r Economics 6818, Econometrics, Spring 1998 Lectures: Monday, Wednesday Room 5, 11:30-12:45. Ron Smith, Room 203, Email:[email protected]; Tel: 482-8295 Office Hours, M W F 1:45-2:45. Textbook: Basic Econometrics, D N Gujarati, 3rd edition, denoted G below. You should also look at Peter Kennedy, A Guide to Econometrics, 3rd edition; K below. This is not a text book, but students usually find it very useful in explaining what econometrics is all about. Objectives: This course will provide an introduction to basic econometric techniques and experience in using these techniques to answer real world questions. It will require basic mathematics (algebra, calculus and matrix algebra), elementary descriptive and mathematical statistics and intermediate economics. It will provide some revision of this material as it is used. Assessment. One mid-term, one computer exercise on data provided (using EViews or any other program you prefer), one final exam and one 2,000 word empirical term paper on a topic of your own choice (each worth a quarter of the final grade). Exercises and a computer assignment will be distributed. Provisional Outline. We may not be able to cover all this. Introduction to Econometrics: What are we trying to do. G Chapter 1.
