Course Description and Learning Goals


Welcome to microeconomics! It is a pleasure to be your teacher.


Economics studies how agents make decisions under conditions of scarcity and uncertainty. This course provides a rigorous introduction to economics, with special emphasis on microeconomics. It will introduce you to economics as a discipline and as a way of thinking. It will also provide you with a set of tools, which will be very useful in other economics courses.


We will first study the behavior of individual consumers and firms. Then we will give you some insight into how markets work and whether market outcomes are desirable.  We will also look at situations in which the firm is a monopolist, or competes with a limited number of rivals. Some key concepts we will introduce include economic incentives, marginal analysis, opportunity cost (which costs matter), market efficiency (what does it mean for a market to work) and strategic behavior (how to predict and respond to your rivals’ decisions).


The tools that you will be acquainted with in this class are fundamental for most upper division courses of the Economics major as well as classes in Finance, Accounting and Marketing.


Textbook: Robert S. Pindyck, and Daniel L. Rubinfeld:  Microeconomics (7th Edition or 8th Edition), Prentice-Hall Series in Economics.The textbook can be bought at the NYU Bookstore.[1]


[1] You can also use previous editions of the textbook or the international edition (see the topics in week 9 on price discrimination) as long as you make sure that you can figure out the sections of the book that we will cover.

Course Outline


Week 1:

Mon Jan 28:  Introduction and Preliminaries: what is Economics?  The study of how a society uses its limited resources to produce, trade and consume goods and services.

            Chapter 1: Sections 1.1, 1.2


Wed Jan 30:The Basics of Supply and Demand. The demand Curve describes consumers’ choice, while the Supply Curve describes how much firms will produces.

Chapter 2: Sections 2.1, 2.2, 2.3, 2.4, 2.5


Week 2:

Mon Feb 4:  Consumer Behavior (1): Preferences

Chapter 3, pp. 67-78: Section 3.1


Wed Feb 6:Consumer Behavior (2): Utility and Budget Constraints.

Chapter 3, pp. 79-86: Section 3.2


Week 3:

Mon Feb 11: Consumer Behavior (3): utility maximization. How do consumers maximize their utility given the budget constraint. The use of utility maximization to derive Marshallian demand curves.

                        Chapter 3, pp. 86-92, pp. 95-100. Sections 3.3 and 3.5

Wed Feb 13:  Individual Demand: Study how utility maximizing choice of a good varies as Income Changes (Engel Curve), and as the price of the good itself changes (Demand Curve).

                        Chapter 4, pp. 111-125, Sections 4.1, 4.2


Week 4:

 Mon Feb 18:NO Class. President’s Day


Wed Feb 20:Market Demand:add up individual demands to get market demand. Discuss Elasticity of Demand, the responsiveness of demand to price.

Chapter 2, Sections 2.4



Week 5:

Quiz 1 in class Wed Feb 27



Mon Feb 25:  Production Part I: We introduce firms and how they decide to produce. A firm is described by how it can transform inputs such as labor and capital into outputs, which is called a production function. We also discuss marginal versus average product of labor and capital.

            Chapter 6, Sections 6.1, 6.2



Wed Feb 27:  Production Part II:Production with two inputs. The tradeoff between using more labor or capital is called the marginal rate of technical substitution. As well we discuss returns to scale, i.e. are larger plants more productive?

            Chapter 6, Sections 6.3, 6.4


Week 6:

Mon Mar 4: The Cost of Production: We discuss the difference between sunk costs and fixed costs and costs in the short run versus the long run.

            Chapter 7, Sections 7.1, 7.2, 7.3, 7.4, Appendix 7 pages 264-268


Wed Mar 6:Profit Maximization and Competitive Supply. We look at the firm’s decision to produce in a perfectly competitive market. If a firm is maximizing profits, then it sets marginal costs to marginal revenue.

            Chapter 8, Sections 8.1, 8.2, 8.3, 8.4, 8.5


Week 7:

Mon Mar 11:Midterm Review


Tuesday March 12: Midterm at 8-9:10 PM location TBD


March 18-March 24 Spring-break-ENJOY!!!!!


Week 8:

Mon Mar 25:The Analysis of Competitive Markets. We use the tools of Consumer and Producer Surplus to analyze the effect of a tax or rent control on the efficiency of a market.

            Chapter 9, Sections 9.1, 9.2, 9.3, 9.6


Wed March 27:  Externalities and Public Goods. In many situations your actions affect others indirectly. Does this affect market efficiency?  We will talk about the failure of several fisheries due to the externality problem.

            Chapter 18, Sections 18.1, 18.2, 18.6, 18.6


Week 9:

Mon April 1:Market Power: Monopoly and Monopsony (I). We analyze firms with market power that do not take the market price as given, but can choose the price of their products.

            Chapter 11, Sections 11.1, 11.2


Wed April 10:Choice under Uncertainty. Expected Utility and Risk Preferences. How do we make choices when certain variables such as income and prices are uncertain (making choices with risk)?

            Chapter 5, Sections 5.1, 5.2, 5.3







Week 11:

Quiz 2 in class the week of April 15


Mon April 15:Game Theory (I): Simultaneous moves. We examine strategic decision making, when you are interacting with a competitor. We look at dominant strategies and a solution concept called Nash Equilibrium.

            Chapter 13, Sections 13.1, 13.2, 13.3

Wed April 17:Game Theory II: Games Trees, Commitment & Threats. We look at sequential games in this lecture and the strategic role of commitment and threats.

                        Sections 13.5, 13.6, 13.7


Week 12:

Mon April 22:Monopolistic Competition and Oligopoly. We examine how firms set price or quantity when they have a single competitor (Bertrand and Cournot Competition).Part I

            Section 12.2 up to page 455, 12.3       


Wed April 24:Monopolistic Competition and Oligopoly. We examine how firms set price or quantity when they have a single competitor (Bertrand and Cournot Competition).Part II

Group Projects

Guidelines for Group Projects

Business activities involve group effort. Consequently, learning how to work effectively in a group is a critical part of your business education.

Every member is expected to carry an equal share of the group’s workload. As such, it is in your interest to be involved in all aspects of the project. Even if you divide the work rather than work on each piece together, you are still responsible for each part. The group project will be graded as a whole:   its different components will not be graded separately. Your exams may contain questions that are based on aspects of your group projects.

It is recommended that each group establish ground rules early in the process to facilitate your joint work including a problem-solving process for handling conflicts. In the infrequent case where you believe that a group member is not carrying out his or her fair share of work, you are urged not to permit problems to develop to a point where they become serious. If you cannot resolve conflicts internally after your best efforts, they should be brought to my attention and I will work with you to find a resolution.

You will be asked to complete a peer evaluation form to evaluate the contribution of each of your group members (including your own contribution) at the conclusion of each project. If there is consensus that a group member did not contribute a fair share of work to the project, I will consider this feedback during grading.



At NYU Stern we seek to teach challenging courses that allow students to demonstrate their mastery of the subject matter.  In general, students in undergraduate core courses can expect a grading distribution where: 

Note that while the School uses these ranges as a guide, the actual distribution for this course and your own grade will depend upon how well you actually perform in this course.



The process of assigning grades is intended to be one of unbiased evaluation. Students are encouraged to respect the integrity and authority of the professor’s grading system and are discouraged from pursuing arbitrary challenges to it.

If you believe an inadvertent error has been made in the grading of an individual assignment or in assessing an overall course grade, a request to have the grade re-evaluated may be submitted. You must submit such requests in writing to me within 7 days of receiving the grade, including a brief written statement of why you believe that an error in grading has been made.
