To estimate OHR, we employ multivariate BEKK MV-GARCH model. At last, the efficiency of this approach are compared with the constant OHR captured from OLS through Edrington's index.}, keywords = {Erdöl; crude oil; Rohstoff; raw materials; Markt; market; Risikomanagement; risk management; Preis; price}}
