Economics of Asymmetric Information

Lecturer: Prof. Roland Strausz (Humboldt‐Universität Berlin)
Date: February 28, 2011 – March 2, 2011 (Universität Leipzig), daily from 09:30 – 16:00
Venue: Universität Leipzig, Grimmaische Straße 12, Room: SR S 211, Seminargebäude

Course Description

The course gives an advanced (PhD‐level) introduction to the economics of asymmetric information and points students towards active research questions. It first identifies how different types of asymmetric information affect markets and bilateral economic relationships. It thereby identifies and classifies the different types of asymmetric information and the standard economic models that capture them. It, secondly, discusses by example how these standard models are currently applied and extended in recent research.

Course Outline

1 Asymmetric information in markets
1.1 Adverse selection in markets
1.2 Signaling in markets
1.3 Screening in markets

2 Asymmetric information in bilateral relationships
2.1 Hidden actions (moral hazard)
2.2 Hidden information (monopolistic screening)
2.3 Mixed models and an application to monopoly regulation

3 Current Issues in mechanism design and organization theory
3.1 Revelation principles
3.2 Dynamic mechanism design
3.3 Organizational Design
