摘要: Recent research has suggested that intra-day volatility may contain both short-run and long-run components due to the existence of heterogeneous information flows or market agents (Andersen & Bollerslev, 1997a, 1997b; Muller et al., 1997). We report direct evidence for such a decomposition in UK FTSE-100 futures returns data at frequencies one hour higher using permanent–transitory component variance model Engle Lee (1993). Moreover, transitory identified exhibits rapid decay, half-day frequency being completely dominated by highly persistent permanent component. The also is able capture all dependency within lower. © 2000 John Wiley Sons, Inc. Jrl Fut Mark 20:425–444,
