We study the welfare implications of self-fulfilling bank runs and liquidity requirements, in a growth model where banks, facing persistent possible runs, can choose in any period a run-proof asset portfolio. In this framework, runs distort banks' insurance provision against idiosyncratic...

How does the availability of alternative investment opportunities for banks' depositors affect the reaction of the banking system to aggregate liquidity shocks? And what are the implications, if any, for banking regulation? To answer these questions, I study a Diamond-Dybvig environment, where...

We propose a novel theory of banks' liquidity management and financial fragility. Banks hold liquidity and an illiquid productive asset, thereby engaging in maturity transformation, and insure their depositors against idiosyncratic and aggregate shocks. However, strategic complementarities in...

Does the level of deposits matter for bank fragility and efficiency? In a banking model with endogenous bank runs and a consumption-saving decision, we show that the level of deposits has opposite effects on bank fragility depending on the nature of bank runs. In an economy with panic-driven...

How does the presence of decentralized market-based liquidity channels affect financial liberalization and contagion? In order to answer this question, I extend the Diamond and Dybvig (1983) model of financial intermediation to a two-country environment, in which banks in each country enjoy a...

We study a novel mechanism through which systemic risk, in the form of self-fulfilling runs, forces the banks to hoard liquidity. To this end, we develop an environment where banks offer insurance to their depositors against both idiosyncratic and aggregate real uncertainty, by holding a...
