Parameter Estimates

Oct 29, 2003 to Sep 4, 2026

Model Insight

With persistence 0.998, illiquidity shocks have a half-life of 347 trading days (~1.4 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.
