Asymptotic expansions are employed in a dynamic regression model with a unit root inorder to find approximations for the bias, the variance and for the mean squared error of theleast-squares estimator of all coefficients. It is found that in this particular context suchexpansions exist only when...

Using the same model that Caballero-Urdiales {\it et al.} (2012) and Brito-Gaona and Iglesias (2017) applied to Latin-American countries, we extend their analysis to the European Union (EU) in order to analyze the determinants of private investment. Results show consistent evidence with three...

We propose two simple bias reduction procedures that apply to estimators in a general static simultaneous equation model and which are valid under reatively weak distributional assumptions for the errors. Standard jackknife estimators, as applied to 2SLS, may not reduce the bias of the exogenous...
