Course Description: This course is the first part of a one-year economics sequence and focuses on mi-

croeconomics. The objectives of the course are (i) to provide you with the analytical tools that are needed

to understand how economists think and (ii) to help you to develop an open-minded and critical way of

thinking about economic issues. The course content also links to public policy and considers various appli-

cations and normative viewpoints. At the end of the course, you will understand the concepts that underlie

microeconomics models and the jargon used in the economic profession. Most importantly, you will be able

to critically assess arguments made in current policy debates.

Communication, Office Hours, and Attendance: Continual interaction with the subject matter is an

important component to your ultimate success. We will be available during office hours and if you are having

problems do not hesitate to get in contact with us. Most importantly feel free to email us with questions

or concerns you may have about the course or your success. Attendance of each lecture and recitation is

strongly recommended and incentivized but not required. If you do not attend class, you should be able to

take responsibility for the material you missed and ask your fellow students for class notes. For office hours

and locations please check the course’s CourseWorks website at https://courseworks2.columbia.edu.

Textbook:

? Austan Goolsbee, Steven Levitt, and Chad Syverson. “Microeconomics,” Worth Publishers.

The book is recommended and intended to provide you with a complementary textbook that covers the ana-

lytical and intuitive elements of the lecture. Your reliance on the access to the textbook may be a necessary

condition for success in this course. Any edition or other intermediate microeconomics book is acceptable.

The book is available at the Columbia Bookstore and other retailers (Bookculture at 536 W 112th St., ama-

zon.com, borders.com, abebooks.com, etc.).

Course Reserve: The following texts will be on reserve in Lehman Library:

Austan Goolsbee, Steven Levitt, and Chad Syverson. “Microeconomics,” Worth Publishers.

Grading Policy: The graded coursework will consist of problem sets, two midterms, and a final exam.

Your final course grade will be determined as follows:

20% Assignments

25% Midterm 1 – Friday, 9/27

25% Midterm 2 – Friday, 11/1

30% Final – Friday, 12/131

At times students will be called upon to participate in discussions. I will expect students to participate in

these discussions, and at times, such participation may be included in final grades.

The lowest score of your problem sets will be dropped at the end of the semester. This accommodates

any unforeseen events that may occur and prevent you from submitting a problem set on time. In no

event a problem set will be accepted after the solutions have been posted.

Each exam is two hours. More specific details about exams will be given approximately a week before

exams are to be taken.

Failure to take any of the exams will result in a failing grade for the class. Please let me know by

September 19th if you cannot make any of the exams.

Excused absences from exams will be allowed only for serious medical problems, important university

affairs, or severe personal matters. You must notify me by email, as soon as possible and no later than

48 hours after an exam in order for me to even consider such a request.

If you are excused from a midterm but have not told me before September 17th, then a make-up

midterm will be scheduled during Finals Week in December.

Letter grades for the course will be assigned based on relative performance and SIPA’s policies and

according to the overall performance of all sections.

There will be no special treatment for any student. Special treatment refers to individual exceptions

that are not granted to other students who are in a similar situation (e.g., extra credit, extensions,

etc.).

Recitations: There are almost weekly recitations. The recitations are intended to give you an opportunity

to practice applying the concepts covered in lecture and to practice for exams. Each recitation covers the

same material and you can attend your preferred recitation. For recitation times and locations please check

the course’s CourseWorks website at https://courseworks2.columbia.edu.

Homework: During the semester you will be assigned homework problem sets. Most problem sets are

handed in individually or by study groups depending on the type of assignment. You are highly encouraged

to work with any of your fellow students if not otherwise specified. However, do not copy or plagiarize

anybody’s work (classmates, answer keys, etc.).

Grading Appeals: Any requests for re-grading on an exam must be submitted in writing within one week

of when the exam is handed back or the score is posted on CourseWorks. A re-grading request should

include an argument for why you feel your answer was correct. I reserve the right to re-grade the entire

exam when a request to re-grade a specific question is made. If an administrative error has been made in

determining your score (such as an arithmetic or uploading error), then just bring it to my attention after

lecture. If you find a mistake or inconsistency on a provided answer key, please contact me as soon as possible.

Academic Misconduct: The Code of Academic & Professional Conduct Code defines academic miscon-

duct. Students are prohibited from committing or attempting to commit any act that constitutes aca-

demic misconduct. If there is any question about whether an act constitutes academic misconduct, it is

your obligation to clarify the question with me before committing or attempting to commit the act. The

Code of Academic & Professional Conduct Code and additional information about a common form of aca-

demic misconduct, plagiarism, is available at http://bulletin.columbia.edu/sipa/academic-policies/

academic-and-professional-conduct/.

Sanctions for Academic Misconduct: Any violation of academic integrity results in an incident re-

port that will be filed with SIPA’s Student Affairs and subject to the Dean’s Discipline Procedures as

well as a grade penalty such as a failing grade of “F.” Additional information can be found at http:

//bulletin.columbia.edu/sipa/academic-policies/discipline-procedures/index.html.

Generative Artificial Policy: You can use AI tools to check and correct language mistakes (e.g., Gram-

marly). Please refrain from using generative AI tools to draft emails you are sending me or submitting

coursework (e.g., ChatGPT). In all circumstances, please remember that you are assessed on understanding

and applying the course’s material and that human interactions facilitate learning.

Students with Disabilities: SIPA is committed to ensuring that students registered with Columbia Uni-

versity’s Disability Services (DS) receive the reasonable accommodations necessary for their full participation

in their academic programs. If you are a student with a disability and have a DS-certified accommodation

letter, please make arrangements with me in week 1 or as early as possible. Please contact and ask SIPA’s

DS liaison at disability@sipa.columbia.edu and/or 212-854-8690 to send me a letter confirming your recom-

mended accommodations.

Website: I will use the course’s CourseWorks website to disseminate scores, announcements, class material,

assignments, and other course documents. The website can be accessed through https://courseworks2.

columbia.edu. Announcements made on the website are considered modifications to the syllabus.

Similarities and Differences with U6400: Both U6300 and U6400 are applied intermediate microeco-

3

nomics courses, which rely more heavily than undergraduate courses on real-world examples as a tool to

understand economic concepts and ideas. The topics covered in the two courses are the same. However,

U6400 is more calculus-based, the pace of the course is faster, and the workload is heavier. Which of the two

courses suits you better depends on your ability to work with mathematics and curriculum plans. Because

many economic arguments are easier to understand with mathematics, if you are comfortable with rigorous

logical reasoning, U6400 may be more comfortable than U6300. In most cases, you can choose whether to

take U6300 or U6400. However, because several programs, concentrations, or courses require you to take

U6400, please check with your program or concentration director to make sure you can choose.
