Newey and Smith [Newey, W.K., Smith, R.J., 2004. Higher order properties of GMM and empirical likelihood estimators. Econometrica 72, 219-255] analyzed the second order biases of GMM and GEL estimators under independence. Anatolyev [Anatolyev, S., 2005. GMM, GEL, serial correlation, and...

Kinal (1980) showed that k-class estimators for which k  1 possess all necessary higher moments. A bias approximation to order T- 2 is derived for the general k-class estimator extending the earlier result for 2SLS of Mikhail (1972) thus improving our knowledge of a potentially...

In this paper we use the approximate bias expressions developed in Yu (2012) and Bao et al. (2013) to improve the testing of the ordinary least squares or quasi-maximum likelihood estimator of the mean reversion parameter in continuous time models. We follow the approach given in Iglesias and...
