This is a good econometrics book at the beginner level that will give most students a solid base to start with. However, it only glimpses some advanced or very specific topics and is a little outdated. Well written, with good demonstrations, although not intended to cover in full all the details. Readers interested in more advanced topics are encouraged by the authors to follow other bibliography (Greene, for example). And it covers forecasting and time series models, what some books at this level do not cover very well.
