Course Description.  We will study the theory of industrial organization, focusing on understanding the way firms make decisions and the effects of those decisions on market outcomes like prices, quantities, the type of products offered, and social welfare. Fundamental questions pursued in this course include: Why are markets organized the way they are? How do the ways in which a market is organized affect firms' behavior? How does the behavior of firms affect the structure of markets and market outcomes? Our primary approach to addressing these questions will be analysis of formal theoretical models.    The goals of the course include development of intuition for pricing and other strategic behavior by firms, and development of skills for analysis of formal models.  Readings in the textbook will provide background and introduction to a variety of topics, many of which will be covered in class in greater depth.  Lectures, problem sets, and exams will be the core of the course and will focus on formal analysis.  Occasional supplemental readings will provide additional motivation, applications, and opportunities to develop intuition. 

Prerequisites.   The formal pre-requisite is intermediate micro.  On very rare occasions I will give permission to take the course to student who has not yet taken intermediate micro.  All students should be comfortable using basic calculus to solve problems.  We will not use a great deal of math, but we will use a little math a great deal.  I will teach any math needed beyond what is covered in a first calculus course.    

Class Web Page  Problem sets and solutions will be posted here.  There will also be contact information, a copy of this syllabus, supplemental readings, problem sets, and a log of class announcements.

Exams. There will be midterm exam and a final exam. The MIDTERM EXAM will be given IN CLASS THURSDAY FEBRUARY 28. The FINAL EXAM will be held at 9:00 a.m. on  MAY 12.

Problem Sets will typically be assigned every one to two weeks and graded, mainly  for completeness.  The problem sets are a critical component of the course.

Readings.   The textbook for the course is Industrial Organization, A Strategic Approach, by Church and Ware.  It is available free in PDF format from the class web page or at  http://homepages.ucalgary.ca/~jrchurch/page4/page5/files/PostedIOSA.pdf   You may be able to find used copies on the internet if you prefer a bound hard copy.  Additional readings from other sources (newspaper articles, lecture notes, journal articles, etc.) will occasionally be assigned

Grades will be based on problem sets (25%), the midterm exam (37.5%) and the final exam (37.5%).
