On bootstrapping panel factor series

Trapani, L. (2013). On bootstrapping panel factor series. Journal of Econometrics, 172(1), pp. 127-141. doi: 10.1016/j.jeconom.2012.09.001


This paper studies the asymptotic validity of sieve bootstrap for nonstationary panel factor series. Two main results are shown. Firstly, a bootstrap Invariance Principle is derived pointwise in i, obtaining an upper bound for the order of truncation of the AR polynomial that depends on n and T. Consistent estimation of the long run variances is also studied for (n,T)→∞. Secondly, joint bootstrap asymptotics is also studied, investigating the conditions under which the bootstrap is valid. In particular, the extent of cross sectional dependence which can be allowed for is investigated. Whilst we show that, for general forms of cross dependence, consistent estimation of the long run variance (and therefore validity of the bootstrap) is fraught with difficulties, however we show that "one-cross-sectional-unit-at-a-time" resampling schemes yield valid bootstrap based inference under weak forms of cross-sectional dependence.
