“…4,5 1 Allen et al (2011, chapter 3) identify five sources for systemic risk: common exposure to asset price bubbles; mispricing of assets; fiscal deficits and sovereign default; currency mismatches in the banking system; maturity mismatches and liquidity provision. A growing literature examines a wide range of channels through which contagion in the banking sector may occur, such as common asset exposure (Acharya, 2009;Ibragimov et al, 2011;Wagner, 2010), domino effects through the payments system or interbank markets due to counterparty risk (Allen and Gale, 2000;Dasgupta, 2004;Freixas and Parigi, 1998;Freixas et al, 2000;Rochet and Tirole, 1996), or price declines and resulting margin requirements (Brunnermeier and Pedersen, 2009). Beyond these recent events, the contagion of deposit withdrawals across banks has been documented for the U.S. during the Great Depression (Calomiris and Mason, 1997;Saunders and Wilson, 1996) as well as more recently in emerging markets (De Graeve and Karas, 2010;Iyer and Puri, 2012). However, the existing literature provides only scarce guidance on which underlying economic and informational conditions may foster contagious bank runs.…”
