Class Time: TR 3:30  4:50 pm
Classroom: Tyler Hall 219
Course Summary¶
In this course we will explore econometric techniques for testing microeconomic theories at the individual or firm level. With the advent of computers and associated data on economic behavior, the past few decades has seen an explosion of applied economic research using a wide range of techniques for this type of data termed cross section data and cross section econometrics. In this course, you will learn about these techniques, will learn to be an educated consumer of econometric research, and will apply these techniques to real data. We will also derive many of the properties of the statistical techniques used in this course, but primarily at the end of the course you will
 Understand the strengths and weaknesses of cross section techniques
 Know how to test the validity of modeling assumptions
 Know the proper econometric technique for a wide variety of CrossSection settings

Email Policy : I will respond to emails but only if they contain the tag
[ECON407]
or[PUBP615]
in the subject line or you use the email exactly as specified above. If not, the google will likely delete your email. Emails must contain concise questions no longer than what would be amenable to respond to email. If you use the email address listed at the top of this page, it will autotag the email. 
Grades: Your grade will be based on five exercises (1 @ 5% and 4 @ 10% each), one midterm (25%), a final exam (30%).
 The problem sets will consist of a mix of theoretical and practical econometrics. In each (after the first one), you will be given a dataset and will need to conduct an econometric analysis thinking critically about which technique to employ as well as key tests that should be run. Your document should include clear interpretations of your results, tables with clear variable names, and be wellformatted with code, tables, and writeup combined in a convenient (for me) way. You will be responsible for posting to the blackboard assignment a markdoc (for
stata
) or Rmarkdown (forR
) file that completely generates your analysis: a flowing narrative containing code, writeup, and results. For any part of the problem sets requiring handwritten math excercises, you can turn those in on paper. Early on in class, I will demo how this works forstata
.  The midterm is scheduled for October 18 just after fall break. Unfortunately, I can't reschedule either the midterm or the final the exam, so if this time doesn't work for you please drop the course.

 Policy on Late Assignments : University policy will not allow me to reschedule the final exam (see the Dean of Students for exceptions). Course assignments must be turned in on time. Late work will be accepted for up to two additional days (with Saturday and Sunday counting as 1 day in total) with a letter grade deduction for each late day. After two days, late assignments will not be accepted. See below for some examples:

Thursday  Monday  A  F (not accepted) 
 Hardcopy Policy : For all problem sets, in addition to the file you post to blackboard, you will be responsible for turning in a hardcopy version of your work at the end of class. You may give it to me in person, put it in my box in Tyler Hall, or slide it under my door in Tyler Hall 252. Should you not give it to me in person and the work goes missing, you remain responsible for getting me your work on time to avoid late assignment penalties.
 Grade Discrepancies and Grade Questions : I am happy to discuss questions you have about your grade on class assignments. Any questions you have regarding a potential grade change on an assignment must be cleared up within 1 week of receiving your work back from me. The only exception to this policy is if I made an arithmetic or data entry error in adding your score up and entering it into blackboard.
 Course Materials All course materials are available on my website for this course at the links listed below. I will only be using blackboard for posting grades and problem set solutions.

Data (for stata and R ) 
Found at http://rlhick.people.wm.edu/econ407/data

 Book : The required book for the class is Greene's Econometric Analysis. This book is expensive. Instead, you may want to pick up an older edition which can be found at less than half the price. There may be minor differences in chapter names and content, but the models we are studying this semester are wellestablished and the content of either will be sufficient for our needs. With the money saved, you can pick up this one by Wooldridge which is recommended but not required (older editions of this one is also available).
Computing, Computers, and the Class¶
 We will make extensive use of
Stata
(or if you optionally decide to use it,R
). Forstata
you may want to buy your own copy of the software (through theGrad Plan
at stata.com) and the cost is around \$100. Alternatively, a Collegeowned version especially well suited to very large data sets can be run remotely on a Unix machine (stat.wm.edu
) from your laptop through X11 or other means. If you decide to go this route, know that the startup costs are higher and you will likely need assistance from IT to get everything set up. If you plan on usingstat.wm.edu
, please deal with these logistics during the first week of class. Additionally, there are computer labs around campus (e.g. Morton 240) where stata is accessible.R
is free for you to install on as many machines as you like, is opensource, and is also available on lab computers.  Computers: We will make some use of the main computer in the classroom for much of what we do together in class. The data for course examples and problem sets will be available on the web for the duration of the course, but you should have archival copies and working backups of all of the programs you have written to take the data from raw to final form. All computer work you do in this class must selfgenerate the full analysis and writeup using
markdoc
orRmarkdown
as described above.  The class: Ensure that you understand the material before we move past it. Ask questions. We will on many classroom occasions employ actual data and Stata, and you may want to follow along on your own computers. I encourage you to bring your computers to class.
Acceptable Collaboration¶
Finally, I want to define acceptable collaboration. In this course, I want you to think for yourself in applying these techniques. Using resources outside of class and properly citing it, is perfectly within bounds. Taking ``.do'' files from your fellow classmates or off of the web and treating them as your own work is not acceptable. Receiving assistance at every critical modeling step is also not acceptable. Asking a classmate about clarification of stata syntax (e.g. I forgot how to ask for robust standard errors, could you help me with that?), is fine.
