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...

We study the stock return comovements from two different perspectives, one being trading behaviour-induced return comovements and the other volatility-induced return comovements. Following Baker and Wurglur (2006), we construct an investor sentiment index and examine whether it has relationship...

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...

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...

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...

Identifying risk spillovers in financial markets is of great importance for assessing systemic risk and portfolio management. Granger causality in tail (or in risk) tests whether past extreme events of a time series help predicting future extreme events of another time series. The topology and...

This paper introduces technological interdependence à la Ertur and Koch (Growth, technological interdependence and spatial externalities: Theory and evidence. Journal of Applied Econometrics 2007; 22: 1023-1062) into the theoretical framework of Gennaioli et al. (Human capital and regional...

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...
