May 8, 2013 to Aug 14, 2026Model Insight
With persistence 1.000, illiquidity shocks have a half-life of 693147 trading days (~2750.6 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.
