AsymptoticFandttests in an efficient GMM setting

Abstract: This paper considers two-step e¢ cient GMM estimation and inference where the weighting matrix and asymptotic variance matrix are based on the series long run variance estimator. We propose a simple and easy-to-implement modi…cation to the trinity of test statistics in the two-step e¢ cient GMM setting and show that the modi…ed test statistics are all asymptotically F distributed under the so-called …xed-smoothing asymptotics. The modi…cation is multiplicative and involves the J statistic for testing over-iden… Show more

“…The fixed-smoothing asymptotic distributions are nonstandard in both kernel and OS cases. For the OS case, Hwang and Sun (2017) show that a modified Wald statistic is asymptotically F distributed and that a modified t statistic is asymptotically t distributed. More specifically, the modified Wald and t statistics are given by…”

“…More recently, researchers established fixed-smoothing asymptotics in a general two-step GMM framework. See Sun and Kim (2012), Sun (2013Sun ( , 2014b, and Hwang and Sun (2017). The key difference between first-and two-step GMM is that in two-step GMM, the HAR variance estimator not only appears in the covariance estimator but also plays the role of the optimal weighting matrix in the second-step GMM criterion function.…”

“…This paper contributes to the literature on the …xed-smoothing asymptotics in general and the asymptotic F and t test theory in particular. The asymptotic F and t tests have been developed in Sun (2011) for linear trend regressions, in Sun (2013) for stationary moment processes, in Sun (2014c) for highly persistent moment processes, in Hansen (2007) for stationary panel time series, and in Hwang and Sun (2017) for stationary data in an overidenti…ed GMM framework. Lazarus, Lewis, Stock, and Watson (2016) provide some practical guidance on the F and t tests for time series regressions.…”
