Jul 18, 2008 to Nov 2, 2026Model Insight
With persistence 1.000, illiquidity shocks have a half-life of 18733 trading days (~74.3 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 responds almost entirely to negative returns
