motivated the introduction of nonparametric test statistics in the event study literature. A parametric procedure (OLS), however, has been extensively employed in the estimation of parameters for the market model. This paper, in contrast, applies Theil's nonparametric regression in the estimation of abnormal returns; an approach which is distribution free and provides a complete nonparametric approach for the detection of abnormal performance. Simulation results indicate Theil's estimation procedure offers a slight improvement in power in the detection of abnormal performance over the traditionally employed methodology. The results suggest employing Theil's nonparametric estimation procedure combined with the rank statistic. This complete nonparametric combination offers similar power with fewer underlying assumptions. 相似文献

Dynamic Asset Allocation with Event Risk 总被引:15,自引:0,他引:15
Major events often trigger abrupt changes in stock prices and volatility. We study the implications of jumps in prices and volatility on investment strategies. Using the event-risk framework of Duffie, Pan, and Singleton (2000), we provide analytical solutions to the optimal portfolio problem. Event risk dramatically affects the optimal strategy. An investor facing event risk is less willing to take leveraged or short positions. The investor acts as if some portion of his wealth may become illiquid and the optimal strategy blends both dynamic and buy-and-hold strategies. Jumps in prices and volatility both have important effects. 相似文献

The Event Study Methodology Since 1969 总被引:15,自引:3,他引:12
John Binder 《Review of Quantitative Finance and Accounting》1998,11(2):111-137
This paper discusses the event study methodology, beginning with FFJR (1969), including hypothesis testing, the use of different benchmarks for the normal rate of return, the power of the methodology in different applications and the modeling of abnormal returns as coefficients in a (multivariate) regression framework. It also focuses on frequently encountered statistical problems in event studies and their solutions. 相似文献
