A new test for constant correlation is proposed. Based on the bivariate Student-t distribution, this test is derived as Lagrange multiplier (LM) test. Whereas most of the traditional tests (e.g. Jennrich, 1970, Tang, 1995 and Goetzmann, Li & Rouwenhorst, 2005) specify the unknown correlations as...

In this paper, we give an overview of the state-of-the-art in the econometric literature on the modeling of so-called financial point processes. The latter are associated with the random arrival of specific financial trading events, such as transactions, quote updates, limit orders or price...

We propose a general class of Markov-switching-ARFIMA processes in order to combine strands of long memory and Markov-switching literature. Although the coverage of this class of models is broad, we show that these models can be easily estimated with the DLV algorithm proposed. This algorithm...

This paper concerns goodness-of-fit test for semiparametric copula models. Our contribution is two-fold: we first propose a new test constructed via the comparison between "in-sample" and "out-of-sample" pseudolikelihoods, which avoids the use of any probability integral transformations. Under...

This paper applies a non- and a semiparametric copula-based approach to analyze the first-order autocorrelation of returns in high frequency financial time series. Using the EUREX D3047 tick data from the German stock index, it can be shown that the temporal dependence structure of price...

Are financial cycles an international phenomenon, and, if so, how do financial cycles interact? This letter provides new evidence for the US and the UK. Considering the properties of the data in both the time and the frequency domains, we find a strong relation between the financial cycles of...

Anchored inflation expectations are of key importance for monetary policy. If long-terminflation expectations arewell-anchored, they should be unaffected by short-termeconomic news. This letter introduces newsregressions with multiple endogenous breaks to investigate the de- and re-anchoring of...

Controllability of longer-term interest rates requires that the persistence of their deviations from the central bank's policy rate (i.e. the policy spreads) remains suciently low. This paper applies fractional integration techniques to assess the persistence of policy spreads of euro area money...
