Parameter Estimates

Mar 31, 2016 to Sep 18, 2026

Model Insight

With persistence 0.990, illiquidity shocks have a half-life of 69 trading days (~0.3 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.

Asymmetry: Illiquidity rises 32% more after negative returns
