英文摘要:
This paper investigates the presence of long memory in corporate bond and stock indices of six European Union countries from July 1998 to February 2015. We compute the Hurst exponent by means of the DFA method and using a sliding window in order to measure long range dependence. We detect that Hurst exponents behave differently in the stock and bond markets, being smoother in the stock indices than in the bond indices. We verify that the level of informational efficiency is time-varying. Moreover we find an asymmetric impact of the 2008 financial crisis in the fixed income and the stock markets, affecting the former but not the latter. Similar results are obtained using the R/S method.

本文调查了1998年7月至2015年2月六个欧盟国家的公司债券和股票指数中是否存在长记忆。我们通过DFA方法计算赫斯特指数,并使用滑动窗口来测量长程依赖性。我们发现赫斯特指数在股票和债券市场中的表现不同,股票指数比债券指数更平稳。我们验证了信息效率水平是时变的。此外,我们发现2008年金融危机对固定收益和股票市场的影响是不对称的,前者受到影响,但后者没有受到影响。用R/S方法也得到了类似的结果。
