Title: Long-memory in volatilities of German stock returns
Language (ISO): en
Abstract: We show that there is strong evidence of long-range dependence in the volatilities of several German stock returns. This will be done by estimating the memory parameter of the absolute returns with classical log-periodogram regression as well as by employing the tapered periodogram. Both estimators give similar values for the memory parameter what indicates long-memory.
