Bank Portfolio Restrictions and Equilibrium Bank Runs
نویسندگان
چکیده
and Headnote We put “runs” back in the bank runs literature. A unified bank, one that invests in both liquid and illiquid assets, can easily avoid runs but it still faces a small probability of non-run rationing of depositors. In a separated financial system, the bank only holds relatively liquid assets; it is subject to runs with small probability, but because of its overinvestment in the liquid asset it is immune to non-run rationing of depositors. Surprisingly, legal restrictions on the bank’s portfolio are either ineffective or they increase the fragility of the bank. Journal of Economic Literature Classification Numbers: D82, G21, E42.

We construct an endogenous growth model in which bank runs occur with positive probability in equilibrium. In this setting, a bank run has a permanent effect on the levels of the capital stock and of output. In addition, the possibility of a run changes the portfolio choices of depositors and of banks, and thereby affects the long-run growth rate. These facts imply that both the occurrence of a...
متن کاملHerding and bank runs
Traditional models of bank runs do not allow for herding e¤ects, because in these models withdrawal decisions are assumed to be made simultaneously. I extend the banking model to allow a depositor to choose his withdrawal time. When he withdraws depends on his consumption type (patient or impatient), his private, noisy signal about the quality of the banks portfolio, and the withdrawal histori...
متن کاملStress Tests and Bank Portfolio Choice∗
How informative should bank stress tests be? I use Bayesian persuasion to formalize stress tests and show that regulators can reduce the likelihood of a bank run by performing tests which are only partially informative. Optimal stress tests give just enough failing grades to keep passing grades credible enough to avoid runs. The worse the state of the banking system, the more stringent stress t...
متن کاملInformation Acquisition in Rumor-Based Bank Runs
We study the endogenous information acquisition and withdrawal-redeposit decisions of individual agents when a liquidity event triggers a spreading rumor and therefore exposes a bank to a run. Uncertainty about the bank’s liquidity and potential failure motivates agents who hear the rumor to acquire additional information. Although the bank run equilibrium is unique given the additional signal’...
متن کاملBis Working Papers Bank Runs without Self-fulfilling Prophecies Monetary and Economic Department
This paper proposes that bank runs are unique equilibrium outcomes instead of self-fulfilling prophecies. By assuming that depositors make their withdrawal decisions sequentially, the model provides an equilibrium-selection mechanism in the economy. A bank run would occur if and only if depositors perceive a low return on bank assets. Furthermore, a panic situation arises only when the market i...
