We model the complex global dependencies in international financial markets using spatial techniques. Our methodology allows us to go beyond conventional correlation analyses and volatility-spillover models confined to studying pairwise relationships, and improves the accuracy of return...

The link between capital controls and stock market volatility is examined using frequency domain techniques. Conventional analyses of the second moments can produce spurious results if the high-frequency volatility is reduced (increased) while the overall volatility is increased (reduced)

This paper offers an empirical explanation behind the dynamics of the overall volatility of exchange rates and its high-frequency, most economically destabilizing components. Spectral methodology is employed to isolate the portion of volatility attributable to high-frequency components, and...

We use frequency-domain techniques, namely wavelets and cross-spectra, to examine the association between the daily prices of crude oil futures and daily S&P500 futures closing prices over the past several decades. We investigate contemporaneous and lag-lead relationships in levels and returns....
