Jun 4, 2003 to Jul 17, 2026Model Insight
With persistence 1.000, illiquidity shocks have a half-life of 7146 trading days (~28.4 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.
Asymmetry: Illiquidity rises 261% more after negative returns
