Apr 24, 1998 to Jul 24, 2026Model Insight
Illiquidity shocks decay with a half-life of 1 trading day, meaning a shock loses half its impact after approximately 1 day. This multi-frequency model splits illiquidity into a fast short-run component and a slow-moving long-run level that drifts over the sample rather than a constant baseline.
