J. Gonzalo et Jy. Pitarakis, ON THE EXACT MOMENTS OF ASYMPTOTIC DISTRIBUTIONS IN AN UNSTABLE AR(1)WITH DEPENDENT ERRORS, International economic review, 39(1), 1998, pp. 71-88
In this paper we derive the exact moments of asymptotic distributions
of the OLS estimate and t-statistic in an unstable AR(1) with dependen
t errors. We also study the relationship between the number of lagged
dependent variables required for matching the distribution moments in
the 'approximately i.i.d. errors' model with those occurring in the 'p
urely i.i.d.' model.
