Professor: Lucie Ménager, Panthéon-Assas University

Objective: This course is an introduction to microeconomic theory of banking, which has developed since the 70’s mainly through a switch of emphasis from the modeling of risk to the modeling of imperfect information. This asymmetric information model is based on the assumption that different economic agents possess different pieces of information on relevant economic variables, and that they will use the information for their own profit. The model has been extremely useful in explaining the role of banks in the economy. It has also been useful in pointing out structural weaknesses of the banking sector that may justify government intervention--for example, exposure to runs and panics, the persistence of rationing in the credit market, and solvency problems. We will focus on why financial intermediaries exist, optimal contracting between lenders and borrowers, the equilibrium of the credit market, individual bank runs and systemic risk.
