WebAug 1, 2024 · 1. Introduction. We are grateful for the opportunity to contribute to this special issue in honor of Luc Bauwens. Bauwens has made many contributions in econometrics, including to the literature on multivariate GARCH models, asymmetric volatility dependencies, and the use of high-frequency financial data, as exemplified by Bauwens … WebAutocorrelation in the conditional variance process results in volatility clustering. The GARCH model and its variants model autoregression in the variance series. Leverage effects. The volatility of some time series responds more to large decreases than to large increases. This asymmetric clustering behavior is known as the leverage effect.
