SYLLABUS: ECONOMICS 141 (Section 1) INTRODUCTION TO ECONOMETRICS SPRING 2013 INSTRUCTOR: OFFICE: PHONE: CLASS HOURS: E-MAIL: OFFICE HOURS: WEB SITE: Professor Craig Gallet Tahoe 3024 278-6099; 278-5768 (Fax) T/TH 9-10:15am (Tahoe 1027) cgallet@csus.edu T/TH 10:30-11:45am; T 1:15-1:45pm; or by appointment http://www.csus.edu/indiv/g/galletc/ PREREQUISITES: Introductory Macroeconomics and Microeconomics (i.e., ECON 1A and 1B, or their equivalents), Quantitative Economic Analysis (i.e., ECON 140 or its equivalent), and either Intermediate Macroeconomics or Microeconomics (i.e., ECON 100A or 100B, or an equivalent) TEXTS: Required: Using Econometrics: A Practical Guide, 6th Edition (2011), by Studenmund. Required: Transparencies to Accompany Lectures Recommended: Student version of Eviews (version 6.0 or higher). Since this course is data-intensive, we will use software to perform much of the statistical analyses presented. Although you are welcome to use whatever software you like, during lab time I will use Eviews 7. Also, homework keys will be written using Eviews procedures. You can buy the student version of Eviews at http://www.eviews.com/index.html. The full version of Eviews is also available at a substantial discount. Regarding other possible software, Excel can be used to perform many of the calculations we will do throughout the semester. However, it is tedious to use and will not be able to perform calculations related to topics discussed later in the term. The university does hold a site license for Stata if you want to use it. Also, you could download a free copy of Gretl at http://gretl.sourceforge.net/. For these alternative software options, since I have had limited exposure to them I will not be able to provide much assistance should you get “stuck”. GRADING: Percentage of Course Grade Three equally-weighted exams Several homework exercises Several group/individual activities 70% 25% 5% The following expected grade scale will be used in this class: Percentage of Weighted Points Possible 90-100 80-89 70-79 60-69 < 60 Grade Range A’s (A, A-) B’s (B-, B, B+) C’s (C-, C, C+) D’s (D-, D, D+) F’s Note: If scores are below expectations, the instructor reserves the right to “adjust the curve” accordingly. Also, this class will adhere to all CSUS policies regarding academic behavior. Exams will consist of problems you will analyze using the tools learned in the course. Make sure to always have a non-programmable calculator available. Many of the homework exercises will utilize Excel data files that you will download from my website and analyze. Exams and homework exercises are graded on a 100-point scale, while group/individual activities are graded on a plus (+), check (), or minus (-) system [As long as you receive a plus or a check, you will receive full credit on the group/individual activities. However, a minus will give you no credit.]. No late homework’s will be accepted. Note: Some topics I will discuss are not in the book. As such, it is expected that all students will attend each class meeting. Indeed, several (if not all) of the group/individual activities will occur during class; and for every two group/individual activities missed, without prior permission, in addition to foregoing points associated with those activities, your weighted point total for the course will be reduced 5 percent. And so, for example, let’s say there were 10 individual/group activities throughout the term and you missed all 10 without prior permission. Accordingly, you would have missed 5% of the weighted points possible due to missing those activities, and coupled with the 25% penalty for missing the 10 in-class assignments, at best you could hope for a C- in the course (assuming you receive 100% of the points possible on the exams and homework exercises, which is highly unlikely). Note: The computer lab in Mariposa 1011 is reserved for the following (tentative) date: February 14. IMPORTANT DATES: Exam 1: Exam 2: Exam 3: March 5 April 16 May 21 (10:15am-12:15pm) Computer Lab: February 14 No Class: March 26, 28 (Spring Break) CALCULATOR: Make sure to bring a non-programmable calculator on exam days. PURPOSE AND OBJECTIVES: The purpose of this course is to introduce you to the fundamentals of econometrics (i.e., regression analysis applied to economic issues). Regression is a powerful statistical tool used by many decision-makers to assess the relationships between various factors. Accordingly, the course objectives are: To develop an understanding of the process followed when building an econometric model. To apply econometric tools to data utilizing statistical software. To develop an understanding of diagnostic tools. LECTURE OUTLINE I.
