We often say that microeconomics deals with incentives. However, in much of undergraduate microeconomics, by assuming that agents (firms, households, etc.) are small in the relevant markets, we are able to characterize choice in ways that seem strangely asocial. Agents do not so much interact with each other as they respond to impersonal (primarily price) signals. As a result, incentive issues do not arise in a serious way. While much of our economic life is well-understood through such models, there are large parts of our economic life in which we have some market power due to the fact that we have private information. The purpose of this course is to extend the tools developed in intermediate microeconomics to a variety of (primarily economic) situations in which at least some agents possess private information and examine the kinds of mechanisms that exist to deal with the problems created by such private information. Among the situations we will examine are: the relations between managers and employees; the relations between stockholders and mangers; the relations between insurance companies and potential clients; the relations between sellers and buyers of used cars; provision of public goods; and many more. In all of these cases the existence of private information, along with self-interested behavior on the part of all agents, can result in the failure of agents to make mutually beneficial contracts. Thus, in all of these cases we will first seek to characterize the relationship in such a way that the effect of private information becomes clear, and then we will seek to understand the social institutions that help us overcome these problems. Our strategy will be to focus on the main principles by studying examples, not by seeking to prove very general results.
These issues are at the frontier of modern microeconomic and political-economic research. While we will not pursue a rigorous theorem-proof approach, this is a course in economic theory. Intermediate microeconomics (Economics 301) is a serious prerequisite. Although we will be working with illustrative examples, we will be using logic, algebra, geometry, and simple calculus extensively.

We will draw supplementary reading from a variety of journal articles.

Your performance in the course will be evaluated on the basis of a two mid-term examinations a final examination, and a large number of homework assignments. The midterms will be given on 27 September and 25 October, and the final exam will be given only on Saturday, 15 December 2007, 1:00pm. Because much of the course will involve discussion of the reading and the homework, attendance is mandatory, as is timely completion of homework.
