COURSE DESCRIPTION

This course introduces students to multiple regression methods for analyzing data in economics and related disciplines.  Extensions include regression with discrete random variables, instrumental variables regression, analysis of random experiments and quasi-experiments, and regression with time series data.  The objective of the course is for the student to learn how to conduct – and how to critique – empirical studies in economics and related fields.  Accordingly, the emphasis of the course is on empirical applications.  The mathematics of econometrics will be introduced only as needed and will not be a central focus. 

PREREQUISITES

Microeconomic Principles (50:220:102 ) AND Macroeconomic Principles (50:220:103 ) AND Introduction to Statistics I (50:960:283 ).

TEXTBOOK AND SOFTWARE

The text for this course is: Introductory Econometrics: A Modern Approach, 6th Edition

By Jeffrey M. Wooldridge. And here is the bundle that you need to purchase:
Wooldridge – Bundle: Introductory Econometrics: A Modern Approach, Loose-leaf Version, 6th + LMS Integrated for MindTap® Economics, 1 term (6 months) Printed Access Card
| 9781337127134.

The software that will be used in this course is STATA. The software is available at most of public labs on campus. Some labs are open in the evening and at the weekend. No prior knowledge of this software package is assumed. Also a helpful handout on how to use STATA is posted on the course website.

INSTRUCTIONS ON ACCESSING STATA:

You can either purchase STATA directly from the manufacture from the following link; http://www.stata.com/order/new/edu/gradplans/, or use it on campus. If you are on campus, you can easily access STATA on most public labs on campus. But if you are off campus, you can access STATA by using the RU Apps. The link to RU apps is https://apps.rutgers.edu/novnc/

 You will need to click on “connect” to the upper right part of the screen and then log in with your net id and password on the black box that you will get once you click the apps link. Next, you will get a blue screen, scroll all the way down and click on “Menu” on the lower left part of the screen. Next click on “Education” then choose “STATA”. The trick is, you need to have your data saved under your RU home directory (H:). Once you have it there you can access it and use it through STATA. Please note that data saved on USB will not be accessed through the RU apps website. The only accessed files are those saved under your H directory. You can upload your files to the H directory through the Scarlet mail account (assuming you have one, it is the most recent one).               To upload a file you should be able to go to the website http://scarletmail.rutgers.edu/index.php [1], on the left side click on Scarletdocs, sign in with your netid username/password, under drive & next to create click on the up arrow, click files, choose the file you would like to upload, and choose open. If you have a clam account you can use a program like Webdrive, secure shell client (use the ssh secure file transfer), or some other program to connect to clam.rutgers.edu, use your clam userid & password, and the default port 22. Now go to apps.camden.rutgers.edu, type in your netid username/password, click connect, open firefox (on this Linux server not your local computers firefox), and follow the steps up to the point of getting to your scarletdocs. When you click on scarletdocs you should see in the middle of the page what you had uploaded. If you have questions regarding accessing STATA from off campus, please contact help@camden.rutgers.edu.

WEB ACCESS

The course web page is available on Sakai however all the course materials will be posted on MindTap, which can be accessed via Sakai. All the announcements, assignments, additional resources to accompany each chapter, and a secure gradebook will all be available on MindTap website. You are responsible for checking announcements, grades, and discussion board frequently. Here are the instructions for MindTap via Sakai:

  • Login to your Sakai Course.
  • Click on the link to Cengage content, which is identified with a Cengage Learning logo.
  • Link Your Cengage account with your campus Sakai account.  If you do not have a Cengage account, create one from this page. Note: This is a one-time process.  If you have previously taken this step you will be taken directly to the payment options screen. ·        
  • Pay for Access. You’ll have two payment options:
    • Option 1: Purchase online
    • Option 2: Already purchased an access code? Redeem your code here.
  • I suggest that students just purchase the Mindtap code w/ebook: http://www.cengagebrain.com/shop/isbn/9781305404250

ONLINE FORMAT

This course offers readings, lecture material, frequent assessments, and online activities, including active discussions and exercises. There are no scheduled meeting times, but deadlines are strictly enforced, as students work together to achieve learning objectives. The class follows a rigorous schedule and you should expect to be working at least as many hours as with a traditionally-scheduled class. Plan to log into Sakai/MindTap and work almost every day, as we complete a semester’s worth of learning activities.

ASSIGNMENTS

There will be a total of five assignments. The five assignments will count a total of 25% toward your final grade.   The assignments consist of a series of multiple-choice questions. You will have ONE WEEK to finish and submit the assignment. The post dates for the assignments are Mondays September 12, September 26, October 10, November 7, and November 28. The due dates for the assignments are Mondays September 19, October 3, October 17, November 14, and December 5.

QUIZZES

There will be a total of nine quizzes, which will count, total of 15% toward your final grade. These quizzes are posted for ONE DAY. The post dates for the quizzes are Fridays September 16, October 7, October 14, October 21, November 4, November 18, December 2, and December 9.

ONLINE DISCUSSIONS

We’ll use the Forums tool in Sakai to engage in meaningful and graded discussions almost every day. The online discussions will count a total of 20% toward your final grade. I expect you to make a substantive post for each discussion topic, as well as a substantive response to a classmate’s post. Note that each discussion topic will present two deadlines: one for the initial post and one for the response. You can expect me to access the discussion forum regularly and contribute to the conversation. Discussion grades will be posted in Sakai generally within one day of the discussion closing date. Topics are available Monday morning, and discussions close at 11pm Sunday. You must post/respond at least once Monday-Wednesday, and at least once Thursday-Sunday. By 11pm of Wednesday of each week post your first discussion contribution; Thursday-Sunday: follow-up posts in online discussion; Sunday by 11pm: complete posts. Your participation will be graded based on how well you meet these criteria:

ACADEMIC INTERGRITY

The consequences of scholastic dishonesty are very serious. You are responsible for reading and understanding our policy on academic integrity policy, available from the Rutgers Academic Integrity website. Academic integrity means, among other things, that all Rutgers students are required to:

  • Properly acknowledge and cite all use of the ideas, results, or words of others
  • Properly acknowledge all contributors to a given piece of work
  • Make sure that all work submitted as his or her own in a course or other academic activity is produced without the aid of unsanctioned materials or unsanctioned collaboration
  • Treat all other students in an ethical manner, respecting their integrity and right to pursue their educational goals without interference. This requires that a student neither facilitate academic dishonesty by others nor obstruct their academic progress

STUDENTS WITH DISABILITY

Students who have a diagnosed disability on file with the Office of Disability Services are eligible for accommodations, as specified by the University. Please contact the Office of Disability Services at 856-225-6442 if you need to begin the process of receiving accommodations. Students who do not have a letter of accommodation from the university will not be eligible to receive accommodations in this course.
