Jun 12, 1997 to Nov 6, 2026Model Insight
Illiquidity shocks decay with a half-life of 5 trading days, meaning a shock loses half its impact after approximately 5 days. 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.
