Hétérogénéité des banques et des circuits de financement et régulation monétaire
We study the variability of interest rates and of bank's profits in an economy where banks are heterogenous (they differ in their share in the deposits market and in the nature of the firms they lend to) as well as borrowers (some of them have only access to bank credit while others can directly issue bonds). The results depend on the choice of the instruments of monetary policy and on the more or less competitive nature of the bank credit market.
