In this paper we want to discuss macroscopic and microscopic properties of financial markets. By analyzing quantitatively a database consisting of 13 minute per minute recorded financial time series, we identify some macroscopic statistical properties of the corresponding markets, with a special...

This paper uses a frequency domain approach to gain insight into the correlation between survey indicators and year … of the correlation between survey indicators and year-on-year GDP growth at the different frequencies to explain their … overall correlation. We show that survey indicators, similar to year-on-year GDP growth, do not perfectly reflect business …

We extend the fractionally integrated exponential GARCH (FIEGARCH) model for daily stock return data with long memory in return volatility of Bollerslev and Mikkelsen (1996) by introducing a possible volatility-in-mean effect. To avoid that the long memory property of volatility carries over to...

Recent studies suggest that the correlation of stock returns increases with decreasing geographical distance. However …, there is some debate on the appropriate methodology for measuring the effects of distance on correlation. We modify a … regression approach suggested in the literature and complement it with an approach from spatial statistics, the mark correlation …

The Chinese stock market features an interesting history of divided market segments: domestic (A), foreigners' (B) and overseas (H). This puts forth questions of market integration as well as cross-divisional information transmission. We address these issues in a structural DCC framework, an...

We investigate the possibility of exploiting partial correlation graphs for identifying interpretable latent variables … underlying a multivariate time series. It is shown how the collapsibility and separation properties of partial correlation graphs …

There is increasing demand for models of time-varying and non-Gaussian dependencies for mul- tivariate time-series. Available models suffer from the curse of dimensionality or restrictive assumptions on the parameters and the distribution. A promising class of models are the hierarchical...
