This course consists broadly of the study of the price and efficiency performance of industries representative of various types of market structures and practices. Recent developments in game theory have proven to be very useful in interpreting the facts of industrial economics in the U.S. Along with a consideration of actual structure and performance, relatively simple game theoretic models of industrial organization will be analyzed. Among the topics that will be analyzed may be: the role of a firm's reputation, tacit collusion, sunk costs and barriers to entry, multimarket contact, patent races, strategic adoption of new technologies, and wars of attrition. Format: lecture/discussion. Requirements: There will be several problem sets and exams throughout the semester. A paper will also likely be required. Prerequisite: Economics 251. Enrollment limit: 25.
