Course content

This course is being discontinued after spring 2019. The last exam is in fall 2019.

  • General equilibrium analysis including the main welfare theorems.
  • An introduction to the economics of information, presenting models of moral hazard, adverse selection, and signalling.

Learning outcome

Knowledge outcomes:
In the first part of the course students are expected to obtain knowledge of the result that a general equilibrium exists, and an understanding of the intuition underlying the main welfare theorems both in general and partial equilibrium analysis. In the second part of the course students are expected to learn the basic concepts and results of the economics of information. This part considers models of asymmetric information, and introduces the concepts of moral hazard, adverse selection, and signaling.

The students should be able to do do welfare economics without use of marginal conditions. The students should realize that many forms of economic interaction involve problems of asymmetric information, and be able to differentiate between problems of moral hazard, adverse selection, and signaling. The students should be able to handle simple models that capture various kinds of informational asymmetry.
