Classes - Fall 2009


180.671 Industrial Organization: This course explores firm and industry behavior with an emphasis on markets characterized by imperfect competition. The central issues addressed concern the determinants of the intensity of competition, entry and exit, industry dynamics, and market dominance. Course Web Page


Classes - Spring 2010


180.215 Game Theory and the Social Sciences: Game theory is one of the few mathematical tools developed for the purpose of understanding social phenomena. This course provides an introduction to game theory with an emphasis on applications, in economics, political science, business, military science, history, biology, theology and recreation. The required mathematical background is minimal - high school algebra is sufficient. Prerequisite: A sincere intent to attend class on a regular basis. Course syllabus
