ECON-UA 316 Industrial Organization
Spring 2026 Syllabus
1 Course overview
Industrial Organization examines a wide range of firm behaviors in imperfectly competitive markets. How do firms acquire and exercise market power—the ability to set prices above marginal costs? What strategic actions do firms take to capture business from rivals and extract more surplus from consumers? How should governments design efective competition policies? This course will introduce you to the mathematical models that help answer questions like above. We will also draw on real-world examples of firm behavior and market structures to illustrate these concepts.
Prerequisites You should be comfortable with microeconomic theory and mathematics (algebra, calculus) at the level of ECON-UA 10 Intermediate Microeconomics or equivalent. This course will require you to take derivatives and the occasional integral.
Course structure This course will primarily be a lecture-based course with exams and problem sets. However, I highly encourage you to come with thoughts and questions about the explicitly assigned readings. Announcements, assignments, and readings will be posted on the course website in Brightspace.
Textbook and references This course will rely primarily on lecture materials, which will include a com- bination of black/white-board work and slides. I will post slides shortly before the lecture. The following textbook will be the main reference for materials in the course:
Luis Cabral, Introduction to Industrial Organization (MIT Press)
I will also sometimes reference news articles, academic papers, and other materials. These materials (or links to these materials) will be posted on the course website.
2 Grading
The course grade will be based on:
1. Problem sets (worth 20% total): There will be 4 problem sets during this semester. Your lowest-scoring problem set will be dropped, and the remaining 3 (highest-scoring) problem sets will have equal weights.
Problem sets are due by 11.59pm of the due date. Due dates for the problem sets are currently scheduled as follows:
- Problem set 1: Friday 02/13 (Demand, Monopoly)
- Problem set 2: Friday 03/06 (Basic Game Theory, Static Models of Competition)
- Problem set 3: Friday 04/03 (Dynamic Models of Competition)
- Problem set 4: Wednesday 04/29 (Merger Analysis, Vertical Markets, Networks/Platforms)
The problem sets are meant to help with your learning. Each student must write up and submit their own problem sets. Explicitly copying someone else’s work is not allowed. However, you are encouraged to work with your peers on assignments. It is up to you to make sure that you understand all problems.
Please include the names of your collaborators (max 3) on your assignment.
Every student has a 24-hour grace period for one problem set. Note that you must inform the TA via email that you are using this option before the problem set deadline for the grace period to be efective. Any problem set submitted after the allowed grace period, or any additional problem set that misses the deadline after the grace period has been used will be counted as 0.
To reward your engagement with the material, problem sets are graded leniently. Partial credit may be given for reasonable attempts. Receiving full points does not necessarily mean that all answers are completely correct: it is recommended that you check your solutions against the answer key. Exams will be graded more strictly than problem sets.
2. Quizzes and Class Participation (worth 15% total):
• Short Quiz 1: 02/17
• Short Quiz 2: 03/04
• Short Quiz 3: 04/15
Your lowest-scoring quiz will be dropped, and the remaining two (highest-scoring) quizzes will have equal weights. There are no make-up quizzes. However, asking/answering questions in class earns bonus points that count toward this category (for a maximum of 3 percentage points).
3. Exams (worth 65% total): Please make sure that you are available on the exam dates. There are no make-up exams or extra credit opportunities. Note, if you perform better on the final than the midterm, the final will be weighted by more:
(a) Midterm Exam (30% or 20%): 03/11
(b) Final Exam (35% or 45%): 05/04. The final is cumulative and will cover materials for the whole semester.
You are permitted to use a scientific calculator during the midterm and final exams (phones and other online references are not allowed).
3 Course policy
Grading policy
- All your submitted work must abide by the NYU Honor Code.
- Questions regarding grades of problem sets/exams must be raised within one week from the date the grades are posted to NYU Brightspace.
- If you request a regrade for any part of a question in a problem set, quiz, or exam, the entire problem set or exam will be regraded.
- Grade letter distribution for the course will be based upon the Economics Department guidelines: “Deviation of plus or minus five percentage points is considered within the normal bounds for the following targets: A 29%; B 40%, C 31%, D when appropriate; F when appropriate.
Accommodation NYU’s Policy on Academic Accommodations for Religious Holidays and Observances states that students may, without penalty, excuse themselves from academic obligations and otherwise re- ceive a reasonable accommodation when required for religious and spiritual holidays and observances. You must notify me in advance (at least two weeks) of religious holidays or observances that might coincide with exams, assignments, or class times to schedule reasonable alternatives. Students may also contact [email protected] for assistance.
Email guidelines
- If you need to reach me or the course TA by email, please include “ECON316” in the subject of your email, otherwise your email may get lost in the shuffle. If the questions are about class materials, you should reach out to the TA first, especially during recitations and office hours.
- If you email me, do not expect an immediate answer, especially if it is on the weekend or late at night. If you email me and I do not respond within 48 hours, then feel free to email me again.
- If I receive many emails asking the same thing, I may post a class wide announcement rather than responding to each email individually.
Cell phone policy Using phones during class is not allowed. If you have to use your phone because of an emergency, please leave the class to deal with the emergency.
