Principles of Microeconomics

 Fall 2003

Course Description

 

Microeconomics is the study of the behavior of individual economic agents.  The basic concepts that every course starts with are opportunity cost and the model of supply and demand.  We will review these two topics.  Traditional courses then go on and talk about consumer behavior and the mapping to demand curves.  In this part of the paradigm there are assumed to be many buyers and many sellers, so many that everyone is a price taker.  Strategic interaction among economic agents is not considered. The next topic is production and costs of the firm.  Demand and the theory of the firm are brought back together again to model price and output decisions of firms in different market structures, usually four.  Again, except for some special cases, startegic behavior is overlooked.  Time permitting, the traditional course ends with topics that may include international trade, market failure, and/or welfare and general equilibrium.  The standard micro course, in overlooking strategic interaction and behavior, misses the richest part of studying economic behavior. Also, in intermediate microeconomic theory, Economics 201, the same topics are covered again with a bit more abstraction.

 

In my version of Economics 92 will spend the bulk of our time modeling strategic behavior.  The topics of the standard principles course become special cases or are embedded implicitly in the topics we will cover. Further, in order to spare you the topical repetition between 92 and 201, our course will be somewhat different.  After reviewing production possibilities frontiers and the supply-demand paradigm we will study the strategic behavior of economic agents using mathematical games.  We will begin with the simplest of all games, the prisoner’s dilemma, and learn about its representation as either a normal form game or an extensive form game.  We will work with games that involve simultaneous moves those that involve sequential moves.  We will talk about formulating a strategy for playing a game.  We will introduce some notions of equilibrium so that we can characterize the outcomes of games. Throughout there will be applications to every day events in life, industry and politics.

 

Some scholars in the area of game theory and strategic behavior have developed software, called GAMBIT, for solving games.  This is freeware that you will need to download and put on a computer that you commonly use.

 

We probably will not use any calculus, but you should be confident of your algebra skills.  We won’t review the rules of algebra.  However, I will introduce you to probability.  Some of you may have seen this already and you can help your peers who have not.
