This paper applies a set of GARCH models to investigate the three characteristics, including time persistence, leverage effect, and risk premium, of the volatilities of the four China Securities Index (CSI) fund indices. This study made the following four findings: (1) a strong ARCH effect exists in the returns; (2) time persistence is significant in all the CSI fund indices, namely, "stock index," "hybrid index," and "bond index" in descending order of significance; (3) the leverage effect is not statistically significant, yet there may be a positive leverage effect on the bond funds; (4) a risk premium effect exists in the open-end fund market, especially in the bond fund market.  相似文献

This article deals with the analysis of house price indexes from a long-range dependence viewpoint. In particular, it estimates the fractional differencing parameter in the London and Paris house price series recognizing in some cases the potential seasonality and allowing for breaks in the data. Moreover, it analyses the stability of the parameters across the sample period examined. It is concluded that the series are nonstationary but mean reverting in some cases and very persistent in others. Policy implications are derived.  相似文献

Using income tax administrative data for Australia, we examine levels and trends in the persistence in top-income group membership, focusing on the top 1 percent. Top-income persistence increased markedly between 1991 and 2018, with most of the increase occurring in the mid-2000s and early 2010s. In the mid- to late-2010s, Australian top-income persistence rates were near the top of the range of tax-data estimates for other countries. We decompose the increase into factors associated with (i) changes in the composition of the top-income group and (ii) increases in persistence rates for specific population subgroups. We find that the rise in top-income persistence is accounted for by changes in subgroup persistence rates, notably for individuals aged 35–64, and especially those aged 55–64. We suggest that these effects are partially related to increases in the effective retirement age over the relevant period.  相似文献

通过构建基于熵模型计量的内部控制信息披露质量指数,以净资产收益率、总资产收益率、每股盈余、经营业绩指数以及托宾Q值为公司经营业绩的代理变量,实证检验我国现阶段内部控制信息披露质量与上市公司经营状况之间的关系后发现:除了托宾Q值的检验未通过以外,其他检验结果均显示内部控制信息披露质量越高的公司,经营业绩越好;反之,内部控制信息披露质量越差的公司,经营业绩越差。这说明现阶段我国上市公司披露的内部控制信息已经具备了一定的决策有用性。  相似文献

This paper examines the degree of persistence in international monthly arrivals to Australia by using data disaggregated by tourism‐source countries. We employ two competing models, which are very general in the sense that they include (seasonal and non‐seasonal) unit roots as particular cases of interest. The first model is based on a long‐memory process in the non‐seasonal part of the series along with a short‐memory autoregressive (AR) seasonal structure. The second model is based on a long‐memory process for the seasonal structure of the series, the short‐term evolution being described through a non‐seasonal AR(1) process. Results based on the residuals and forecasting assessment indicate that the second model is preferable in terms of fitting the data. We provide persistence ranking of all countries included in the study and discuss the managerial implications of the main findings. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

运用中国营养与健康调查两个横截面的数据研究了农村劳动力收入的性别差异及其变化情况。农村男女劳动力收入方面存在着明显的性别差异,并且有扩大的趋势。工资回报差异的上升是性别收入差距扩大的主要原因,来自自雇劳动方面的差异则表现为先扩大后缩小收入差距的特点,农业劳动影响不大。  相似文献

改进后扩展琼斯模型与其他盈余管理计量模型的比较研究   总被引:4,自引:0,他引:4  
基于公允价值的理念提出了一种计量盈余管理的新的模型——改进后扩展琼斯模型。这一模型主要是在计量总应计利润时扣除了资产减值准备对盈余的影响,并在修正琼斯模型的基础上,考虑了无形资产对计量盈余管理的影响。利用我国上市公司2003年到2006年的数据,通过改进后扩展琼斯模型与其他盈余管理计量模型的比较分析,发现改进后扩展琼斯模型检定盈余管理的效果更加显著。  相似文献

This study estimates the changes in volatility of the won/U.S. dollar dailyexchange rates before and after the Korean currency crisis, using the stochastic volatility model with the ARMAregression error term. We find that the persistence of volatility increased after the Koreancurrency crisis.  相似文献

In a recent paper, Giugale and Korobow (2000) present evidence that suggests that the time required by output to return to trend following a financial shock is faster under a flexible exchange rate regime than under a fixed exchange rate. In this paper, we use vector autoregression models to measure the persistence properties of output for a number of countries in the Asia–Pacific region. Our results suggest that output persistence is not uniquely related to a country's choice of exchange rate regime. The two countries in our sample with the least persistent output following a financial shock are Australia, where the exchange rate is fully flexible, and Hong Kong, where it is rigidly fixed via a currency board.  相似文献
