Model Insight

Illiquidity shocks decay with a half-life of 7 trading days, meaning a shock loses half its impact after approximately 7 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.
