“…Bhattacharya and Gale (1987), Bhattacharya and Fulghieri (1994), Freixas et al (2000) and Allen and Gale (2000), for instance, extend the standard banking model of Diamond and Dybvig (1983) to a multi bank setting and study how the structure, efficiency and resilience of the interbank market is affected if banks' idiosyncratic liquidity needs are private information. Rochet and Tirole (1996), Freixas and Holthausen (2005), Freixas and Jorge (2008), and Heider et al (2009) model the implications that asymmetric information of borrowers' credit risk has on tiering in the interbank market as well as on credit risk spreads and potential freezes in the unsecured interbank market. 3 However, none of these theoretical papers studies how the repeated interaction between banks affects these informational asymmetries and their implications.…”
