Abstract: We investigate the effect of publicly released announcements upon trade frequency using high frequency banking stocks from the Australian Stock Exchange and the Autoregressive Conditional Hazard (ACH) model of Hamilton and Jorda (2000). Unlike the ACD model, which models the timing of events, the ACH model focuses on the probability of events and facilitates the incorporation of fixed interval variables such as announcement indicators. This approach explicitly allows us to model the probability of trade in the presence of announcements. We find evidence to suggest that announcements increase the probability of trade
