Sep 26, 2002 to Sep 14, 2026Model Insight
With persistence 0.999, illiquidity shocks have a half-life of 533 trading days (~2.1 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.
