We combine the global Hurst exponent and Morlet wavelet multi-resolution analysis (MRA) to investigate the dynamic behaviour of six selected stock markets in the Mediterranean region. Specifically, we employ the resonance coefficients and their power spectra to identify potential extreme...

We investigate the dynamics of regional financial integration and its determinants in the context of an ICAPM accounting for the deviations from PPP as well as temporal variations in both regional and local sources of risk. Using data from four major countries of the Southeast Europe, our...

This article investigates the potential of nonlinear causal relationships between world oil prices and stock markets in Middle East and North Africa (MENA) countries during a black swan period that is characterized by rarity and devastating impacts. Our study is carried out using the daily data...

This article estimates the number of breaks and their locations in the covariance structure of a series based on the evolutionary spectral density and uses some standard information criteria. The adopted approach is non-parametric and does not privilege a priori any modelling of the series. One...
