The characterization of return distributions and forecast of asset‐price variability play a critical role in the study of financial markets. This study estimates four measures of integrated volatility—daily absolute returns, realized volatility, realized bipower volatility, and integrated...

Two recent nonlinear causality tests are used to examine the causal linkages across increasingly important international equity and commodity markets. We show that nonlinear causality is more appealing when asymmetric patterns are accounted for. The results are crucial to hedging and portfolio...

The study investigates the existence and extent of information rigidity in inflation forecasts among 25 developed and 18 developing economies during 2002-2017 period utilizing a survey data set never explored before on this issue. In general, the study finds some evidence of information...

The paper is the first attempt to estimate systematic risk ‘beta' at different time scales in the context of the emerging Gulf Cooperation Council (GCC) equity markets by applying a relatively new approach in finance known as wavelet analysis. Our results indicate that on average beta...

This study is the first attempt to investigate both the linear and non-linear Granger causality between wavelet transformed spot and futures oil prices. Our findings consistently indicate bidirectional causality between the spot and futures oil markets at different time scales, under linear and...
