摘要：
Pure-jump stochastic processes are shown to be capable of explaining many empirical features of high-frequency asset prices. A simple pure-jump process can match the empirical bipower variation, realized variance and jump detection statistics of Andersen, Bollerslev and Dobrev (2007) at the two-minute frequency. A multi-frequency analysis of Spyder returns shows the theoretical predictions can also be aligned reasonably accurately with the empirical evidence across more than one sampling frequency.
