Parameter Estimates

Dec 13, 1993 to Sep 24, 2026

Model Insight

With persistence 0.994, illiquidity shocks have a half-life of 117 trading days (~0.5 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. 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.
