We establish strict stationarity and strong mixing properties of the dynamic Tobit process. Using these results we show that the regularity conditions for bias corrections in general non-linear dynamic panel models are satisfied for the dynamic Tobit model.

Comparisons of within and between estimators using the conventional Hausman test may be subject to statistical problems if the within variation is not sufficiently large. Adopting an alternative asymptotic approximation, we propose a modification of Hausman test that is valid whether the within...
