Oct 16, 2007 to Sep 18, 2026Model Insight
Illiquidity shocks decay with a half-life of 4 trading days, meaning a shock loses half its impact after approximately 4 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.
