This course studies the relationships between economic agents
when information is imperfect and asymmetric. That is, when there is
relevant information not known to some of the decision makers.
The course concentrates on contract design
in the presence of moral hazard (One participant may take
actions that affect both participants, but these are not observed by the
other participant);
Adverse selection (One participant has relevant information
concerning the pre existing situation, that may affect the payoffs of both);
And signalling (One of the participants has private information
useful for both, but has to take costly actions in order to reveal that
information).
