This script (January 01, 3 pages) reviews some basic equations concerning VAR estimation and impulse-response functions with constant and time trend. The following VAR(2) is used as illustration

This short script (January 01, 14 pages) reviews the basic optimal growth model solutions with and without dynamic programming in discrete time for nonstochastic and stochastic cases. We use the same simple textbook model for all cases in order to allow for comparisons

This script (Fall 00, 21 pages) reviews basic concepts in statistics and econometrics. Further explanations and proofs can be found in the reference given at the end of this text. This refresher is complemented by a numerical example (Fall 98, 11 pages) in monetary economics in a separate manuscript. This script serves as an introduction for Central Bankers Courses
