Mar 28, 1994 to Nov 22, 2021Model Insight
With persistence 0.998, illiquidity shocks have a half-life of 383 trading days (~1.5 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.
Asymmetry: Illiquidity rises 126% more after negative returns
