This work quantifies the financial and macroeconomic effects of the most significant Brexit events from 23 June 2016 up to 31 December 2019 for fifteen economies. The study uses high-frequency data and shows that following the referendum outcome, overall the 10-year government bond yield of the...

This paper examines quantile dependence and directional predictability between the foreign exchange market and the stock market in Korea. Instead of adopting a multivariate model such as a vector autoregressive model, a multivariate GARCH model or a combination of both models, we apply the...

In this study, we examine the spillover of Bitcoin’s jumps and diffusive variations to traditional assets using high frequency data. For our cross-asset study, we detect positive spillovers from Bitcoin to risk assets and negative spillovers to defensive assets. We also find evidence of...

In this study, we examine the cross-excitation effects of Bitcoin’s jumps and diffusive variations on traditional asset classes using high frequency data. For our cross-asset study, we detect the presence of positive jump spillovers from Bitcoin to risk assets and negative jump spillovers from...

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...

The article discuss the relationship between US REITs and Japan REITs. In empirical study, we apply five static ARMAX-GJR-GARCH copula models and two time-varying dynamic copula models. The results show that the kendall tau is lower before the submortgage crisis. The contagion effect test...

The paper considers the problem as to whether financial returns have a common volatility process in the framework of stochastic volatility models that were suggested by Harvey et al. (1994). We propose a stochastic volatility version of the ARCH test proposed by Engle and Susmel (1993), who...

Empirical research confirms the existence of volatility spillovers across national stock markets. However, the models in use are mostly statistical ones. Much less is known about the actual transmission mechanisms; theoretical literature is scarce, and so is empirical work trying to estimate...

We examine the relationship between Islamic and conventional stock market returns to see if Islamic financial markets provide portfolio diversification benefits and safe havens during turbulent times. Using daily data from January 1996 through September 2020 we consider conventional emerging...
