Econometrics lies at the intersection of statistics, economics, and computer science. Essentially, it uses computers to apply statistics to study economics. The primary goal of this course is to introduce you to econometrics and thereby help you become an intelligent consumer of statistics and its application to economics. Throughout the course, there will be a strong effort to keep a good balance between statistics, computing, and economics - but the first part of the course will be weighted more towards statistics, and the second towards economics.
The first part of the course reviews basic statistics, then works out the theory of the most widely used econometric technique, known as multiple regression analysis. The second part of the course turns to applications, with four weeks devoted to applying econometrics to four different substantive economic questions.
You must have competence in basic statistics to succeed in this course. In the first class, you will be provided with a take-home pre-test to see if your preparation is adequate. You will also need to be reasonably familiar with basic micro and macroeconomics.
This class will make extensive use of PC computing using Eviews. I do not assume familiarity with computer programming, but you must know (or be willing to teach yourself) the basics of using the World Wide Web (e.g., how to go to a website, and how to save files from a webpage).
The main text is a reader copying selections from T. Dudley Wallace and J. Lew Silver, Econometrics: An Introductio. For homework and supplemental reading, you will also need David Freedman and David Love, Mathematical Methods in Statistics: A Workbook.
In addition, you must purchase a copy of Eviews; the best place to do so is surely online at http://www.eviews.com/general/prices.html. The price is $65 for the Student version; once you are sure you will be in the class, order it immediately.
Other materials will be provided on my webpage or in lecture.
Grading and Exams:
There will be one midterm and a final exam - essentially, an exam for each Part of the course. The midterm counts 30%; the final exam is 40%; homework counts for the remaining 30%. These weights are fixed - improvement on later exams will not retroactively raise your grades on earlier exams.
There is no formal grade for participation, but if you are one of the students who (in my judgment) contributes most to the quality of class discussion your grade will be raised if you are on the border between two grades.
There will be approximately six homework assignments during the semester. You will probably find the class very hard to follow if you fail to spend sufficient time on all of the homeworks. Depending upon how good a job you do, your homework will receive a check-plus (4 points), a check (3 points), or a check-minus (2 points) if you turn it in; otherwise you receive 0 points. Late homework loses one point. Late homework is no longer accepted after I pass out my suggested answers for a given assignment.

My proposed schedule for the semester follows. If it proves too ambitious, I will try to simply say less about each topic rather than cut the topics for the final weeks.
