China' s foreign-oriented oil taxation system has, from the beginning, been based upon the positive experiences of other oil-producing countries and has incorporated common international practices. The system has been perfected over decades. It of fers more incentives than other oil-producing countries in the following four aspects: (1) Income tax has a "wide tax base and low tax rate"; (2) VAT levies a low tax rate on ma- 相似文献

Applying jump-robust methods to estimating integrated volatility is in the mainstream of financial econometrics. However, little if any attention has been devoted to the construction of a jump-free estimator for integrated covariance that overlooks the well-documented manifestation of joint jumps. Joint jumps are contemporaneous within the day. Therefore, this study proposes a three-point approach that not only deals with estimating volatility, but also constructs a singular-jump-free and joint-jump-free covariance. Since the basic idea of the three-point covariance is based on conditional quantiles, we also provide two alternative procedures for finding approximated estimations in practical applications. Based on this approach, our empirical results confirm that singular jumps and joint jumps occur on the Taiwan Futures Exchange. 相似文献

税务代理范畴的界定根据国家税务总局《关于开展税务代理试点工作的通知》规定,税务代理是指税务代理人在法律法规规定的代理范围内,受纳税人、扣缴义务人的委托,代为办理税务事宜的各项行为的总称。根据我国加入WTO的法律性文件附件9《服务贸易具体承诺减让表》的规定,税务代理应归属于税务服务业。而按照《联合国中心产品分类》项目的划分,税务服务业(编号8630)包括企业税收计划编制和咨询服务(编号86301)、企业税收报表的编制和审阅服务(编号86302)、个人税收编制和计划服务(编号86303)、其他与税收相关的服务(编号86309)。从我国设置… 相似文献

This article investigates the duration-dependent feature of five Pacific Rim economies. The duration-dependent Markov Switching model is employed to achieve this objective. The Savage–Dickey density ratio is also computed in support of the duration-dependent Markov switching model. The possible bull and bear market dates for each stock market are also identified by the posterior probability from the empirical model. It is unambiguous that Japan, South Korea and Hong Kong are all characterized by duration-dependence in a bear market but no duration-dependence in a bull market. In the case of Taiwan and Singapore, the duration-dependence feature holds for both the bear and bull markets. 相似文献

The authors consider the absolute income effect and several relative income effects on happiness. The latter include both a longitudinal comparison, which consists of both upward and downward comparisons, and a parallel comparison with individuals of similar traits. It is found that the longitudinal comparison and parallel comparison exist simultaneously, although the downward comparison is insignificant. However, the symmetry of the upward comparison, downward comparison, and parallel comparison cannot be rejected. Because the absolute income effect and the relative income effects countervail, the effect of income growth on subjective well-being is likely to be negligible. 相似文献

Under both the overconfidence and disposition biases, a positive relationship is predicted between prior returns and subsequent trading volume. However, theoretically the overconfidence and disposition effects have different implications on the relationships between the long- and short-position gains of traders and their subsequent buying and selling activities. We examine a unique dataset obtained from the Taiwan Futures Exchange which records all account-level trades and orders. Our data and methodology have the advantage of being able to empirically differentiate these two effects and we demonstrate that different types of traders exhibit different types and levels of behavioral biases. 相似文献

We find that an important programming error was made by Hobijn and Franses ( 2000 ) in conducting multivariate stationarity tests. The empirical results in their paper are subject to errors. Other studies that have used the coded algorithm of Hobijn and Franses are likely to suffer the same problem. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

这些年来.国内钢材价格一直在上涨,尤其是近2年多来,价格涨势极为强劲。据测算,到2008年6月末.全国30个主要城市、五大品种的钢材平均价格为6263元/吨.比2005年末上涨106%.绝对吨价提高了3216元。受到供求关系以外多种因素的影响.预计一段时期内钢材价格仍将高位运行.并且不排除再创新高的可能。 相似文献
