This workbook is not a substitute for the material in Macroeconometric Modeling, and this material should be read (or at least skimmed) first. Also, you should have familiarity working with the US model before you begin working with the MC3 model. Chapter 1 of this workbook discusses a few practical things you should know when working with the MC3 model, and the rest of the workbook consists of examples using the model.
