The Role of Survey Data in Nowcasting Euro Area GDP Growth

This paper evaluates the impact of new releases of financial, real activity and survey data on nowcasting euro area gross domestic product (GDP). We show that all three data categories positively impact on the accuracy of GDP nowcasts, whereby the effect is largest in the case of real activity data. When treating variables as if they were all published at the same time and without any time lag, financial series lose all their significance, while survey data remain an important ingredient for the nowcasting exercise. The subsequent analysis shows that the sectoral coverage of survey data, which is broader than that of timely available real activity data, as well as their information content stemming from questions focusing on agents' expectations, are the main sources of the ‘genuine’ predictive power of survey data. When the forecast period is restricted to the 2008–09 financial crisis, the main change is an enhanced forecasting role for financial data. Copyright © 2015 John Wiley & Sons, Ltd.     

欧美股票市场对我国股票市场的传染效应研究——基于次贷与欧债危机背景

近年来,金融危机频频爆发且易表现出传染性,这使得金融传染引起国内外学者的高度关注.本文选取合适的动态条件相关模型研究欧美市场与A股、港股市场的条件相关性,结合内生多重结构突变模型与T检验方法划分危机传染期与平稳期,选用考虑外部影响的CCK模型研究A股、港股市场的羊群行为,随后,引入收益率分散度指标,研究两次危机的羊群行为传染渠道.研究结果表明:港股市场受两次危机传染的速度均快于A股市场,受传染的持续时间均长于A股市场,但受传染的程度均弱于A股市场:次贷危机传染程度强于欧债危机的传染程度,但传染的持续时间短于欧债危机:羊群行为传染渠道是两次危机对A股、港股市场的传染渠道之一.     

Forecasting the Daily Time‐Varying Beta of European Banks During the Crisis Period: Comparison Between GARCH Models and the Kalman Filter

This intention of this paper is to empirically forecast the daily betas of a few European banks by means of four generalized autoregressive conditional heteroscedasticity (GARCH) models and the Kalman filter method during the pre‐global financial crisis period and the crisis period. The four GARCH models employed are BEKK GARCH, DCC GARCH, DCC‐MIDAS GARCH and Gaussian‐copula GARCH. The data consist of daily stock prices from 2001 to 2013 from two large banks each from Austria, Belgium, Greece, Holland, Ireland, Italy, Portugal and Spain. We apply the rolling forecasting method and the model confidence sets (MCS) to compare the daily forecasting ability of the five models during one month of the pre‐crisis (January 2007) and the crisis (January 2013) periods. Based on the MCS results, the BEKK proves the best model in the January 2007 period, and the Kalman filter overly outperforms the other models during the January 2013 period. Results have implications regarding the choice of model during different periods by practitioners and academics. Copyright © 2016 John Wiley & Sons, Ltd.     

The US Dollar/Euro Exchange Rate: Structural Modeling and Forecasting During the Recent Financial Crises

The paper investigates the determinants of the US dollar/euro within the framework of the asset pricing theory of exchange rate determination, which posits that current exchange rate fluctuations are determined by the entire path of current and future revisions in expectations about fundamentals. In this perspective, we innovate by conditioning on Fama–French and Carhart risk factors, which directly measures changing market expectations about the economic outlook, on new financial condition indexes and macroeconomic variables. The macro‐finance augmented econometric model has a remarkable in‐sample and out‐of‐sample predictive ability, largely outperforming a standard autoregressive specification. We also document a stable relationship between the US dollar/euro Carhart momentum conditional correlation (CCW) and the euro area business cycle. CCW signals a progressive weakening in economic conditions since June 2014, consistent with the scattered recovery from the sovereign debt crisis and the new Greek solvency crisis exploded in late spring/early summer 2015.

危机信息传播有效性的离散化不确定性评估模型

以科学评估危机信息传播有效性为目标,结合国内外前沿文献对危机信息传播的影响因素和传播过程的不确定性进行了分析论述。分析认为,危机信息传播有效性是一个不确定性概念,是模糊性与随机性的统一;其评估问题也需要从模糊性与随机性两个方面结合进行考虑。应用模糊随机理论,构建了危机信息传播有效性的离散化评估模型,并给出了隶属函数的确定方法。这是对危机信息传播有效性评估理论与方法的拓展,为危机信息传播有效性的定量研究提供了思路。

超越自我的荆棘之路——论《金色笔记》中安娜的精神探索

多丽丝.莱辛的《金色笔记》自问世以来不断受到评论界的关注,人们对它的研究大部分从作品的形式和内容层面着手.在研究内容这一领域,人们对它的解读首先是从女性主义的角度入手的.毋庸置疑,《金色笔记》叙述的是女主人公安娜的精神发展历程,不可避免地有女性主义色彩的存在,但是,这部作品的伟大之处不仅是因为作品的女性视角,更重要的是作家莱辛站在“入”这个更广泛的角度来探索主人公的精神发展历程.
