We consider a Heston type inflation model in combination with a Hull–White model for nominal and real interest rates, in which all the correlations can be non-zero. Due to the presence of the Heston dynamics our derived inflation model is able to capture the implied volatility skew/smile,...

For high-dimensional risk aggregation purposes, most popular copula classes are too restrictive in terms of attainable dependence structures. These limitations aggravate with increasing dimension. We study a hierarchical risk aggregation method which is flexible in high dimensions. With this...

This outstanding collection of articles includes papers presented at the Fields Institute, Toronto, as part of the Thematic Program in Quantitative Finance that took place in the first six months of the year 2010. The scope of the volume in very broad, including papers on foundational issues in...

The current global COVID-19 pandemic is adversely affecting the oil market (West Texas Intermediate) and crypto-assets markets. This paper empirically investigates the extent to which interdependence in markets may be driven by COVID-19 effects. We fit copulas to pairs of before and after...

This paper applies cDCC model to compare the dynamic correlations between oil prices and exchange rates of G20 members. The significant shifts in the correlations are then endogenously detected. For each pair of oil price-exchange rate, empirical evidence confirms of a strengthening negative...

This paper tests the theoretical assumption of the foreign exchange market microstructure that dealers and non-dealer customers interact over discrete trading rounds. An exhaustive frequency-domain analysis reveals that the interaction is limited and mainly due to the instability of financial...

Using DCC-MIDAS model, we estimate the time-varying long-run correlations between crude oil and the major asset classes; then the structural changes in these correlations are determined with various methodologies. We reveal a strong positive (negative) secular trend toward higher correlation...

This paper conducts an investigation of volatility transmission between stock markets in Hong Kong, Europe and the United States covering the time period from 2000 up to 2011. Using intra-daily data we compute realized volatility time series for the three markets and employ a Heterogeneous...

Although it is essential for investors who want to comply with their religious obligations, cross-sectoral interaction in Islamic equity markets is an untouched subject in finance literature. Accordingly, this paper aims to investigate the interactions between the ten major sectors of Islamic...

Novel data-driven analyses, appropriate for detecting economic instability in non-stationary time series, are developed using functional principal component analysis (fPCA) and Synchrosqueezing. fPCA is applied in a new way, aggregating multiple financial time series to identify periods of...
