The Role Of Interbank Markets In Monetary Policy: A Model With Rationing
Source: Universitat Pompeu Fabra
This paper analyses the impact of asymmetric information in the interbank market and establishes its crucial role in the micro foundations of the monetary policy transmission mechanism. The authors show that interbank market imperfections induce equilibrium with rationing in the credit market. This has two major implications: first, it reconciles the irresponsiveness of business investment to the user cost of capital with the large impact of monetary policy (magnitude effect) and, second, it shows that banks' liquidity positions condition their reaction to monetary policy (Kashyap and Stein liquidity effect).
