The modeling of wind speed is a traditional topic in meteorological researches where the main interest is on the short term forecast of wind speed intensity and direction. More recently this theme has received some interest in the quantitative finance literature for its relations with the...

We define risk spillover as the dependence of a given asset variance on the past covariances and variances of other assets. Building on this idea, we propose the use of a highly flexible and tractable model to forecast the volatility of an international equity portfolio. According to the risk...

We propose a spatiotemporal approach for modeling risk spillovers using time-varying proximity matrices based on observable financial networks and introduce a new bilateral specification. We study covariance stationarity and identification of the model, and analyze consistency and asymptotic...
