The paper develops a novel realized matrix-exponential stochastic volatility model of multivariate returns and realized covariances that incorporates asymmetry and long memory (hereafter the RMESV-ALM model). The matrix exponential transformation guarantees the positivedefiniteness of the...

We examine if the risk premia of the size effect on equity REITs (EREITs) are time-varying by using GARCH models. We also investigate how macroeconomic factors affect the size premia. We reexamine the size effect by using Fama-French three-factor model to demonstrate that the size effect exists...

This paper examines the effect of institutional ownership on stock volatility, returns, and dividend policy in Egypt. It also investigates the impact of dividend policy on the direction of the relation between institutional ownership and stock volatility and returns. Our main results show that...

This study explores the benefits of incorporating fat-tailed innovations, asymmetric volatility response, and an extended information set into crude oil return modeling and forecasting. To this end, we utilize standard volatility models such as Generalized Autoregressive Conditional...
