In this article we provide evidence for a rational bubble in S\&P 500 stock prices by applying a test for changing persistence under fractional integration proposed by Sibbertsen and Kruse (2007). We find strong evidence for stationary long memory before the estimated change point in 1955 and a...

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...

We examine the dynamics of bank lending to the private sector for countries of the Euro area by applying a Markov switching error correction model. We identify for Belgium, Germany, Ireland and Portugal stable, mean reverting regimes and unstable regimes with no tendency to return to the long...
